Question

我使用以下代码向https网站发出请求：

 webRequest = (HttpWebRequest)WebRequest.Create(new Uri(urlDestination));
            webRequest.Method = "POST";
            webRequest.ContentType = "application/x-www-form-urlencoded";
            webRequest.ContentLength = bytes.Length;

            Stream writer = webRequest.GetRequestStream();
            writer.Write(bytes, 0, bytes.Length);
            if (writer != null)
            {
                writer.Close();
            }

            response = new StreamReader(webRequest.GetResponse().GetResponseStream()).ReadToEnd();

并收到此错误：

System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Received an unexpected EOF or 0 bytes from the transport stream.

我在网上查看错误后发现了这个解决方案并且没有用完：

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

带到供应商后，他说他遇到了这个错误

SSL_do_handshake() failed (SSL: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher) while SSL handshaking

我知道错误来自我的部分，但不知道如何让请求跳过错误。

ssl3声明确实解决了我的问题，但我遇到了另一个不适用于我的建议，但是由于你有一个内容长度声明，它会对你有所帮助。

建议删除该声明。

我的工作代码如下：

//Create WebRequest
Uri JsonUri = new Uri(new Uri(JIRAInstanceUri), ServiceUri);
WebRequest RestWebRequest = WebRequest.Create(JsonUri);
RestWebRequest.Method = "GET";
RestWebRequest.ContentType = "application/json";
//Add proxy to WebRequest
ProxyServer.BypassArrayList.Add(JsonUri);
RestWebRequest.Proxy = ProxyServer;
//Setup authorization
string Base64Credentials = GetEncodedCredentials(UserName, Password);
RestWebRequest.Headers["Authorization"] = "Basic " + Base64Credentials;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

发送时发生意外错误。来自传输流的EOF或0字节
