找不到路线。 PHP

Question

我正在尝试在我自己的 mvc 框架中进行路由。像 /controller/action 这样的简单路由在以下情况下正常工作： index.php

$router = new Core\Router();

//添加路由

$router->add('{controller}/{action}');

路由器：

public function add($route, $params = [])
    {
        // Convert the route to a regular expression: escape forward slashes
        $route = preg_replace('/\//', '\\/', $route);

        // Convert variables e.g. {controller}
        $route = preg_replace('/\{([a-z]+)\}/', '(?P<\1>[a-z-]+)', $route);

        // Convert variables with custom regular expressions e.g. {id:\d+}
        $route = preg_replace('/\{([a-z]+):([^\}]+)\}/', '(?P<\1>\2)', $route);

        // Add start and end delimiters, and case insensitive flag
        $route = '/^' . $route . '$/i';

        $this->routes[$route] = $params;
    }

    /**
     * Get all the routes from the routing table
     *
     * @return array
     */
    public function getRoutes()
    {
        return $this->routes;
    }

    /**
     * Match the route to the routes in the routing table, setting the $params
     * property if a route is found.
     *
     * @param string $url The route URL
     *
     * @return boolean  true if a match found, false otherwise
     */
    public function match($url)
    {
        foreach ($this->routes as $route => $params) {
            if (preg_match($route, $url, $matches)) {
                // Get named capture group values
                foreach ($matches as $key => $match) {
                    if (is_string($key)) {
                        $params[$key] = $match;
                    }
                }

                $this->params = $params;
                return true;
            }
        }

        return false;
    }

    /**
     * Get the currently matched parameters
     *
     * @return array
     */
    public function getParams()
    {
        return $this->params;
    }

    /**
     * Dispatch the route, creating the controller object and running the
     * action method
     *
     * @param string $url The route URL
     *
     * @return void
     */
    public function dispatch($url)
    {
        $url = $this->removeQueryStringVariables($url);

        if ($this->match($url)) {
            $controller = $this->params['controller'];
            $controller = $this->convertToStudlyCaps($controller);
            $controller = $this->getNamespace() . $controller;

            if (class_exists($controller)) {
                $controller_object = new $controller($this->params);

                $action = $this->params['action'];
                $action = $this->convertToCamelCase($action);

                if (is_callable([$controller_object, $action])) {
                    $controller_object->$action();

                } else {
                    throw new \Exception("Method $action (in controller $controller) not found");
                }
            } else {
                throw new \Exception("Controller class $controller not found");
            }
        } else {
            throw new \Exception('No route matched.', 404);
        }
    }

但是当我尝试在我的 index.php 中添加另一条路线时：/controller/id/action 与：

$router->add('{controller}/{id:\d}/{action}');

显示找不到路由异常。我在这里做错了什么。谁能告诉我如何解决这个问题？

我遇到了同样的问题。我认为 add 方法中的 if 和 list 是必需的，而在 match 方法中 $param 参数需要 $this->$params = $param 这是我编写该代码时的错误。

class Router {

    protected $routes = [];
    protected $params  = [];

    public function add($route,$action) {

        $route = preg_replace('/^\//','',$route);
        $route = preg_replace('/\//','\\/',$route);
        $route = preg_replace('/\{([a-z]+)\}/','(?<\1>[a-z0-9-]+)',$route);
        $route = '/^'. $route .'\/?$/i';

        $action = is_array($action) ? $action ['uses'] : $action;

        list($params['controller'] , $params['method']) = explode('@',$action);

        $this->routes[$route] = $params;
    }

      
    public function match($url) {
        foreach ($this->routes as $route => $param) {

            if(preg_match($route , $url , $matchess)) {

                    foreach ($matchess as $key => $match){
                        if(!is_numeric($key)) {
                            $param [$key] = $match;
                        }
                    }
                $this->params = $param;
                return true;
            }
        }
        return false;
    }

    public function getRoutes(): array {
        return $this->routes;
    }

    public function getParams() {
        return $this->params;
    }
}
