I'm having problems with sending POST request in C# and it seems I misunderstood some HTTP basics. So basically I'm implementing RESTfull service client, which work as follows:
I use WebRequest to make GET requests (with Authorization header) and it's working. But when I use following code to make PUT requests, service is giving "Authentication failed - not logged in" message back:
String url = String.Format("{0}/{1}", AN_SERVER, app);
WebRequest theRequest = WebRequest.Create(url);
theRequest.Method = "POST";
theRequest.ContentType = "text/x-json";
theRequest.ContentLength = json.Length;
Stream requestStream = theRequest.GetRequestStream();
requestStream.Write(Encoding.ASCII.GetBytes(json), 0, json.Length);
requestStream.Close();
theRequest.Headers.Add("Authorization", authToken);
HttpWebResponse response = (HttpWebResponse)theRequest.GetResponse();
I must be making minor mistake (at least I hope so) while sending POST request. So what am I doing wrong?
Thanks.

In the Name field, enter the name of your header rule (for example, My header ). From the Type menu, select Request, and from the Action menu, select Set. In the Destination field, enter the name of the header affected by the selected action. In the Source field, enter where the content for the header comes from.
To send an Axios POST request with headers, you need to use the headers option. With axios. post() , the first parameter is the URL, the 2nd parameter is the request body, and the 3rd parameter is the options . For example, below is how you set the Content-Type header on an HTTP POST request.
Make an HTTP POST Web Request With the HttpWebRequest Class in C# The HttpWebRequest class provides methods to interact directly with the server using HTTP protocol in C#. We can use the HttpWebRequest. Method = "POST" property to specify that an HTTP web request is a POST request in C#.
You can pass duplicate headers as well and there will not be any overwritten of values. For example, If we pass two values of header1 as value1 and value2 then it will be merged and will be passed as header1=value1 and header1=value2. It is the default behaviour.
Moving Headers before the request steam works (as per AI W's comment), because the request stream is adding the body.
The way webrequest is implemented internally, you need to finish the header before writing body, and once its in stream format, its ready to send.
If you look at the implementation of webrequest in reflector or some such decompiling tool, you'll be able to see the logic.
Hope this helps
