Second time doing a Web Request doesn't work

I have been trying to do some http requests in C#. First time doing http request GET it worked, but the second time it didn't work and it returned null, can someone please help?
private static dynamic WebRequestGET(Uri url)
{
try
{
var request = WebRequest.Create(url);
request.Method = "GET";
request.Timeout = 10000;
WebResponse webResponse = request.GetResponse();
var webStream = webResponse.GetResponseStream();
var reader = new StreamReader(webStream);
var data = reader.ReadToEnd();
dynamic jsonData = JObject.Parse(data);
request.Abort();
webResponse.Close();
webStream.Close();
return jsonData;
}
catch(Exception e)
{
var window = GetConsoleWindow();
ShowWindow(window, 1);
Console.WriteLine($"Error occured while fetching data, if error will occur again please create issue on github{Environment.NewLine}{e.Message}");
Console.ReadKey();
Application.Exit();
return null;
}
}

Try using this to make the get request. You might need to add restsharp using nuget.
using RestSharp;
// ^^ put at top of file
var client = new RestClient("https://www.google.com");
var request = new RestRequest();
request.Method = Method.Get;
RestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
// change this to whatever you want ^^
I'd also recommend postman.com since it can generate the code for you.

Is there any possibility to send post with body using OAuth 1.0?

i am trying to send a POST request with body to WordPress API. I am still getting 401 error.
I decided to use: https://gist.github.com/DeskSupport/2951522 to authorize via OAuth 1.0 and it works perfectly with GET method. Then i wanted to implement another method which sends simple body.
That's my code:
var oauth = new OAuth.Manager();
oauth["consumer_key"] = _consumerKey;
oauth["consumer_secret"] = _consumerSecret;
oauth["token"] = _accessToken;
oauth["token_secret"] = _tokenSecret;
var appUrl = _baseUrl + url;
var authzHeader = oauth.GenerateAuthzHeader(appUrl, "POST");
string body = GenerateBody(parameters);
byte[] encodedData = Encoding.ASCII.GetBytes(body);
var request = (HttpWebRequest)WebRequest.Create(appUrl);
request.Method = "POST";
request.PreAuthenticate = true;
request.AllowWriteStreamBuffering = true;
request.Headers.Add("Authorization", authzHeader);
request.ContentLength = encodedData.Length;
request.ContentType = "application/x-www-form-urlencoded";
Stream newStream = request.GetRequestStream();
newStream.Write(encodedData, 0, encodedData.Length);
using (var response = (HttpWebResponse)request.GetResponse())
{
if (response.StatusCode != HttpStatusCode.OK)
{
}
}
The result of method GenerateBody is user_login=login&user_pass=BXE&04K44DoR1*a
I also tried to change the '&' character to '%26' but it didn't work.
This request works via Postman and i don;t know what's wrong.

OK, I found a solution.
https://blog.dantup.com/2016/07/simplest-csharp-code-to-post-a-tweet-using-oauth/
This guy wrote the way to make this request. What is also important you have to change a oauth_nonce for unique token.

C# Credential validation against Jira using the REST API

I'm working on a C# Windows Form application and I would like to have the ability to test a users' credentials against Jira. Basically the user would input their username and password, click OK and the program will tell them if their credentials are accepted or not.
I already have working code (see below) that uses basic authentication via HttpWebRequest to create new tickets (aka issues), close tickets, add watchers, etc - so I figured this would be easy but I'm struggling with it.
As an analog, you can do a credentials check against Active Directory very easily using the System.DirectoryServices.AccountManagement namespace. Basically the method authenticateAD() will simply return true or false:
private bool authenticateAD(string username, string password)
{
PrincipalContext pc = new PrincipalContext(ContextType.Domain, "example.com");
bool isValid = pc.ValidateCredentials(username,password);
return isValid;
}
This is exactly the kind of thing I want to do with Jira.
For reference, here's the code I'm using to add/close/update tickets in jira - maybe it can be modified to do what I want?
private Dictionary<string, string> sendHTTPtoREST(string json, string restURL)
{
HttpWebRequest request = WebRequest.Create(restURL) as HttpWebRequest;
request.Method = "POST";
request.Accept = "application/json";
request.ContentType = "application/json";
string mergedCreds = string.Format("{0}:{1}", username, password);
byte[] byteCreds = UTF8Encoding.UTF8.GetBytes(mergedCreds);
request.Headers.Add("Authorization", "Basic " + byteCreds);
byte[] data = Encoding.UTF8.GetBytes(json);
try
{
using (var requestStream = request.GetRequestStream())
{
requestStream.Write(data, 0, data.Length);
requestStream.Close();
}
}
catch(Exception ex)
{
displayMessages(string.Format("Error creating Jira: {0}",ex.Message.ToString()), "red", "white");
Dictionary<string, string> excepHTTP = new Dictionary<string, string>();
excepHTTP.Add("error", ex.Message.ToString());
return excepHTTP;
}
response = (HttpWebResponse)request.GetResponse();
var reader = new StreamReader(response.GetResponseStream());
string str = reader.ReadToEnd();
var jss = new System.Web.Script.Serialization.JavaScriptSerializer();
var sData = jss.Deserialize<Dictionary<string, string>>(str);
if(response.StatusCode.ToString()=="NoContent")
{
sData.Add("code", "NoContent");
request.Abort();
return sData;
}
else
{
sData.Add("code", response.StatusCode.ToString());
request.Abort();
return sData;
}
}
Thanks!

How about attempting to access the root page of JIRA and see if you get an HTTP 403 error?
try
{
// access JIRA using (parts of) your existing code
}
catch (WebException we)
{
var response = we.Response as HttpWebResponse;
if (response != null && response.StatusCode == HttpStatusCode.Forbidden)
{
// JIRA doesn't like your credentials
}
}

The HttpClient would be simple and best to use check credentials with GetAsync.
The sample code is below
using (HttpClient client = new HttpClient())
{
client.BaseAddress = new Uri(JiraPath);
// Add an Accept header for JSON format.
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
string mergedCreds = string.Format("{0}:{1}", username, password);
byte[] byteCreds = UTF8Encoding.UTF8.GetBytes(mergedCreds);
var authHeader = new AuthenticationHeaderValue("Basic", byteCreds);
client.DefaultRequestHeaders.Authorization = authHeader;
HttpResponseMessage response = client.GetAsync(restURL).Result; // Blocking call!
if (response.IsSuccessStatusCode)
{
strJSON = response.Content.ReadAsStringAsync().Result;
if (!string.IsNullOrEmpty(strJSON))
return strJSON;
}
else
{
exceptionOccured = true;
// Use "response.ReasonPhrase" to return error message
}
}

Unauthorized error when trying to get Nest Access Token

Everything was working fine until a couple days ago, I started getting an Unauthorized error when trying to get a Nest Access Token. I've double checked and the client ID and client secret code are all correct. Any ideas on what could be causing it?
HttpWebRequest request = WebRequest.CreateHttp("https://api.home.nest.com/oauth2/access_token?");
var token = await request.GetValueFromRequest<NestToken>(string.Format(
"client_id={0}&code={1}&client_secret={2}&grant_type=authorization_code",
CLIENTID,
code.Value,
CLIENTSECRET));
public async static Task<T> GetValueFromRequest<T>(this HttpWebRequest request, string postData = null)
{
T returnValue = default(T);
if (!string.IsNullOrEmpty(postData))
{
byte[] requestBytes = Encoding.UTF8.GetBytes(postData);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
using (var postStream = await request.GetRequestStreamAsync())
{
await postStream.WriteAsync(requestBytes, 0, requestBytes.Length);
}
}
else
{
request.Method = "GET";
}
var response = await request.GetResponseAsync();
if (response != null)
{
using (var receiveStream = response.GetResponseStream())
{
using (var reader = new StreamReader(receiveStream))
{
var json = await reader.ReadToEndAsync();
var serializer = new DataContractJsonSerializer(typeof(T));
using (var tempStream = new MemoryStream(Encoding.UTF8.GetBytes(json)))
{
return (T)serializer.ReadObject(tempStream);
}
}
}
}
return returnValue;
}

While I can't provide an answer I can confirm the same thing is happening to my iOS app in the same timeframe.
Taking my url and post values works fine using postman in chrome. Alamofire is throwing up error 401, as is native swift test code like yours.
Have Nest perhaps changed their https negotiation?

This turned out to be because of a fault on Nest's end which was later fixed.

Box API Create Shared link

I am trying to upload some documents to Box and create and retrieve a shared link for each of them.
This is the code I am using for it, but I always retrieve 403:access_denied_insufficient_permissions.
Any idea of why this is happening?
Hope you can help me! Thanks.
// CREATE THE FILE
BoxFileRequest req = new BoxFileRequest
{
Name = zipFile.Name,
Parent = new BoxRequestEntity { Id = newFolder.Id}
};
BoxFile uploadedFile = client.FilesManager.UploadAsync(req, stream).Result;
//REQUEST SHARED LINK
BoxSharedLinkRequest sharedLinkReq = new BoxSharedLinkRequest()
{
Access = BoxSharedLinkAccessType.open,
Permissions = new BoxPermissionsRequest
{
Download = BoxPermissionType.Open,
Preview = BoxPermissionType.Open,
}
};
BoxFile fileLink = fileManager.CreateSharedLinkAsync(uploadedFile.Id, sharedLinkReq).Result;

you need to give the access token and url. I have use the Following code and in JSON Format you will get the Response. For more reference check the box API document
HttpWebRequest httpWReq = HttpWebRequest)WebRequest.Create("https://api.box.com/2.0/folders/" + FolderID);
ASCIIEncoding encoding = new ASCIIEncoding();
string putData = "{\"shared_link\": {\"access\": \"open\"}}";
byte[] data = encoding.GetBytes(putData);
httpWReq.Method = "PUT";
httpWReq.Headers.Add("Authorization", "Bearer ");
httpWReq.ContentType = "application/json";
httpWReq.ContentLength = data.Length;
Use the httpwebrequest PUT method after this.
Mark it as Answer if its helpful.

It looks as if you are using the 3rd party BoxSync V2 API object. If you would like to just code to the API directly I had a similar issue that you are having. If you view this post you will see the answer. Here is the code I use and it works.
string uri = String.Format(UriFiles, fileId);
string response = string.Empty;
string body = "{\"shared_link\": {\"access\": \"open\"}}";
byte[] postArray = Encoding.ASCII.GetBytes(body);
try
{
using (var client = new WebClient())
{
client.Headers.Add("Authorization: Bearer " + token);
client.Headers.Add("Content-Type", "application/json");
response = client.UploadString(uri, "PUT", body);
}
}
catch (Exception ex)
{
return null;
}
return response;
