使用python抓取App数据

App接口爬取数据过程
使用抓包工具
手机使用代理，app所有请求通过抓包工具
获得接口，分析接口
反编译apk获取key
突破反爬限制
需要的工具：
夜神模拟器
Fiddler
Pycharm
实现过程
首先下载夜神模拟器模拟手机也可以用真机，然后下载Fiddler抓取手机APP数据包，分析接口完成以后使用Python实现爬虫程序

Fiddler安装配置过程
第一步：下载神器Fiddler
Fiddler下载完成之后，傻瓜式的安装一下！

第二步：设置Fiddler
打开Fiddler, Tools-> Fiddler Options (配置完后记得要重启Fiddler)
选中”Decrpt HTTPS traffic”, Fiddler就可以截获HTTPS请求
选中”Allow remote computers to connect”. 是允许别的机器把HTTP/HTTPS请求发送到Fiddler上来

记住这个端口号是:8888

夜神模拟器安装配置过程

第一步:下载安装

夜神模拟器下载完成之后，傻瓜式的安装一下！

第二步:配置桥接实现互通

首先将当前手机网络桥接到本电脑网络实现互通

安装完成桥接驱动后配置IP地址，要配成和本机互通的网段，配置完成后打开主机cmd终端ping通ok

第三步:配置代理

打开主机cmd

输入ipconfig查看本机IP
配置代理
进入夜神模拟器–打开设置–打开WLAN
点击修改网络–配置代理如下图：

配置完后保存
到这里我们就设置好所有的值，下面就来测试一下，打开手机的超级课程表APP
1. 在夜神模拟器上下载你想爬取得App使用Fiddler抓包分析api后使用python进行爬取就可以了
爬取充电网APP实例
