Java模拟HTTP Get Post请求 轻松实现校园BBS自动回帖

本文实例为大家分享了java模拟http get post请求，校园bbs自动回帖功能，供大家参考，具体内容如下

设计思路

找到帖子链接的集合，最后面数字变化, 就可以得到不同的帖子

防止帖子发表会又被删了的情况, 进行判断帖子是否存在

遍历这个集合, 对每个链接做回帖的post请求

重难点

note:

• 回帖需要用户登录信息
• 一种是利用cookie
• 另一种是进行模拟登录
• 本文采用前者

代码

代码比较简单，注意事项是找到自己的cookie，赋给string yourcookeie就可以直接运行

主要就是判断帖子存不存在，这是一个get请求，然后用post发送一个回帖，回帖信息在mapdata.put(“message”, “友情帮顶了”)中 硬编码为”友情帮顶了”，你可以修改
