I've built my backend in rails. My email address is "[email protected]" and it's already registered. The password is "28902890" here

After giving the following command in terminal 

curl -v -H 'Content-Type: application/json' -H 'Accept: application/json' -X POST https://auth-agdit.herokuapp.com/api/v1/sessions -d "{\"user\":{\"email\":\"sample@zmail\",\"password\":\"28902890\"}}"

I get this response from my backend,

{"success":true,"info":"Logged in :) ","data":{"authentication_token":"iexGFwJ6HwERQZ3wJ4NG"}}

Now I need to get this data from my Android app. I can get json by using WebClient().downloadString() method for simple json where authentication is not needed and the request method is GET.

Now I need to get the output Json for POST method. How can I accomplish that?

There are several methods of doing this. You could use the Xamarin component called RestSharp. This will provide you with easy methods of interfacing with your backend.

var request = new RestRequest("resource/{id}", Method.POST); request.AddParameter("name", "value"); // adds to POST or URL querystring based on Method request.AddUrlSegment("id", 123); // replaces matching token in request.Resource // add parameters for all properties on an object request.AddObject(object); // execute the request RestResponse response = client.Execute(request);

If you do want to simply use the WebClient class provided by the BCL you can use the WebClient.UploadString(string, string) method like so:

using (WebClient client = new WebClient()) { string json = "{\"user\":{\"email\":\"sample@zmail\",\"password\":\"28902890\"}}"; client.UploadString("https://example.com/api/v1/sessions, json); }

If you need more control over the request (such as setting accept headers, etc.) then you can use HttpRequest, see this question for an example of that.

This works but only after I added 'client.Headers[HttpRequestHeader.ContentType] = "application/json";' before UploadString()

This is how I did it:

 WebClient wc = new WebClient(); string baseSiteString = wc.DownloadString("https://auth-agdit.herokuapp.com"); string csrfToken = Regex.Match(baseSiteString, "<meta name=\"csrf-token\" content=\"(.*?)\" />").Groups[1].Value; string cookie = wc.ResponseHeaders[HttpResponseHeader.SetCookie]; Console.WriteLine("CSRF Token: {0}", csrfToken); Console.WriteLine("Cookie: {0}", cookie); wc.Headers.Add(HttpRequestHeader.Cookie, cookie); wc.Headers.Add(HttpRequestHeader.ContentType, "application/json; charset=utf-8"); wc.Headers.Add(HttpRequestHeader.Accept, "application/json, text/javascript, */*; q=0.01"); wc.Headers.Add("X-CSRF-Token", csrfToken); wc.Headers.Add("X-Requested-With", "XMLHttpRequest"); string dataString = @"{""user"":{""email"":""email_here"",""password"":""password_here""}}"; // string dataString = @"{""user"":{""email"":"""+uEmail+@""",""password"":"""+uPassword+@"""}}"; byte[] dataBytes = Encoding.UTF8.GetBytes(dataString); byte[] responseBytes = wc.UploadData(new Uri("https://auth-agdit.herokuapp.com/api/v1/sessions.json"), "POST", dataBytes); string responseString = Encoding.UTF8.GetString(responseBytes); Console.WriteLine(responseString);

Try with this code:

Uri address = new Uri("http://example.com/insert.php"); NameValueCollection nameValueCollection = new NameValueCollection(); nameValueCollection["Name"] = "string-input"; var webClient = new WebClient(); webClient.UploadValuesAsync(address, "POST", nameValueCollection);
