Vue 3 - Add Bearer Token Authorization Header to HTTP Request
Below is a quick example of how to add a Bearer Token Authorization Header to an HTTP request in Vue 3 using fetch() which comes built into all modern browsers.
Vue 3 Bearer Token
This sends an HTTP GET request to the Test JSON API with a couple of headers, the HTTP Authorization header with a bearer token and a custom header My-Custom-Header. The Test JSON API is a fake online REST API that includes a product details route (/products/{id}), the returned product includes an id and name.
After the JSON data is fetched from the API it is assigned to the product ref variable and rendered in the component template.
Add Authorization Header
The auth header with bearer token is added to the request by passing a custom headers object (e.g. { headers: { 'Authorization': 'Bearer my-token' } }) as the second parameter to the fetch() function. The second param contains the fetch request options and it supports a bunch of different options for making HTTP requests including setting headers, a complete list is available at https://developer.mozilla.org/docs/Web/API/fetch.
<script setup>
import { ref } from 'vue';
const product = ref(null);
// GET request using fetch with set headers
const headers = {
'Authorization': 'Bearer my-token',
'My-Custom-Header': 'foobar'
};
fetch('https://testapi.jasonwatmore.com/products/3', { headers })
.then(response => response.json())
.then(data => product.value = data);
</script>
<template>
<div class="card text-center m-3">
<h5 class="card-header">GET Request with Set Headers</h5>
<div class="card-body">Product name: {{product?.name}}</div>
</div>
</template>
