https-proxy-agent

================
|
|
### An HTTP(s) proxy `http.Agent` implementation for HTTPS
|
|
|
|
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][CONNECT], 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.

Examples
|
|
--------
|
|
|
|
#### `https` module example
|
|
|
|
```ts
|
|
import * as https from 'https';
|
|
import { HttpsProxyAgent } from 'https-proxy-agent';
|
|
|
|
const agent = new HttpsProxyAgent('http://168.63.76.32:3128');
|
|
|
|
https.get('https://example.com', { agent }, (res) => {
|
|
console.log('"response" event!', res.headers);
|
|
res.pipe(process.stdout);
|
|
});
|
|
```
|
|
|
|
#### `ws` WebSocket connection example
|
|
|
|
```ts
|
|
import WebSocket from 'ws';
|
|
import { HttpsProxyAgent } from 'https-proxy-agent';
|
|
|
|
const agent = new HttpsProxyAgent('http://168.63.76.32:3128');
|
|
const socket = new WebSocket('ws://echo.websocket.org', { 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();
|
|
});
|
|
```

### new HttpsProxyAgent(proxy: string | URL, options?: HttpsProxyAgentOptions)
|
|
|
|
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][CONNECT].
|
|
|
|
The `proxy` argument is the URL for the proxy server.
|
|
|
|
The `options` argument accepts the usual `http.Agent` constructor options, and
|
|
some additional properties:
|
|
|
|
* `headers` - Object containing additional headers to send to the proxy server
|
|
in the `CONNECT` request.
