本編部落格通過WinPcap+Wireshark進行無線網路抓包，獲取基本資訊，進而模擬其他使用者的app請求。

本編部落格主要學習交流，其次告訴廣大網友切勿貪小便宜使用未知WiFi。

讀者們首先需要下載並安裝WinPcap和Wireshark，安裝Wireshark之前必須安裝winPcap，可以通過官網下載：

Wireshark ：https://www.wireshark.org/download.html

WinPcap：http://www.winpcap.org/install/

1、安裝成功之後，使用360WiFi、獵豹WiFi等開放自己的WiFi，開啟Wireshark監測自己的無線網路

2、使用接入WIFI的裝置，這時將捕獲到裝置操作資訊。

通過捕獲到的資料包，可以查詢通訊的協議protocol、請求的資訊request以及響應資訊response等

3、通過前兩步，能過查詢資料資訊，接下來模擬一個客戶端，以聯通簽到領金幣為例，使用java實現，相關jar包及說明http://blog.csdn.net/myfmyfmyfmyf/article/details/46860025
