Question

我跟着this post但它只适用于GET方法（正如你可以看到它在评论中提到）。我还安装了this pakage，但它只适用于GET方法。这是我得到的错误：

否＆＃39;访问控制 - 允许 - 来源＆＃39;标头出现在请求的资源上。因此，不允许访问来源 我的来源 。响应的HTTP状态代码为403。

PHP版本：7.1

Laravel版本：5.6

Answer 1

你也可以使用barryvdh的伟大laravel-cors包。

安装软件包之后，获得所有路由的CORS支持的最简单方法是在Http / Kernel.php中添加这样的中间件：（$ middleware）

^\w*[aeiouy]\w*[aeiouy]\w*(?!([aeiouy]+))

并修改\Barryvdh\Cors\HandleCors::class config/Cors.php

Answer 2

您需要不使用任何程序包而使用第一种方法this post，然后像this post一样将此类添加到protected $middleware中，然后post方法也具有所需的标题。

对我有用，希望对您有用。

Answer 3

不需要laravel-cors的任何类型的软件包。只需创建中间件：

namespace App\Http\Middleware;
use Closure;
class Cors {

    public function handle($request, Closure $next) {
        $allowedOrigins = ['http://myroute.xyz', 'http://clarkconcepts.net','http://localhost'];
        $origin = isset($_SERVER['HTTP_ORIGIN']) ? $_SERVER['HTTP_ORIGIN'] : '';
        if (in_array($origin, $allowedOrigins)) {
            return $next($request)
                ->header('Access-Control-Allow-Origin', $origin)
                ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS')
                ->header('Access-Control-Allow-Headers',' Origin, Content-Type, Accept, Authorization, X-Request-With, cache-control,postman-token, token')
                ->header('Access-Control-Allow-Credentials',' true');
        }
        return $next($request);
    }
}

在app / Http / Kernel.php中在$ middleware部分中添加中间件：

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
    \App\Http\Middleware\TrimStrings::class,
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    \App\Http\Middleware\TrustProxies::class,
    \App\Http\Middleware\Cors::class, //added here
];
