代码工作正常但我仍然无法登录 IRCTC 网站
Code Works Fine But I am still not able to login into IRCTC Website
一切正常,但我们点击 submitData()
按钮,我将显示登录页面而不是 我的主页、
所以首先我导航登录页面它会设置 cookie,然后存储在 cookie 容器代码中的 cookie 是
CookieContainer cookieJar = new CookieContainer();
public Form1()
{
String captcha;
InitializeComponent();
}
private void BUTTON_LOGIN_Click(object sender, EventArgs e)
{
//Get captcha
var request = (HttpWebRequest)HttpWebRequest.Create("https://www.irctc.co.in/eticketing/loginHome.jsf");
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
request.KeepAlive = true;
request.CookieContainer = cookieJar;
request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36";
var response = request.GetResponse();
using (var stream = response.GetResponseStream())
{
}
// need array, different storage for every cookies
//
foreach (Cookie c in cookieJar.GetCookies(response.ResponseUri))
{
request.CookieContainer.Add(c);
MessageBox.Show("Cookie['" + c.Name + "']: " + c.Value);
}
}
然后我使用 cookie 请求验证码
private void pictureBox1_Click(object sender, EventArgs e) // This Event Refresh thr captcha
{
//Get captch
var request =(HttpWebRequest)HttpWebRequest.Create("https://www.irctc.co.in/eticketing/captchaImage");
request.Accept = "image/webp,image/*,*/*;q=0.8";
WebHeaderCollection myWebHeaderCollection = request.Headers;
myWebHeaderCollection.Add("Accept-Language", "en-US;q=0.8");
myWebHeaderCollection.Add("Upgrade-Insecure-Requests", "1");
request.KeepAlive = true;
Uri target = new Uri("https://www.irctc.co.in");
cookieJar.Add(new Cookie("language", "en_IN") { Domain = target.Host });
request.CookieContainer = cookieJar;
request.Referer = "https://www.irctc.co.in/eticketing/loginHome.jsf";
request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36";
var response = request.GetResponse();
using (var stream = response.GetResponseStream())
{
pictureBox1.Image = Bitmap.FromStream(stream);
}
// need array, different storage for every cookies
//
foreach (Cookie c in cookieJar.GetCookies(response.ResponseUri))
{
request.CookieContainer.Add(c);
MessageBox.Show("Cookie['" + c.Name + "']: " + c.Value);
}
}
private void button1_Click(object sender, EventArgs e)
{
submitData();
}
private void displayHtml(String html)
{
webBrowser1.Navigate("about:blank");
while (webBrowser1.Document == null || webBrowser1.Document.Body == null)
Application.DoEvents();
webBrowser1.Document.OpenNew(true).Write(html);
}
最后,我在将验证码填入文本框后提交了数据,这是错误这是再次重定向我的登录页面,这是怎么回事。
private void submitData()
{
try
{
String user = "myusername";
String pass = "mypassword";
String submit = "Submit";
String captcha=richTextBox1.Text.ToString() ;
ASCIIEncoding encoding = new ASCIIEncoding();
// MessageBox.Show(captcha);
string postData = "j_username=" + user + "&j_password=" + pass + "&j_captcha=" + captcha + "&submit=" + submit + "&tneg=" ;
byte[] data = Encoding.UTF8.GetBytes(postData);
Uri target = new Uri("https://www.irctc.co.in");
cookieJar.Add(new Cookie("language", "en_IN"){ Domain = target.Host });
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("https://www.irctc.co.in/eticketing/home");
request.CookieContainer = cookieJar;
WebHeaderCollection myWebHeaderCollection = request.Headers;
myWebHeaderCollection.Add("Accept-Language", "en-US;q=0.8");
myWebHeaderCollection.Add("Upgrade-Insecure-Requests", "1");
request.Method = "POST";
request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36";
request.ContentType = "application/x-www-form-urlencode";
request.Referer = "https://www.irctc.co.in/eticketing/loginHome.jsf";
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
request.ServicePoint.Expect100Continue = false;
// var bytes = Encoding.UTF8.GetBytes("action=login&from=http%3A%2F%2Fwww.dofus.com%2Ffr&login=user123&password=password1232F&remember=1");
// request.ContentLength = bytes.Length;
request.ContentLength = data.Length;
request.KeepAlive = true;
// request.AutomaticDecompression = DecompressionMethods.GZip;
// request.AutomaticDecompression = DecompressionMethods.Deflate;
// request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate, br");
// request.SendChunked = true;
// request.TransferEncoding = "gzip, deflate, br";
request.Host = "www.irctc.co.in";
//request.Headers.Add
Stream stream = request.GetRequestStream();
stream.Write(data, 0, data.Length);
stream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
stream = response.GetResponseStream();
foreach (Cookie c in cookieJar.GetCookies(request.RequestUri))
{
MessageBox.Show("Cookie['" + c.Name + "']: " + c.Value);
}
StreamReader sr = new StreamReader(stream);
//richTextBox1.Text = sr.ReadToEnd();
String myhtml = sr.ReadToEnd().ToString();
displayHtml(myhtml);
sr.Close();
stream.Close();
}
catch (Exception ex)
{
MessageBox.Show("Error : " + ex.Message);
}
}
方法submitData()中
request.ContentType = "application/x-www-form-urlencode"
这里打错了,你漏了一个'd'
应该是这样的:-
request.ContentType = "application/x-www-form-urlencoded"
ContentType 是 "application/x-www-form-urlencoded"。
如果服务器无法理解表单数据类型(在这种情况下 "application/x-www-form-urlencode" 对服务器来说是未知的),那么它将拒绝请求并将用户重定向到您提到的登录页面。
您还可以查看 Form ContentType in HTML Forms(w3.org) 了解更多信息。
希望这对您有所帮助:)
