im trying to send POST request using HttpWebRequest and fiddler shows me that im sending GET?
any help will be appreciated since im able to see what im doing wrong.
code :
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(LOGIN_API_BASE_URL);
string postString = string.Format("api_email={0}&api_password={1}", EMAIL, PASSWORD);
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes(postString);
CookieContainer cookies = new CookieContainer();
request.CookieContainer = cookies;
//request.AllowWriteStreamBuffering = true;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
request.Timeout = i_timeout;
//request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1";
//request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
//request.Referer = "https://accounts.craigslist.org";
using (Stream writer = request.GetRequestStream())
{
writer.Write(data, 0, data.Length);
//writer.Close();
}
StreamReader responseReader = new StreamReader(request.GetResponse().GetResponseStream());
string responseData = responseReader.ReadToEnd();
responseReader.Close();
request.GetResponse().Close();
ok found the problem, the url im sending the request to is http://domain.com and when i send it to http://www.domain.com it works and send a post. so new question why is that? ( the answer will get the answer to my question as i dont like the idea of voting my self )

After logged in, cookies are generated for subsequent requests.
I am trying to get cookies by sending a "POST" request.
In the response header, there is a "set-cookies" field and its value is like: "value1=value1,value2=value2......";
However, the CookieContainer i created for the HttpWebRequest is still empty.
So what is happening and how can I have my CookieContainer filled?
Any suggestion would be appreciated.
string loginData = "################################";
CookieContainer cookiecontainer = new CookieContainer();
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("https://www.ftwilliam.com/cgi-bin/Enter.cgi");
myRequest.CookieContainer = cookiecontainer;
myRequest.Method = "POST";
myRequest.KeepAlive = true;
myRequest.AllowAutoRedirect = false;
myRequest.Referer = "https://www.ftwilliam.com/cgi-bin/Enter.cgi";
myRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:26.0) Gecko/20100101 Firefox/26.0";
myRequest.ContentType = "application/x-www-form-urlencoded";
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] loginDataBytes = encoding.GetBytes(loginData);
myRequest.ContentLength = loginDataBytes.Length;
Stream stream = myRequest.GetRequestStream();
stream.Write(loginDataBytes, 0, loginDataBytes.Length);
stream.Close();
HttpWebResponse res = (HttpWebResponse)myRequest.GetResponse();

I have no idea an I am pretty sure not many people are going to want to sift through that much code.
One thing that I see at a glance that may be causing problems is that you are playing with the cookies too much.
Create one CookieContainer and just pass it in with each request.
No need to 'transfer' or 'recreate' the container.
Try looking into google accounts api and GBaseService. I believe you will have to set HOSTED_OR_GOOGLE in accountType as Marty has done here in this post.
I'm trying to use C# to login to hotfile.com. The first big issue was to overcome the 417 Error, which this line solved it:
System.Net.ServicePointManager.Expect100Continue = false;
Now I'm getting this error as I try to login using POST:
You don't seem to accept cookies. Cookies are required in order to log in. Help
I've tried several times, and googled around and I still can't login to Hotfile.com.. My code is this:
string response;
byte[] buffer = Encoding.ASCII.GetBytes("user=XX&pass=XX");
CookieContainer cookies = new CookieContainer();
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create("http://hotfile.com/login.php");
WebReq.Credentials = new NetworkCredential("XX", "XX");
WebReq.PreAuthenticate = true;
WebReq.Pipelined = true;
WebReq.CookieContainer = cookies;
WebReq.KeepAlive = true;
WebReq.Method = "POST";
WebReq.ContentType = "application/x-www-form-urlencoded";
WebReq.ContentLength = buffer.Length;
WebReq.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1)";
Stream PostData = WebReq.GetRequestStream();
PostData.Write(buffer, 0, buffer.Length);
PostData.Close();
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
Stream Answer = WebResp.GetResponseStream();
StreamReader _Answer = new StreamReader(Answer);
response = _Answer.ReadToEnd();
File.WriteAllText("dump.html", response);
Naturally, the user and pass would have your accounts values.
Here's a working example I wrote for you:
var cookies = new CookieContainer();
ServicePointManager.Expect100Continue = false;
var request = (HttpWebRequest)WebRequest.Create("http://www.hotfile.com/login.php");
request.CookieContainer = cookies;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
using (var requestStream = request.GetRequestStream())
using (var writer = new StreamWriter(requestStream))
{
writer.Write("user=XX&pass=XX&returnto=/");
}
using (var responseStream = request.GetResponse().GetResponseStream())
using (var reader = new StreamReader(responseStream))
{
var result = reader.ReadToEnd();
Console.WriteLine(result);
}
After authorisation on www.vkontakte.ru through ie8 me spans on page: www.vkontakte.ru/MyPage. But I cannot receive www.vkontakte.ru/MyPage through a code
HttpWebRequest authRequest = (HttpWebRequest)WebRequest.Create(new Uri("http://vkontakte.ru/login.php", UriKind.Absolute));
authRequest.CookieContainer = new CookieContainer();
authRequest.AllowAutoRedirect = false;
string param = string.Format("email={0}&pass={1}&expire=1", HttpUtility.UrlEncode("---"), HttpUtility.UrlEncode("---"));
authRequest.Method = "POST";
authRequest.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)";
authRequest.ContentType = "application/x-www-form-urlencoded";
authRequest.ContentLength = param.Length;
authRequest.GetRequestStream().Write(Encoding.GetEncoding(1251).GetBytes(param), 0, param.Length);
HttpWebResponse authResponse = (HttpWebResponse)authRequest.GetResponse();
listBox1.Items.Add(authRequest.Address);
Returns http://vkontakte.ru/ instead of www.vkontakte.ru/MyPage =(
HttpContext.Current.Request.Url.AbsoluteUri - can help?
help me!
You forgot to close the request stream.
You should write the following:
using (Stream requestStream = authRequest.GetRequestStream())
using (StreamWriter writer = new StreamWriter(requestStream, Encoding.GetEncoding(1251))
writer.Write(param);
Also, you should run Fiddler check what the request and response look like.
