C#模拟POST和GET请求

 

 

 

模拟验证的cookie

 

            CookieContainer baseCookieContainer = new CookieContainer();

            Cookie cookie2 = new Cookie("ASP.NET_SessionId", "sur1dby21qru00ol3bqcamqd");
            cookie2.Domain = "106.37.230.254";
            baseCookieContainer.Add(cookie2);

 

模拟POST提交数据

 

 /// <summary>
        /// 返回LoginOncookie的值
        /// </summary>
        /// <param name="username"></param>
        /// <param name="password"></param>
        /// <returns></returns>
