【转】博客转发小工具2

昨天发了一个博客转发小工具有朋友说“能一键转发到各主流媒体站上就更好了”。一开始我以为会能难，需要登录啊还有cookie的管理啊模拟poss请求啊，乱七八糟一大堆。心想算啦，太累人，还不一定搞得定。后来心里总想着有没有什么简单的办法，就在网上查资料。最后皇天不负有心人让我找到了HttpClient。

ok，接着昨天的来。昨天的只能获取别人文章的内容复制到粘贴板。今天让它能一键发布。

首先需要解决的问题就是登录问题，不然可能是不能发布的。

登录博客园的代码

 1         /// <summary>
 2         /// 登录博客园
 3         /// </summary>
 4         /// <param name="username"></param>
 5         /// <param name="password"></param>
 6         /// <returns></returns>
 7         public bool LoginCnblogs(string username = "", string password = "")
 8         {
 9             httpClient = new HttpClient();
10             httpClient.MaxResponseContentBufferSize = 256000;
11             httpClient.DefaultRequestHeaders.Add("user-agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.143 Safari/537.36");
12             String url = "http://passport.cnblogs.com/login.aspx";
13             HttpResponseMessage response = httpClient.GetAsync(new Uri(url)).Result;
14             String result = response.Content.ReadAsStringAsync().Result;
15 
16             String __EVENTVALIDATION = new Regex("id=\"__EVENTVALIDATION\" value=\"(.*?)\"").Match(result).Groups[1].Value;
17             String __VIEWSTATE = new Regex("id=\"__VIEWSTATE\" value=\"(.*?)\"").Match(result).Groups[1].Value;
18             String LBD_VCID_c_login_logincaptcha = new Regex("id=\"LBD_VCID_c_login_logincaptcha\" value=\"(.*?)\"").Match(result).Groups[1].Value;
19 
20             //开始登录
21             url = "http://passport.cnblogs.com/login.aspx";
22             List<KeyValuePair<String, String>> paramList = new List<KeyValuePair<String, String>>();
23             paramList.Add(new KeyValuePair<string, string>("__EVENTTARGET", ""));
24             paramList.Add(new KeyValuePair<string, string>("__EVENTARGUMENT", ""));
25             paramList.Add(new KeyValuePair<string, string>("__VIEWSTATE", __VIEWSTATE));
26             paramList.Add(new KeyValuePair<string, string>("__VIEWSTATEGENERATOR", "C2EE9ABB"));
27             paramList.Add(new KeyValuePair<string, string>("__EVENTVALIDATION", __EVENTVALIDATION));
28             paramList.Add(new KeyValuePair<string, string>("tbUserName", username));
29             paramList.Add(new KeyValuePair<string, string>("tbPassword", password));
30             paramList.Add(new KeyValuePair<string, string>("LBD_VCID_c_login_logincaptcha", LBD_VCID_c_login_logincaptcha));
31             paramList.Add(new KeyValuePair<string, string>("LBD_BackWorkaround_c_login_logincaptcha", "1"));
32             //paramList.Add(new KeyValuePair<string, string>("CaptchaCodeTextBox", imgCode));
33             paramList.Add(new KeyValuePair<string, string>("btnLogin", "登  录"));
34             paramList.Add(new KeyValuePair<string, string>("txtReturnUrl", "http://home.cnblogs.com/"));
35             response = httpClient.PostAsync(new Uri(url), new FormUrlEncodedContent(paramList)).Result;
36             result = response.Content.ReadAsStringAsync().Result;
37 
38             if (result.Contains("用户登录"))
39                 return false;
40             else if (result.Contains("返回博客园首页"))
41                 return true;
42             else
43                 return false;
44         }

然后就是发布的代码

 1         /// <summary>
 2         /// 发布转发文章
 3         /// </summary>
 4         /// <returns></returns>
 5         public bool Release(string title = "", string content = "")
 6         {
 7             List<KeyValuePair<String, String>> paramList = new List<KeyValuePair<String, String>>();
 8             paramList.Add(new KeyValuePair<string, string>("__VIEWSTATE", @""));
 9             paramList.Add(new KeyValuePair<string, string>("__VIEWSTATEGENERATOR", "FE27D343"));
10             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$txbTitle", title));
11             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$EditorBody", content));
12             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$Advanced$ckbPublished", "on"));
13             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$Advanced$chkDisplayHomePage", "on"));
14             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$Advanced$chkComments", "on"));
15             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$Advanced$chkMainSyndication", "on"));
16             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$Advanced$txbEntryName", ""));
17             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$Advanced$txbExcerpt", ""));
18             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$Advanced$txbTag", ""));
19             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$Advanced$tbEnryPassword", ""));
20             paramList.Add(new KeyValuePair<string, string>("Editor$Edit$lkbPost", "发布"));
21 
22             HttpResponseMessage response = httpClient.PostAsync(new Uri("http://i.cnblogs.com/EditPosts.aspx?opt=1"), new FormUrlEncodedContent(paramList)).Result;
23             String result = response.Content.ReadAsStringAsync().Result;
24             if (result.Contains("发布成功"))
25                 return true;
26             else
27                 return false;
28 
29         }
