的HTTPRequest頭不在Wireshark的

Question

我設置了一些HTTP請求頭是這樣的：

 this.Url = new Uri(u); 
     HttpWebRequest http = (HttpWebRequest)WebRequest.Create(Url); 
     WebResponse response = http.GetResponse(); 

     //headers 
     http.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0\r\n"; 
     http.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n"; 
     http.Headers.Add("Accept-Encoding", "gzip,deflate,sdch'r'n"); 
     http.Headers.Add("Accept-Language", "en-US,en;q=0.9\r\n"); 
     http.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.3\r\n"); 

我捕捉他們是這樣的：

  for (count = 0; count < http.Headers.Keys.Count; count++) 
     { 
      headerKey = http.Headers.Keys[count]; 
      headerValue = http.Headers[headerKey]; 

      if (headerValue != null) 
      { 
       if (headerKey == null) 
       { 
        requestbuffer.Append(headerValue); 
        requestbuffer.Append(Newline); 
       } 
       else 
       { 
        requestbuffer.Append(headerKey + ": " + headerValue); 
        requestbuffer.Append(Newline); 
       } 
      } 
     } 

當我運行測試工具，一切似乎都很好：

• 主持人：domain.com
• 連接：保持活動
• User-Agent：Mozilla/5.0（Windows NT 6.1; WOW64; RV：17.0）壁虎/ 20100101火狐/ 17.0
• 接受：text/html的，應用/ XHTML + xml的，應用/ XML; Q = 0.9，/; Q = 0.8
• 接受編碼：gzip，放氣，SDCH接受語言：EN-US，EN; q = 0.9
• 接收字符集：ISO-8859-1，utf-8; q = 0.7，*; q = 0.3

然而在Wireshark的和Fiddler只發送以下標題：

• GET/HTTP/1.1
• 主機：domain.com

任何想法爲什麼這可能是？

Answer 1

是的，你要設置頁眉您發送請求後。

試試這個：

//headers 
    http.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0\r\n"; 
    http.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n"; 
    http.Headers.Add("Accept-Encoding", "gzip,deflate,sdch'r'n"); 
    http.Headers.Add("Accept-Language", "en-US,en;q=0.9\r\n"); 
    http.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.3\r\n"); 

    WebResponse response = http.GetResponse(); 

Answer 2

您正在嘗試在之後添加標頭，您稱爲http.GetResponse()。在之後，這是請求已發送。它改成這樣：

this.Url = new Uri(u); 
HttpWebRequest http = (HttpWebRequest)WebRequest.Create(Url); 

//headers 
http.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0\r\n"; 
http.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n"; 
http.Headers.Add("Accept-Encoding", "gzip,deflate,sdch'r'n"); 
http.Headers.Add("Accept-Language", "en-US,en;q=0.9\r\n"); 
http.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.3\r\n"); 

using (WebResponse response = http.GetResponse()) 
{ 
    // Do whatever 
} 

（請注意，你真的應該被處置的響應。）
