|
||
|
|
|
||
|
|
A nicer interface to the built-in [`http`](http://nodejs.org/api/http.html) module.
|
||
|
|
|
||
|
|
It supports following redirects, promises, streams, retries, automagically handling gzip/deflate and some convenience options.
|
||
|
|
|
||
|
|
Created because [`request`](https://github.com/request/request) is bloated *(several megabytes!)*.

## Install
|
||
|
|
|
||
|
|
**WARNING: Node.js 4 or higher is required for got@6 and above.** For older Node.js versions use [got@5](https://github.com/sindresorhus/got/tree/v5.x).
|
||
|
|
|
||
|
|
```
|
||
|
|
$ npm install --save got
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
const fs = require('fs');
|
||
|
|
const got = require('got');
|
||
|
|
|
||
|
|
got('todomvc.com')
|
||
|
|
.then(response => {
|
||
|
|
console.log(response.body);
|
||
|
|
//=> '<!doctype html> ...'
|
||
|
|
})
|
||
|
|
.catch(error => {
|
||
|
|
console.log(error.response.body);
|
||
|
|
//=> 'Internal server error ...'
|
||
|
|
});
|
||
|
|
|
||
|
|
// Streams
|
||
|
|
got.stream('todomvc.com').pipe(fs.createWriteStream('index.html'));
|
||
|
|
|
||
|
|
// For POST, PUT and PATCH methods got.stream returns a WritableStream
|
||
|
|
fs.createReadStream('index.html').pipe(got.stream.post('todomvc.com'));
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
### API
|
||
|
|
|
||
|
|
It's a `GET` request by default, but can be changed in `options`.
|
||
|
|
|
||
|
|
#### got(url, [options])
|
||
|
|
|
||
|
|
Returns a Promise for a `response` object with a `body` property, a `url` property with the request URL or the final URL after redirects, and a `requestUrl` property with the original request URL.
|
||
|
|
|
||
|
|
##### url
|
||
|
|
|
||
|
|
Type: `string`, `object`
|
||
|
|
|
||
|
|
The URL to request or a [`http.request` options](https://nodejs.org/api/http.html#http_http_request_options_callback) object.
|
||
|
|
|
||
|
|
Properties from `options` will override properties in the parsed `url`.
|
||
|
|
|
||
|
|
##### options
|
||
|
|
|
||
|
|
Type: `object`
|
||
|
|
|
||
|
|
Any of the [`http.request`](http://nodejs.org/api/http.html#http_http_request_options_callback) options.
|
||
|
|
|
||
|
|
###### body
|
||
|
|
|
||
|
|
Type: `string`, `buffer`, `readableStream`, `object`
|
||
|
|
|
||
|
|
*This is mutually exclusive with stream mode.*
|
||
|
|
|
||
|
|
Body that will be sent with a `POST` request.
|
||
|
|
|
||
|
|
If present in `options` and `options.method` is not set, `options.method` will be set to `POST`.
|
||
|
|
|
||
|
|
If `content-length` or `transfer-encoding` is not set in `options.headers` and `body` is a string or buffer, `content-length` will be set to the body length.
|
||
|
|
|
||
|
|
If `body` is a plain object, it will be stringified with [`querystring.stringify`](https://nodejs.org/api/querystring.html#querystring_querystring_stringify_obj_sep_eq_options) and sent as `application/x-www-form-urlencoded`.
|
||
|
|
|
||
|
|
###### encoding
|
||
|
|
|
||
|
|
Type: `string`, `null`<br>
|
||
|
|
Default: `'utf8'`
|
||
|
|
|
||
|
|
Encoding to be used on `setEncoding` of the response data. If `null`, the body is returned as a Buffer.
|
||
|
|
|
||
|
|
###### json
|
||
|
|
|
||
|
|
Type: `boolean`<br>
|
||
|
|
Default: `false`
|
||
|
|
|
||
|
|
*This is mutually exclusive with stream mode.*
|
||
|
|
|
||
|
|
Parse response body with `JSON.parse` and set `accept` header to `application/json`.
|
||
|
|
|
||
|
|
###### query
|
||
|
|
|
||
|
|
Type: `string`, `object`<br>
|
||
|
|
|
||
|
|
Query string object that will be added to the request URL. This will override the query string in `url`.
|
||
|
|
|
||
|
|
###### timeout
|
||
|
|
|
||
|
|
Type: `number`, `object`
|
||
|
|
|
||
|
|
Milliseconds to wait for a server to send response headers before aborting request with `ETIMEDOUT` error.
|
||
|
|
|
||
|
|
Option accepts `object` with separate `connect` and `socket` fields for connection and socket inactivity timeouts.
|
||
|
|
|
||
|
|
###### retries
|
||
|
|
|
||
|
|
Type: `number`, `function`<br>
|
||
|
|
Default: `5`
|
||
|
|
|
||
|
|
Number of request retries when network errors happens. Delays between retries counts with function `1000 * Math.pow(2, retry) + Math.random() * 100`, where `retry` is attempt number (starts from 0).
|
||
|
|
|
||
|
|
Option accepts `function` with `retry` and `error` arguments. Function must return delay in milliseconds (`0` return value cancels retry).
|
||
|
|
|
||
|
|
**Note:** if `retries` is `number`, `ENOTFOUND` and `ENETUNREACH` error will not be retried (see full list in [`is-retry-allowed`](https://github.com/floatdrop/is-retry-allowed/blob/master/index.js#L12) module).
|
||
|
|
|
||
|
|
###### followRedirect
|
||
|
|
|
||
|
|
Type: `boolean`<br>
|
||
|
|
Default: `true`
|
||
|
|
|
||
|
|
Defines if redirect responses should be followed automatically.
|
||
|
|
|
||
|
|
|
||
|
|
#### Streams
|
||
|
|
|
||
|
|
#### got.stream(url, [options])
|
||
|
|
|
||
|
|
`stream` method will return Duplex stream with additional events:
|
||
|
|
|
||
|
|
##### .on('request', request)
|
||
|
|
|
||
|
|
`request` event to get the request object of the request.
|
||
|
|
|
||
|
|
**Tip**: You can use `request` event to abort request:
|
||
|
|
|
||
|
|
```js
|
||
|
|
got.stream('github.com')
|
||
|
|
.on('request', req => setTimeout(() => req.abort(), 50));
|
||
|
|
```
|
||
|
|
|
||
|
|
##### .on('response', response)
|
||
|
|
|
||
|
|
`response` event to get the response object of the final request.
|
||
|
|
|
||
|
|
##### .on('redirect', response, nextOptions)
|
||
|
|
|
||
|
|
`redirect` event to get the response object of a redirect. The second argument is options for the next request to the redirect location.
|
||
|
|
|
||
|
|
##### .on('error', error, body, response)
|
||
|
|
|
||
|
|
`error` event emitted in case of protocol error (like `ENOTFOUND` etc.) or status error (4xx or 5xx). The second argument is the body of the server response in case of status error. The third argument is response object.
|
||
|
|
|
||
|
|
#### got.get(url, [options])
|
||
|
|
#### got.post(url, [options])
|
||
|
|
#### got.put(url, [options])
|
||
|
|
#### got.patch(url, [options])
|
||
|
|
#### got.head(url, [options])
|
||
|
|
#### got.delete(url, [options])
|
||
|
|
|
||
|
|
Sets `options.method` to the method name and makes a request.
|
||
|
|
|
||
|
|
|
||
|
|
## Errors
|
||
|
|
|
||
|
|
Each error contains (if available) `statusCode`, `statusMessage`, `host`, `hostname`, `method` and `path` properties to make debugging easier.
|
||
|
|
|
||
|
|
In Promise mode, the `response` is attached to the error.
|
||
|
|
|
||
|
|
#### got.RequestError
|
||
|
|
|
||
|
|
When a request fails. Contains a `code` property with error class code, like `ECONNREFUSED`.
|
||
|
|
|
||
|
|
#### got.ReadError
|
||
|
|
|
||
|
|
When reading from response stream fails.
|
||
|
|
|
||
|
|
#### got.ParseError
|
||
|
|
|
||
|
|
When `json` option is enabled and `JSON.parse` fails.
|
||
|
|
|
||
|
|
#### got.HTTPError
|
||
|
|
|
||
|
|
When server response code is not 2xx. Contains `statusCode` and `statusMessage`.
|
||
|
|
|
||
|
|
#### got.MaxRedirectsError
|
||
|
|
|
||
|
|
When server redirects you more than 10 times.
|
||
|
|
|
||
|
|
|
||
|
|
## Proxies
|
||
|
|
|
||
|
|
You can use the [`tunnel`](https://github.com/koichik/node-tunnel) module with the `agent` option to work with proxies:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const got = require('got');
|
||
|
|
const tunnel = require('tunnel');
|
||
|
|
|
||
|
|
got('todomvc.com', {
|
||
|
|
agent: tunnel.httpOverHttp({
|
||
|
|
proxy: {
|
||
|
|
host: 'localhost'
|
||
|
|
}
|
||
|
|
})
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Cookies
|
||
|
|
|
||
|
|
You can use the [`cookie`](https://github.com/jshttp/cookie) module to include cookies in a request:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const got = require('got');
|
||
|
|
const cookie = require('cookie');
|
||
|
|
|
||
|
|
got('google.com', {
|
||
|
|
headers: {
|
||
|
|
cookie: cookie.serialize('foo', 'bar')
|
||
|
|
}
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Form data
|
||
|
|
|
||
|
|
You can use the [`form-data`](https://github.com/form-data/form-data) module to create POST request with form data:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const fs = require('fs');
|
||
|
|
const got = require('got');
|
||
|
|
const FormData = require('form-data');
|
||
|
|
const form = new FormData();
|
||
|
|
|
||
|
|
form.append('my_file', fs.createReadStream('/foo/bar.jpg'));
|
||
|
|
|
||
|
|
got.post('google.com', {
|
||
|
|
body: form
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## OAuth
|
||
|
|
|
||
|
|
You can use the [`oauth-1.0a`](https://github.com/ddo/oauth-1.0a) module to create a signed OAuth request:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const got = require('got');
|
||
|
|
const crypto = require('crypto');
|
||
|
|
const OAuth = require('oauth-1.0a');
|
||
|
|
|
||
|
|
const oauth = OAuth({
|
||
|
|
consumer: {
|
||
|
|
key: process.env.CONSUMER_KEY,
|
||
|
|
secret: process.env.CONSUMER_SECRET
|
||
|
|
},
|
||
|
|
signature_method: 'HMAC-SHA1',
|
||
|
|
hash_function: (baseString, key) => crypto.createHmac('sha1', key).update(baseString).digest('base64')
|
||
|
|
});
|
||
|
|
|
||
|
|
const token = {
|
||
|
|
key: process.env.ACCESS_TOKEN,
|
||
|
|
secret: process.env.ACCESS_TOKEN_SECRET
|
||
|
|
};
|
||
|
|
|
||
|
|
const url = 'https://api.twitter.com/1.1/statuses/home_timeline.json';
|
||
|
|
|
||
|
|
got(url, {
|
||
|
|
headers: oauth.toHeader(oauth.authorize({url, method: 'GET'}, token)),
|
||
|
|
json: true
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Unix Domain Sockets
|
||
|
|
|
||
|
|
Requests can also be sent via [unix domain sockets](http://serverfault.com/questions/124517/whats-the-difference-between-unix-socket-and-tcp-ip-socket). Use the following URL scheme: `PROTOCOL://unix:SOCKET:PATH`.
|
||
|
|
|
||
|
|
- `PROTOCOL` - `http` or `https` *(optional)*
|
||
|
|
- `SOCKET` - absolute path to a unix domain socket, e.g. `/var/run/docker.sock`
|
||
|
|
- `PATH` - request path, e.g. `/v2/keys`
|
||
|
|
|
||
|
|
```js
|
||
|
|
got('http://unix:/var/run/docker.sock:/containers/json');
|
||
|
|
|
||
|
|
// or without protocol (http by default)
|
||
|
|
got('unix:/var/run/docker.sock:/containers/json');
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Tip
|
||
|
|
|
||
|
|
It's a good idea to set the `'user-agent'` header so the provider can more easily see how their resource is used. By default, it's the URL to this repo.
|
||
|
|
|
||
|
|
```js
|
||
|
|
const got = require('got');
|
||
|
|
const pkg = require('./package.json');
|
||
|
|
|
||
|
|
got('todomvc.com', {
|
||
|
|
headers: {
|
||
|
|
'user-agent': `my-module/${pkg.version} (https://github.com/username/my-module)`
|
||
|
|
}
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
