(微信API接口开发) 使用HttpWebRequest进行请求时发生错误：基础连接已关闭，发送时发生错误处理

最近调试原来的微信模拟登陆时发生了“基础连接已关闭，发送时发生错误”的错误提示，原来都是好好的，只是很久没用了。

出错代码如下：

?
1
2
3
4
5
6
7
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(); 

　　

经过一番Google和试验，答案既如此简单，增加如下一句：

            ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

复制代码 
1 req.CookieContainer = cookie; 2 req.Method = "GET"; 3 req.ProtocolVersion = HttpVersion.Version10; 4 ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;  5 HttpWebResponse res = (HttpWebResponse)req.GetResponse(); 6 StreamReader rd = new StreamReader(res.GetResponseStream()); 7 string theContent = rd.ReadToEnd();
复制代码
