利用客户端程序自动发送文章。

1）获取登录界面,拼装post数据。（引用HtmlAgilityPack)

            string postdata = null;
            HtmlWeb hweb = new HtmlWeb();
            HtmlDocument hdoc = hweb.Load(loginurl);
            foreach (HtmlNode hnode in hdoc.DocumentNode.Descendants("form"))
            {
                if (hnode.Attributes["name"].Value != "loginform") continue;
                foreach (HtmlNode subhnode in hnode.SelectNodes("//input"))
                {
                    if (!subhnode.Attributes.Contains("name")) continue;
                    string n = subhnode.Attributes["name"].Value;
                    string v = subhnode.Attributes["value"].Value;
                    if ( string.IsNullOrEmpty(v) )
                    {
                        if ( n.IndexOf("log") >=0) v = loginname;
                        if ( n.IndexOf("pwd") >=0) v = pwd;                        
                    }
                    v = System.Web.HttpUtility.UrlEncode(v,hdoc.Encoding);
                    postdata += string.Format("{0}={1}&",n, v);
                }
            }
            if (!string.IsNullOrEmpty(postdata)) postdata = postdata.Trim().TrimEnd('&');

2）登录。

必须设置request.AllowAutoRedirect = false，否则直接跳转管理界面，且由于cookie问题，再跳转回登录界面。

CookieContainer cc = new CookieContainer();
            HttpWebRequest request = GetHttpWebRequest(loginurl,"POST");
            request.CookieContainer = cc;
            request.AllowAutoRedirect = false;
            byte[] pbytes = Encoding.UTF8.GetBytes(postdata);
            using ( Stream stream =  request.GetRequestStream() )
            {
                stream.Write(pbytes, 0, pbytes.Length);
            }
            HttpWebResponse response = request.GetResponse() as HttpWebResponse;
            if (response.StatusCode == HttpStatusCode.Found)
            {

3）获取管理界面。

理论上，cc 中已包含需要的cookie信息，可继续利用 HttpWebRequest 访问管理界面，但实际并不如此。利用fiddler查看程序和浏览器在登录后获取管理界面，比较后如下：

程序：Cookie: wordpress_test_cookie=WP+Cookie+check; wordpress_logged_in_33496cfac029fe8684ecd0304af8c268=admin%7C1355837731%7Cfaffab04dbd1b56428680070b340e099

浏览器：Cookie: wordpress_33496cfac029fe8684ecd0304af8c268=admin%7C1354800972%7C20a76f98dc39528a6d99de411b82120b; wp-settings-time-1=1354627518; wordpress_test_cookie=WP+Cookie+check; wordpress_logged_in_33496cfac029fe8684ecd0304af8c268=admin%7C1354800972%7C5a1f7e076c62af9733457fd0ddca5482

显然Cookie丢失了。两者登录成功后response的内容是一致的，如下：

Set-Cookie: wordpress_33496cfac029fe8684ecd0304af8c268=admin%7C1354802748%7C2a761d1e3dcda51e283132a48d66b83f; path=/wp/wp-content/plugins; httponly
Set-Cookie: wordpress_33496cfac029fe8684ecd0304af8c268=admin%7C1354802748%7C2a761d1e3dcda51e283132a48d66b83f; path=/wp/wp-admin; httponly
Set-Cookie: wordpress_logged_in_33496cfac029fe8684ecd0304af8c268=admin%7C1354802748%7C67b3113747f9bfc16830c786893b54c0; path=/wp/; httponly

其中红色部分即CookieContainer丢失的部分。未继续研究HttpWebRequest，转战Socket，如下：

　　3.1）从header中获取cookie信息

string setcookies = response.Headers[HttpResponseHeader.SetCookie];
                setcookies = setcookies.Replace(", ", " ");
                foreach (string sc in setcookies.Split(','))
                {
                    string path =null;
                    string scname = null;
                    string scvalue = null;
                    foreach (string svalue in sc.Split(';'))
                    {
                        string s = svalue.Trim();
                        if (s.Contains("expires")) continue;
                        if (s.Contains('='))
                        {
                            string[] nv = s.Split('=');
                            string n = nv[0];
                            string v = nv[1];
                            if (n == "path") path = v;
                            else
                            {
                                scname = n;
                                scvalue = v;
                            }
                        }
                    }
                    Cookie c = new Cookie(scname, scvalue);
                    cc.Add(new Uri(wpsiteurl + path), c);
                    if ( reqcookie==null || !reqcookie.Contains(scname))
                    {
                        reqcookie += string.Format("{0}={1}; ", scname, scvalue);
                    }
                }

　　3.2）利用Socket发送数据

                //socket 方式获取发布文章界面。
                string reqstr = string.Format("GET {0} HTTP/1.1\r\nHost: {1}", adminurl, wpuri.Host);
                reqstr += "\r\nReferer: " + loginurl;
                reqstr += "\r\nUser-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1";
                reqstr += "\r\nCookie: " + reqcookie;
                reqstr += "\r\nConnection: Close\r\n\r\n";     
。。。

4）同1），从管理界面中获取发布文章的form（name="post"）信息，拼装post内容。

5) 利用3.1中的cookie，仍然用socket方式发送数据。

                //发布文章。                
                reqstr = string.Format("POST {0} HTTP/1.1\r\nHost: {1}", posturl, wpuri.Host);
                reqstr += "\r\nReferer: " + adminurl;
                reqstr += "\r\nUser-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1";
                reqstr += "\r\nCookie: " + reqcookie;
                reqstr += "\r\nContent-Length: " + postdata.Length;
                reqstr += "\r\nContent-Type: application/x-www-form-urlencoded";
                reqstr += "\r\nConnection: Close\r\n\r\n";
                reqstr += postdata;
