How to add token when using axios to send an ajax request? - ajax

Question

I am using Laravel 5.3 and vue.js 2.0，
And I use axios (https://github.com/mzabriskie/axios) to send ajax requests,
I follow the docs to set the TOKEN like this:
<script>
axios.defaults.headers.common['Authorization'] = AUTH_TOKEN; //The error is at this line.
new Vue({
el: "#app",
data: function () {
return {
items: []
}
},
mounted: function () {
this.$nextTick(function () {
axios.get('/articles').then(function (response) {
response.data.forEach(function (item) {
item.selected = false;
});
this.items = response.data;
}).catch(function (error) {
console.log(error);
});
});
}
});
</script>
the error in console is like this:
Uncaught ReferenceError: AUTH_TOKEN is not defined
What should I do?

Answer 1

have you set AUTH_TOKEN on the window? If not window.AUTH_TOKEN will naturally not be defined.
A common set up in the head of a laravel app is:
<script>
window.Laravel = <?php echo json_encode([
'csrfToken' => csrf_token(),
]); ?>
</script>
This would therefore set the csrf token. I wouldn't imagine this is how you'll be setting an Auth token so you'll probably just need to look into why you are calling window.AUTH_TOKEN
In terms of how you generate your token that is dependant on what type you require but once you have it you may want to look instead at vuex for storing it. Doing so will allow you access to it throughout your app, without having to store anything on the window.

Answer 2

it should be
axios.defaults.headers.common['X-CSRF-TOKEN'] = document.querySelector('meta[name="csrf-token"]').getAttribute('content')
and you can remove the
<script>
window.Laravel = <?php echo json_encode([
'csrfToken' => csrf_token(),
]); ?>
</script>
