调用webapi错误:由于远程方已关闭传输流,身份验证失败

postman没问题,代码请求就报错:由于远程方已关闭传输流,身份验证失败
Fiddler抓包发现是 ssl安全传输协议 不一样不一致造成的错误

手动指定特定的安全传输协议
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(serviceUrl);
//ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls; //ServicePointManager.SecurityProtocol = (SecurityProtocolType)192 | (SecurityProtocolType)768 | (SecurityProtocolType)3072; //4.5版本以上可使用:ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11; HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
