You can use `useRequestFetch` to forward the request context and headers when making server-side fetch requests.
|
|
|
|
When making a client-side fetch request, the browser automatically sends the necessary headers.
|
|
However, when making a request during server-side rendering, because the request is made on the server, we need to forward the headers manually.
|
|
|
|
::note
|
|
Headers that are **not meant to be forwarded** will **not be included** in the request. These headers include, for example:
|
|
`transfer-encoding`, `connection`, `keep-alive`, `upgrade`, `expect`, `host`, `accept`
|
|

|
|
|
|
::tip
|
|
The [`useFetch`](/docs/api/composables/use-fetch) composable uses `useRequestFetch` under the hood to automatically forward the request context and headers.

```vue [pages/index.vue]
|
|
<script setup lang="ts">
|
|
// This will forward the user's headers to the `/api/foo` event handler
|
|
// Result: { cookies: { foo: 'bar' } }
|
|
const requestFetch = useRequestFetch()
|
|
const { data: forwarded } = await useAsyncData(() => requestFetch('/api/cookies'))
|
|
|
|
// This will NOT forward anything
|
|
// Result: { cookies: {} }
|
|
const { data: notForwarded } = await useAsyncData(() => $fetch('/api/cookies'))
|
|
</script>
|
|
```
|
|
|
|
```ts [server/api/cookies.ts]
|
|
export default defineEventHandler((event) => {
|
|
const cookies = parseCookies(event)
|
|
|
|
return { cookies }
|
|
})
|
|
```

::tip
|
|
In the browser during client-side navigation, `useRequestFetch` will behave just like regular [`$fetch`](/docs/api/utils/dollarfetch).
