如何为路由组中的所有请求设置标头 [英] How to set header for all requests in route group

问题描述

我正在使用Laravel 5.4创建一个API，并且一切正常.我已经使用了以下中间件=> auth:api

I'm creating an API with Laravel 5.4 and it all works well. I've used the following middleware => auth:api like this

Route::group(['middleware' => 'auth:api'], function(){ 
    Route::get('URIValue', ControllerName@action) //Example
});

我已经用邮递员对其进行了测试，当请求标头包含以下键和值时，它可以很好地工作:

I've tested it with postman and it works well when the request header contains the following keys and values :

• 授权:承载api_token
• Accept:application/json

当api_token无效时，将执行Handler类的未经身份验证的功能. laravel返回的默认响应是

When the api_token is invalid the unauthenticated function of the Handler class is executed. The default response that laravel returns is

'error' => 'Unauthenticated' // in JSON format

但是，当未设置Accept标头时，laravel默认返回一个视图.但是使用API​​时，视图是不可接受的.

But when the Accept header is not set, laravel returns a view by default. But with an API, views are not acceptable.

对于路由组中的每个路由请求，我如何强制laravel检查是否为正确的值设置了Accept报头(在这种情况下，该值必须为=> accept/json)?

How can I force laravel to check that the Accept header is set with the right value (in this case the value must be => accept/json) for every single request for the routes that are in the route group?

类似的东西:

protected function mapApiRoutes()
{
    Route::prefix('api')
          ->middleware('api')
          ->namespace($this->namespace)
          ->header('Accept' => 'application/json') //this
          ->group(base_path('routes/api.php'));
}

或

Route::group(['middleware'  => 'auth:api', 
              'headers'     => ['Accept' => 'application/json']
             ], function(){ 
                    Route::get('URIValue', ControllerName@action) //Example
             });

推荐答案

您可以为此创建一个中间件.

You can create a middleware for that.

您将检查并强制执行A​​ccept标头，以便Laravel无论如何都将输出json.

You'll have check and enforce the Accept header so Laravel will output json no matter what..

class WeWantJson
{
    /**
     * We only accept json
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $acceptHeader = $request->header('Accept');
        if ($acceptHeader != 'application/json') {
            return response()->json([], 400);
        }

        return $next($request);
    }
}

然后在您的App\Http\Kernel中，您可以将中间件添加到您的api组中.然后，无需手动将其添加到路由/路由组中.

And in your App\Http\Kernel you can add the middleware to you api group. Then there's no need to manually add it in the routes/routegroups.

您还可以添加一个中间件来强制执行json，无论如何...

You could also add a middleware to enforce json no matter what...

class EnforceJson
{
    /**
     * Enforce json
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $request->headers->set('Accept', 'application/json');

        return $next($request);
    }
}
