看到有朋友回復評論不知道如何利用上一篇我的寫的58同城的登陸，我在這里把代碼給大家看下吧，我封裝好的工具類：我的操作思路是這樣子的。因為我是在winform里面坐的程序，之前沒有用WebBrowser組件，一直用的HttpWebrequest，但是這個js的話，只有利用webBrowser來進行了。大體思路就是1：用WebBrowser來加載這個js，這個js我下載到了本地2：根據對應的函數來進行調用。

調用方法：

?

?

[csharp] view plaincopyprint?

//?獲取時間戳 ??

????????????DateTime?d1?=?DateTime.Now.AddHours((double)(-8));??

????????????DateTime?d2?=?new?DateTime(1970,?1,?1);??

????????????long?d?=?(long)d1.Subtract(d2).TotalMilliseconds;??

??

????????????Post58comUtil?util?=?new?Post58comUtil(loginUserPassword,?d);??

?

// 獲取時間戳DateTime d1 = DateTime.Now.AddHours((double)(-8));DateTime d2 = new DateTime(1970, 1, 1);long d = (long)d1.Subtract(d2).TotalMilliseconds;Post58comUtil util = new Post58comUtil(loginUserPassword, d);

那么16str和32str都可以調用了。。
