.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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

//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";

});
