laravel - 请求的资源 laravel 5.8.8 上没有“Access-Control-Allow-Origin”标头

Question

我已经按照 github 存储库中的自述文件中的说明安装了 barryvdh/laravel-cors。我仍然在请求的资源错误中出现 No 'Access-Control-Allow-Origin' 标头。我正在使用 vue、axios 和 laravel 5.8.8

安装 barryvdh/laravel-cors 并在我的 api.php 文件中添加标题

我的 cors.php 文件看起来像这样

'supportsCredentials' => false,
    'allowedOrigins' => ['*'],
    'allowedOriginsPatterns' => [],
    'allowedHeaders' => ['Content-Type', 'X-Requested-With', 
                    'Origin','Authorization'],
    'allowedMethods' => ['*'],
    'exposedHeaders' => [],
    'maxAge' => 0,

在调试器工具中，我得到以下信息

Answer 1

我找到了解决方案。我在我的 axios URL 中添加了 index.php，例如http://127.0.0.1:8000/index.php/api/ ...

Answer 2

你会用

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

header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS'); header('Access-Control-Allow-Headers: Content-Type, Authorization, X-Requested-With');

而不是barryvdh/laravel-cors

在

public/index.php 

以上

require __DIR__.'/../bootstrap/autoload.php';

样本：

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
header('Access-Control-Allow-Headers: Content-Type, Authorization, X-Requested-With');
require __DIR__.'/../bootstrap/autoload.php';
