准备工作

Mac+iTunes+Charles(v3.11.4)
Charles需要安装Charles Root Certificate.
1.Charles下载证书*.pem
	Help->SSL Proxying->Save Charles Root Certificates...
2.钥匙串安装证书
	File->Import Items

步骤(以微信为例)

1.打开itunes和Charles，在iTunes中搜索微信，并点击Get按钮。

2.在Charles的请求列表中寻找形如https://*-buy.itunes.com(buyProduct.woa)等的请求，右键请求Enable SSL Proxying并打开Breakpoints.
3.从Charles捕获的2中buyProduct.woa的返回中查找softwareVersionExternalIdentifiers字段及其对应的列表Value.此列表代表的版本号从最早到最新排列。

4.在iTunes中删除先前下载好的包，并再次执行1，将会发现Charles断点执行到。编辑其中的appExtVrsId为3中的老版本的vrsId并点击Execute，可能需要在断点再次执行到时点击Execute。

5.在iTunes已安装的App中可以查找到需要的老版本的APP.
