Intercepts HTTPs Traffic with Python & mitmproxy

Introduction

Modern applications usually make use of back-end API servers to provide their services. With a non-transparent HTTPs proxy, which intercepts the communication between clients and servers (aka the man-in-the-middle scheme), you can easily manipulate both API requests and responses.

This manual helps you create your own proxy with Python and mitmproxy/libmproxy. Mitmproxy ships with both a standalone command-line tool (mitmproxy) and a Python library (libmproxy).

基本定制型
C.__init__(self[, arg1, ...]) 构造器（带一些可选的参数）
C.__new__(self[, arg1, ...]) 构造器（带一些可选的参数）；通常用在设置不变数据类型的子类。
C.__del__(self) 解构器
C.__str__(self) 可打印的字符输出；内建str()及print 语句
C.__repr__(self) 运行时的字符串输出；内建repr() 和‘‘ 操作符
C.__unicode__(self)b Unicode 字符串输出；内建unicode() 
 
C.__call__(self, *args) 表示可调用的实例
C.__nonzero__(self) 为object 定义False 值；内建bool() （从2.2 版开始）
