laravel5.5 dingo/api+jwt-auth

因为laravel5.5 具有发现包功能,只要包做了兼容laravel5.5就可以不用在config/app.php添加额外代码了。

集成dingo/api

github:https://github.com/dingo/api

添加

"dingo/api": "2.0.0-alpha1",

到项目下的composer.json文件的require配置项,然后

composer update

生成配置文件到config/api.php:

php artisan vendor:publish --provider="Dingo\Api\Provider\LaravelServiceProvider"

在.env配置文件中,设置dingo/api相关配置:

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)
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

注意:.env配置文件是不能有空格和注释的!

dingo/api集成就完成

集成jwt教程

添加

"tymon/jwt-auth": "^1.0.0-rc.1"

到项目下的composer.json文件的require配置项,然后

composer update

然后发布微调配置文件

php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"

将会在config文件夹生成jwt.php文件

在config/jwt.php中,你可以配置以下选项:

  • ttl:token有效期(分钟)
  • refresh_ttl:刷新token时间(分钟)
  • algo:token签名算法
  • user:指向User模型的命名空间路径
  • identifier:用于从token的sub中获取用户
  • require_claims:必须出现在token的payload中的选项,否则会抛出TokenInvalidException异常
  • blacklist_enabled:如果该选项被设置为false,那么我们将不能废止token,即使我们刷新了token,前一个token仍然有效
  • providers:完成各种任务的具体实现,如果需要的话你可以重写他们
    • User —— providers.user:基于sub获取用户的实现
    • JWT —— providers.jwt:加密/解密token
    • Authentication —— providers.auth:通过证书/ID获取认证用户
    • Storage —— providers.storage:存储token直到它们失效

然后运行:

php artisan jwt:secret

github :https://github.com/tymondesigns/jwt-auth

jwt.php配置详解如下:

ttl:token有效期(分钟)
refresh_ttl:刷新token时间(分钟)
algo:token签名算法
user:指向User模型的命名空间路径
identifier:用于从token的sub中获取用户
require_claims:必须出现在token的payload中的选项,否则会抛出TokenInvalidException异常
blacklist_enabled:如果该选项被设置为false,那么我们将不能废止token,即使我们刷新了token,前一个token仍然有效
providers:完成各种任务的具体实现,如果需要的话你可以重写他们
User —— providers.user:基于sub获取用户的实现
JWT —— providers.jwt:加密/解密token
Authentication —— providers.auth:通过证书/ID获取认证用户
Storage —— providers.storage:存储token直到它们失效

至此,jwt集成就完成了。

创建Token

创建用户token最常用的方式就是通过登录实现用户认证,如果成功则返回相应用户的token。这里假设我们有一个AuthenticateController

use JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;

class AuthenticateController extends Controller
{
    public function authenticate(Request $request)
    {
        // grab credentials from the request
        $credentials = $request->only('email', 'password');

        try {
            // attempt to verify the credentials and create a token for the user
            if (! $token = JWTAuth::attempt($credentials)) {
                return response()->json(['error' => 'invalid_credentials'], 401);
            }
        } catch (JWTException $e) {
            // something went wrong whilst attempting to encode the token
            return response()->json(['error' => 'could_not_create_token'], 500);
        }

        // all good so return the token
        return response()->json(compact('token'));
    }
}

有时候我们还可以直接通过用户对象实例创建token:

// grab some user
$user = User::first();
$token = JWTAuth::fromUser($user);

此外,还可以使用Tymon\JWTAuth\PayloadFactory实例(或者JWTFactory门面)基于任意数据创建token:

$customClaims = ['foo' => 'bar', 'baz' => 'bob'];
$payload = JWTFactory::make($customClaims);
$token = JWTAuth::encode($payload);

还可以使用方法链的方式:

// add a custom claim with a key of `foo` and a value of ['bar' => 'baz']
$payload = JWTFactory::sub(123)->aud('foo')->foo(['bar' => 'baz'])->make();
$token = JWTAuth::encode($payload);

用户认证

用户登录成功之后,下一步就是发送一个包含token的请求来获取用户信息。

要通过http发送一个需要认证通过的请求,需要设置Authorization头:

Authorization: Bearer {yourtokenhere}

如果用户名/密码没有进行base64编码那么Apache似乎会摒弃Authorization头,要修复这一问题你可以添加如下代码到Apache配置文件:

RewriteEngine On
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]

或者将token信息包含到URL中:

http://api.mysite.com/me?token={yourtokenhere}

要从请求中获取token,你可以这么做:

// this will set the token on the object
JWTAuth::parseToken();// and you can continue to chain methods
$user = JWTAuth::parseToken()->authenticate();

要获取该token值,你可以这么调用:

$token = JWTAuth::getToken();

如果token被设置则会返回,否则会尝试使用方法从请求中解析token,如果token未被设置或不能解析最终返回false。

当然如果需要的话你还可以手动设置token:

JWTAuth::setToken('foo.bar.baz');

从Token中获取认证用户:

// somewhere in your controller
public function getAuthenticatedUser()
{
    try {
        if (! $user = JWTAuth::parseToken()->authenticate()) {
            return response()->json(['user_not_found'], 404);
        }
    } catch (Tymon\JWTAuth\Exceptions\TokenExpiredException $e) {
        return response()->json(['token_expired'], $e->getStatusCode());
    } catch (Tymon\JWTAuth\Exceptions\TokenInvalidException $e) {
        return response()->json(['token_invalid'], $e->getStatusCode());
    } catch (Tymon\JWTAuth\Exceptions\JWTException $e) {
        return response()->json(['token_absent'], $e->getStatusCode());
    }

    // the token is valid and we have found the user via the sub claim
    return response()->json(compact('user'));
}

jwt-auth扩展还提供了两个中间件GetUserFromTokenRefreshToken,前者用于在请求头和参数中检查是否包含token,并尝试对其解码,后者会再次从请求中解析token,并顺序刷新token(同时废弃老的token)并将其作为下一个响应的一部分。要使用这两个中间件,需要到app/Http/Kernel.php下的$routeMiddleware属性中注册它们:

protected $routeMiddleware = [
    ...
    'jwt.auth' => 'Tymon\JWTAuth\Middleware\GetUserFromToken',
    'jwt.refresh' => 'Tymon\JWTAuth\Middleware\RefreshToken',
];

JWT让用户认证变得简单和安全,token会被保存到本地的storage/web或Cookie中,使用JWT,基于API的用户认证将不再困难。

测试dingo/api 和 jwt:

在routes/api.php文件添加:

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

// 配置api版本和路由
$api->version('v1', ['namespace' => 'App\Http\Api\V1\Controllers'], function ($api) {

    // 授权组
    $api->group(['prefix' => 'auth'], function ($api) {
        //$api->post('register', 'AuthenticateController@register')->name('auth.register');

        $api->post('register', 'AuthController@register');
        $api->post('login', 'AuthController@login');
        $api->post('logout', 'AuthController@logout');
        $api->post('refresh', 'AuthController@refresh');
        $api->post('me', 'AuthController@me');
        $api->get('test', 'AuthController@test');
    });

    $api->get('test/testapi', 'UserController@test')->name('test');
    $api->get('test/testjwt', 'UserController@testjwt')->name('testjwt');
    $api->get('users/{id}', 'UserController@getUserInfo')->name('getUserInfo');
});

文件路径:App\Http\Api\V1\Controllers\AuthController.php

文件路径:App\User.php 需要implements JWTSubject

<?php

namespace App;

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

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',
    ];


    // Rest omitted for brevity

    /**
     * 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 [];
    }
}

记得要在config/auth.php修改

//设置默认使用的guard,此处设置为api时,laravel 默认的auth登录则无法登录成功哦,设置为web才行
    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'jwt',
            'provider' => 'users',
        ],
    ],
