Đăng nhập vào trang web qua C#

Question

Tôi đã thử mọi thứ tôi có thể tìm thấy trên web về cách thực hiện điều này để đăng nhập vào trang web này. Đây là thất bại gần đây nhất.

// I have tried with multiple different URLS this one 
// and http://www.movable.com/login do not throw errors 
string url = "http://portal.movable.com/"; 
string username = "<myusername>"; 
string password = "<mypassword>"; 
string authTok = @"+HOt3NTkkIAHkMSMvzQisEquhun9xvIG1mHzIEh6CAo="; 
string postData = "utf8=✓" + "&authenticity_token=" + authTok + 
     "&user[login]=" + username + 
     "&user[password]=" + password + "&user[offset]=-5"; 

var container = new CookieContainer(); 
var buffer = Encoding.UTF8.GetBytes(postData); 

var request = (HttpWebRequest)HttpWebRequest.Create(url); 
request.CookieContainer = container; 
request.UserAgent = "Mozilla/5.0"; 
request.Method = "POST"; 
request.KeepAlive = true; 
request.AllowAutoRedirect = true; 
request.CookieContainer = container; 
request.ContentLength = buffer.Length; 
request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8"; 
request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; 

using (var requestStream = request.GetRequestStream()) 
    requestStream.Write(buffer, 0, buffer.Length); 

using (var response = request.GetResponse()) 
{ 

     using (var reader = new StreamReader(response.GetResponseStream())) 
     { 
      var result = reader.ReadToEnd(); 
      //this is to read the page source after the request 
      MessageBox.Show(result); 
     }    
} 

Ngoài ra ở đây là liệu có liên quan từ trang web (Tôi biết các mã khác nhau trong ví dụ tôi đã làm cho họ giống nhau và nó không làm việc)

<form accept-charset="UTF-8" action="/signin" class="new_user" id="new_user" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="authenticity_token" type="hidden" value="hHfoUnIbi+6RB51x1cqXqAYHkjz9mCi7nc86gMdiMOo=" /></div> 

    <p class="notice">Signed out successfully.</p> 

    <h2>login to your account</h2> 

    <label for="user_login">Login</label> 
    <input id="user_login" name="user[login]" size="30" type="text" /> 
    <label for="user_password">Password</label> 
    <input id="user_password" name="user[password]" size="30" type="password" /> 

    <input id="user_offset" name="user[offset]" type="hidden" /> 


    <label for="user_remember_me"> 
    <input name="user[remember_me]" type="hidden" value="0" /><input id="user_remember_me" name="user[remember_me]" type="checkbox" value="1" /> 
    Remember me on this computer. 
    </label> 
    <button class="login" name="button" type="submit">Login</button> 
    <a href="https://stackoverflow.com/users/password/new" class="forgotPassword">Forgot password?</a> 
    </form> </div>

Hãy thử cách này:

 var cookieJar = new CookieContainer(); 
     CookieAwareWebClient client = new CookieAwareWebClient(cookieJar); 

     // the website sets some cookie that is needed for login, and as well the 'authenticity_token' is always different 
     string response = client.DownloadString("http://portal.movable.com/signin"); 

     // parse the 'authenticity_token' and cookie is auto handled by the cookieContainer 
     string token = Regex.Match(response, "authenticity_token.+?value=\"(.+?)\"").Groups[1].Value; 
     string postData = 
      string.Format("utf8=%E2%9C%93&authenticity_token={0}&user%5Blogin%5D=USERNAME&user%5Bpassword%5D=PASSWORD&user%5Boffset%5D=5.5&user%5Bremember_me%5D=0&button=", token); 


     //WebClient.UploadValues is equivalent of Http url-encode type post 
     client.Method = "POST"; 
     response = client.UploadString("http://portal.movable.com/signin", postData); 


     //i am getting invalid user/pass, but i am sure it will work fine with normal user/password 

    } 

hảo hạng sử dụng:

public class CookieAwareWebClient : WebClient 
{ 
    public string Method; 
    public CookieContainer CookieContainer { get; set; } 
    public Uri Uri { get; set; } 

    public CookieAwareWebClient() 
     : this(new CookieContainer()) 
    { 
    } 

    public CookieAwareWebClient(CookieContainer cookies) 
    { 
     this.CookieContainer = cookies; 
    } 

    protected override WebRequest GetWebRequest(Uri address) 
    { 
     WebRequest request = base.GetWebRequest(address); 
     if (request is HttpWebRequest) 
     { 
      (request as HttpWebRequest).CookieContainer = this.CookieContainer; 
      (request as HttpWebRequest).ServicePoint.Expect100Continue = false; 
      (request as HttpWebRequest).UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0"; 
      (request as HttpWebRequest).Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; 
      (request as HttpWebRequest).Headers.Add(HttpRequestHeader.AcceptLanguage, "en-US,en;q=0.5"); 
      (request as HttpWebRequest).Referer = "http://portal.movable.com/signin"; 
      (request as HttpWebRequest).KeepAlive = true; 
      (request as HttpWebRequest).AutomaticDecompression = DecompressionMethods.Deflate | 
                   DecompressionMethods.GZip; 
      if (Method == "POST") 
      { 
       (request as HttpWebRequest).ContentType = "application/x-www-form-urlencoded"; 
      } 

     } 
     HttpWebRequest httpRequest = (HttpWebRequest)request; 
     httpRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate; 
     return httpRequest; 
    } 

    protected override WebResponse GetWebResponse(WebRequest request) 
    { 
     WebResponse response = base.GetWebResponse(request); 
     String setCookieHeader = response.Headers[HttpResponseHeader.SetCookie]; 

     if (setCookieHeader != null) 
     { 
      //do something if needed to parse out the cookie. 
      try 
      { 
       if (setCookieHeader != null) 
       { 
        Cookie cookie = new Cookie(); //create cookie 
        this.CookieContainer.Add(cookie); 
       } 
      } 
      catch (Exception) 
      { 

      } 
     } 
     return response; 

    } 
}
