我正在制作一个简单的REST客户端以在我的C＃应用​​程序中使用。在Windows上的.net中它与http：//和https：//连接一起使用时效果很好。在Ubuntu
10.10上的Mono
2.6.7中（也用2.8测试了相同的结果），只有http：//可以工作。https：//连接在request.GetResponse（）方法上引发此异常：

Unhandled Exception: System.Net.WebException: Error getting response stream (Write: The authentication or decryption has failed.): SendFailure ---> System.IO.IOException: The authentication or decryption has failed. ---> Mono.Security.Protocol.Tls.TlsException: Invalid certificate received from server.

我还没有找到解决此问题的任何方法。任何人都知道为什么会发生这种情况以及如何解决它？

同样，这仅在Mono中失败，.Net建立连接似乎没有任何问题。

这是调用代码：

public JToken DoRequest(string path, params string[] parameters) {
    if(!path.StartsWith("/")) {
        path = "/" + path;
    }
    string fullUrl = url + path + ToQueryString(parameters);

    if(DebugUrls) Console.WriteLine("Requesting: {0}", fullUrl);

    WebRequest request = HttpWebRequest.CreateDefault(new Uri(fullUrl));
    using(WebResponse response = request.GetResponse())
    using(Stream responseStream = response.GetResponseStream()) {
        return ReadResponse(responseStream);
    }
}
