每当调用函数时自动创建日志（将数据插入 table）

Question

我是 laravel 和 php 的新手。我的 主要目标 是在每次调用函数时调用 createLogs()，而不是将调用方法放在每个函数中，因为这很麻烦。我需要帮助。

我制作了一个名为 WebLogs 的控制器，其中包含一个名为 createLogs() 的函数，可将数据插入 table。我希望在调用另一个函数时自动调用它。我尝试使用 this solution 并将其放在 Controller class 中，因为 WebLogs 扩展了 Controller class，而我所有其他控制器都扩展了 Controller class，但解决方案似乎不起作用。

所以我的 Controller class 现在看起来像这样：

class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    // Added this function from the solution I mentioned
    public function __call($method, $arguments) {
        echo 'hello world';
        echo '<br><br>';
        echo $method;

        if(method_exists($this, $method)) {
            return call_user_func_array(array($this,$method),$arguments);
        }
     }
 }

示例控制器：

class DashboardController extends Controller
{
    public function index()
    {
        (new WebLogs)->createLogs(); //I don't want to call this for every function
        return view('dashboard');
    }
    public function showSomething()
    {
        (new WebLogs)->createLogs();
        return view('something');
    }
    public function updateSomething()
    {
        (new WebLogs)->createLogs();
        return redirect()->back()->with('message','yeey');
    }
}

DashboardController 中的函数如何从 web.php 中调用：

Route::get('/', [DashboardController::class, 'index'])->name('dashboard');
Route::get('/something', [DashboardController::class, 'showSomething'])->name('something');
Route::post('/something/update', [DashboardController::class, 'updateSomething'])->name('something.update');

创建 app\Classes\WebLogs.php 内容：

<?php
namespace App\Classes;

class WebLogs {
    public function __construct() {
      return "WebLogs class with construct function was initialized.";
    }
    public function createLogs($routeName,$routePath) {
      $status = 0;
      logger('WebLogs class is running:');
      logger([$routeName,$routePath]);
      // Save to database here
      // ...
      return $status;
    }
}

然后，创建一个AutoCreateLogs中间件，它会保存为app\Http\Middleware\AutoCreateLogs.php:

$ php artisan make:middleware AutoCreateLogs

含内容：

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use App\Classes\WebLogs;

class AutoCreateLogs
{
    public function handle(Request $request, Closure $next)
    {
        $route = Route::current();
        $routePath = $route->uri;
        $routeName = $route->action['as'];
        $w = new WebLogs;
        $w->createLogs($routeName,$routePath);
        return $next($request);
    }
}

并像这样使用这个中间件：

Route::middleware([AutoCreateLogs::class])->group(function () {
  Route::get('/', [App\Http\Controllers\DashboardController::class, 'index'])->name('dashboard');
  Route::get('/something', [App\Http\Controllers\DashboardController::class, 'showSomething'])->name('something');
  Route::post('/something/update', [App\Http\Controllers\DashboardController::class, 'updateSomething'])->name('something.update');
  Route::get('/something/{value}', [App\Http\Controllers\DashboardController::class, 'getSomething'])->name('get.something');
});

与app\Http\Controllers\DashboardController.php:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class DashboardController extends Controller
{
    public function index()
    {
        $page = 'index';
        return view('welcome', ['page'=>$page]);
    }

    public function showSomething()
    {
        $page = 'showSomething';
        return view('welcome', ['page'=>$page]);
    }

    public function updateSomething()
    {
        $page = 'updateSomething';
        return response()->json(['page'=>$page]);
    }

    public function getSomething(Request $request)
    {
        $page = 'getSomething';
        return view('welcome', ['page'=>$page]);
    }
}

然后，清空 storage\logs\laravel.log，并使用示例路线运行 http://laravel-me.com/something/value99 它将显示成功的结果：

[2022-02-18 22:56:09] local.DEBUG: WebLogs class is running:  
[2022-02-18 22:56:09] local.DEBUG: array (
  0 => 'get.something',
  1 => 'something/{value}',
)
