Slim 3在中间件中获取当前路由

Question

我想在中间件类中获取当前I路由的名称.以前(在Slim 2.*中)你可以像这样获取当前路线:

$route = $this->app->router->getCurrentRoute();

但是这个功能已经在3.0版的Slim中被删除了.我在以下__invoke方法中找到了以下代码Slim\App:

    // Get the route info
    $routeInfo = $request->getAttribute('routeInfo');

    /** @var \Slim\Interfaces\RouterInterface $router */
    $router = $this->container->get('router');

    // If router hasn't been dispatched or the URI changed then dispatch
    if (null === $routeInfo || ($routeInfo['request'] !== [$request->getMethod(), (string) $request->getUri()])) {
        $request = $this->dispatchRouterAndPrepareRoute($request, $router);
        $routeInfo = $request->getAttribute('routeInfo');
    }

这表明,当前的路线被存储为属性routeInfo的Request.但似乎我的自定义中间件类在设置属性之前被调用(通过该$this->dispatchRouterAndPrepareRoute($request, $router);方法).因为呼叫$request->getAttribute('routeInfo')解决了NULL.

所以我的问题是; 如何从中间件函数/类中获取当前路由(或路由名称)？

或者我应该只复制上面的代码Slim\App？

对于Slim3,这里有一个示例,向您展示如何从中间件中获取路由信息,这实际上是先前答案放在一起的组合.

<?php

$slimSettings = array('determineRouteBeforeAppMiddleware' => true);

// This is not necessary for this answer, but very useful
if (ENVIRONMENT == "dev")
{
    $slimSettings['displayErrorDetails'] = true;
}

$slimConfig = array('settings' => $slimSettings);
$app = new \Slim\App($slimConfig);


$myMiddleware = function ($request, $response, $next) {

    $route = $request->getAttribute('route');
    $routeName = $route->getName();
    $groups = $route->getGroups();
    $methods = $route->getMethods();
    $arguments = $route->getArguments();

    print "Route Info: " . print_r($route, true);
    print "Route Name: " . print_r($routeName, true);
    print "Route Groups: " . print_r($groups, true);
    print "Route Methods: " . print_r($methods, true);
    print "Route Arguments: " . print_r($arguments, true);
};

// Define app routes
$app->add($myMiddleware);


$app->get('/', function (\Slim\Http\Request $request, Slim\Http\Response $response, $args) {
    # put some code here....
})

就我而言,我想添加中间件以确保用户在某些路由上登录,如果不是,则将其重定向到登录页面.我发现最简单的方法就是->setName()在路由上使用:

$app->get('/', function (\Slim\Http\Request $request, Slim\Http\Response $response, $args) {
    return $response->withRedirect('/home');
})->setName('index');

然后,如果此路由匹配,$routeName则中间件示例中将是"index".然后,我定义了不需要身份验证的路由的数组列表,并检查当前路由是否在该列表中.例如

if (!in_array($routeName, $publicRoutesArray))
{
    # @TODO - check user logged in and redirect if not.
}

Answer 2

显然,您可以使用此设置配置Slim以确定进入中间件之前的路由:

$app = new Slim\App([
    'settings'  => [
        'determineRouteBeforeAppMiddleware' => true,
    ]
]);

我不确定它有什么样的影响,但它对我有用:)

Answer 3

$request->getUri()->getPath()

获取当前路线,即使在middleware.
