You can use the built-in [`useRequestHeader`](/docs/api/composables/use-request-header) composable to access any incoming request header within your pages, components, and plugins.
|
||
|
|
|
||
|
|
```ts
|
||
|
|
// Get the authorization request header
|
||
|
|
const authorization = useRequestHeader('authorization')
|
||
|
|
```
|
||
|
|
|
||
|
|
::callout
|
||
|
|
In the browser, `useRequestHeader` will return `undefined`.

## Example
|
||
|
|
|
||
|
|
We can use `useRequestHeader` to easily figure out if a user is authorized or not.
|
||
|
|
|
||
|
|
The example below reads the `authorization` request header to find out if a person can access a restricted resource.
|
||
|
|
|
||
|
|
```ts [middleware/authorized-only.ts]
|
||
|
|
export default defineNuxtRouteMiddleware((to, from) => {
|
||
|
|
if (!useRequestHeader('authorization')) {
|
||
|
|
return navigateTo('/not-authorized')
|
||
|
|
}
|
||
|
|
})
|
||
|
|
```
