带SSL的C＃Websocket客户端 [英] C# Websocket client with SSL

问题描述

您好，

我想问一下，有人曾在C＃中编写过Web套接字客户端，例如：控制台应用。我确实找到了一些外部库，但要么他们没有SSL支持，要么没有任何区别。我使用的是.NET 3.5，我无法改变它。不幸的是我的客户端正在使用WebSocket，我别无选择。

解决方案

要发送请求并收到回复，您可以使用：

 HttpWebRequest req =（HttpWebRequest）WebRequest.Create（url）; 

其中url是查询字符串https：/ / ...。



与SSL的主要区别在于您必须验证证书：

  //  在您的代码中只需要一次的任何请求之前 
  //  你可以放在应用程序的开头 
 
 RemoteCertificateValidationCallback remote = ValidateServerCertificate; 
 ServicePointManager.ServerCertificateValidationCallback = remote; 
 
 
  public   bool  ValidateServerCertificate（
  object  sender，
 X509Certificate certificate，
 X509Chain chain，
 SslPolicyErrors sslPolicyErrors）
 {
  return   true ;  //  始终接受......真的应该检查 
} 

Hello,
I would like to ask of anyone ever wrote web socket client in C# as e.g. console application. I did find some external libraries but either they had no SSL support or it didn't make any difference. I'm using .NET 3.5 and I can't change it. Unfortunately my client is using WebSocket and I have no other choice.

解决方案

To send requests and receive responses you can use:

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);

where url is the query string "https://...".

The main difference with SSL is you must verify the certificate:

//before any request you need this only once in your code
//you can put in beginning of you app

RemoteCertificateValidationCallback remote = ValidateServerCertificate;
ServicePointManager.ServerCertificateValidationCallback = remote;
                

public bool ValidateServerCertificate(
            object sender,
            X509Certificate certificate, 
            X509Chain chain,
            SslPolicyErrors sslPolicyErrors)
        {
            return true; //always accept... really should check it
        }
