使用代理服务器连接到webservice时出错（System.Net.WebException：无法连接到远程服务器） [英] error in connection to webservice by using proxy server (System.Net.WebException: Unable to connect to the remote server)

问题描述

亲爱的..



i连接到网络服务以获取特定结果，我的Windows应用程序根据网络服务的响应下载许多文件/>


只有在我的网络浏览器中使用代理程序模拟代理才会出现问题

这是我做的步骤：

dear all..

i am connecting to a web service to get a specific results and my windows applications download many files according to response from web-service

the problem appears only when using a proxy in my internet explorer using program "analog proxy"
this is the steps i made:

tools->internet options->connections->Lan settings-> and i checked use proxy server for Lan..... with address: 192.168.1.240 and port:6588

我的代码连接到网络的服务是：

my code to connect to web-service is:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.o-survey.com");

IWebProxy proxy = request.Proxy;
if (proxy != null)
{
    MessageBox.Show("Proxy: {0}"+ proxy.GetProxy(request.RequestUri));
}
else
{
    MessageBox.Show("Proxy: {0}Proxy is null; no proxy will be used");
}

WebProxy myProxy = new WebProxy();
Uri newUri = new Uri("http://162.168.1.240:6588");
// Associate the newUri object to 'myProxy' object so that new myProxy settings can be set.
myProxy.Address = newUri;
// Create a NetworkCredential object and associate it with the
// Proxy property of request object.
myProxy.Credentials = new NetworkCredential("john", "johngra");
request.Proxy = myProxy;

和在app.config中我放下以下行

and in app.config i put the following line

<system.net>

  <defaultProxy enabled="true" useDefaultCredentials="true" >
  </defaultProxy>

</system.net>

i得到此错误：

i got this error:

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 192.168.1.240:6588

推荐答案

你可能需要阅读什么代理服务器是：



代理服务器 [ ^ ]



在您尝试连接并创建代理的计算机上，它必须运行代理服务器。这是一个重新路由请求的软件。在您的情况下，192.168.1.240计算机需要在其上安装代理服务器并进行配置以路由流量。然后您的另一台计算机可以将其用作代理服务器。否则它会给你一个无法连接的消息。

You may need to read up on what proxy servers are:

Proxy Server[^]

On the computer that you are trying to connect to and make the proxy, it MUST be running a proxy server. This is a piece of software that re-routes requests. In your case, the 192.168.1.240 computer needs to have a proxy server INSTALLED on it, and configured, to route traffic. Then your other computer can use it as a proxy server. Otherwise it will give a the "unable to connect" message that you are getting.

WebRequest 对象有一个有用的属性 DefaultWebProxy



这会返回你正在尝试的 IProxy 对象根据您的系统代理设置进行配置。

The WebRequest object has a useful property DefaultWebProxy

This returns the IProxy object you're trying to configure based on your systems proxy settings.
