Laravel 5.5+ Dingo +Jwt 快速搭建 API系统

	刚进入新公司，比较忙，只能抽时间来写写比较简短的博文总结，还望见谅。
	最近公司要从实业转型线上，决定用laravel 来做快速开发，而一些同事之前没有用过laravel，尤其是api 的快速搭建，一致想让我把搭建过程给分享出来，此为背景

搭建过程记录 laravel 5.5 __ 创建 laravel 项目

composer create-project --prefer-dist laravle/laravel myProject  '5.5.*'

__ 安装 Dingo

"require":{
		"dingo/api": "1.0.0-beta8"
},
"minimum-stability":"dev",

执行安装

composer update

安装jwt

composer require tymon/jwt-auth:dev-develop --prefer-source

配置项目 config/app.php

"providers"=>[
		...
		Dingo\Api\Provider\LaravelServiceProvider::class,
		Tymon\JWTAuth\Providers\LaravelServiceProvider::class,
],

'aliases' => [
    ...
    'JWTAuth' => Tymon\JWTAuth\Facades\JWTAuth::class，
		'JWTFactory' => Tymon\JWTAuth\Facades\JWTFactory::class
]

发布配置文件 : 终端执行

php artisan vendor:publish --provider="Dingo\Api\Provider\LaravelServiceProvider"  //生成 api.php
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"  //生成 jwt.php

或者
php artisan vendoer:publish 
选择编号即可发布

生成 JWT_SECRET 写入.env

php artisan jwt:secret  

config/api.php

'auth' => [
    'jwt' => Dingo\Api\Auth\Provider\JWT::class
]

在 .env 中，把 dingo 配置在最后

API_STANDARDS_TREE=vnd // 环境
API_SUBTYPE=myapp // 子类型
API_PREFIX=api // 前缀
API_DOMAIN=api.myapp.com //子域名  （前缀和子域名只能存在一个）可选
API_VERSION=v1 // 版本
API_NAME=My API // 名字（使用API Blueprint命令才会用到）
API_CONDITIONAL_REQUEST=false // 带条件的请求
API_STRICT=false // Strict模式
API_DEFAULT_FORMAT=json // 响应格式
API_DEBUG=true // 调试模式

上面的配置不是都是必要的，可根据实际情况进行选择（上面配置时参考网络配置）,如：

API_STANDARDS_TREE=vnd
API_SUBTYPE=emall
API_PREFIX=api
API_VERSION=v1

__

路由： 在routers/api.php中新建内容，两个路径分别是注册和登录：

//接管路由
$api = app('Dingo\Api\Routing\Router');

$api->version('v1', function ($api) {
		 $api->post('login', 'App\Http\Controllers\Api\Auth\LoginController@login');
		 $api->post('register', 'App\Http\Controllers\Api\Auth\RegisterController@register');
});

生成 Controller

php artisan make:controller Api/Auth/LoginController
php artisan make:controller Api/Auth/RegisterController  

__ 数据库配置 .env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=51tbk.com
DB_USERNAME=root
DB_PASSWORD=123

如果不适用laravel 自带的认证系统（php artisan make:auth）会创建模板，可以使用数据迁移

php artisan make:model User -m   //生成user 模型的同时，创建数据迁移
单独生成迁移文件
php artisan make:migration create_users_table

修改内容

public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name')->unique();
        $table->string('email')->unique();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });
}

生成表

php artisan migrate

编辑 Model/Users.php

<?php

namespace App\Model;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Tymon\JWTAuth\Contracts\JWTSubject;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Users extends Authenticatable implements JWTSubject 
{
	use Notifiable;

	protected $fillable = ['name','email','password'];

	protected $hidden = ['password','remember_token'];

	public function getJWTIdentifier(){
        return $this->getKey();
    }

    public function getJWTCustomClaims(){
        return [];
    }
}

__ 注册 RegisterController.php

<?php

namespace App\Http\Controllers\Api\Auth;

use App\Http\Controllers\Controller;
use App\User;
use Dingo\Api\Routing\Helpers;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
use Tymon\JWTAuth\Facades\JWTAuth;

class RegisterController extends Controller {
	use RegistersUsers;
	use Helpers;

	public function register(Request $request) {

		$validator = $this->validator($request->all());
		if ($validator->fails()) {
			throw new StoreResourceFailedException("Validation Error", $validator->errors());
		}

		$user = $this->create($request->all());

		if ($user->save()) {

			$token = JWTAuth::fromUser($user);

			return $this->response->array([
				"token" => $token,
				"message" => "注册成功",
				"status_code" => 201,
			]);
		} else {
			return $this->response->error("User Not Found...", 404);
		}
	}

	protected function validator(array $data) {
		return Validator::make($data, [
			'name' => 'required|unique:users',
			'email' => 'required|email|max:255|unique:users',
			'password' => 'required|min:6',
		]);
	}

	protected function create(array $data) {
		return User::create([
			'name' => $data['name'],
			'email' => $data['email'],
			'password' => bcrypt($data['password']),
		]);
	}
}

__ 登录 LoginController.php

<?php

use App\Http\Controllers\Controller;
use App\User;
use Dingo\Api\Routing\Helpers;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException;
use Tymon\JWTAuth\Facades\JWTAuth;

class LoginController extends Controller
{
	use AuthenticatesUsers;
	use Helpers;

	public function login(Request $request) {

		$user = User::where('email', $request->email)->orWhere('name', $request->email)->first();

		if ($user && Hash::check($request->get('password'), $user->password)) {
			$token = JWTAuth::fromUser($user);
			return $this->sendLoginResponse($request, $token);
		}

		return $this->sendFailedLoginResponse($request);
	}

	public function sendLoginResponse(Request $request, $token) {
		$this->clearLoginAttempts($request);

		return $this->authenticated($token);
	}

	public function authenticated($token) {
		return $this->response->array([
			'token' => $token,
			'status_code' => 200,
			'message' => 'User Authenticated',
		]);
	}

	public function sendFailedLoginResponse() {
		throw new UnauthorizedHttpException("Bad Credentials");
	}

	public function logout() {
		$this->guard()->logout();
	}
}

__ 获取用户信息 routes/api.php

$api->group(['middleware' => 'api.auth'], function ($api) {
    $api->get('user', 'App\Http\Controllers\Api\UsersController@index');
});

php artisan make:controller Api/UsersController

编辑 UsersController.php

每次请求需要加 Header

Authorization ：Bearer + token
