App中的數據可以用網絡爬蟲抓取么

答案是完全肯定的：凡是可以看到的APP數據都可以抓取。

下面我就介紹下自己的學習經驗和一些方法吧 本篇適合有過web爬蟲基礎的程序猿看

沒有的的話學的可能會吃力一些

App接口爬取數據過程

• 使用抓包工具
• 手機使用代理，app所有請求通過抓包工具
• 獲得接口，分析接口
• 反編譯apk獲取key
• 突破反爬限制

需要的工具：

• 夜神模擬器
• Fiddler
• Pycharm

實現過程

首先下載夜神模擬器模擬手機也可以用真機，然后下載Fiddler抓取手機APP數據包，分析接口完成以后使用Python實現爬蟲程序

Fiddler安裝配置過程

第一步：下載神器Fiddler

Fiddler下載完成之后，傻瓜式的安裝一下！

第二步：設置Fiddler

打開Fiddler, Tools-> Fiddler Options (配置完后記得要重啟Fiddler)

選中"Decrpt HTTPS traffic", Fiddler就可以截獲HTTPS請求

選中"Allow remote computers to connect". 是允許別的機器把HTTP/HTTPS請求發送到Fiddler上來

記住這個端口號是:8888

夜神模擬器安裝配置過程

第一步:下載安裝

• 夜神模擬器下載完成之后，傻瓜式的安裝一下！

第二步:配置橋接 實現互通

• 首先將當前手機網絡橋接到本電腦網絡 實現互通

安裝完成橋接驅動后配置IP地址，要配成和本機互通的網段，配置完成后打開主機cmd終端ping通ok

第三步:配置代理

打開主機cmd

2、輸入ipconfig查看本機IP

3、配置代理

進入夜神模擬器–打開設置–打開WLAN

點擊修改網絡–配置代理 如下圖：

配置完后保存

到這里我們就設置好所有的值，下面就來測試一下，打開手機的超級課程表APP

4、在夜神模擬器上下載你想爬取得App使用Fiddler抓包分析api后使用python進行爬取就可以了
