抓包导出的har格式解析
使用Chrome开发者工具即Charles等抓包后可以到处.har格式的网络请求包，例如：打开Chrome浏览器打开开发者工具，切换到网络面板浏览器访问https://httpbin.org/get?a=1&b=2在开发者工具，网络面包点击导出图标，如下图：选择位置并保持，得到一个httpbin.org.har的文件。这个文件实际上是一个基于JSON格式的纯文本文件，可以使用记事本等打开。

使用Chrome开发者工具即Charles等抓包后可以到处.har格式的网络请求包，例如：
- 打开Chrome浏览器
- 打开开发者工具，切换到网络面板
- 浏览器访问https://httpbin.org/get?a=1&b=2
- 在开发者工具，网络面包点击导出图标，如下图：
选择位置并保持，得到一个httpbin.org.har的文件。
这个文件实际上是一个基于JSON格式的纯文本文件，可以使用记事本等打开。例如使用VsCode打开后，显示如下：

其基本格式如下：
log: 捕获的纪录，最外层
pages: 捕获的页面，每个页面有个页面id
entries: 捕获的所有接口
request: 接口中包含请求信息
response：接口中的响应信息
因此我们可以使用代码解析出其中的请求即请求数据、请求头等进行“重放”请求。
