.net 登录博客园 并且发表文章一篇

目的：用.net代码登录.net并且提交文章一篇

注意：对于asp.net页面中的post请求服务器端会对提交的__VIEWSTATE、__EVENTVALIDATION验证，所以请求时需要提交这两个字段内容

 

获取__VIEWSTATE、__EVENTVALIDATION两个字段内容，且提交数据登录园子

　　　　　　//获取到url页面的html内容

            var loginpagehtml = RequestHelper.GetResponseContent(url);



            //获取页面中的__VIEWSTATE， __EVENTVALIDATION

            __VIEWSTATE = Regex.Match(loginpagehtml, reg1).Groups[1].Value;

            __EVENTVALIDATION = Regex.Match(loginpagehtml, reg2).Groups[1].Value;



            //提交的数据字典

            Dictionary<string, string> dicdata = new Dictionary<string, string>()

            {

                {"__VIEWSTATE",__VIEWSTATE},

                {"__EVENTVALIDATION", __EVENTVALIDATION},

                {"tbUserName", "username"},

                {"tbPassword", "password"},

                {"__EVENTTARGET",""},

                {"__EVENTARGUMENT", ""},

                {"btnLogin", "登  录"}

            };



            //拼接提交的数据字典为a=1&b=2格式

            var postdata = dicdata.Select(dic => string.Format("{0}={1}", dic.Key, dic.Value)).Aggregate((a, b) => a + "&" + b);



            //提交登录页面request，并且获取response对象

            var response = RequestHelper.GetResponse(url, postdata, (head) => { head.Method = "POST"; head.UserAgent = "Mozilla/5.0"; head.CookieContainer = cc; });

　　

登录后到发表文章页面提交文章一篇，代码如下：

            //提交一篇文章

            var editpostpagehtml = RequestHelper.GetResponseContent("http://www.cnblogs.com/lyroge/admin/EditPosts.aspx?opt=1", null, (head) => { head.CookieContainer = cc; head.AllowAutoRedirect = true; });

            __VIEWSTATE = Regex.Match(editpostpagehtml, reg1).Groups[1].Value;            



            var dicdata = new Dictionary<string, string>()

            {

                {"__VIEWSTATE",__VIEWSTATE},            

                {"__EVENTTARGET",""},          

                {"__EVENTARGUMENT", ""},

                {"Editor$Edit$lkbPost", "发布"},

                {"Editor$Edit$txbTitle", ".net 登录博客园 并且发表文章一篇"},

                {"Editor$Edit$EditorBody", "<p>内容我自己填写</p>"},

                {"Editor$Edit$APOptions$APSiteHome$chkDisplayHomePage", "on"},

                {"Editor$Edit$Advanced$ckbPublished", "on"},

                {"Editor$Edit$Advanced$chkComments","on"},

                {"Editor$Edit$Advanced$chkMainSyndication", "on"},

                {"Editor$Edit$Advanced$txbEntryName",""},

                {"Editor$Edit$Advanced$txbExcerpt", ""},

                {"Editor$Edit$Advanced$txbTag",""},

                {"Editor$Edit$Advanced$tbEnryPassword", ""}

            };

            

            //注意对提交的数据要进行urlencode编码

            var postdata = dicdata.Select(dic => string.Format("{0}={1}", System.Web.HttpUtility.UrlEncode(dic.Key), System.Web.HttpUtility.UrlEncode(dic.Value))).Aggregate((a, b) => a + "&" + b);

            

            var response = RequestHelper.GetResponse("http://www.cnblogs.com/lyroge/admin/EditPosts.aspx?opt=1", postdata, (head) =>

            {

                head.Method = "POST"; head.UserAgent = "Mozilla/5.0"; head.CookieContainer = cc; head.Referer = "http://www.cnblogs.com";

            });
