method Http2Stream.sendTrailers
Usage in Deno
```typescript import { type Http2Stream } from "node:node__http2.d.ts"; ```
Http2Stream.sendTrailers(headers: OutgoingHttpHeaders): void
Sends a trailing `HEADERS` frame to the connected HTTP/2 peer. This method
will cause the `Http2Stream` to be immediately closed and must only be
called after the `'wantTrailers'` event has been emitted. When sending a
request or sending a response, the `options.waitForTrailers` option must be set
in order to keep the `Http2Stream` open after the final `DATA` frame so that
trailers can be sent.
```js
import http2 from 'node:http2';
const server = http2.createServer();
server.on('stream', (stream) => {
stream.respond(undefined, { waitForTrailers: true });
stream.on('wantTrailers', () => {
stream.sendTrailers({ xyz: 'abc' });
});
stream.end('Hello World');
});
```
The HTTP/1 specification forbids trailers from containing HTTP/2 pseudo-header
fields (e.g. `':method'`, `':path'`, etc).
