的HTML我想使用HttpWebRequest以下頁面獲得HTML:無法獲得

http://inkdispatch.com/brother

目前我使用:

public static string getHTML(string url) 
    { 
     string responseData = ""; 
     try 
     { 
      // System.Threading.Thread.Sleep(1000 * 1); 
      HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
      request.Accept = "application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*"; 
      request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E)"; 
      request.Timeout = 60000; 
      request.AllowAutoRedirect = false; 
      request.Method = "GET"; 
      request.Referer = "inkdispatch.com"; 
      request.CookieContainer = yummycookies; 
      request.KeepAlive = true; 

      HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
      if (response.StatusCode == HttpStatusCode.OK) 
      { 
       Stream responseStream = response.GetResponseStream(); 
       StreamReader myStreamReader = new StreamReader(responseStream); 
       responseData = myStreamReader.ReadToEnd(); 
      } 
      foreach (Cookie cook in response.Cookies) 
      { 
       yummycookies.Add(cook); 
      } 
      response.Close(); 
     } 
     catch (Exception e) 
     { 
      responseData = "An error occurred: " + e.Message; 
     } 

     return responseData; 

    } 

但我看不到任何東西,我得到沒有錯誤的迴應只是說,移動滲透,當我把相同的鏈接在瀏覽器中的作品。該鏈接附有一個令牌,但我確實從主頁面獲得了該信息,但仍有相同的問題。

UPDATE

我只設置:

request.AllowAutoRedirect = true; 

,但我得到的錯誤:

Too many automatic redirections were attempted. 
    at System.Net.HttpWebRequest.GetResponse() 
    at inkdispatchcomScraper.Program.getHTML(String url) 

,我有小提琴手開放足見其連連命中鏈接:

ANOTHER UPDATE

當我在IE中打開它使用重定向到/兄弟,但在代碼的情況下,它向前得到另一個ZENID螞蟻到這個情況持續發生我都看到了。

request.AllowAutoRedirect = true;

編輯

併爲您的第二問題,如下聲明yummycookies

public static string getHTML(string url) 
{ 
    CookieContainer yummycookies = new CookieContainer(); 
    ... 
}

我已更新了描述,請查看。 – confusedMind 2012-04-15 17:28:58

但它在我的電腦上正常工作。 (我只需要聲明'靜態CookieContainer yummycookies =新的CookieContainer();') – 2012-04-15 17:41:00

你打哪個鏈接?它適用於http://inkdispatch.com/,但沒有其他鏈接。 – confusedMind 2012-04-15 17:44:02

,當我試圖測試你的代碼,它失敗了,但另一個測試我發現下面的錯誤「太多的自動重定向已嘗試」。

在更新你的代碼,並再次測試,它的工作原理以及您提供的網址,HTML獲取正常。代碼在這裏。

public static string GetHtml2(string urlAddr) 
{ 
    if (urlAddr == null || string.IsNullOrEmpty(urlAddr)) 
    { 
     throw new ArgumentNullException("urlAddr"); 
    } 
    else 
    { 
     string result; 

     //1.Create the request object 
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddr); 
     //request.AllowAutoRedirect = true; 
     //request.MaximumAutomaticRedirections = 200; 
     request.Proxy = null; 
     request.UseDefaultCredentials = true; 

     //2.Add the container with the active 
     CookieContainer cc = new CookieContainer(); 


     //3.Must assing a cookie container for the request to pull the cookies 
     request.CookieContainer = cc; 

     HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
     using (StreamReader sr = new StreamReader(response.GetResponseStream())) 
     { 
      result = sr.ReadToEnd(); 
      //Close and clean up the StreamReader 
      sr.Close(); 
     } 
     return result; 
    } 
} 

希望這會好的。

謝謝你同樣的問題,我認爲我的一些互聯網設置可能:它工作時,我沒有這樣做: System.Net.ServicePointManager.Expect100Continue = false; WebHeaderCollection myWebHeaderCollection = request.Headers; //在請求中添加Accept-Language標頭(丹麥語)。 myWebHeaderCollection.Add(「Accept-Language:en-US」); myWebHeaderCollection.Add(「Accept-Encoding」,「gzip,deflate」); myWebHeaderCollection.Add(「Cookie」,「zenid = 9ea4d211ba2aa64cbaa148df5de4ab10」); – confusedMind 2012-04-15 20:08:17

在大多數情況下,如果您啓用了編碼「Accept-Encoding」,則「gzip,deflate」實時提取將無法正常工作,特別是在目標網站啓用此類編碼的情況下。 – irfanmcsd 2012-04-15 20:10:23

是的,我根本不使用它,但在這種情況下,我不得不復制一切只有它工作。 – confusedMind 2012-04-15 20:16:42
