Question

我正在尝试使用HttpWebRequest类发送此页面的数据：

www.stage1.darotools.com/Quran.v1.admin/_FormsWizard/CreateForm.asp

但我遇到了登录验证问题。继承我的代码：

    System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
    string postData = "ctlMessageID=" + 348;
    postData += ("&ctlUserID=" + 7);
    postData += ("&ctlTitle=" + 7);
    postData += ("&ctlEmail=" + "rrawhi@gmail.com");
    postData += ("&ctlIsSystem=" + 0);
    postData += ("&ctlFormBody=");
    postData += ("&ctlEnableCaptcha=");
    postData += ("&ctlEmailAttachedFiles=");
    postData += ("&ctlMailingList=");
    postData += ("&ctlCommentaryTitle=" + 1);
    postData += ("&ctlIsActive=" + 2);
    postData += ("&ctlCommentaryPersonID=" + 6);
    postData += ("&ctlOrderKey=");
    postData += ("&Commentary_TextControl_html=" + "aaaaaaaaaaaa");
    postData += ("&controlValue4=" + 666666);
    postData += ("&ctlLanguageID=" + 1);
    postData += ("&ctlAya=" + 349);
    postData += ("&PathInfo=" + "dbsFramed, dbsFramed");
    postData += ("&Caller=" + "rawhi");
    byte[] data = encoding.GetBytes(postData);

    // Prepare web request...
    HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://stage1.darotools.com/Quran.v1.admin/_FormsWizard/CreateForm.asp");
    myRequest.Method = "POST";
    myRequest.ContentType = "application/x-www-form-urlencoded";
    myRequest.ContentLength = data.Length;
    Stream newStream = myRequest.GetRequestStream();
    // Send the data.
    newStream.Write(data, 0, data.Length);
    newStream.Close();

这是登录页面：

www.stage1.darotools.com/Quran.v1.admin/Login.asp

提前致谢。

Answer 1

首先，看起来你实际上并没有发送请求。要将POST请求发送到服务器，您需要请求响应：

HttpWebResponse response = (HttpWebResponse)myRequest.GetResponse();
string responseContent = null;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
 {
    //get the text content of the response, if needed
    responseContent = reader.ReadToEnd();
 }

此外，您发布的页面看起来正在寻找已建立且经过身份验证的会话。首先尝试将凭据发布到登录页面（http://stage1.darotools.com/Quran.v1.admin/Login.asp）。将HttpWebRequest.CookieContainer设置为新的CookieContainer（）实例。然后，再向CreateForm.asp页面发帖，但一定要设置新的HttpWebRequest.CookieContainer对象，以使用您在登录页面进行POST时使用的CookieContainer的相同实例。然后，从登录页面收到的cookie将被发送到CreateForm.asp页面，并且会从服务器的角度“维护”会话。例如：

CookieContainer m_cookies = new CookieContainer();
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://stage1.darotools.com/Quran.v1.admin/Login.asp");
...

HttpWebResponse response = (HttpWebResponse)myRequest.GetResponse();
HttpWebRequest formRequest = (HttpWebRequest)WebRequest.Create("http://stage1.darotools.com/Quran.v1.admin/_FormsWizard/CreateForm.asp");
formRequest.CookieContainer = myRequest.CookieContainer;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
 {
    //get the text content of the response, if needed
    responseContent = reader.ReadToEnd();
 }

Answer 2

尝试使用：

myRequest.Credentials = new NetworkCredential("username", "password", "domain"); // domain is not needed in case of forms authentication

如果这不起作用，您可以在登录页面上验证用户并在那里传递CookieContainer，然后在请求所需页面时重用该CookieContainer。

也许这个链接可以帮到你：

webrequest login session

keep session id over httpwebrequest

Answer 4

这里可能会发生一些不同的事情

尝试设置一些凭据

myRequest.Credentials = CredentialCache.DefaultCredentials;

// if we have a proxy set its creds as well
if( myRequest.Proxy != null )
{
     myRequest.Proxy.Credentials = CredentialCache.DefaultCredentials;
}

并确保您也设置了UserAgent和Accpet设置。

myRequest.UserAgent = "Foo";
myRequest.Accept = "*/*";

如果你添加这些，我认为你不会有任何问题。
