Laravel框架实现利用中间件进行操作日志记录功能

php artisan make:middleware AdminOperationLog

<?phpnamespace App/Http/Middleware;use Closure;use Illuminate/Http/Request;use Illuminate/Support/Facades/Auth;use App/Http/Models/OperationLog;class AdminOperationLog{  /**   * Handle an incoming request.   *   * @param /Illuminate/Http/Request $request   * @param /Closure $next   * @return mixed   */  public function handle($request, Closure $next)  {    $user_id = 0;    if(Auth::check()) {      $user_id = (int) Auth::id();    }    $_SERVER['admin_uid'] = $user_id;    if('GET' != $request->method()){      $input = $request->all();      $log = new OperationLog(); # 提前创建表、model      $log->uid = $user_id;      $log->path = $request->path();      $log->method = $request->method();      $log->ip = $request->ip();      $log->sql = '';      $log->input = json_encode($input, JSON_UNESCAPED_UNICODE);      $log->save();  # 记录日志    }    return $next($request);  }}

protected $middlewareGroups = [    'web' => [      ...      /App/Http/Middleware/AdminOperationLog::class,      ...    ],    'api' => [      'throttle:60,1',      'bindings',    ],  ];
