怎么新建MySQL数据库

    本文给大家分享的时候Laravel下怎样实现返回状态拦截代码的操作，可拦截系统的返回的状态自己在单独处理，小编觉得比较实用，废话不多说，我们直接来看代码，需要的朋友可以参考。

使用查询

composer require betterde/response
// 安装后直接调用以下
# stored
return stored($data, $message = '创建成功');
 
#updated
return updated($data, $message = '更新成功');
 
#deleted
return deleted($message = '删除成功');
 
#accepted
return accepted($message = '请求已接受，等待处理');
 
#notFound
return notFound($message = '您访问的资源不存在');
 
#internalError
return internalError($message = '未知错误导致请求失败');
 
#failed
return failed($message, $code = Response::HTTP_BAD_REQUEST);
 
#success
return success($data);
 
#message
return message($message, $code = Response::HTTP_OK);
 
#respond
return respond($data = [], $message = '请求成功', array $header = []);

拦截代码

App\Exceptions\Handler

<?php
 
namespace App\Exceptions;
 
use Exception;
use Illuminate\Support\Facades\Log;
use Illuminate\Database\QueryException;
use App\Traits\Response\InterfaceResponse;
use Illuminate\Auth\AuthenticationException;
use Illuminate\Validation\ValidationException;
use Illuminate\Auth\Access\AuthorizationException;
use Illuminate\Database\Eloquent\ModelNotFoundException;
use Symfony\Component\HttpKernel\Exception\HttpException;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
use Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException;
 
/**

class Handler extends ExceptionHandler
{
	use InterfaceResponse;
 
 /**

  *
  * @var array
  */
 protected $dontReport = [
		HttpException::class,
		ValidationException::class,
		ModelNotFoundException::class,
		AuthorizationException::class,
		AuthenticationException::class,
	];
 
 /**

  'password',
  'password_confirmation',
 ];
 
	/**

 public function report(Exception $exception)
 {
  parent::report($exception);
 }
 
	/**

	 */
 public function render($request, Exception $exception)
 {
 	// 拦截数据库操作异常
// 	if ($exception instanceof QueryException) {
// 		Log::error($exception);
// 		return $this->internalError();
//		}
 
		// 拦截一般异常并生成响应
		if ($exception instanceof GeneralException) {
			return failed($exception->getMessage(), $exception->getCode() ?: 500);
		}
 
		// 拦截404异常
		if ($exception instanceof ModelNotFoundException) {
			return $this->notFound();
		}
 
		// 拦截授权异常
		if ($exception instanceof AuthorizationException) {
			return failed('您无权访问', 403);
		}
 
		// 参数验证错误的异常，我们需要返回 400 的 http code 和一句错误信息
		if ($exception instanceof ValidationException) {
			return failed(array_first(array_collapse($exception->errors())), 422);
		}
 
		// 用户认证的异常，我们需要返回 401 的 http code 和错误信息
		if ($exception instanceof UnauthorizedHttpException) {
			return failed('未提供Token', 401);
		}
 
		// 捕获404异常
		if ($exception instanceof NotFoundHttpException) {
 		return $this->notFound();
		}
 
  return parent::render($request, $exception);
 }
 
	/**
	 * 认证失败后抛出异常
	 *
	 * Date: 2018/5/27
	 * @author George
	 * @param \Illuminate\Http\Request $request
	 * @param AuthenticationException $exception
	 * @return \Illuminate\Http\JsonResponse|\Illuminate\Http\Response
	 */
	public function unauthenticated($request, AuthenticationException $exception)
	{
		return failed('身份认证失败', 401);
 }
}
