Instead, use [`stream.pipeline(from, ..., to, callback)`](https://nodejs.org/api/stream.html#stream_stream_pipeline_streams_callback). **Note:** While `got.post('https://example.com')` resolves, `got.stream.post('https://example.com')` will hang indefinitely until a body is provided. If there's no body on purpose, remember to `.end()` the stream or set the [`body`](#body) option to an empty string. ### API It's a `GET` request by default, but can be changed by using different methods or via [`options.method`](#method). **By default, Got will retry on failure. To disable this option, set [`options.retry`](#retry) to `0`.** #### got(url?, options?) Returns a Promise giving a [Response object](#response) or a [Got Stream](#streams-1) if `options.isStream` is set to true. ##### url Type: `string | object` The URL to request, as a string, a [`https.request` options object](https://nodejs.org/api/https.html#https_https_request_options_callback), or a [WHATWG `URL`](https://nodejs.org/api/url.html#url_class_url). Properties from `options` will override properties in the parsed `url`. If no protocol is specified, it will throw a `TypeError`. **Note:** The query string is **not** parsed as search params. Example: ```js got('https://example.com/?query=a b'); //=> https://example.com/?query=a%20b got('https://example.com/', {searchParams: {query: 'a b'}}); //=> https://example.com/?query=a+b // The query string is overridden by `searchParams` got('https://example.com/?query=a b', {searchParams: {query: 'a b'}}); //=> https://example.com/?query=a+b ``` ##### options Type: `object` Any of the [`https.request`](https://nodejs.org/api/https.html#https_https_request_options_callback) options. **Note:** Legacy URL support is disabled. `options.path` is supported only for backwards compatibility. Use `options.pathname` and `options.searchParams` instead. `options.auth` has been replaced with `options.username` & `options.password`. ###### method Type: `string`\ Default: `GET` The HTTP method used to make the request. ###### prefixUrl Type: `string | URL` When specified, `prefixUrl` will be prepended to `url`. The prefix can be any valid URL, either relative or absolute.\ A trailing slash `/` is optional - one will be added automatically. **Note:** `prefixUrl` will be ignored if the `url` argument is a URL instance. **Note:** Leading slashes in `input` are disallowed when using this option to enforce consistency and avoid confusion. For example, when the prefix URL is `https://example.com/foo` and the input is `/bar`, there's ambiguity whether the resulting URL would become `https://example.com/foo/bar` or `https://example.com/bar`. The latter is used by browsers. **Tip:** Useful when used with [`got.extend()`](#custom-endpoints) to create niche-specific Got instances. **Tip:** You can change `prefixUrl` using hooks as long as the URL still includes the `prefixUrl`. If the URL doesn't include it anymore, it will throw. ```js const got=require('got'); (async ()=> { await got('unicorn', {prefixUrl: 'https://cats.com'}); //=> 'https://cats.com/unicorn' const instance=got.extend({ prefixUrl: 'https://google.com' }); await instance('unicorn', { hooks: { beforeRequest: [ options=> { options.prefixUrl='https://cats.com'; } ] } }); //=> 'https://cats.com/unicorn' })(); ``` ###### headers Type: `object`\ Default: `{}` Request headers. Existing headers will be overwritten. Headers set to `undefined` will be omitted. ###### isStream Type: `boolean`\ Default: `false` Returns a `Stream` instead of a `Promise`. This is equivalent to calling `got.stream(url, options?)`. ###### body Type: `string | Buffer | stream.Readable` or [`form-data` instance](https://github.com/form-data/form-data) **Note #1:** The `body` option cannot be used with the `json` or `form` option. **Note #2:** If you provide this option, `got.stream()` will be read-only. **Note #3:** If you provide a payload with the `GET` or `HEAD` method, it will throw a `TypeError` unless the method is `GET` and the `allowGetBody` option is set to `true`. **Note #4:** This option is not enumerable and will not be merged with the instance defaults. The `content-length` header will be automatically set if `body` is a `string` / `Buffer` / `fs.createReadStream` instance / [`form-data` instance](https://github.com/form-data/form-data), and `content-length` and `transfer-encoding` are not manually set in `options.headers`. ###### json Type: `object | Array | number | string | boolean | null` *(JSON-serializable values)* **Note #1:** If you provide thi
