如何在Laravel 5.8中启用CORS？

Question

我在Laravel 5.8中-我一直收到这个CORS问题

我尝试过

Http failure during parsing for http://localhost:8080/api/get/pdf

添加这些代码

php artisan make:middleware Cors

重新启动本地Apache 2 <?php namespace App\Http\Middleware; use Closure; class Cors { public function handle($request, Closure $next) { return $next($request) ->header(‘Access-Control-Allow-Origin’, ‘*’) ->header(‘Access-Control-Allow-Methods’, ‘GET, POST, PUT, DELETE, OPTIONS’) ->header(‘Access-Control-Allow-Headers’, ‘X-Requested-With, Content-Type, X-Token-Auth, Authorization’); } }

打开sudo apachectl -k restart-添加了这1行

app/Http/Kernel.php

刷新站点，转到控制台，仍然看到相同的CORS问题

人们将如何进行进一步的调试？

Answer 1

第一个解决方案

尝试将CORS中间件设置为全局中间件。

handle function中的CORS middleware：

 public function handle($request, Closure $next)
 {
  return $next($request)
   ->header('Access-Control-Allow-Origin', '*')
   ->header('Access-Control-Allow-Methods', 'GET', 'POST', 'PUT', 'PATCH', 'DELETE', 'OPTIONS')
   ->header('Access-Control-Allow-Headers', 'Content-Type, Authorization');
 }

要全局添加此中间件，请转到App\Http\Kernel，然后在$middleware数组中添加以下行：

\App\Http\Middleware\Cors::class,

第二个解决方案

您还可以在bootstrap/app.php

中添加此代码

header('Access-Control-Allow-Origin', '*');
header('Access-Control-Allow-Methods', 'GET', 'POST', 'PUT', 'PATCH', 'DELETE', 'OPTIONS');
header('Access-Control-Allow-Headers', 'Content-Type, Authorization');

希望它能起作用！

Answer 2

尝试使用laravel-cors软件包，该软件包可让您使用Laravel中间件配置发送跨域资源共享标头。

Answer 3

在下面向您添加.htaccess（只需添加到目标站点和原始站点）

Header always set Access-Control-Allow-Origin "*"
Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
Header always set Access-Control-Max-Age "1000"
Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"

RewriteEngine On
RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ $1 [R=200,L]

希望它可以节省人的时间，快乐的编码！！！
