php - Laravel CORS 进入框架 v 9

Question

在 Laravel 9 之前出现错误时:

Access to XMLHttpRequest at 'http://localhost:8000/demo' from origin 'null' 
has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is 
present on the requested resource.

我必须安装 fruitcake/laravel-cors ( https://www.positronx.io/how-to-enable-cors-in-laravel/ )。

在 Laravel 9 中我找到了资料:

"将 Laravel CORS 集成到框架中Dries Vints 将 fruitcake/laravel-cors 包迁移到 Laravel 框架中:主要原因是我们想要删除我们依赖的循环依赖，此外我们还需要删除骨架的另一个依赖。代码的所有学分归于@fruitcake 的@barryvdh。感谢您维护该软件包这么久!”。

我如何在新的 Laravel 中为 url: api/list 和 api/profiles 创建 cors？

Answer 1

在您的 app/Http/Kernel.php 中检查 CORS 中间件是否存在:

protected $middleware = [
    ...
    \Illuminate\Http\Middleware\HandleCors::class,
    ...
];

然后打开您的config/cors.php。它的工作原理与 fruitcake/laravel-cors 完全相同:

<?php

return [

    /*

    | Cross-Origin Resource Sharing (CORS) Configuration
    |--------------------------------------------------------------------------
    |
    | Here you may configure your settings for cross-origin resource sharing
    | or "CORS". This determines what cross-origin operations may execute
    | in web browsers. You are free to adjust these settings as needed.
