介绍

laravel-response 主要用来统一 API 开发过程中「成功」、「失败」以及「异常」情况下的响应数据格式。

实现过程简单,在原有的 response()->json()进行封装,使用时不需要有额外的心理负担。

遵循一定的规范,返回易于理解的 HTTP 状态码,并支持定义 ResponseCodeEnum 来满足不同场景下返回描述性的业务操作码。

概览

  • 统一的数据响应格式,固定包含:codestatusdatamessageerror
  • 内置 Http 标准状态码支持,同时支持扩展 ResponseCodeEnum 来根据不同业务模块定义响应码
  • 响应码 code 对应描述信息 message 支持本地化,支持配置多语言
  • 合理地返回 Http 状态码
  • 根据 debug 开关,合理返回异常信息、验证异常信息等
  • 支持格式化 Laravel 的 Api ResourceApi Resource CollectionPaginator(简单分页)、LengthAwarePaginator(普通分页)、Eloquent\ModelEloquent\Collection,以及简单的 arraystring等格式数据返回
  • 分页数据格式化后的结果与使用 league/fractal (DingoApi 使用该扩展进行数据转换)的 transformer 转换后的格式保持一致,也就是说,可以顺滑地从 Laravel Api Resource 切换到 league/fractal

安装

支持 Laravel 8/Lumen 8 以上版本,自定义业务操作码部分依赖于 jiannei/laravel-enum,需要先进行安装。

$ composer require jiannei/laravel-enum -vvv
$ composer require jiannei/laravel-response -vvv

配置

Laravel

  • 发布配置文件
$ php artisan vendor:publish --provider="LSvKing\Response\Laravel\Providers\LaravelServiceProvider"
  • 格式化异常响应

app/Exceptions/Handler.php 中 引入 use LSvKing\Response\Laravel\Support\Traits\ExceptionTrait; 引入以后,对于 ajax 请求产生的异常都会进行格式化数据返回。

Lumen

  • 复制配置文件到 vendor/jiannei/laravel-response/config/response.php,到 config/response.php
cp vendor/jiannei/laravel-response/config/response.php config/response.php
  • 加载配置
// bootstrap/app.php
$app->configure('response');
  • 格式化异常响应

app/Exceptions/Handler.php 中 引入 use LSvKing\Response\Laravel\Support\Traits\ExceptionTrait;

app/Http/Controllers/Controller.php 中引入 use LSvKing\Response\Laravel\Support\Traits\ExceptionTrait;

  • 注册服务容器
$app->register(\LSvKing\Response\Laravel\Providers\LumenServiceProvider::class);

使用

扩展包本身提供了丰富的单元测试用例tests ,也可以直接查看测试用例。

或者查看相应的模板项目:

Laravel 版本 Api 开发初始化项目:laravel-api-starter

Lumen 版本 Api 开发初始化项目:lumen-api-starter

成功响应

  • 示例代码
<?php
public function index()
{
    $users = User::all();

    return Response::success(new UserCollection($users));
}

public function paginate()
{
    $users = User::paginate(5);

    return Response::success(new UserCollection($users));
}

public function simplePaginate()
{
    $users = User::simplePaginate(5);

    return Response::success(new UserCollection($users));
}

public function item()
{
    $user = User::first();

    return Response::success(new UserResource($user));
}

public function array()
{
    return Response::success([
        'name' => 'Jiannel',
        'email' => 'longjian.huang@foxmail.com'
    ],'', ResponseCodeEnum::SERVICE_REGISTER_SUCCESS);
}
