fiddler抓取摩拜單車資料包

Fiddler是一個http協議除錯代理工具，它能夠記錄並檢查所有你的電腦和網際網路之間的http通訊，設定斷點，檢視所有的"進出"Fiddler的資料(指cookie,html,js,css等檔案，這些都可以讓你胡亂修改的意思)。 Fiddler 要比其他的網路偵錯程式要更加簡單，因為它不僅僅暴露http通訊還提供了一個使用者友好的格式。---摘自《360百科》
Fiddler方便作為中間http代理伺服器擷取客戶端傳送的資料包。下面要做的是用用Fiddler抓取ios裝置中摩拜單車的單車資料以及API，截止到現在摩拜單車官方APi已經使用HTTPS進行通訊。下面從Fiddler安裝HTTPS證書到獲取API的過程。

• 1.安裝Fiddler4抓包工具
  • 因為官方軟體下載速度比較慢，所以在360軟體庫下載Fiddler安裝過程很簡單純粹下一步。

• 2.設定Fiddler抓取HTTPS資料包。
  • 1.安裝成功之後，啟動Fiddler進入軟體介面。

• 2. 選擇tools->options->https和tools->options->connections,然後按下圖紅線勾上和設定。

• 3.完成上述操作之後，要fiddler對ios裝置的https通訊轉包，還要下載https證書，fiddler預設的https證書對ios和android裝置不起作用。可能出現彈窗，安裝root certificate not successful。所以現在我們需要下載fiddlercertmaker來手動生成證書。雙擊之後，自動生成證書，然後重新啟動fiddler，下載如圖所示：

• 4.要抓取蘋果裝置的https資料包，必須使fiddler的PC和蘋果裝置處於同一區域網。小編選擇的是在PC上下載WIFI大師，然後用蘋果裝置連線上PC的WIFI熱點。在Fiddler中通過檢視PC本機的無線網路IP地址。如圖所所標誌的紅點，例如是192.168.144.1：

• 5.在蘋果裝置上連線上WIFI熱點，然後設定連線上的WIFI熱點的HTTP代理。伺服器填寫192.168.144.1(即是上一步驟的IP地址)，埠即是FIddler預設設定的8888如圖所示：

• 3.完成了上述安裝設定之後，FIddler便可以擷取裝置上的資料包。摩拜單車提供了APP和微信小程式的形式。接下來我們用Fiddler獲取摩拜單車小程式的資料包。啟動微信小程式摩拜單車，如下圖所示：

• 4.分析FIddler擷取到的https資料包，發現摩拜單車小程式返回json資料(自己特意跑到離自己最近的一輛單車判斷資料是否準確)

• 5.返回的資料格式如下所示：
