c#模拟登录获取Cookie

这里是使用 CookieContainer 获取 到 Cookie

string contentUrl = "https://home.cnblogs.com/u/xinjian/";
            HttpWebRequest reqContent = (HttpWebRequest)WebRequest.Create(contentUrl);
            reqContent.Method = "GET";
            reqContent.AllowAutoRedirect = false;//服务端重定向。一般设置false
            reqContent.ContentType = "application/x-www-form-urlencoded";//数据一般设置这个值，除非是文件上传

    var  cookie = new CookieContainer();

reqContent.CookieContainer = cookie; 
reqContent.CookieContainer.SetCookies(reqContent.RequestUri, cookies);//将登录的cookie值赋予此次的请求。  
HttpWebResponse respContent = (HttpWebResponse)reqContent.GetResponse(); 
string html = new StreamReader(respContent.GetResponseStream()).ReadToEnd();
//获取到的cookie就在变量cookie中。
