Google reCaptcha in Web API 2 c#

I have an ASP.NET Web API 2 Project. I am trying to read Google Captcha from the form.
I tried this Code:
public string Post(FoundingRequest model)
{
var response = Request["g-recaptcha-response"];
string secretKey = "my key";
var client = new WebClient();
var result = client.DownloadString(
$"https://www.google.com/recaptcha/api/siteverify?secret={secretKey}&response={response}");
var obj = JObject.Parse(result);
model.Captcha = (bool)obj.SelectToken("success");
....
}
but I am receiving an Error on the first line:
Cannot apply indexing with [] to an expression of type
'HttpRequestMessage'
why? and how to solve it? thank you

That method's body for me works fine:
const string secretKey = "YOUR KEY";
string responseFromServer = "";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://www.google.com/recaptcha/api/siteverify?secret=" + secretKey + "&response=" + response);
using (WebResponse resp = req.GetResponse())
using (Stream dataStream = resp.GetResponseStream())
{
if (dataStream != null)
{
using (StreamReader reader = new StreamReader(dataStream))
{
// Read the content.
responseFromServer = reader.ReadToEnd();
}
}
}
dynamic jsonResponse = new JavaScriptSerializer().DeserializeObject(responseFromServer);
return jsonResponse == null || bool.Parse(jsonResponse["success"].ToString());
Update
Regarding the comment, it can be checked on the client side
var response = window.grecaptcha.getResponse()
And then pass this variable to Web API
This is part of my client script:
if (typeof window.grecaptcha != 'undefined') {
var capResponse = window.grecaptcha.getResponse();
if (!capResponse || capResponse.length === 0) {
user.isCaptchaPassed = false;
//alert("Captcha not Passed");
return false;
}
user.gReCaptcha = capResponse;
}
"user" is JS object created before, which passed through JS to server. (AJAX call)

Here's how I did it. I don't use the ChallangeTs so I didn't bother
trying to figure out why it wasn't converting to DateTime properly.
Maybe someone else has that solved.
public class ReCaptchaResponse
{
public bool Success;
public string ChallengeTs;
public string Hostname;
public object[] ErrorCodes;
}
[HttpPost]
[Route("captcha")]
public bool Captcha([FromBody] string token)
{
bool isHuman = true;
try
{
string secretKey = ConfigurationManager.AppSettings["reCaptchaPrivateKey"];
Uri uri = new Uri("https://www.google.com/recaptcha/api/siteverify" +
$"?secret={secretKey}&response={token}");
HttpWebRequest request = WebRequest.CreateHttp(uri);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = 0;
HttpWebResponse response = (HttpWebResponse) request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader streamReader = new StreamReader(responseStream);
string result = streamReader.ReadToEnd();
ReCaptchaResponse reCaptchaResponse = JsonConvert.DeserializeObject<ReCaptchaResponse>(result);
isHuman = reCaptchaResponse.Success;
}
catch (Exception ex)
{
Trace.WriteLine("reCaptcha error: " + ex);
}
return isHuman;
}

I found the answer, I created a hidden input with a certain name and updated its value on Captcha call back. Code:
<input type="hidden" value="" id="recaptcha" name="recaptcha" />
<div class="g-recaptcha" data-callback="imNotARobot" data-sitekey="key"></div>
and the Javascript is:
<script type="text/javascript">
var imNotARobot = function () {
$("#recaptcha").val(grecaptcha.getResponse());
};
</script>
server side:
public string Recaptcha { get; set; }
and the model binder does all the work.

I assume this request is coming from a form, change this:
var response = Request["g-recaptcha-response"];
To this:
var response = Request.Form["g-Recaptcha-Response"];
Also Change this:
var result = client.DownloadString($"https://www.google.com/recaptcha/api/siteverify?secret={secretKey}&response={response}");
To this:
var result = client.DownloadString(string.Format("https://www.google.com/recaptcha/api/siteverify?secret={0}&response={1}", secretKey, response));

Send push to Android by C# using FCM (Firebase Cloud Messaging)

I am using this code to send notification message by C# with GCM, using Winforms, Webforms, whatever. Now I want to send to FCM (Firebase Cloud Messaging). Should I update my code? :
public class AndroidGCMPushNotification
{
public AndroidGCMPushNotification()
{
//
// TODO: Add constructor logic here
//
}
public string SendNotification(string deviceId, string message)
{
string SERVER_API_KEY = "server api key";
var SENDER_ID = "application number";
var value = message;
WebRequest tRequest;
tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
tRequest.Method = "post";
tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", SERVER_API_KEY));
tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value + "&data.time=" + System.DateTime.Now.ToString() + "&registration_id=" + deviceId + "";
Console.WriteLine(postData);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
tRequest.ContentLength = byteArray.Length;
Stream dataStream = tRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse tResponse = tRequest.GetResponse();
dataStream = tResponse.GetResponseStream();
StreamReader tReader = new StreamReader(dataStream);
String sResponseFromServer = tReader.ReadToEnd();
tReader.Close();
dataStream.Close();
tResponse.Close();
return sResponseFromServer;
}
}
but the GCM was changed to FCM. Is this same code to send the notification?
Where can I find the SERVER_API_KEY? Is the same solution?

firebase cloud messaging with c#:
working all .net platform (asp.net, .netmvc, .netcore)
WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
//serverKey - Key from Firebase cloud messaging server
tRequest.Headers.Add(string.Format("Authorization: key={0}", "AIXXXXXX...."));
//Sender Id - From firebase project setting
tRequest.Headers.Add(string.Format("Sender: id={0}", "XXXXX.."));
tRequest.ContentType = "application/json";
var payload = new
{
to = "e8EHtMwqsZY:APA91bFUktufXdsDLdXXXXXX..........XXXXXXXXXXXXXX",
priority = "high",
content_available = true,
notification = new
{
body = "Test",
title = "Test",
badge = 1
},
data = new
{
key1 = "value1",
key2 = "value2"
}
};
string postbody = JsonConvert.SerializeObject(payload).ToString();
Byte[] byteArray = Encoding.UTF8.GetBytes(postbody);
tRequest.ContentLength = byteArray.Length;
using (Stream dataStream = tRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse tResponse = tRequest.GetResponse())
{
using (Stream dataStreamResponse = tResponse.GetResponseStream())
{
if (dataStreamResponse != null) using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
//result.Response = sResponseFromServer;
}
}
}
}

Here is another approach of writing Notification Service inside ASP.Net REST API.
public async Task<bool> NotifyAsync(string to, string title, string body)
{
try
{
// Get the server key from FCM console
var serverKey = string.Format("key={0}", "Your server key - use app config");
// Get the sender id from FCM console
var senderId = string.Format("id={0}", "Your sender id - use app config");
var data = new
{
to, // Recipient device token
notification = new { title, body }
};
// Using Newtonsoft.Json
var jsonBody = JsonConvert.SerializeObject(data);
using (var httpRequest = new HttpRequestMessage(HttpMethod.Post, "https://fcm.googleapis.com/fcm/send"))
{
httpRequest.Headers.TryAddWithoutValidation("Authorization", serverKey);
httpRequest.Headers.TryAddWithoutValidation("Sender", senderId);
httpRequest.Content = new StringContent(jsonBody, Encoding.UTF8, "application/json");
using (var httpClient = new HttpClient())
{
var result = await httpClient.SendAsync(httpRequest);
if (result.IsSuccessStatusCode)
{
return true;
}
else
{
// Use result.StatusCode to handle failure
// Your custom error handler here
_logger.LogError($"Error sending notification. Status Code: {result.StatusCode}");
}
}
}
}
catch (Exception ex)
{
_logger.LogError($"Exception thrown in Notify Service: {ex}");
}
return false;
}

I have posted this answer as this question was viewed most and this server side code was written in VS 2015 in C# for sending push notification either single device based on device id or subscribed topic to Xamarin Android app
public class FCMPushNotification
{
public FCMPushNotification()
{
// TODO: Add constructor logic here
}
public bool Successful
{
get;
set;
}
public string Response
{
get;
set;
}
public Exception Error
{
get;
set;
}
public FCMPushNotification SendNotification(string _title, string _message, string _topic)
{
FCMPushNotification result = new FCMPushNotification();
try
{
result.Successful = true;
result.Error = null;
// var value = message;
var requestUri = "https://fcm.googleapis.com/fcm/send";
WebRequest webRequest = WebRequest.Create(requestUri);
webRequest.Method = "POST";
webRequest.Headers.Add(string.Format("Authorization: key={0}", YOUR_FCM_SERVER_API_KEY));
webRequest.Headers.Add(string.Format("Sender: id={0}", YOUR_FCM_SENDER_ID));
webRequest.ContentType = "application/json";
var data = new
{
// to = YOUR_FCM_DEVICE_ID, // Uncoment this if you want to test for single device
to="/topics/"+_topic, // this is for topic
notification=new
{
title=_title,
body=_message,
//icon="myicon"
}
};
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(data);
Byte[] byteArray = Encoding.UTF8.GetBytes(json);
webRequest.ContentLength = byteArray.Length;
using (Stream dataStream = webRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse webResponse = webRequest.GetResponse())
{
using (Stream dataStreamResponse = webResponse.GetResponseStream())
{
using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
result.Response = sResponseFromServer;
}
}
}
}
}
catch(Exception ex)
{
result.Successful = false;
result.Response = null;
result.Error = ex;
}
return result;
}
}
and its uses
// start sending push notification to apps
FCMPushNotification fcmPush = new FCMPushNotification();
fcmPush.SendNotification("your notificatin title", "Your body message","news");
// end push notification

Yes, you should update your code to use Firebase Messaging interface.
There's a GitHub Project for that here.

request.Method = "POST";
request.Headers.Add("Authorization", "key=" + this.key_server);
request.ContentType = "application/json";
string json = JsonConvert.SerializeObject(message);
//json = json.Replace("content_available", "content-available");
byte[] byteArray = Encoding.UTF8.GetBytes(json);

dynamic stuff = JsonConvert.DeserializeObject(result);
return stuff;
}
else
{
throw new Exception("Ocurrio un error al obtener la respuesta del servidor: " + respuesta.StatusCode);

Based on Teste's code .. I can confirm the following works. I can't say whether or not this is "good" code, but it certainly works and could get you back up and running quickly if you ended up with GCM to FCM server problems!
public AndroidFCMPushNotificationStatus SendNotification(string serverApiKey, string senderId, string deviceId, string message)
{
AndroidFCMPushNotificationStatus result = new AndroidFCMPushNotificationStatus();
try
{
result.Successful = false;
result.Error = null;
var value = message;
WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
tRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", serverApiKey));
tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value + "&data.time=" + System.DateTime.Now.ToString() + "&registration_id=" + deviceId + "";
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
tRequest.ContentLength = byteArray.Length;
using (Stream dataStream = tRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse tResponse = tRequest.GetResponse())
{
using (Stream dataStreamResponse = tResponse.GetResponseStream())
{
using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
result.Response = sResponseFromServer;
}
}
}
}
}
catch (Exception ex)
{
result.Successful = false;
result.Response = null;
result.Error = ex;
}
return result;
}
public class AndroidFCMPushNotificationStatus
{
public bool Successful
{
get;
set;
}
public string Response
{

set;
}
public Exception Error

You need change url from https://android.googleapis.com/gcm/send to https://fcm.googleapis.com/fcm/send and change your app library too. this tutorial can help you https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol

Try to send a json object.
Replace this:
tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value + "&data.time=" + System.DateTime.Now.ToString() + "&registration_id=" + deviceId + "";
Console.WriteLine(postData);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
For this:
tRequest.ContentType = "application/json";
var data = new
{
to = deviceId,
notification = new
{
body = "This is the message",
title = "This is the title",
icon = "myicon"
}
};
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(data);
Byte[] byteArray = Encoding.UTF8.GetBytes(json);

Here's the code for server side firebase cloud request from C# / Asp.net.
Please note that your client side should have same topic.
e.g.
FirebaseMessaging.getInstance().subscribeToTopic("news");
public String SendNotificationFromFirebaseCloud()
{
var result = "-1";
var webAddr = "https://fcm.googleapis.com/fcm/send";
var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add("Authorization:key=" + YOUR_FIREBASE_SERVER_KEY);
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{\"to\": \"/topics/news\",\"data\": {\"message\": \"This is a Firebase Cloud Messaging Topic Message!\",}}";
streamWriter.Write(json);
streamWriter.Flush();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}

You can use this library, makes it seamless to send push notifications using Firebase Service from a C# backend download here

public SendNotice(int deviceType, string deviceToken, string message, int badge, int status, string sound)
{
AndroidFCMPushNotificationStatus result = new AndroidFCMPushNotificationStatus();
try
{
result.Successful = false;
result.Error = null;
var value = message;
WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
tRequest.ContentType = "application/json";
var serializer = new JavaScriptSerializer();
var json = "";
tRequest.Headers.Add(string.Format("Authorization: key={0}", "AA******"));
tRequest.Headers.Add(string.Format("Sender: id={0}", "11********"));
if (DeviceType == 2)
{
var body = new
{
to = deviceToken,
data = new
{
custom_notification = new
{
title = "Notification",
body = message,
sound = "default",
priority = "high",
show_in_foreground = true,
targetScreen = notificationType,//"detail",
},
},
priority = 10
};
json = serializer.Serialize(body);
}
else
{
var body = new
{
to = deviceToken,
content_available = true,
notification = new
{
title = "Notification",
body = message,
sound = "default",
show_in_foreground = true,
},
data = new
{
targetScreen = notificationType,
id = 0,
},
priority = 10
};
json = serializer.Serialize(body);
}
Byte[] byteArray = Encoding.UTF8.GetBytes(json);
tRequest.ContentLength = byteArray.Length;
using (Stream dataStream = tRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse tResponse = tRequest.GetResponse())
{
using (Stream dataStreamResponse = tResponse.GetResponseStream())
{
using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
result.Response = sResponseFromServer;
}
}
}
}
}
catch (Exception ex)
{
result.Successful = false;
result.Response = null;
result.Error = ex;
}
}

I write this code and It's worked for me .
public static string ExcutePushNotification(string title, string msg, string fcmToken, object data)
{
var serverKey = "AAAA*******************";
var senderId = "3333333333333";
var result = "-1";
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://fcm.googleapis.com/fcm/send");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add(string.Format("Authorization: key={0}", serverKey));
httpWebRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
httpWebRequest.Method = "POST";
var payload = new
{
notification = new
{
title = title,
body = msg,
sound = "default"
},
data = new
{
info = data
},
to = fcmToken,
priority = "high",
content_available = true,
};
var serializer = new JavaScriptSerializer();
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = serializer.Serialize(payload);
streamWriter.Write(json);
streamWriter.Flush();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}

I am using this approach and it is working fine:
public class PushNotification
{
private static readonly ILog Logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// firebase
private static Uri FireBasePushNotificationsURL = new Uri("https://fcm.googleapis.com/fcm/send");
private static string ServerKey = ConfigurationManager.AppSettings["FIREBASESERVERKEY"];
public static async Task<bool> SendPushNotification(List<SendNotificationModel> notificationData)
{
try
{
bool sent = false;
foreach (var data in notificationData)
{
var messageInformation = new Message()
{
notification = new Notification()
{
title = data.Title,
text = data.Message,
ClickAction = "FCM_PLUGIN_ACTIVITY"
},
data = data.data,
priority="high",
to =data.DeviceId
};
string jsonMessage = JsonConvert.SerializeObject(messageInformation);
//Create request to Firebase API
var request = new HttpRequestMessage(HttpMethod.Post, FireBasePushNotificationsURL);
request.Headers.TryAddWithoutValidation("Authorization", "key=" + ServerKey);
request.Content = new StringContent(jsonMessage, Encoding.UTF8, "application/json");
HttpResponseMessage result;
using (var client = new HttpClient())
{
result = await client.SendAsync(request);
sent = result.IsSuccessStatusCode;
}
}
return sent;
}
catch(Exception ex)
{
Logger.Error(ex);
return false;
}
}
}

Following Approach, I have used for writing Firebase Notification Service inside ASP.Net REST API.
public async Task<bool> NotifyAsync(string to, string title, string body)
{
try
{
//Server key from FCM console
var serverKey = string.Format("key={0}", "Provide your Server key here from Fibase console");
//Sender id from FCM console
var senderId = string.Format("id={0}", "Provide your Sender Id here from Firebase Console");
var data = new
{
to, // Recipient device token
notification = new { title, body }
};
// Using Newtonsoft.Json
var jsonBody = JsonConvert.SerializeObject(data);
using (var httpRequest = new HttpRequestMessage(HttpMethod.Post, "https://fcm.googleapis.com/fcm/send"))
{
httpRequest.Headers.TryAddWithoutValidation("Authorization", serverKey);
httpRequest.Headers.TryAddWithoutValidation("Sender", senderId);
httpRequest.Content = new StringContent(jsonBody, Encoding.UTF8, "application/json");
using (var httpClient = new HttpClient())
{
var result = await httpClient.SendAsync(httpRequest);
if (result.IsSuccessStatusCode)
{
return true;
}
else
{
// Use result.StatusCode to handle failure
// Your custom error handler here
return false;
}
}
}
}
catch (Exception ex)
{
throw ex;
}
return false;
}

Send file to Trimble Connect (HTTP://connect.trimble.com/)

I will need to send a some file to service (connect.trimble.com).
I do not understand, how upload a file to the service?
I have API instruction:
and I use this code:
string result = string.Empty;
string Url = "https://app.prod.gteam.com/tc/api/2.0/auth";
string TypeContent = "application/json";
string Method = "POST";
object obj = new
{
emailAddress = "MyMail",
key = "MyKey"
};
string Header = string.Empty;
result = RequestPost(Url, TypeContent, Method, Header, obj);
var qwe = result.Split(new char[] { '"' });
Header = "Bearer " + qwe[3];
Url = "https://app.prod.gteam.com/tc/api/2.0/files";
TypeContent = "multipart/form-data";
Method = "POST";
obj = new
{
parentId = "yVWsT_jewHs"
};
result = RequestPost(Url, TypeContent, Method, Header, obj);
private static string RequestPost(string Url, string TypeContent, string Method, string Header, object obj)
{
string result = string.Empty;
var httpWebRequest = (HttpWebRequest)WebRequest.Create(Url);
httpWebRequest.ContentType = TypeContent;
httpWebRequest.Method = Method;
if (!string.IsNullOrEmpty(Header))
{
httpWebRequest.Headers.Add("Authorization", Header);
}
if (obj != null)
{
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = new JavaScriptSerializer().Serialize(obj);
streamWriter.Write(json);
}
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}
This code return error:
The remote server returned an error: (400) Bad Request.

I found answer myself. This topic can be closed.
string Url = "app.prod.gteam.com/tc/api/2.0/files?parentId=bHHkdeBSizA";
bHHkdeBSizA - This ID is parent folder ID, where the file will located, in current API parentId may equals rootId.
public static void UploadFile(string url, string filePath, string Header)
{
using (var client = new WebClient())
{
if (!string.IsNullOrEmpty(Header))
{
client.Headers.Add("Authorization", Header);
}
byte[] result = client.UploadFile(url, filePath);
string responseAsString = Encoding.Default.GetString(result);
}
}

GetDevDefineHeader() will create header and return type is string.

In your url, I do not see the use of encoded query and why are you passing it?
Please check the docs for correct endpoints for CRUD and query operations-
https://developer.intuit.com/docs/api/accounting/JournalEntry
See this example for GET using dev defined-
https://gist.github.com/IntuitDeveloperRelations/0913b4c224de758fde0a
Similarly there is a post example here, you can write similarly for JE-
//string res = CreateV3Customer(consumerKey, consumerSecret, accessToken, accessTokenSecret, realmId);
public string CreateV3Customer(string consumerKey, string consumerSecret, string accessToken, string accessTokenSecret, string realmId)
{
StringBuilder request = new StringBuilder();
StringBuilder response = new StringBuilder();
var requestBody = "{\"FamilyName\":\"Jack\"}";
HttpWebRequest httpWebRequest = WebRequest.Create("https://quickbooks.api.intuit.com/v3/company/"+realmId+"/customer") as HttpWebRequest;
httpWebRequest.Method = "POST";
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add("Authorization", GetDevDefinedOAuthHeader(consumerKey, consumerSecret, accessToken,accessTokenSecret,httpWebRequest, requestBody));
request.Append(requestBody);
UTF8Encoding encoding = new UTF8Encoding();
byte[] content = encoding.GetBytes(request.ToString());
using (var stream = httpWebRequest.GetRequestStream())
{
stream.Write(content, 0, content.Length);
}
HttpWebResponse httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse;
using (Stream data = httpWebResponse.GetResponseStream())
{
string customerr = new StreamReader(data).ReadToEnd();
return customerr;
}
}

Toggl API v8 with .NET

I'm trying to use the new Toggl API (v8) with .NET C#. I've based my code on the example from litemedia (http://litemedia.info/connect-to-toggl-api-with-net), but it was originally created for version 1 of the API.
private const string TogglTasksUrl = "https://www.toggl.com/api/v8/tasks.json";
private const string TogglAuthUrl = "https://www.toggl.com/api/v8/me"; //sessions.json";
private const string AuthenticationType = "Basic";
private const string ApiToken = "user token goes here";
private const string Password = "api_token";
public static void Main(string[] args)
{
CookieContainer container = new CookieContainer();
var authRequest = (HttpWebRequest)HttpWebRequest.Create(TogglAuthUrl);
authRequest.Credentials = CredentialCache.DefaultCredentials;
authRequest.Method = "POST";
authRequest.ContentType = "application/x-www-form-urlencoded";
authRequest.CookieContainer = container;
string value = ApiToken; //= Convert.ToBase64String(Encoding.Unicode.GetBytes(ApiToken));
value = string.Format("{1}:{0}", Password, value);
//value = Convert.ToBase64String(Encoding.Unicode.GetBytes(value));
authRequest.ContentLength = value.Length;
using (StreamWriter writer = new StreamWriter(authRequest.GetRequestStream(), Encoding.ASCII))
{
writer.Write(value);
}
try
{
var authResponse = (HttpWebResponse)authRequest.GetResponse();
using (var reader = new StreamReader(authResponse.GetResponseStream(), Encoding.UTF8))
{
string content = reader.ReadToEnd();
}
HttpWebRequest tasksRequest = (HttpWebRequest)HttpWebRequest.Create(TogglTasksUrl);
tasksRequest.CookieContainer = container;
//var jsonResult = string.Empty;
var tasksResponse = (HttpWebResponse)tasksRequest.GetResponse();
MemoryStream ms = new MemoryStream();
tasksResponse.GetResponseStream().CopyTo(ms);
//using (var reader = new StreamReader(tasksResponse.GetResponseStream(), Encoding.UTF8))
//{
// jsonResult = reader.ReadToEnd();
//}
ms.Seek(0, SeekOrigin.Begin);
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Task));
var tasks = ser.ReadObject(ms) as List<Task>;
ms.Close();
//var tasks = DataContractJsonConvert.DeserializeObject<Task[]>(jsonResult);
foreach (var task in tasks)
{
Console.WriteLine(
"{0} - {1}: {2} starting {3:yyyy-MM-dd HH:mm}",
task.Project.Name,
task.Description,
TimeSpan.FromSeconds(task.Duration),
task.Start);
}
}
catch (System.Exception ex)
{
throw;
}
}
The following line is returning a 404 error.
var authResponse = (HttpWebResponse)authRequest.GetResponse();

Here is code that works. Since I was looking for this answer recently there might still be others as lost as me.
Notes: I used Encoding.Default.GetBytes() because Encoding.Unicode.GetBytes() did not give me a correct result on my .NET string. I hope it doesn't depend on the default setup of Visual Studio.
The content-type is "application/json".
Sorry, I haven't tried a POST version yet.
string ApiToken = "user token goes here";
string url = "https://www.toggl.com/api/v8/me";
string userpass = ApiToken + ":api_token";
string userpassB64 = Convert.ToBase64String(Encoding.Default.GetBytes(userpass.Trim()));
string authHeader = "Basic " + userpassB64;
HttpWebRequest authRequest = (HttpWebRequest)WebRequest.Create(url);
authRequest.Headers.Add("Authorization", authHeader);
authRequest.Method = "GET";
authRequest.ContentType = "application/json";
//authRequest.Credentials = CredentialCache.DefaultNetworkCredentials;
try
{
var response = (HttpWebResponse)authRequest.GetResponse();
string result = null;
using (Stream stream = response.GetResponseStream())
{
StreamReader sr = new StreamReader(stream);
result = sr.ReadToEnd();
sr.Close();
}
if (null != result)
{
System.Diagnostics.Debug.WriteLine(result.ToString());
}
// Get the headers
object headers = response.Headers;
}
catch (Exception e)
{
System.Diagnostics.Debug.WriteLine(e.Message + "\n" + e.ToString());
}
