在.NET C＃中将XML发布到Web服务并接收响应 [英] Posting XML to Web service in .NET C# and recieving response

问题描述

我有一个XML请求文档，我将其发布到WebService。



我的项目已上传到我的Web服务器上。网络服务提供商仅允许访问我的网络服务器IP。



但是当我请求响应时我收到错误''服务器错误 - 500 - 你不是允许访问系统 - //这里显示我的客户端机器的IP，我从中访问该页面//



代码如下。



请帮忙。

 受保护  void  Page_Load（ object  sender，EventArgs e）
 { 
 WebRequest req =  null ; 
 WebResponse rsp =  null ; 
 尝试 
 {
  string  fileName = Server.MapPath（< span class =code-string> 〜\\HotelValuedAvailRQ.xml）; 
  string  uri =   http：// 212.170.239.71/appservices/http/FrontendService; 
 req = WebRequest.Create（uri）; 
  //   req.Proxy = WebProxy.GetDefaultProxy（）; //启用使用代理 
 req.Method =   POST;  //  发布方法 
 req.ContentType =    text / xml;  //  内容类型 
  //  使用基于文本的编写器包装请求流 
 StreamWriter writer =  new  StreamWriter（ req.GetRequestStream（））; 
  //  将XML文本写入流 
 writer.WriteLine（< span class =code-keyword> this  .GetTextFromXMLFile（fileName））; 
 writer.Close（）; 
  //  将数据发送到网络服务器 
 rsp = req.GetResponse（ ）;   //  我在这里收到错误  
 StreamReader sr =  new  StreamReader（rsp.GetResponseStream（））; 
  string  result = sr.ReadToEnd（）; 
 sr.Close（）; 
 Response.Write（result）; 
 
} 
  catch （WebException webEx）
 {
 Response.Write（webEx.Message.ToString （））; 
 Response.Write（webEx.StackTrace.ToString（））; 
} 
  catch （例外情况）
 {
 Response.Write（ex.Message.ToString（））; 
 Response.Write（ex.StackTrace.ToString（））; 
} 
 最后 
 {
  if （req ！=  null ）req.GetRequestStream（）。Close（）; 
  if （rsp！=  null ）rsp.GetResponseStream（）。Close（）; 
} 
} 
  //  从本地系统读取xml数据的函数 
  ///   <  < span class =code-summarycomment>摘要 >  
   // /  从文件
中读取XML数据  ///   <   / summary  >  
   ///   <   param     name =file >  <   / param  >  
   ///   <  返回 > 以XML字符串格式返回文件内容<   / returns  >  
   private   string  GetTextFromXMLFile（ string  file ）
 {
 StreamReader reader =  new  StreamReader（file）; 
  string  ret = reader.ReadToEnd（）; 
 reader.Close（）; 
 返回 ret; 
} 

解决方案

显然，您的服务器未配置为允许您访问。对代码进行任何更改都不会更改有关您访问服务器的权限的消息。如果你怀疑这一点，写一个传递int的服务，看看会发生什么。

 req.ContentType =   text / xml;  //  内容类型 
 
 req.Credentials = CredentialCache.DefaultNetworkCredentials; 

rsp =（HttpWebResponse）req.GetResponse（）;



这应该有用!!

I have a XML request document which I am Posting to the WebService.

I have my project uploaded on my web server. The webservice provider has allowed access to my web server IP only.

But I am getting error when I am requesting the response ''Server Error - 500 - You are not allowed to access the system - //here it is showing my client machine''s IP from which I am accessing the page//

The code is given below.

Please help.

protected void Page_Load(object sender, EventArgs e)
    {
        WebRequest req = null;
        WebResponse rsp = null;
        try
        {
            string fileName = Server.MapPath("~\\HotelValuedAvailRQ.xml");
            string uri = "http://212.170.239.71/appservices/http/FrontendService";
            req = WebRequest.Create(uri);
            //req.Proxy = WebProxy.GetDefaultProxy(); // Enable if using proxy
            req.Method = "POST";        // Post method
            req.ContentType = "text/xml";     // content type
            // Wrap the request stream with a text-based writer
            StreamWriter writer = new StreamWriter(req.GetRequestStream());
            // Write the XML text into the stream
            writer.WriteLine(this.GetTextFromXMLFile(fileName));
            writer.Close();
            // Send the data to the webserver
            rsp = req.GetResponse(); //I am getting error over here
            StreamReader sr = new StreamReader(rsp.GetResponseStream());
            string result = sr.ReadToEnd();
            sr.Close();
            Response.Write(result);
            
        }
        catch (WebException webEx)
        {
            Response.Write(webEx.Message.ToString());
            Response.Write(webEx.StackTrace.ToString());
        }
        catch (Exception ex)
        {
            Response.Write(ex.Message.ToString());
            Response.Write(ex.StackTrace.ToString());
        }
        finally
        {
            if (req != null) req.GetRequestStream().Close();
            if (rsp != null) rsp.GetResponseStream().Close();
        }
    }
        //Function to read xml data from local system
  /// <summary>
  /// Read XML data from file
  /// </summary>
  /// <param name="file"></param>
  /// <returns>returns file content in XML string format</returns>
  private string GetTextFromXMLFile(string file)
  {
   StreamReader reader = new StreamReader(file);
   string ret = reader.ReadToEnd();
   reader.Close();
   return ret;
  }

解决方案

Obviously your server is NOT configured to give you access. No change to your code will change a message that is about your rights to access the server. If you doubt this, write a service that passes an int, and see what happens.

req.ContentType = "text/xml"; // content type

req.Credentials = CredentialCache.DefaultNetworkCredentials;

rsp = (HttpWebResponse) req.GetResponse();

This should work!!
