Browser automation frameworks–like Puppeteer, Selenium, Marionette, and Nightmare.js–strive to provide rich APIs for configuring and interacting with Web browsers. These generally work quite well, but you’re inevitably going to end up running into API limitations if you do a lot of testing or Web scraping. You might find yourself wanting to conceal the fact that you’re using a headless browser, extract image resources from a Web page, set the seed for Math.random(), or mock the browser’s geolocation before running your test suite. Your specific automation framework might provide a built-in way to accomplish some of these, but they all have their limitations.

mitmproxy 是一个支持 HTTP 和 HTTPS 的抓包程序，有类似 Fiddler、Charles 的功能，只不过它是一个控制台的形式操作。

mitmproxy 还有两个关联组件。一个是 mitmdump，它是 mitmproxy 的命令行接口，利用它我们可以对接 Python 脚本，用 Python 实现监听后的处理。另一个是 mitmweb，它是一个 Web 程序，通过它我们可以清楚观察 mitmproxy 捕获的请求。
