有时候报错就会跨域 抛出错误之后走错误处理就不会走允许跨域中间件了

使用laravel-cors依赖并且在app\Http\Middleware\VerifyCsrfToken文件中修改如下：

<?php

namespace App\Http\Middleware;

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as Middleware;

class VerifyCsrfToken extends Middleware
{
    /**
     * Indicates whether the XSRF-TOKEN cookie should be set on the response.
     *
     * @var bool
     */
    protected $addHttpCookie = true;

    /**
     * The URIs that should be excluded from CSRF verification.
     *
     * @var array
     */
    protected $except = [
        '*'
    ];
}

跨域如果使用nginx解决, 在Laravel中就不要添加, 防止http 响应头冲突
