Sending POST parameters via HTTP to a server in C#
Here is a C# Method for sending data to a server via POST.
You would call this method like this:
get_post_response("http://somesite/", "email=email&password=password")
If any of the characters in the params contain special characters (Such as $, #, @) you must call HttpUtility.UrlEncode() on each param or on the entire param string. Here is how you do that: http://www.vcskicks.com/encode-url.php
public static string get_post_response(string page_url, string page_params) {
var request = (HttpWebRequest)HttpWebRequest.Create(page_url);
request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(session);
request.ContentType = "application/x-www-form-urlencoded";
request.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(page_params);
request.ContentLength = bytes.Length;
using (Stream os = request.GetRequestStream()) {
os.Write(bytes, 0, bytes.Length);
}
var resp = request.GetResponse();
CookieContainer cookieJar = new CookieContainer();
session = cookieJar.GetCookies(request.RequestUri);
Stream respStream = resp.GetResponseStream();
byte[] buffer = new byte[1024];
string text = "";
while (Convert.ToBoolean(respStream.Read(buffer, 0, buffer.Length)))
text += Encoding.ASCII.GetString(buffer).Trim('\0');
return text;
}
Enjoy!
