最近想自動發(fā)帖回帖,拿某論壇試驗了一下,發(fā)現可行,不過后續(xù)沒有再使用,以免影響論壇正常運行。
1、帖子鏈接的格式為
http://bbs.***.***.**/forum.php?mod=viewthread&tid=774210
最后面774210數字變化, 就可以得到不同的帖子
2、防止帖子發(fā)表會又被刪了的情況, 進行判斷帖子是否存在
3、遞增后面的 id 數字, 對每個鏈接做回帖的 POST 請求
重難點
回帖需要用戶登錄信息
一種是利用Cookie
另一種是進行模擬登錄
本文采用前者
判斷 url 對應的帖子是否存在
有可能用戶發(fā)了帖子,比如 url 為 http://bbs.***.***.**/forum.php?mod=viewthread&tid=774200
后來該帖子用戶刪除了或者被管理員刪除了,雖然帖子不在了,但是該 tid=774200 還是存在的

模擬發(fā)帖
代碼比較簡單,注意事項是找到自己的Cookie,賦給String yourCookeie
用post發(fā)送一個回帖,回帖信息在 mapData.put("message", "友情幫頂了") 中

還有一個工具方法,將輸入流轉化為字節(jié)
