I am not getting the results that documentation says. I login the Buddy; created application; copy this URL and assign to url string; when I execute the program I am not getting results that are expected (status + Accesstoken) as documentation says. Can anyone please tell me if I am missing something as newbie to http calls. Its running on http requester but not on Poster firefox add-on!
Documentation
http://dev.buddyplatform.com/Home/Docs/Getting%20Started%20-%20REST/HTTP?
Code
string parameters = "{appid:'xxxxxx', appkey: 'xxxxxxx', platform: 'REST Client'}";
private async void SimpleRequest()
{
HttpWebRequest request = null;
HttpWebResponse response = null;
try
{
request = (HttpWebRequest)WebRequest.Create(url);
request.Accept = "application/json";
request.ContentType = "application/json";
request.Method = "POST";
StreamWriter sw = new StreamWriter(await request.GetRequestStreamAsync());
sw.WriteLine(parameters);
sw.Close();
response = (HttpWebResponse) await request.GetResponseAsync();
}
catch (Exception)
{ }
}
Using the HTTP requester add-on on Firefox, I successfully retrieved an access token so their API work.
In C# they provide a line of code to submit your appid and appkey, that might be the problem :
Buddy.Init("yourAppId", "yourAppKey");
My guess is you have to use their .NET SDK!
You can certainly use the REST API from raw REST the way you're doing, though the .NET SDK will handle some of the more complex details of changing service root. I ran your code using my own Buddy credentials and I was able to get JSON containing an Access Token back. You may need to read the response stream back as JSON to retrieve the access token. I used the following code to dump the JSON to the console:
request = (HttpWebRequest)WebRequest.Create(url);
request.Accept = "application/json";
request.ContentType = "application/json";
request.Method = "POST";
StreamWriter sw = new StreamWriter(await request.GetRequestStreamAsync());
sw.WriteLine(parameters);
sw.Close();
response = (HttpWebResponse)await request.GetResponseAsync();
Console.WriteLine(await new StreamReader(response.GetResponseStream()).ReadToEndAsync());
Using Newtonsoft.Json I can parse out my accessToken like this:
Uri url = new Uri("https://api.buddyplatform.com/devices");
request = (HttpWebRequest)WebRequest.Create(url);
request.Accept = "application/json";
request.ContentType = "application/json";
request.Method = "POST";
StreamWriter sw = new StreamWriter(await request.GetRequestStreamAsync());
sw.WriteLine(parameters);
sw.Close();
response = (HttpWebResponse)await request.GetResponseAsync();
var parsed = JsonConvert.DeserializeObject<IDictionary<string,object>>( (await new StreamReader(response.GetResponseStream()).ReadToEndAsync()));
var accessToken = (parsed["result"] as JObject).GetValue("accessToken").ToString();
Console.WriteLine(accessToken);
The 3.0 SDK does all of this for you while exposing the rest of the service through a thin REST wrapper, the migration guide for the 3.0 SDK should help with this.

I am developing a C# application which needs to use the onelogin API to retrieve a session token. I am able to authenticate and and create a token with the following code:
WebRequest Authrequest = WebRequest.Create("https://api.us.onelogin.com/auth/oauth2/token");
Authrequest.Method = "POST";
Authrequest.ContentType = "application/json";
Authrequest.Headers.Add("cache-control", "no-cache");
Authrequest.Headers.Add("Authorization: client_id:XXXXXXX7bbf2c50200d8175206f664dc28ffd3ec66eef0bfedb68c3366420dc, client_secret:XXXXXXXXXX6ba2802187feb23f6450c6812b8e6639361d24aa83f12010f ");
using (var streamWriter = new StreamWriter(Authrequest.GetRequestStream()))
{
string Authjson = new JavaScriptSerializer().Serialize(new
{
grant_type = "client_credentials"
});
streamWriter.Write(Authjson);
}
WebResponse AuthReponse;
AuthReponse = Authrequest.GetResponse();
Stream receiveStream = AuthReponse.GetResponseStream ();
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader (receiveStream);
JObject incdata = JObject.Parse(readStream.ReadToEnd());
string sToken = incdata["data"][0]["access_token"].Value<string>();
AuthReponse.Close();
However, when running the Create Session Login Token with the following code, it only returns a 400 error, and the message has no detail. Just Bad Request:
//Get the session token for the specified user, using the token recieved from previous web request
WebRequest request = WebRequest.Create("https://api.us.onelogin.com/api/1/login/auth");
request.Method = "POST";
request.ContentType = "application/json";
request.Headers.Add("authorization", "bearer:" + sToken);
using (var streamWriter2 = new StreamWriter(request.GetRequestStream()))
{
string json = JsonConvert.SerializeObject(new
{
username_or_email = sUsername,
password = sPassword,
subdomain = "comp-alt-dev"
});
streamWriter2.Write(json);
}
WebResponse response;
response = request.GetResponse();
string streamText = "";
var responseStream = response.GetResponseStream();
using (responseStream)
{
var streamReader = new StreamReader(responseStream);
using (streamReader)
{
streamText = streamReader.ReadToEnd();
streamReader.Close();
//
}
responseStream.Close();
}
Any ideas?
-Thank you
Also for anyone who may be getting this error. in C# the email is case sensitive. I tried User.email.com. In onelogin it was saved as user#email.com. changing the c# to lower case fixed it.
Can you let us know what payload you're sending across the wire to the .../1/login/auth endpoint as well as the response (either as others have suggested as packet snoop, or just as a debug output from the code)
400 means either bad json or the endpoint requires MFA, so this will narrow it down.
~thanks!
Just joining the troubleshooting effort =) -- I can replicate a 400 Bad Request status code with a "bad request" message when the request body contains a username_or_email and/or subdomain value that does not exist, or if the request body is empty.
Can you post what goes over the wire to the OneLogin endpoint...
OK Thanks. So it appears your subdomain does not exist. If you give me an email in the account I can find the correct subdomain value for you.
I'm trying to do a WebRequest to a site from a Windows Phone Application.
But is vry important for me to also get the response from the server.
Here is my code:
Uri requestUri = new Uri(string.Format("http://localhost:8099/hello/{0}", metodo));
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri);
httpWebRequest.ContentType = "application/xml; charset=utf-8";
httpWebRequest.Method = "POST";
using (var stream = await Task.Factory.FromAsync<Stream>(httpWebRequest.BeginGetRequestStream,
httpWebRequest.EndGetRequestStream, null))
{
string xml = "<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">Ahri</string>";
byte[] xmlAsBytes = Encoding.UTF8.GetBytes(xml);
await stream.WriteAsync(xmlAsBytes, 0, xmlAsBytes.Length);
}
Unfortunatelly, I have no idea of how I could get the response from the server.
Does anyone have an idea?
Thanks in advance.
Thanks to #max I found the solution and wanted to share it above.
Here is how my code looks like:
string xml = "<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">Claor</string>";
Uri requestUri = new Uri(string.Format("http://localhost:8099/hello/{0}", metodo));
string responseFromServer = "no response";
HttpWebRequest httpWebRequest = HttpWebRequest.Create(requestUri) as HttpWebRequest;
httpWebRequest.ContentType = "application/xml; charset=utf-8";
httpWebRequest.Method = "POST";
using (Stream requestStream = await httpWebRequest.GetRequestStreamAsync())
{
byte[] xmlAsBytes = Encoding.UTF8.GetBytes(xml);
await requestStream.WriteAsync(xmlAsBytes, 0, xmlAsBytes.Length);
}
WebResponse webResponse = await httpWebRequest.GetResponseAsync();
using (var reader = new StreamReader(webResponse.GetResponseStream()))
{
responseFromServer = reader.ReadToEnd();
}
I hope it will help someone in the future.
This is very common question for people new in windows phone app
development. There are several sites which gives tutorials for the
same but I would want to give small answer here.
In windows phone 8 xaml/runtime you can do it by using HttpWebRequest or a WebClient.
Basically WebClient is a wraper around HttpWebRequest.
If you have a small request to make then user HttpWebRequest. It goes like this
HttpWebRequest request = HttpWebRequest.Create(requestURI) as HttpWebRequest;
WebResponse response = await request.GetResponseAsync();
using (var reader = new StreamReader(response.GetResponseStream()))
{
string responseContent = reader.ReadToEnd();
// Do anything with you content. Convert it to xml, json or anything.
}
Although this is a get request and i see that you want to do a post request, you have to modify a few steps to achieve that.
Visit this place for post request.

I am trying to retrieve an order from the Eventbrite API. I have a valid OAuth token and order number. I have verified this by using postman which successfully returns the correct JSON.
However when I make the call using the following c# code, I get a 401 Unauthorised:
var client = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Get, "https://www.eventbriteapi.com/v3/orders/{orderNo}");
req.Headers.Add("Authorization", "Bearer {authToken}");
var response = await client.SendAsync(req);
I've tried replacing the header with:
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("{authToken}");
I have also tried:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.eventbriteapi.com/v3/orders/{orderNo}");
request.Headers.Add("Authorization", "Bearer {authToken}");
request.Accept = "application/json";
using(WebResponse response = request.GetResponse())
{
using(Stream dataStream = response.GetResponseStream())
{
using(StreamReader reader = new StreamReader(dataStream))
{
string responseFromServer = reader.ReadToEnd();
}
}
}
All of these get a 401 response.
I know the authtoken and the eventid are correct, so there must be something wrong with my code.
Am I doing something wrong with the authroisation token?
Have you tried ?token={authToken} option on the EventBrite API?
This would at least confirm if it's a problem with the way the header is being sent across.
http://developer.eventbrite.com/docs/auth/
You omitted the trailing '/' in the URL, which caused a subsequent redirect from "eventbriteapi.com/v3/orders/{orderNo}" to "eventbriteapi.com/v3/orders/{orderNo}/". The authorization header was dropped in the redirect.
I fetch webpages in order to feed data to my application. However, the pages contain a lot of images which I don't require at all. I only need the text data.
My problem is that the web requests take an unacceptable amount of time. I think the images also are fetch during a web request. Is there any way to eliminate the images and download only the text data?
The following is the code that I am using currently.
var httpWebRequest = HttpWebRequest.Create(url) as HttpWebRequest;
httpWebRequest.Method = "GET";
httpWebRequest.ProtocolVersion = HttpVersion.Version11;
httpWebRequest.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate");
httpWebRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
httpWebRequest.Proxy = null;
httpWebRequest.KeepAlive = true;
httpWebRequest.Accept = "text/html";
string responseString = null;
var httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse;
using (var responseStream = httpWebResponse.GetResponseStream())
{
using (var streamReader = new StreamReader(responseStream))
{
responseString = streamReader.ReadToEnd();
}
}
Also, any other optimization suggestions are most welcome.
That is incorrect.
HttpWebRequest does not know anything about HTML or images; it just sends raw HTTP requests.
You can use Fiddler to see exactly what's going on.

How to upload video on Dailymotion with c# ?? Is somebody has a complete code?
When I tried every thing but publishing is not working. I used fiddler but I cant find the error.
Here is the code
var request = WebRequest.Create("https://api.dailymotion.com/me/videos?url=" + Uri.EscapeUriString(uploadResponse.url));
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.Headers.Add("Authorization", "OAuth " + accessToken);
var requestBytes = Encoding.UTF8.GetBytes("title=test 123&channel=Funny&tags=Humor&description=Testing testing&published=true");
var requestBytes = Encoding.UTF8.GetBytes(requestString);
var requestStream = request.GetRequestStream();
requestStream.Write(requestBytes, 0, requestBytes.Length);
var response = request.GetResponse();
var responseStream = response.GetResponseStream();
string responseString;
using (var reader = new StreamReader(responseStream))
{
responseString = reader.ReadToEnd();
}
When it reaches request.GetResponse() it gives the error. So what is the problem here..?
I believe you need to get rid of the "me" in the url as you're using OAuth instead of basic authentication, like this:
"https://api.dailymotion.com/videos?url="
Instead of:
"https://api.dailymotion.com/me/videos?url="
At least in a quick scan that looks like it's it, I wrote an auto-publisher for a client a year ago and it didn't use the me in the url. My credentials are invalid now, so can't test it unfortunately. It seems to be a bug in the answer you linked.
If you can read other languages, I found it helpful just going through their SDKs and converting the code:
