  • [转载]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

    转载,原文来自 http://blog.csdn.net/hawksoft/article/details/21776009

    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:

    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;
    通过代码如下:

    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;  
               ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;  
                HttpWebResponse res = (HttpWebResponse)req.GetResponse();  
                StreamReader rd = new StreamReader(res.GetResponseStream());  
                string theContent = rd.ReadToEnd();
