Accessing parameters in Slim v3 middleware

本文关键字：参数中间件 Slim v3 访问 | 更新日期: 2023-09-27

根据http://www.slimframework.com/docs/concepts/middleware.html，添加路由中间件如下:

<?php
$app = new 'Slim'App();
$mw = function ($request, $response, $next) {
    // How is $arg accessed?
    $response->getBody()->write('BEFORE');
    $response = $next($request, $response);
    $response->getBody()->write('AFTER');
    return $response;
};
$app->get('/ticket/{id}', function ($request, $response, $args) {
    $response->getBody()->write(' Hello ');
    // $arg will be ['id'=>123]
    return $response;
})->add($mw);
$app->run();

$arg为参数数组。如何在中间件中访问它?

http://help.slimframework.com/discussions/questions/31-how-pass-route-pram-to-middleware显示了一种方法，但是，似乎是Slim的早期版本，错误是Fatal error: Call to undefined method Slim''Route::getParams()。

路由参数可以通过请求时的routeInfo属性访问，如

$app->get('/hello/{name}', 'HelloWorld::class . ':execute')
    ->add(function ($request, $response, $next) {
        var_dump($request->getAttribute('routeInfo')[2]['name']);exit();
        return $next($request, $response);
    });
