试图在C＃中发送使用帖子的用户名/密码 [英] Trying to send username/password useing post in C#

问题描述

我正在尝试使用WebRequest或WebClient登录网站，但似乎不太顺利。

其中一个原因可能是因为我不太了解它的逻辑。

无论如何这里是我目前使用的代码任何帮助都非常感谢。



< pre lang =c＃> private void button2_Click（ object sender，EventArgs e）
{
string URLAuth = http://www.lyndatobin-howes.com/wp-login.php;
WebClient webClient = new WebClient（）;
NameValueCollection formData = new NameValueCollection（）;
formData [ log] = xxxx;
formData [ pwd] = xxxx;
formData [ wp-submit] = 登录;
formData [ redirect_to] = http://www.lyndatobin-howes.com/wp-login.php;
formData [ testcookie] = 1;
byte [] responseBytes = webClient.UploadValues（URLAuth， POST，formData）;
string resultAuthTicket = Encoding.UTF8.GetString（responseBytes）;
webClient.Dispose（）;

// string searchammount = comboBox1.SelectedItem.ToString（）;
WebRequest Logingrequest = WebRequest.Create（ http://www.lyndatobin-howes.com/wp-login .PHP）;
Logingrequest.Credentials = CredentialCache.DefaultCredentials;
Logingrequest.ContentType = application / x-www-form-urlencoded;
Logingrequest.Method = POST;
WebResponse response = Logingrequest.GetResponse（）;
流dataStream = response.GetResponseStream（）;
// 使用StreamReader打开流以便于访问。
StreamReader阅读器= new StreamReader（dataStream）;
// 阅读内容。
string responseFromServer = reader.ReadToEnd（）;
richTextBox2.Text = responseFromServer;

reader.Close（）;
dataStream.Close（）;
response.Close（）;
}

或尝试这种方式..

  public   static   void  PostString（ string 地址）
 {
  string  data =  时间=上午12:00温度= 50; 
  string  method =   POST; 
 WebClient client =  new  WebClient（）; 
  string  reply = client.UploadString（address，method，data）; 
 
 Console.WriteLine（回复）; 
}

我尝试了一种不同的方式：

任何帮助都会非常感激。

 WebRequest Logingrequest = WebRequest.Create（  http：//www.lyndatobin- howes.com/wp-login.php）; 
 Logingrequest.Credentials = CredentialCache.DefaultCredentials; 
 Logingrequest.ContentType =   application / x-www-form-urlencoded; 
 Logingrequest.Method =   POST; 
  string  postData =   log = admin& pwd = m7625zsw& wp-submit =登录& redirect_to = http：//www.lyndatobin-howes.com/wp-login.php& testcookie = 1; 
  byte  [] byteArray = Encoding.UTF8.GetBytes（postData）; 
  //  设置WebRequest的ContentLength属性。 
 Logingrequest.ContentLength = byteArray.Length; 
流dataStream = Logingrequest.GetRequestStream（）; 
 dataStream.Write（byteArray， 0 ，byteArray.Length）; 
 WebResponse response = Logingrequest.GetResponse（）; 
 dataStream = response.GetResponseStream（）; 
  //  使用StreamReader打开流以便于访问。 
 StreamReader阅读器=  new  StreamReader（dataStream）; 
  //  阅读内容。 
  string  responseFromServer = reader.ReadToEnd（）; 
 richTextBox2.Text = responseFromServer; 
 
 reader.Close（）; 
 dataStream.Close（）; 
 response.Close（）; 

I am trying to "log in a website using WebRequest or WebClient, and doesn't seem to go very well.
One of the reasons is probably because i don't understand the logic of it well enough.
Anyway here is the code i currently use Any help is highly appreciated.

private void button2_Click(object sender, EventArgs e)
        {
            string URLAuth = "http://www.lyndatobin-howes.com/wp-login.php";
            WebClient webClient = new WebClient();
            NameValueCollection formData = new NameValueCollection();
            formData["log"] = "xxxx";
            formData["pwd"] = "xxxx";
            formData["wp-submit"] = "Log In";
            formData["redirect_to"] = "http://www.lyndatobin-howes.com/wp-login.php";
            formData["testcookie"] = "1";
            byte[] responseBytes = webClient.UploadValues(URLAuth, "POST", formData);
            string resultAuthTicket = Encoding.UTF8.GetString(responseBytes);
            webClient.Dispose();

            //string searchammount = comboBox1.SelectedItem.ToString();
            WebRequest Logingrequest = WebRequest.Create("http://www.lyndatobin-howes.com/wp-login.php");
            Logingrequest.Credentials = CredentialCache.DefaultCredentials;
            Logingrequest.ContentType = "application/x-www-form-urlencoded";
            Logingrequest.Method = "POST";
            WebResponse response = Logingrequest.GetResponse();
            Stream dataStream = response.GetResponseStream();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader(dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd();
            richTextBox2.Text = responseFromServer;

            reader.Close();
            dataStream.Close();
            response.Close();
        }

I've tried a different way still nothing:
any help will be extremely appreciated.

WebRequest Logingrequest = WebRequest.Create("http://www.lyndatobin-howes.com/wp-login.php");
            Logingrequest.Credentials = CredentialCache.DefaultCredentials;
            Logingrequest.ContentType = "application/x-www-form-urlencoded";
            Logingrequest.Method = "POST";
            string postData = "log=admin&pwd=m7625zsw&wp-submit=Log In&redirect_to=http://www.lyndatobin-howes.com/wp-login.php&testcookie=1";
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);
            // Set the ContentLength property of the WebRequest.
            Logingrequest.ContentLength = byteArray.Length;
            Stream dataStream = Logingrequest.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            WebResponse response = Logingrequest.GetResponse();
            dataStream = response.GetResponseStream();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader(dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd();
            richTextBox2.Text = responseFromServer;

            reader.Close();
            dataStream.Close();
            response.Close();
