Laravel cors 'Access-Control-Allow-Origin' 和 'Access-Control-Allow-Headers' [英] Laravel cors 'Access-Control-Allow-Origin' and 'Access-Control-Allow-Headers'

问题描述

我是 Laravel 的新手.

我尝试了 https://github.com/barryvdh/laravel-cors.>

当我添加

header('Access-Control-Allow-Origin: *');

在我的 public/index.php 中，它没有在响应中添加 Content-Type.

当我添加

header('Access-Control-Allow-Origin: *');header('Access-Control-Allow-Headers: Origin, Content-Type');

它没有添加 Access-Control-Allow-Origin.

我对在互联网上找到的各种解决方案感到非常困惑.我到底应该怎么做?

解决方案

您可以创建一个新的中间件并将标头添加到响应中:

运行 php artisan make:middleware ModifyHeadersMiddleware

打开文件ModifyHeadersMiddleware，修改handle()方法:

公共函数句柄( $request, Closure $next ){$response = $next( $request );$response->header('Access-Control-Allow-Origin', '*');$response->header('Access-Control-Allow-Headers', 'Origin, Content-Type');返回 $response;}

打开 app/Http/Kernel.php 并在 protected $middleware 数组中添加 ModifyHeadersMiddleware 类.

I am new to Laravel.

I tried https://github.com/barryvdh/laravel-cors.

When I add

header('Access-Control-Allow-Origin: *');

in my public/index.php, it does not add the Content-Type in the response.

When I add

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: Origin, Content-Type');

It does not add Access-Control-Allow-Origin.

I am very confused by all various solutions I find on internet. How exactly should I go about this?

解决方案

You can create a new middleware and add the headers to the response:

Run php artisan make:middleware ModifyHeadersMiddleware

Open the file ModifyHeadersMiddleware and modify the handle() method:

public function handle( $request, Closure $next )
{
    $response = $next( $request );
    $response->header( 'Access-Control-Allow-Origin', '*' );
    $response->header( 'Access-Control-Allow-Headers', 'Origin, Content-Type' );

    return $response;
}

Open app/Http/Kernel.php and in the protected $middleware array add the ModifyHeadersMiddleware class.
