[英]URL Routing in PHP : url routes ony to 404-Not-Found page
[英]PHP routing - How can I implement 404 page on wrong url routes?
每個人。
我有一個在 PHP 中創建的基本路由器。
我可以重定向到我想要的任何頁面,如果有回調 function,回調 function 將被執行,如果有頁面(字符串而不是函數),頁面加載正確的文件。 但是我不知道如何在不存在的路由上實現 404 頁面。
我嘗試重用 preg_match() function,但這沒有給我任何結果,如果我將 notFound() (404 頁)放在 else 塊中,無論 url 是否正確,它總是會被執行。
if(preg_match($pattern, $path, $matches) && $httpMethod === $route['method']) {
}else{
self::notFound(); //THIS GETS EXECUTED ON EVERY ROUTE
}
這是我的代碼。
<?php
class Router{
public static $routes = [];
public static function get($route, $callback){
self::$routes[] = [
'route' => $route,
'callback' => $callback,
'method' => 'GET'
];
}
public static function resolve(){
$path = $_SERVER['REQUEST_URI'];
$httpMethod = $_SERVER['REQUEST_METHOD'];
$methodMatch = false;
$routeMatch = false;
foreach(self::$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['route'])) . "$@D";
$matches = Array();
// check if the current request matches the expression
if(preg_match($pattern, $path, $matches) && $httpMethod === $route['method']) {
// remove the first match
array_shift($matches);
// call the callback with the matched positions as params
if(is_callable($route['callback'])){
call_user_func_array($route['callback'], $matches);
}else{
self::render($route['callback']);
}
}
}
}
public static function render($file, $viewsFolder='./views/'){
include($viewsFolder . $file);
}
public static function notFound(){
http_response_code(400);
include('./views/404.php');
exit();
}
}
Router::get("/", "home.php");
Router::get("/user/:id", function($val1) {
$data = array(
"Nicole",
"Sarah",
"Jinx",
"Sarai"
);
echo $data[$val1] ?? "No data";
});
Router::get("/user/profile/:id", "admin.php");
Router::resolve();
?>
您可以在resolve()
方法的最后添加notFound()
,並在匹配時return
:
public static function resolve(){
$path = $_SERVER['REQUEST_URI'];
$httpMethod = $_SERVER['REQUEST_METHOD'];
$methodMatch = false;
$routeMatch = false;
foreach(self::$routes as $route){
$pattern = "@^" . preg_replace('/\\\:[a-zA-Z0-9\_\-]+/', '([a-zA-Z0-9\-\_]+)', preg_quote($route['route'])) . "$@D";
$matches = Array();
if(preg_match($pattern, $path, $matches) && $httpMethod === $route['method']) {
array_shift($matches);
if(is_callable($route['callback'])){
call_user_func_array($route['callback'], $matches);
}else{
self::render($route['callback']);
}
return;
}
}
notFound();
}
