Laravel 5.5+ Dingo +Jwt 快速搭建 API系統

剛進入新公司，比較忙，只能抽時間來寫寫比較簡短的博文總結，還望見諒。
    最近公司要從實業轉型線上，決定用laravel 來作快速開發，而一些同事以前沒有用過laravel，尤爲是api 的快速搭建，一致想讓我把搭建過程給分享出來，此爲背景

搭建過程記錄 laravel 5.5
__
建立 laravel 項目

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

__
安裝 Dingo

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

執行安裝

composer update

安裝jwt

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

配置項目
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
]

發佈配置文件 : 終端執行

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 
選擇編號便可發佈

生成 JWT_SECRET 寫入.env

php artisan jwt:secret

config/api.php

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

在 .env 中，把 dingo 配置在最後

API_STANDARDS_TREE=vnd // 環境
API_SUBTYPE=myapp // 子類型
API_PREFIX=api // 前綴
API_DOMAIN=api.myapp.com //子域名  （前綴和子域名只能存在一個）可選
API_VERSION=v1 // 版本
API_NAME=My API // 名字（使用API Blueprint命令纔會用到）
API_CONDITIONAL_REQUEST=false // 帶條件的請求
API_STRICT=false // Strict模式
API_DEFAULT_FORMAT=json // 響應格式
API_DEBUG=true // 調試模式

上面的配置不是都是必要的，可根據實際狀況進行選擇（上面配置時參考網絡配置）,如：

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

__

路由：
在routers/api.php中新建內容，兩個路徑分別是註冊和登陸：

//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

__
數據庫配置 .env

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

若是不適用laravel 自帶的認證系統（php artisan make:auth）會建立模板，能夠使用數據遷移

php artisan make:model User -m   //生成user 模型的同時，建立數據遷移
單獨生成遷移文件
php artisan make:migration create_users_table

修改內容

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

編輯 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 [];
    }
}

__
註冊 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" => "註冊成功",
                "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']),
        ]);
    }
}

__
登陸 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();
    }
}

__
獲取用戶信息
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

編輯 UsersController.php

每次請求須要加 Header

Authorization ：Bearer + token
