我正在尝试通过 POST 使用 httpwebrequest登录网站（例如： https ://www.facebook.com/login.php?login_attempt=1）。但登录后不返回结果。
我不知道我的代码有什么问题，你能帮我吗？非常感谢！
这是我的代码：
private void Button_Click_1(object sender, RoutedEventArgs e)
{
System.Uri myUri = new System.Uri("https://www.facebook.com/login.php?login_attempt=1");
HttpWebRequest myRequest = (HttpWebRequest)HttpWebRequest.Create(myUri);
myRequest.Method = "POST";
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), myRequest);
}
void GetRequestStreamCallback(IAsyncResult callbackResult)
{
HttpWebRequest myRequest = (HttpWebRequest)callbackResult.AsyncState;
// End the stream request operation
Stream postStream = myRequest.EndGetRequestStream(callbackResult);
StringBuilder postData = new StringBuilder();
postData.Append("email=myEmail");
postData.Append("&password=myPassword");
byte[] byteArray = Encoding.UTF8.GetBytes(postData.ToString());
postStream.Write(byteArray, 0, postData.Length);
postStream.Close();
myRequest.BeginGetResponse(new AsyncCallback(GetResponsetStreamCallback), myRequest);
}
void GetResponsetStreamCallback(IAsyncResult callbackResult)
{
HttpWebRequest request = (HttpWebRequest)callbackResult.AsyncState;
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(callbackResult);
using (StreamReader httpWebStreamReader = new StreamReader(response.GetResponseStream()))
{
string result = httpWebStreamReader.ReadToEnd();
//For debug: show results
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
// something do
});
}
}
