Question

我在应用程序中为Slim请求创建了一个包装器，以便能够在Request对象上创建一些自定义方法。

class Request extends SlimRequest
{
   /**
    * Get authorization token.
    *
    * @return null|string
    */
   public function getAuthToken(): ?string
   {
       return $this->getHeaderLine('FOOBAR-TOKEN');
   }

   /**
    * Retrieves a route parameter.
    *
    * @param string $name
    * @return string|null
    */
   public function getRouteParam(string $name): ?string
   {
       return $this->getRoute()->getArgument($name);
   }

   /**
    * Retrieves the route instance.
    *
    * @return Route
    */
   public function getRoute(): Route
   {
       return $this->getAttribute('route');
   }

}

尝试为此类创建单元测试时出现我的问题。我一直在测试请求的方式是通过在环境模拟中使用Slims构建。我在第一个函数中向请求添加了标头，如下所示，但我不知道如何向请求添加Route对象

$request = Request::createFromEnvironment(Environment::mock());
$request = $request->withHeader('FOOBAR-TOKEN', 'superSafeExampleToken');

我尝试使用请求选项创建请求，但是$ this-> getAttribute（'route'）;返回null

   $requestOptions = [
        'REQUEST_METHOD' => 'POST,
        'REQUEST_URI' => '/foo/bar',
        'QUERY_STRING' => http_build_query($requestParameters),
    ];
    $environment = Environment::mock($requestOptions);

好的，解决方案如下

public function testGetRouteParam()
{
    $route = $route = new Route('GET', '/foo/{bar}', []);
    $route->setArguments(['bar' => 1]);
    $request = Request::createFromEnvironment(Environment::mock());
    $request = $request->withAttribute('route', $route);

    $this->assertEquals(1, $request->getRouteParam('bar'));
    $this->assertNull($request->getRouteParam('baz'));
}
