Php路由解析器URL的末尾 - Php route parser end of the URL

Php route parser end of the URL

本文关键字：URL 路由 Php | 更新日期: 2024-02-14

我为自己的phpmvc框架编写了一个小的phpurl解析器，在以下代码中我几乎不需要帮助：

<?php
class Route{
private $routes = [];
public function __construct(){}
public function addRoute($method, $url, $callback){
    $this->routes[] = array('method' => $method, 
                          'url' => $url, 
                          'callback' => $callback);
}
public function doRouting(){
    $reqUrl = $_SERVER['REQUEST_URI'];
    $reqMet = $_SERVER['REQUEST_METHOD'];
    foreach($this->routes as  $route) {
        // convert urls like '/users/:uid/posts/:pid' to regular expression      
        $pattern = "@^" . preg_replace('/''':[a-zA-Z0-9'_'-]+/', '([a-zA-Z0-9'-'_]+)', preg_quote($route['url'])) . "$@D";
        $matches = array();
        if($reqMet == $route['method'] && preg_match($pattern, $reqUrl, $matches)) {
            // remove the first match
            array_shift($matches);
            // call the callback with the matched positions as params
            return call_user_func_array($route['callback'], $matches);
        }
    }
}
$route = new Route();
$route->addRoute('GET', '/', function(){
     echo 'root';
});
 $route->addRoute('GET', '/users/', function(){
     echo 'users';
 });
 $route->addRoute('GET', '/users/:uid/posts/:pid/', function($uid, $pid){
     echo $uid.'<br/>'.$pid;
 });
 $route->addRoute('GET', '/users/:uid/posts/:pid/edit', function($uid, $pid){
     echo 'users posts edit';
 });

 $route->doRouting();

我希望在URL的末尾允许一个可选的/。例如，在这个当前路由定义中，当REQUEST_URI是/users/123/posts/456时，我希望在REQUEST_URI是/users/123/posts/456/时得到相同的结果（函数调用）。

此外，/users/123/posts/456/edit调用新函数。

如果需要，从您的路线上删除尾随斜线：

$route['url'] = rtrim($route['url'], '/');

然后相应地终止您的路线模式：

$pattern = preg_replace('/''':[a-zA-Z0-9'_'-]+/', '([a-zA-Z0-9'-'_]+)', preg_quote($route['url'], '@'));
$pattern = "@^$pattern/?$@D";

在执行路由之前，您可以只rtrim和$_SERVER['REQUEST_URI']：

$reqUrl = $_SERVER['REQUEST_URI'];
$reqUrl = rtrim($reqUrl, '/');

但这样做时，不要在路由定义中添加斜杠：

$route->addRoute('GET', '', ...
$route->addRoute('GET', '/users/:uid/posts/:pid', ...

将此代码放在当前代码中，以便验证URL

$url="some/url/";
$slash=substr($url, -1); // returns "/"
//remove the '/' from end of the url
if($slash=="/") {
trim($slash, "/"); //many alternatives can be used for this function
}

在上面的代码中，它会检查你的url，如果它在url中，就会删除"/"，所以基本上它会做与url相同的事情，最后没有斜杠
希望对有所帮助
