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
