**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).
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.
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`.
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).
**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).
`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.
Each error contains (if available) `statusCode`, `statusMessage`, `host`, `hostname`, `method`, `path`, `protocol` and `url` properties to make debugging easier.
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`
Requests to AWS services need to have their headers signed. This can be accomplished by using the [`aws4`](https://www.npmjs.com/package/aws4) package. This is an example for querying an ["Elasticsearch Service"](https://aws.amazon.com/elasticsearch-service/) host with a signed request.
```js
const url = require('url');
const AWS = require('aws-sdk');
const aws4 = require('aws4');
const got = require('got');
const config = require('./config');
// Reads keys from the environment or `~/.aws/credentials`. Could be a plain object.
const awsConfig = new AWS.Config({ region: config.region });
function request(uri, options) {
const awsOpts = {
region: awsConfig.region,
headers: {
accept: 'application/json',
'content-type': 'application/json'
},
method: 'GET',
json: true
};
// We need to parse the URL before passing it to `got` so `aws4` can sign the request
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.
Bear in mind, if you send an `if-modified-since` header and receive a `304 Not Modified` response, the body will be empty. It's your responsibility to cache and retrieve the body contents.
