Java模仿HTTP Get Post要求 輕松完成校園BBS主動回帖

Java模仿HTTP Get Post要求 輕松完成校園BBS主動回帖。本站提示廣大學習愛好者:(Java模仿HTTP Get Post要求 輕松完成校園BBS主動回帖)文章只能為提供參考,不一定能成為您想要的結果。以下是Java模仿HTTP Get Post要求 輕松完成校園BBS主動回帖正文


本文實例為年夜家分享了Java模仿HTTP Get Post要求,校園BBS主動回帖功效,供年夜家參考,詳細內容以下

設計思緒

找到帖子鏈接的聚集,最初面數字變更, 便可以獲得分歧的帖子

避免帖子揭橥會又被刪了的情形, 停止斷定帖子能否存在

遍歷這個聚集, 對每一個鏈接做回帖的POST要求

重難點

Note:

  • 回帖須要用戶登錄信息
  • 一種是應用Cookie
  • 另外一種是停止模仿登錄
  • 本文彩用前者

代碼

代碼比擬簡略,留意事項是找到本身的Cookie,賦給String yourCookeie便可以直接運轉

重要就是斷定帖子存不存在,這是一個get要求,然後用post發送一個回帖,回帖信息在mapData.put(“message”, “友誼幫頂了”)中 硬編碼為”友誼幫頂了”,你可以修正
