我正在尝试通过 WebRequest 登录网站。我此时遇到异常:
WebRequest req = WebRequest.Create(formUrl.Trim());
string url,string username,string password
来自文本框。这是完整的代码:
public void LoginToUrl(string url,string username, string password )
{
formUrl = url;
formParams = string.Format("username={0}&password={1}", username,password);
WebRequest req = WebRequest.Create(formUrl.Trim());//
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
bytes = Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
os.Write(bytes, 0, bytes.Length);
}
WebResponse resp = req.GetResponse();
cookieHeader = resp.Headers["Set-cookie"];
}
这是 POST 数据:
