This module provides an http.Agent
implementation that connects to a specified
HTTP or HTTPS proxy server, and can be used with the built-in https
module.
Specifically, this Agent
implementation connects to an intermediary "proxy"
server and issues the CONNECT HTTP method, which tells the proxy to
open a direct TCP connection to the destination server.
Since this agent implements the CONNECT HTTP method, it also works with other protocols that use this method when connecting over proxies (i.e. WebSockets). See the "Examples" section below for more.
Install with npm
:
$ npm install https-proxy-agent
var url = require('url');
var https = require('https');
var HttpsProxyAgent = require('https-proxy-agent');
// HTTP/HTTPS proxy to connect to
var proxy = process.env.http_proxy || 'http://168.63.76.32:3128';
console.log('using proxy server %j', proxy);
// HTTPS endpoint for the proxy to connect to
var endpoint = process.argv[2] || 'https://graph.facebook.com/tootallnate';
console.log('attempting to GET %j', endpoint);
var options = url.parse(endpoint);
// create an instance of the `HttpsProxyAgent` class with the proxy server information
var agent = new HttpsProxyAgent(proxy);
options.agent = agent;
https.get(options, function (res) {
console.log('"response" event!', res.headers);
res.pipe(process.stdout);
});
var url = require('url');
var WebSocket = require('ws');
var HttpsProxyAgent = require('https-proxy-agent');
// HTTP/HTTPS proxy to connect to
var proxy = process.env.http_proxy || 'http://168.63.76.32:3128';
console.log('using proxy server %j', proxy);
// WebSocket endpoint for the proxy to connect to
var endpoint = process.argv[2] || 'ws://echo.websocket.org';
var parsed = url.parse(endpoint);
console.log('attempting to connect to WebSocket %j', endpoint);
// create an instance of the `HttpsProxyAgent` class with the proxy server information
var options = url.parse(proxy);
var agent = new HttpsProxyAgent(options);
// finally, initiate the WebSocket connection
var socket = new WebSocket(endpoint, { agent: agent });
socket.on('open', function () {
console.log('"open" event!');
socket.send('hello world');
});
socket.on('message', function (data, flags) {
console.log('"message" event! %j %j', data, flags);
socket.close();
});
The HttpsProxyAgent
class implements an http.Agent
subclass that connects
to the specified "HTTP(s) proxy server" in order to proxy HTTPS and/or WebSocket
requests. This is achieved by using the HTTP CONNECT
method.
The options
argument may either be a string URI of the proxy server to use, or an
"options" object with more specific properties:
host
- String - Proxy host to connect to (may use hostname
as well). Required.port
- Number - Proxy port to connect to. Required.protocol
- String - If https:
, then use TLS to connect to the proxy.headers
- Object - Additional HTTP headers to be sent on the HTTP CONNECT method.net.connect()
/tls.connect()
