c#模擬登錄獲取Cookie

這里是使用 CookieContainer 獲取 到 Cookie

string contentUrl = "https://home.cnblogs.com/u/xinjian/";
            HttpWebRequest reqContent = (HttpWebRequest)WebRequest.Create(contentUrl);
            reqContent.Method = "GET";
            reqContent.AllowAutoRedirect = false;//服務端重定向。一般設置false
            reqContent.ContentType = "application/x-www-form-urlencoded";//數據一般設置這個值，除非是文件上傳

    var  cookie = new CookieContainer();

reqContent.CookieContainer = cookie; 
reqContent.CookieContainer.SetCookies(reqContent.RequestUri, cookies);//將登錄的cookie值賦予此次的請求。  
HttpWebResponse respContent = (HttpWebResponse)reqContent.GetResponse(); 
string html = new StreamReader(respContent.GetResponseStream()).ReadToEnd();
//獲取到的cookie就在變量cookie中。
