method ServerHttp2Session.origin
Usage in Deno
```typescript import { type ServerHttp2Session } from "node:node__http2.d.ts"; ```
ServerHttp2Session.origin(...origins: Array<string
| url.URL
| { origin: string; }>): void
Submits an `ORIGIN` frame (as defined by [RFC 8336](https://tools.ietf.org/html/rfc8336)) to the connected client
to advertise the set of origins for which the server is capable of providing
authoritative responses.
```js
import http2 from 'node:http2';
const options = getSecureOptionsSomehow();
const server = http2.createSecureServer(options);
server.on('stream', (stream) => {
stream.respond();
stream.end('ok');
});
server.on('session', (session) => {
session.origin('https://example.com', 'https://example.org');
});
```
When a string is passed as an `origin`, it will be parsed as a URL and the
origin will be derived. For instance, the origin for the HTTP URL `'https://example.org/foo/bar'` is the ASCII string` 'https://example.org'`. An error will be thrown if either the given
string
cannot be parsed as a URL or if a valid origin cannot be derived.
A `URL` object, or any object with an `origin` property, may be passed as
an `origin`, in which case the value of the `origin` property will be
used. The value of the `origin` property _must_ be a properly serialized
ASCII origin.
Alternatively, the `origins` option may be used when creating a new HTTP/2
server using the `http2.createSecureServer()` method:
```js
import http2 from 'node:http2';
const options = getSecureOptionsSomehow();
options.origins = ['https://example.com', 'https://example.org'];
const server = http2.createSecureServer(options);
server.on('stream', (stream) => {
stream.respond();
stream.end('ok');
});
```
