HTTP Post request with custom header
42,680
Solution 1
Use WebRequest.ContentType property. Some headers can be set using API properties only.
EDIT:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.androidlost.com/androidlost/greet");
request.ContentType = "text/x-gwt-rpc; charset=utf-8";
Solution 2
According to the MSDN documentation, HttpWebRequest.Header Property.
The Content-Type are modified using the ContentType
property.
This requires that you cast the WebRequest
to HttpWebRequest
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.androidlost.com/androidlost/greet");

I want to make a HTTP Post request from C#. This request has a custom headers. When I try to start my program I received this exception:
Italian:
Questa intestazione deve essere modificata utilizzando la proprietà o il metodo appropriato. Nome parametro: name
English:
This header must be modified using the appropriate property or method.
On line:
request.Headers.Add("Content-Type", "text/x-gwt-rpc; charset=utf-8");
This is my code:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net; using System.Collections.Specialized; using System.IO; using System.Text.RegularExpressions; using System.Dynamic; using System.Collections; using System.Collections.ObjectModel; using System.Net.Security; using System.Web; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { WebRequest request = WebRequest.Create("http://www.androidlost.com/androidlost/greet"); request.Method = "POST"; request.Headers.Add("Content-Type", "text/x-gwt-rpc; charset=utf-8"); string postData = "Test"; byte[] byteArray = Encoding.UTF8.GetBytes(postData); request.ContentLength = byteArray.Length; Stream dataStream = request.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); } } }
