Java 模擬HTTP Get Post請求

設計思路

找到帖子鏈接的集合, “http://rs.xidian.edu.cn/forum.php?mod=viewthread&tid=774210” 最后面774210數字變化, 就可以得到不同的帖子
防止帖子發表會又被刪了的情況, 進行判斷帖子是否存在
遍歷這個集合, 對每個鏈接做回帖的POST請求

重難點

Note:

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

代碼

代碼比較簡單，

注意事項是找到自己的Cookie，賦給String yourCookeie

就可以直接運行

主要就是判斷帖子存不存在，這是一個get請求
然后用post發送一個回帖，回帖信息在mapData.put(“message”, “友情幫頂了”)中硬編碼為”友情幫頂了”，你可以修改
