找不到路线。 PHP

【中文标题】找不到路线。 PHP【英文标题】:Route not found. PHP 【发布时间】:2018-02-24 21:12:43 【问题描述】: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:
$router->add('controller/id:\d/action');
显示找不到路由异常。我在这里做错了什么。谁能告诉我如何解决这个问题?
【问题讨论】:
如果你想一路走下去,请记住大多数路由系统需要容纳相当任意数量的路由,甚至数千个,并且仍然表现良好。这通常意味着将所有路由编译成一个紧凑的状态机,或者一个非常复杂的单数正则表达式。 所以生成的正则表达式是:^(?P<controller>[a-z-]+)\/(?P<id>\d)\/(?P<action>[a-z-]+)$
。我认为应该是\d+
。无论如何,快速的解决方案 - 以已经工作的路由器为例,我喜欢这个 one
您尝试路由到的示例 url 是什么?它会抛出“没有匹配的路线”。例外?另外,你能显示你的 removeQueryStringVariables 函数吗,也许它弄乱了 url?
【参考方案1】:
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;

我正在学习 MVC,我有同样的问题,我认为 add 方法中的 if 和 list 是必需的,并且在 match 方法中 $param 参数需要 $this->$params = $param 那是我的我写那段代码时的错误。 谢谢,我只是将它添加到您的答案中!以上是关于找不到路线。 PHP的主要内容,如果未能解决你的问题,请参考以下文章
车队推车在路线中使用中间件,但我在项目中找不到任何 $routemiddleware...甚至在 kernel.php 中也找不到...我在哪里可以找到它?
