Feature

work as http or https proxy
fully configurable, you could modify a request at any stage with your customized javascript code
when working as https proxy, AnyProxy could intercept https requests for any domain without complaint by browser (after you trust its root CA)
a web interface for you to watch realtime request details, where html with (almost) any charset could be shown correctly

Quick Start

step 1 - install

install NodeJS
npm install -g anyproxy , may require sudo
python is optional, it will be OK if you get some error about it during installing.

step 2 - start proxy server

start with default settings : anyproxy
...or start with a specific port: anyproxy --port 8001
...start with a rule file: anyproxy --rule ./rule_sample/rule_allow_CORS.js

step 3 - set up proxy settings in your browser , or system ,or mobile devices ,etc

default proxy should be 127.0.0.1:8001 , or you_ip_address:8001 on remote devices

step 4 - launch web interface

visit http://127.0.0.1:8002 ,you will see realtime requests in your browser
be sure to use web interface with modern browsers

Rule module

Rule module is the specialty for AnyProxy. Think it as a middleware, you could write your own code to hack requests at any stage, no matter it is about to response or the proxy just gets the request. In this way, AnyProxy would be flexible to meet your own demands.
It's highly recommended to read this guide before using: What is rule file and how to write one ?
An entire scheme of rule file could be found at ./rule_sample/rule__blank.js. Besides, there are some samples at ./rule_sample. That may help you a lot when writing your own rule files.

Https features

After configuring rootCA, AnyProxy could help to decrypt https requests, whose approach is also called Man-In-The-Middle(MITM).

A guide about configuring https features is here : https://github.com/alibaba/anyproxy/wiki/How-to-config-https-proxy

Others

to save request data

to save request data to local file, use anyproxy --file /path/to/file
anyproxy uses nedb to save request data. Since NeDB's persistence uses an append-only format, you may get some redundant record in local file. For those dupplicated ones with the same id, just use the lastest line of record.
TrafficeRecorder is another tool based on anyproxy to help recording all request data, including header and body. You may have a try.

throttling

for instance, anyproxy --throttle 10 sets the speed limit to 10kb/s (kbyte/sec)
this is just a rough throttling for downstream, not for network simulation

work as a module for nodejs

use it as a module and develop your own proxy.

npm install anyproxy --save

var proxy = require("anyproxy");

//create cert when you want to use https features
//please manually trust this rootCA when it is the first time you run it
!proxy.isRootCAFileExists() && proxy.generateRootCA();

var options = {
    type          : "http",
    port          : 8001,
    hostname      : "localhost",
    rule          : require("path/to/my/ruleModule.js"),
    dbFile        : null,  // optional, save request data to a specified file, will use in-memory db if not specified
    webPort       : 8002,  // optional, port for web interface
    socketPort    : 8003,  // optional, internal port for web socket, replace this when it is conflict with your own service
    throttle      : 10,    // optional, speed limit in kb/s
    disableWebInterface : false, //optional, set it when you don't want to use the web interface
    silent        : false //optional, do not print anything into terminal. do not set it when you are still debugging.
    rootCaDir     : __dirname + "/anyproxy/rootCa" //optional, your CA file dir.
};
new proxy.proxyServer(options);
