c# - 带有显示错误的 Internet 代理服务器的 Windows WCF 客户端服务器违反了协议(protocol)。部分=响应状态行

Question

我们的团队试图创建一个 Windows 应用程序 (c#) 以使用 Internet 代理服务器调用 WCF 服务

调用 WCF 服务时显示异常“服务器违反了协议(protocol)。Section=ResponseStatusLine”

请给出解决这个问题/任何其他替代解决方案的建议

//Code for creating proxy
public static DevicesServiceClient CreateProxy()
{
  var proxy = new DevicesServiceClient("BasicHttpBinding_IDevicesService");

  BasicHttpBinding binding = new BasicHttpBinding();
  binding.Security.Mode = BasicHttpSecurityMode.None;
  binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
  binding.UseDefaultWebProxy = false;
  binding.ProxyAddress = new Uri(string.Format("http://{0}:{1}", "192.168.0.20","808"));
  proxy.Endpoint.Binding = binding;

  proxy.ClientCredentials.UserName.UserName = "Username";
  proxy.ClientCredentials.UserName.Password = "Password";
}

服务器堆栈跟踪:

我在 app.config 中的客户端代码

我在 web.config 中的服务器端代码

我以前没有见过这个异常，但我已经遇到了很大的问题，无法让代理以这种方式工作。我不知道为什么，但是在 BasicHttpBinding 中设置代理地址并将默认代理设置为 false 对我来说从来没有用过。我总是不得不使用默认 Web 代理并在那里设置 URL，或者创建全新的自定义绑定(bind)并在 http 传输绑定(bind)元素中设置代理 URL。
