如何在 Laravel 中基于 application/json 标头加载路由

我正在使用application/json标头来控制我的控制器在收到请求时的行为。我需要在单元测试中的 POST 中包含application/json header.

我试过了：

public function testStore()
    {
        $this->validator
            ->shouldReceive('validate')
            ->once()
            ->with($this->attributes)
            ->andReturn(true);

        $this->repository
            ->shouldReceive('create')
            ->once()
            ->with($this->attributes)
            ->andReturn($this->entity);

        $this->controller
            ->shouldReceive('creationSucceeded')
            ->once()
            ->with($this->entity);

        $this->client->request('POST', 'shared/users', [], [], [
                'HTTP_CONTENT_TYPE' => 'application/json'
            ], json_encode($this->attributes));

        $this->assertResponseStatus(201);
    }

而它的Request::isJson()在我的控制器中继续返回 false。

我也尝试过使用'CONTENT_TYPE' => 'application/json'而不是HTTP_CONTENT_TYPE above.

就我而言，我正在使用Content-Type确定要加载的控制器。这对我不起作用，因为路由会在以下情况下加载到内存中：TestCase->createApplication()正在运行。这意味着我的标题没有效果。

我最终做了一个RouteInflector这允许我强制我的测试使用 Api 路由。

class ApiTestCase extends TestCase
{

    /**
     * @inheritDoc
     */
    public static function setUpBeforeClass()
    {
        /**
         * Routes are loaded into memory before tests are run.
         * Because of this, we can't have routing logic based on
         * heads.  Using the RouteInflector we can override
         * header to createApplication() and must use a constant
         * to force the RouteInflector to use Api controllers.
         */
        RouteInflector::isJson(true);
    }

    public function setUp()
    {
        parent::setUp();

        //Lets do this right
        $this->client->setServerParameter('HTTP_CONTENT_TYPE', 'application/json');
        $this->client->setServerParameter('HTTP_ACCEPT', 'application/json');
    }

}

偏转器：

class RouteInflector
{

    /** @var bool */
    protected static $isJson = false;

    /**
     * Review the request details and determine which controller
     * subpackage should be used.

     * We could also check the request source to help determine the
     * package.
     *
     * Defaults to Web.
     *
     * @return string
     */
    public function getControllerSubpackage()
    {
        if (self::isJson() || Request::isJson()) {
            return 'Api';
        }

        return 'Web';
    }

    /**
     * Used by tests to tell routing that the current request
     * is a json request.
     *
     * @see \Tests\ApiTestCase
     *
     * @param bool|null $isJson
     *
     * @return bool Only provided if parameter is null
     */
    public static function isJson($isJson = null)
    {
        if (is_null($isJson)) {
            return self::$isJson;
        } else {
            self::$isJson = $isJson;
        }
    }
}
