我有一个使用 Laravel Inertia 和 Vue Js 的项目。这些天我遇到了 csrf 令牌的问题。我已经阅读了这里的文档 https://inertiajs.com/csrf-protection，所以也许我应该在每个惯性请求/响应上添加 csrf 令牌。

我的问题是，如何全局添加这个_token？所以我不需要一一添加token到我的vue文件中，因为它的文件太多了。

我当前在login.vue上的脚本代码：

props: {
        errors: Object,
        session: Object,
        auth: Array
    },

    //define composition API
    setup(props) {
        //define form state
        const form = reactive({
            email: '',
            password: '',
        });

        //submit method
        const submit = () => {

            //send data to server
            Inertia.post('/login', {

                //data
                email: form.email,
                password: form.password,
                _token: props.auth.csrf
            });
        }

我的 HandleInertiaRequest（中间件）：

<?php

namespace AppHttpMiddleware;

use IlluminateHttpRequest;
use InertiaMiddleware;

class HandleInertiaRequests extends Middleware
{
    /**
     * The root template that's loaded on the first page visit.
     *
     * @see https://inertiajs.com/server-side-setup#root-template
     * @var string
     */
    protected $rootView = 'app';

    /**
     * Determines the current asset version.
     *
     * @see https://inertiajs.com/asset-versioning
     * @param  IlluminateHttpRequest  $request
     * @return string|null
     */
    public function version(Request $request): ?string
    {
        return parent::version($request);
    }

    /**
     * Defines the props that are shared by default.
     *
     * @see https://inertiajs.com/shared-data
     * @param  IlluminateHttpRequest  $request
     * @return array
     */
    public function share(Request $request): array
    {
        return array_merge(parent::share($request), [
            //session
            'session' => [
                'status'    => fn () => $request->session()->get('status'),
                'success'   => fn () => $request->session()->get('success'),
                'error'     => fn () => $request->session()->get('error'),
            ],
            //user authenticated
            'auth' => [
                'user'          => $request->user() ?   $request->user() : null,
                'permissions'   => $request->user() ? $request->user()->getPermissionArray() : [],
                'csrf' => $request->session()->token()
            ],
            //route
            'route' => function () use ($request) {
                return [
                    'params' => $request->route()->parameters(),
                    'query' => $request->all(),
                ];
            },
        ]);
    }
}
