laravel 5.4 + dingo api + jwt

composer create-project --prefer-dist laravel/laravel myApi
安装dingo api
在composer.json中添加

composer require dingo/api:1.0.x@dev
在config/app.php

'providers' => [
//前面很多
Dingo\Api\Provider\LaravelServiceProvider::class,
]
发布配置文件
终端运行

php artisan vendor:publish --provider="Dingo\Api\Provider\LaravelServiceProvider"
打开.env文件，把dingo的配置放到最后面

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
下面是我的配置：

API_STANDARDS_TREE=vnd
API_SUBTYPE=emall
API_PREFIX=api
API_VERSION=v1
没必要每个都配上去，主要的配一下就可以了

安装jwt
还是composer.json

"require-dev": {
"tymon/jwt-auth": "1.0.*"
},
"minimum-stability": "dev",
"prefer-stable": true
其实只需要加上，下面是我的写法，上面是国外的写法

"tymon/jwt-auth": "1.0.*@dev"
运行composer update将dingo和jwt装上去

添加jwt的认证
在config/api.php添加内容

'auth' => [
'jwt' => Dingo\Api\Auth\Provider\JWT::class
]
在config/app.php

'providers' => [
// 前面很多
Tymon\JWTAuth\Providers\LaravelServiceProvider::class
],

'aliases' => [
// 前面很多
'JWTAuth' => Tymon\JWTAuth\Facades\JWTAuth::class
]
在终端运行：

php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"
会生成config/jwt.php 这是jwt的配置文件

生成jwt的key到.env文件运行：

php artisan jwt:secret

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

//这句接管路由
$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');

});
生成两个controller
终端输入：

php artisan make:controller App\\Http\\Api\\Auth\\LoginController
php artisan make:controller App\\Http\\Api\\Auth\\RegisterController
数据库
备置.env文件

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=databasename
DB_USERNAME=root
DB_PASSWORD=
添加迁移文件，当然你也可以使用php artisan make:auth 安装LV自带的用户
下面我们用新建的吧
终端运行：

php artisan make:model User -m
此命令可以添加迁移文件同时添加Model
迁移文件一般在database/migrations/时间格式_create_users_table.php
打开迁移文件修改以下内容:

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();
});
}
终端运行：php artisan migrate创建users表

打开我们新建的Model在App/下User.php
添加如下内容：

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

class User extends Authenticatable implements JWTSubject
{
use Notifiable;

/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'name', 'email', 'password',
];

/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];

/**
* Get the identifier that will be stored in the subject claim of the JWT.
*
* @return mixed
*/
public function getJWTIdentifier()
{
return $this->getKey();
}

/**
* Return a key value array, containing any custom claims to be added to the JWT.
*
* @return array
*/
public function getJWTCustomClaims()
{
return [];
}
}
注册
在之前建的App/Http/Controller/Api/Auth/RegisterController.php
添加如下内容：

use App\Http\Controllers\Controller;
use App\User;
use Dingo\Api\Exception\StoreResourceFailedException;
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){

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

return $this->response->array([
"token" => $token,
"message" => "User created",
"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
在之前建的App/Http/Controller/Api/Auth/LoginController.php

use App\User;
use Dingo\Api\Routing\Helpers;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
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();
}
}
拉取用户信息
在routers/api.php添加

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

php artisan make:controller App\\Http\\Controllers\\Api\\UsersController
在UsersController.php中添加

namespace App\Http\Controllers\Api;

use Dingo\Api\Routing\Helpers;
use Illuminate\Routing\Controller;

class UsersController extends Controller
{
use Helpers;

public function __construct()
{
$this->middleware('api.auth');
}
public function index(){
//        return User::all();
$user = $this->auth->user();

return $user;
}
}
