最近调试原来的微信模拟登录时发生了“基础链接已关闭，发送时发生错误”的错误提示，原来都是好好的，只是好久没用了。cookie

出错代码以下：spa

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("https://mp.weixin.qq.com/cgi-bin/loginpage?t=wxm2-login&lang=zh_CN");///cgi-bin/loginpage?t=wxm2-login&lang=zh_CN  
            req.CookieContainer = cookie;  
            req.Method = "GET";  
            req.ProtocolVersion = HttpVersion.Version10;  
            HttpWebResponse res = (HttpWebResponse)req.GetResponse();  
            StreamReader rd = new StreamReader(res.GetResponseStream());  
            string theContent = rd.ReadToEnd();

通过一番Google和试验，答案既如此简单，增长以下一句：.net

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
经过代码以下：调试

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("https://mp.weixin.qq.com/cgi-bin/loginpage?t=wxm2-login&lang=zh_CN");///cgi-bin/loginpage?t=wxm2-login&lang=zh_CN code

req.CookieContainer = cookie;  
            req.Method = "GET";  
            req.ProtocolVersion = HttpVersion.Version10;  
           ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;  
            HttpWebResponse res = (HttpWebResponse)req.GetResponse();  
            StreamReader rd = new StreamReader(res.GetResponseStream());  
            string theContent = rd.ReadToEnd();
