Laravel Sanctum：使用 Nuxt Auth 模块被 CORS 策略阻止

Question

我有一个由 Valet on backend.test and a Nuxt SPA on nuxt.backend.test:3005. When I try to authenticate to Sanctum with Nuxt Auth 模块提供服务的 Laravel 网站，我收到以下 CORS 错误：

Access to XMLHttpRequest at 'http://backend.test/login' from origin 'http://nuxt.backend.test:3005' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

我该如何解决？

Laravel配置

config/cors.php:

<?php

return [
    'paths' => ['*'],
    'allowed_methods' => ['*'],
    'allowed_origins' => ['*'],
    'allowed_origins_patterns' => [],
    'allowed_headers' => ['*'],
    'exposed_headers' => [],
    'max_age' => 0,
    'supports_credentials' => true,
];

routes/api.php:

Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
    return $request->user();
});

app/Http/Kernel.php:

    protected $middlewareGroups = [
        ...
        'api' => [
            EnsureFrontendRequestsAreStateful::class,
            'throttle:60,1',
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],
    ];

.env:

SANCTUM_STATEFUL_DOMAINS="backend.test"
SESSION_DOMAIN=".backend.test"

Nuxt 配置 nuxt.config.js:

export default {
  server: {
    port: '3005',
    host: 'nuxt.backend.test'
  },
  ...
  modules: [
    '@nuxtjs/axios',
    '@nuxtjs/auth-next'
  ],
  axios: {
    proxy: true
  },
  proxy: {
    '/nuxt': {
      target: 'nuxt.backend.test',
      pathRewrite: { '^/nuxt': '/' }
    }
  },
  auth: {
    redirect: {
      callback: '/auth/callback'
    },
    strategies: {
      laravelSanctum: {
        provider: 'laravel/sanctum',
        url: 'http://backend.test'
      }
    }
  },
  ...
}

pages/index.php:

<template>
  <div>
    <div>
      <pre>{{ $auth.user }}</pre>
    </div>
    <button @click="signIn()">Sign in</button>
  </div>
</template>

<script>
export default {
  methods: {
    signIn() {
      this.$auth.loginWith('laravelSanctum', {
        data: {
          email: 'me@home.com',
          password: '1qaz@WSX'
        }
      })
    }
  }
}
</script>

Laravel 后端和 Nuxt 前端必须在同一个域下，所以我最终通过 3 个步骤修复了它:

1。将此添加到 /etc/hosts:

127.0.0.1   nuxt.backend.test

2。使用测试版 @nuxt/auth:

npm remove @nuxtjs/auth
npm install @nuxtjs/auth-next @nuxtjs/axios

在nuxt.config.js中，使用：

  modules: [
    '@nuxtjs/axios',
    '@nuxtjs/auth-next'
  ],

3。使用以下配置：

{
  axios: {
    proxy: true
  },
  proxy: {
    '/laravel': {
      target: 'http://backend.test',
      pathRewrite: { '^/laravel': '/' }
    }
  },
  auth: {
    strategies: {
      laravelSanctum: {
        provider: 'laravel/sanctum',
        url: '/laravel'
      }
    }
  }
}

或者，用 localhost 替换 backend.test 和 nuxt.backend.test，并从 nuxt.config.js 中删除 Nuxt 服务器 host然后使用 php artisan serve 而不是 Valet 因为 Laravel 也可以。
