### `url.urlToHttpOptions(url)`
<!-- YAML
added: REPLACEME
-->

* `url` {URL} The [WHATWG URL][] object to convert to an options object.
* Returns: {Object} Options object
jasnell marked this conversation as resolved.
Show resolved Hide resolved
* `protocol` {string} Protocol to use.
* `hostname` {string} A domain name or IP address of the server to issue the
request to.
* `hash` {string} The fragment portion of the URL.
* `search` {string} The serialized query portion of the URL.
* `pathname` {string} The path portion of the URL.
* `path` {string} Request path. Should include query string if any.
E.G. `'/index.html?page=12'`. An exception is thrown when the request path
contains illegal characters. Currently, only spaces are rejected but that
may change in the future.
* `href` {string} The serialized URL.
* `port` {number} Port of remote server.
* `auth` {string} Basic authentication i.e. `'user:password'` to compute an
Authorization header.

This utility function converts a URL object into an ordinary options object as
expected by the [`http.request()`][] and [`https.request()`][] APIs.

Sorry for intruding here - but just out of curiosity: what's urlToHttpOptions doing that you wouldn't get out of a URL already, exactly? Looks almost 1:1 to me.

> new URL('https://a:b@測試?abc#foo')
URL {
  href: 'https://a:b@xn--g6w251d/?abc#foo',
  origin: 'https://xn--g6w251d',
  protocol: 'https:',
  username: 'a',
  password: 'b',
  host: 'xn--g6w251d',
  hostname: 'xn--g6w251d',
  port: '',
  pathname: '/',
  search: '?abc',
  searchParams: URLSearchParams { 'abc' => '' },
  hash: '#foo'
}

URL does not have an auth option, port is a string (it should be a number or undefined), it doesn't have a path property. These options are used by the http module.

Thanks for the clarification 👍🏼. Exactly - that's why I was saying "almost 1:1". I mean,

function urlToHttpOptions(url) {
  return {
    ...url,
    auth: `${url.username}:${url.password}`.
    port: url.port === '' ? undefined : Number(url.port),
    path: `${url.pathname ?? ''}${url.search ?? ''}`
  }
}

Not 100%, but that's pretty much it, right?

EDIT
...ok, just checked the implementation myself and I think I can answer my own question.


console.log(urlToHttpOptions(myUrl));
/**
{
protocol: 'https:',
hostname: 'xn--g6w251d',
hash: '#foo',
search: '?abc',
pathname: '/',
path: '/?abc',
href: 'https://a:b@xn--g6w251d/?abc#foo',
auth: 'a:b'
}
*/
```
