Accesso al sito Web tramite C#

Question

Ho provato tutto ciò che posso trovare sul Web su come implementarlo per accedere a questo sito. Ecco l'errore più recente.

// 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); 
     }    
} 

qui è anche i dati rilevanti dal sito (so che i gettoni sono diverse nell'esempio li ho fatto lo stesso e non funziona)

<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> 

Answer 1

provare in questo modo:

 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 

    } 

Extra Class usati:

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; 

    } 
}
