laravel在中间件内生成参数并且传递到控制器中的2种姿势_php实例_

 class MidParams //中间件 { public function handle($request, Closure $next) { $mid_params = ['mid_params'=>'this is mid_params']; $request->attributes->add($mid_params);//添加参数 return $next($request);//进行下一步(即传递给控制器) } } 

 class MidController extends Controller { //控制器 public function testMidFunc(Request $request) { $input_params = $request->input();//获取参数 $mid_params = $request->get('mid_params');//中间件产生的参数 return ['my_params'=>$input_params, 'mid_params'=>$mid_params]; //注意：$request->attributes->add这种方法 input()取不到值 只能用get('xxx')取到值 } }

 class MidParams //中间件 { public function handle($request, Closure $next) { $mid_params = ['mid_params'=>'this is mid_params']; $request->merge($mid_params);//合并参数 return $next($request); } }

 class MidController extends Controller { //控制器 public function testMidFunc(Request $request) { $all_params = $request->input();//获取参数 return ['all_params'=>$all_params]; } }
