# Class: ProxyAgent
|
|
|
|
Extends: `undici.Dispatcher`
|
|
|
|
A Proxy Agent class that implements the Agent API. It allows the connection through proxy in a simple way.
|
|
|
|
## `new ProxyAgent([options])`
|
|
|
|
Arguments:
|
|
|
|
* **options** `ProxyAgentOptions` (required) - It extends the `Agent` options.
|
|
|
|
Returns: `ProxyAgent`
|
|
|
|
### Parameter: `ProxyAgentOptions`
|
|
|
|
Extends: [`AgentOptions`](Agent.md#parameter-agentoptions)
|
|
|
|
* **uri** `string` (required) - It can be passed either by a string or a object containing `uri` as string.
|
|
* **token** `string` (optional) - It can be passed by a string of token for authentication.
|
|
* **auth** `string` (**deprecated**) - Use token.
|
|
* **clientFactory** `(origin: URL, opts: Object) => Dispatcher` (optional) - Default: `(origin, opts) => new Pool(origin, opts)`
|
|
* **requestTls** `BuildOptions` (optional) - Options object passed when creating the underlying socket via the connector builder for the request. See [TLS](https://nodejs.org/api/tls.html#tlsconnectoptions-callback).
|
|
* **proxyTls** `BuildOptions` (optional) - Options object passed when creating the underlying socket via the connector builder for the proxy server. See [TLS](https://nodejs.org/api/tls.html#tlsconnectoptions-callback).
|
|
|
|
Examples:
|
|
|
|
```js
|
|
import { ProxyAgent } from 'undici'
|
|
|
|
const proxyAgent = new ProxyAgent('my.proxy.server')
|
|
// or
|
|
const proxyAgent = new ProxyAgent({ uri: 'my.proxy.server' })
|
|
```
|
|
|
|
#### Example - Basic ProxyAgent instantiation
|
|
|
|
This will instantiate the ProxyAgent. It will not do anything until registered as the agent to use with requests.
|
|
|
|
```js
|
|
import { ProxyAgent } from 'undici'
|
|
|
|
const proxyAgent = new ProxyAgent('my.proxy.server')
|
|
```
|
|
|
|
#### Example - Basic Proxy Request with global agent dispatcher
|
|
|
|
```js
|
|
import { setGlobalDispatcher, request, ProxyAgent } from 'undici'
|
|
|
|
const proxyAgent = new ProxyAgent('my.proxy.server')
|
|
setGlobalDispatcher(proxyAgent)
|
|
|
|
const { statusCode, body } = await request('http://localhost:3000/foo')
|
|
|
|
console.log('response received', statusCode) // response received 200
|
|
|
|
for await (const data of body) {
|
|
console.log('data', data.toString('utf8')) // data foo
|
|
}
|
|
```
|
|
|
|
#### Example - Basic Proxy Request with local agent dispatcher
|
|
|
|
```js
|
|
import { ProxyAgent, request } from 'undici'
|
|
|
|
const proxyAgent = new ProxyAgent('my.proxy.server')
|
|
|
|
const {
|
|
statusCode,
|
|
body
|
|
} = await request('http://localhost:3000/foo', { dispatcher: proxyAgent })
|
|
|
|
console.log('response received', statusCode) // response received 200
|
|
|
|
for await (const data of body) {
|
|
console.log('data', data.toString('utf8')) // data foo
|
|
}
|
|
```
|
|
|
|
#### Example - Basic Proxy Request with authentication
|
|
|
|
```js
|
|
import { setGlobalDispatcher, request, ProxyAgent } from 'undici';
|
|
|
|
const proxyAgent = new ProxyAgent({
|
|
uri: 'my.proxy.server',
|
|
// token: 'Bearer xxxx'
|
|
token: `Basic ${Buffer.from('username:password').toString('base64')}`
|
|
});
|
|
setGlobalDispatcher(proxyAgent);
|
|
|
|
const { statusCode, body } = await request('http://localhost:3000/foo');
|
|
|
|
console.log('response received', statusCode); // response received 200
|
|
|
|
for await (const data of body) {
|
|
console.log('data', data.toString('utf8')); // data foo
|
|
}
|
|
```
|
|
|
|
### `ProxyAgent.close()`
|
|
|
|
Closes the proxy agent and waits for registered pools and clients to also close before resolving.
|
|
|
|
Returns: `Promise<void>`
|
|
|
|
#### Example - clean up after tests are complete
|
|
|
|
```js
|
|
import { ProxyAgent, setGlobalDispatcher } from 'undici'
|
|
|
|
const proxyAgent = new ProxyAgent('my.proxy.server')
|
|
setGlobalDispatcher(proxyAgent)
|
|
|
|
await proxyAgent.close()
|
|
```
|
|
|
|
### `ProxyAgent.dispatch(options, handlers)`
|
|
|
|
Implements [`Agent.dispatch(options, handlers)`](Agent.md#parameter-agentdispatchoptions).
|
|
|
|
### `ProxyAgent.request(options[, callback])`
|
|
|
|
See [`Dispatcher.request(options [, callback])`](Dispatcher.md#dispatcherrequestoptions-callback).
