一个基于nodejs的超级简单的http proxy程序

root@AR:~# proxy
HTTP(s) proxy server listening on port 3128
^C
root@AR:~# nohup proxy > /dev/null &
[1] 21563
root@AR:~# nohup: 忽略输入重定向错误到标准输出端

root@AR:~# 
root@AR:~# proxy -h

  Usage: proxy [options]

  Options:

    -h, --help                    output usage information
    -V, --version                 output the version number
    -p, --port <n>                TCP port number to bind to. Defaults to 3128
    -a, --authenticate <command>  "authenticate" command to run when "Proxy-Authorization" is given

root@AR:~# nohup proxy -p some_port > /dev/null & (需回车2次)


已测试过,可用作tor的前置代理,从而使得tor browser成功连上tor网络。

proxy

An HTTP proxy written with Node.js (think Squid)

Build Status
This module provides standard "HTTP proxy" logic. You can script your own server using the proxy server API. Be sure to take a look at the "Examples" section below.
There is also a companion proxy(1) CLI tool, which spawns an HTTP(s) proxy server with the specified options.
You could think of proxy(1) as similar to some of the other popular open source HTTP proxy software:

Installation

Install with npm:
$ npm install proxy
If you would like to have the proxy(1) CLI program in your $PATH, then install "globally":
$ npm install -g proxy

Examples

Basic HTTP(s) proxy server

A basic HTTP(s) server with all the default options. All requests are allowed. CONNECT HTTP method works as well.
var http = require('http');
var setup = require('proxy');

var server = setup(http.createServer());
server.listen(3128, function () {
  var port = server.address().port;
  console.log('HTTP(s) proxy server listening on port %d', port);
});

CLI Tool Examples

The proxy(1) CLI tool can be used to spawn HTTP(s) proxy server instances with various options.

Port to bind to

Pass the -p/--port option to with a port number to specify a TCP port to bind to. Defaults to 3128 if none is specified.
$ proxy --port 8080

Custom Proxy-Authenticate command

Pass the -a/--authenticate switch with a command to execute when the client Proxy-Authorization header is given. This command determines whether or not the request is authorized based on the "exit code" of the command.
The relevant request authentication information is passed in as PROXY_AUTH_USERNAMEPROXY_AUTH_PASSWORD and PROXY_AUTH_SCHEME environment variables.
For example, to authorize "Basic" authentication with username "foo" and password "bar":
$ proxy --authenticate 'if \
    [ "$PROXY_AUTH_USERNAME" = "foo" ] && \
    [ "$PROXY_AUTH_PASSWORD" = "bar" ]; \
      then exit 0; \
    fi; \
    exit 1;'
