In the TP5.0 API interface, when the front-end personnel make a wrong request, we should judge whether the requested module, controller, and method exist, and if they do not exist, the friendly output
New Base.phpAll classes inherit Base.phpclass, there is no output for the friendly method
namespace app\index\controller;
use think\Controller;
class Base extends Controller
{
public function _empty($name)
{
return show('404','请求的方法不存在',[],'404');
}
}
New Error.phpclass for output-friendly non-existent controller
can be modified config.phpunder the 'empty_controller' => 'Error',changes specified error class name
namespace app\index\controller;
class Error
{
public function _empty($name){
return show('404','请求的控制器不存在',[],'404');
}
