本文實例為大家分享了Java模擬HTTP Get Post請求，校園BBS自動回帖功能，供大家參考，具體內(nèi)容如下
設(shè)計思路
找到帖子鏈接的集合，最后面數(shù)字變化, 就可以得到不同的帖子
防止帖子發(fā)表會又被刪了的情況, 進(jìn)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(jìn)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(fā)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
