关于php:laravel-中根据请求路径方法匹配路由实例

需要

最近因为业务性能的需要，须要依据数据库记录的申请门路 (如admin/auth/menu/46/edit)、申请办法(如GET) 去匹配路由实例，拿到路由实例后续做一些其余事件。

剖析

其实就是路由的外围性能(将一类申请映射匹配到一个回调类型的变量)。框架自身自带的性能，查找源码是以下代码块实现的：

// Illuminate/Routing/RouteCollection.php
public function match(Request $request)
{
    // 1. 获取路由汇合
    $routes = $this->get($request->getMethod());
    
    // 2. 匹配路由
    $route = $this->matchAgainstRoutes($routes, $request);

    return $this->handleMatchedRoute($request, $route);
}

// Illuminate/Routing/AbstractRouteCollection.php
protected function matchAgainstRoutes(array $routes, $request, $includingMethod = true)
{[$fallbacks, $routes] = collect($routes)->partition(function ($route) {return $route->isFallback;});

    return $routes->merge($fallbacks)->first(function (Route $route) use ($request, $includingMethod) {
        // 3. 遍历匹配
        return $route->matches($request, $includingMethod);
    });
}

// Illuminate/Routing/Route.php
public function matches(Request $request, $includingMethod = true)
{$this->compileRoute();

    foreach ($this->getValidators() as $validator) {
        // 4. 遍历验证器验证匹配
        if (! $includingMethod && $validator instanceof MethodValidator) {continue;}

        if (! $validator->matches($this, $request)) {return false;}
    }

    return true;
}

代码大略逻辑是：遍历路由汇合，将以后申请丢给四个验证器 UriValidator、MethodValidator、SchemeValidator、HostValidator 去逐个验证匹配，验证器次要去验证匹配申请对象的 pathInfo、method、scheme、host 信息。

所以只须要批改以后的申请对象的这些信息，丢给下面的 matches 办法就能够实现我须要的性能了。

实现

因为是同一个我的项目，所以 scheme、host 与以后申请统一无需批改。而 pathInfo、method 是两个公有属性以及没有找到对应写权限的办法。所以实现一个有能力写属私性的宏办法即可。最终代码如下：

<?php

namespace App\Support\Macros;

use Illuminate\Routing\Route;
use Illuminate\Routing\Router;
use Illuminate\Support\Arr;
use InvalidArgumentException;

class RequestMacro
{
    /**
     * 批改属性
     */
    public function propertyAware(): callable
    {return function ($property, $value){
            /** @var \Illuminate\Http\Request $this */
            if (! property_exists($this, $property)) {throw new InvalidArgumentException('The property not exists.');
            }
            $this->{$property} = $value;

            return $this;
        };
    }
    
     /**
     * 匹配路由
     */
    public function matchRoute(): callable
    {return function ($includingMethod = true){
             // 1. 获取路由汇合
            /* @var \Illuminate\Routing\RouteCollection $routeCollection */
            $routeCollection = app(Router::class)->getRoutes();
            /** @var \Illuminate\Http\Request $this */
            $routes = is_null($this->method())
                ? $routeCollection->getRoutes()
                : Arr::get($routeCollection->getRoutesByMethod(), $this->method(), []);
            [$fallbacks, $routes] = collect($routes)->partition(function ($route){return $route->isFallback;});

            return $routes->merge($fallbacks)->first(function (Route $route) use ($includingMethod){
                // 2. 遍历匹配
                return $route->matches($this, $includingMethod);
            });
        };
    }
}

注册申请宏

// App\Providers\AppServiceProvider
public function register()
{Request::mixin($this->app->make(RequestMacro::class));
}

应用示例

$route = request()
    ->propertyAware('pathInfo', \Illuminate\Support\Str::start('admin/auth/menu/46/edit', '/'))
    ->propertyAware('method', 'GET')
    ->matchRoute();

dump($route);
