获取查询字符串变量webrequested

Question

我编程方式创建这样

 string url = "http://aksphases:201/min-konto/printpdf.aspx?id=149656222&name=Ink%20And%20Toner"; 
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
     request.CookieContainer = new CookieContainer(); // required for HttpWebResponse.Cookies 
     request.Method = "POST"; 
     request.ContentType = "application/x-www-form-urlencoded"; 
     byte[] data = Encoding.UTF8.GetBytes("email=mymail&password=1234"); 
     request.ContentLength = data.Length; 
     using (Stream stream = request.GetRequestStream()) 
     { 
      stream.Write(data, 0, data.Length); 
     } 
     HttpWebResponse myWebResponse = (HttpWebResponse)request.GetResponse(); 
     Stream ReceiveStream = myWebResponse.GetResponseStream(); 

一个Web请求，并在printpdf.aspx页面（你可以看到它的网址）我想要得到的查询字符串参数，当这个URL以编程方式执行时。当我尝试平常的方式

HttpContext.Current.Request.QueryString["id"] 

它不起作用。 有什么我在做错误的方式。还是有没有更好的方法来做到这一点？

究竟在Web应用程序中，你在调用它？

HttpContext.Current.Request.QueryString["id"] 

这里就是我想你应该尝试： 在您的客户端应用程序：

string url = "http://aksphases:201/min-konto/printpdf.aspx?id=149656222&name=Ink%20And%20Toner"; 
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 

    // try this 
    Debug.WriteLine("About to send request with query=\"{0}\"", request.RequestUri.Query); 
    // and check to see what gets printed in the debug output windows 

    request.CookieContainer = new CookieContainer(); // required for HttpWebResponse.Cookies 
    request.Method = "POST"; 
    request.ContentType = "application/x-www-form-urlencoded"; 
    byte[] data = Encoding.UTF8.GetBytes("email=mymail&password=1234"); 
    request.ContentLength = data.Length; 

，而在你的ASPX页面，试试这个：

protected void Page_Load(object sender, EventArgs e) { 
     var theUrl = this.Request.Url.ToString(); 
     Debug.WriteLine(theUrl); // is this the exact URL that you initially requested ? 
     // if you have FormsAuthentication or other redirects 
     // this might get modified if you're not careful 

     var theId = this.Request.QueryString["id"]; 
     Debug.WriteLine(theId); 
    }
