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; /** * 异常处理 * * Date: 21/03/2018 * @author George * @package App\Exceptions */ class Handler extends ExceptionHandler { use InterfaceResponse; /** * 定义不需要记录的异常类 * * @var array */ protected $dontReport = [ HttpException::class, ValidationException::class, ModelNotFoundException::class, AuthorizationException::class, AuthenticationException::class, ]; /** * A list of the inputs that are never flashed for validation exceptions. * * @var array */ protected $dontFlash = [ 'password', 'password_confirmation', ]; /** * 定义需要记录的异常 * * Date: 21/03/2018 * @author George * @param Exception $exception * @return mixed|void * @throws Exception */ public function report(Exception $exception) { parent::report($exception); } /** * 拦截异常并生成对应的响应内容 * * Date: 21/03/2018 * @author George * @param \Illuminate\Http\Request $request * @param Exception $exception * @return \Illuminate\Contracts\Routing\ResponseFactory|\Symfony\Component\HttpFoundation\Response */ public function render($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); } }
