Lumen轻量级的框架，用来作API很合适，起码本人这么想。javascript
作API，能够配合Dingo/Api来搞。php
Dingo/Api可使用的用户认证方式有：java
须要用的工具备：laravel
API能够简单的分三个部分：git
因此，先从登陆开始。github
这里的API服务基于Lumen实现。Laravel的实现还没搞过，之后再说。数据库
1、Tymon/JWT-Auth安装json
一、Lumen环境下执行：bootstrap
composer require tymon/jwt-auth而后须要添加“JWTAuthServiceProvider”到 Provider List。在Laravel环境中配置放在config/app.php中，但在Lumen环境有些不一样。
二、在"bootstrap/app.php" 文件中，找到Register Service Providers一节，添加：app
$app->register('Tymon\JWTAuth\Providers\JWTAuthServiceProvider');
内容以下：
<?php
if ( ! function_exists('config_path'))
{
/**
* Get the configuration path.
*
* @param string $path
* @return string
*/
function config_path($path = '')
{
return app()->basePath() . '/config' . ($path ? '/' . $path : $path);
}
}
"autoload": {
...
"files": [
"app/helpers.php"
]
},
composer dump-autoload
最简单的办法是从/vendor/tymon/jwt-auth/src/config/config.php 复制一份到config/jwt.php。
由于lumen没有vendor:publish命令，因此，能够装basicit/lumen-vendor-publish来解决。
composer require basicit/lumen-vendor-publish
而后执行：
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\JWTAuthServiceProvider"
执行“php artisan jwt:generate ”生成secret。
五、Adding facades
a）bootstrap/app.php文件中去掉"$app->withFacades();"前的注释。
b）在这行下面添加“$app->configure('jwt');”，否则调用不到jwt的配置文件。
c）紧接着是facades。
class_alias('Tymon\JWTAuth\Facades\JWTAuth', 'JWTAuth');
/** This gives you finer control over the payloads you create if you require it.
* Source: https://github.com/tymondesigns/jwt-auth/wiki/Installation
*/
class_alias('Tymon\JWTAuth\Facades\JWTFactory', 'JWTFactory'); // Optional
七、在bootstrap/app.php文件中，查找Register Middleware 小节。去掉"routeMiddleware"的注释，修改为下面这样：
$app->routeMiddleware([
'jwt.auth' => Tymon\JWTAuth\Middleware\GetUserFromToken::class,
'jwt.refresh' => Tymon\JWTAuth\Middleware\RefreshToken::class,
]);
<pre name="code" class="php">// store, update, destory这些须要权限的操做所有须要通过认证。$app->group(['prefix' => 'projects', 'middleware' => 'jwt.auth'], function($app) { $app->post('/', 'App\Http\Controllers\ProjectsController@store'); $app->put('/{projectId}', 'App\Http\Controllers\ProjectsController@update'); $app->delete('/{projectId}', 'App\Http\Controllers\ProjectsController@destroy');}); // index, show这些则不须要$app->group(['prefix' => 'projects'], function ($app){ $app->get('/', 'App\Http\Controllers\ProjectsController@index'); $app->get('/{projectId}', 'App\Http\Controllers\ProjectsController@show');});
建一个路由“$app->post('auth/login', 'App\Http\Controllers\Auth\AuthController@postLogin');”
在“app/Http/Controllers/Auth/AuthController.php”中建立咱们的登陆代码。
示例以下：
<?php
namespace App\Http\Controllers\Auth;
use Illuminate\Http\Exception\HttpResponseException;
use JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Http\Response as IlluminateResponse;
class AuthController extends Controller {
/**
* Handle a login request to the application.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function postLogin(Request $request)
{
try
{
$this->validate($request, [
'email' => 'required|email|max:255', 'password' => 'required',
]);
}
catch (HttpResponseException $e)
{
return response()->json([
'error' => [
'message' => 'Invalid auth',
'status_code' => IlluminateResponse::HTTP_BAD_REQUEST
]],
IlluminateResponse::HTTP_BAD_REQUEST,
$headers = []
);
}
$credentials = $this->getCredentials($request);
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'));
}
/**
* Get the needed authorization credentials from the request.
*
* @param \Illuminate\Http\Request $request
* @return array
*/
protected function getCredentials(Request $request)
{
return $request->only('email', 'password');
}
}此时，用post方式提交一个登陆请求会获得json格式的返回值，里面就是登陆后得到的token.
{
"token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjEsImlzcyI6Imh0dHA6XC9cLzEyNy4wLjAuMTo4NFwvYXV0aFwvbG9naW4iLCJpYXQiOiIxNDQ2OTE4MjM3IiwiZXhwIjoiMTQ0NjkyMTgzNyIsIm5iZiI6IjE0NDY5MTgyMzciLCJqdGkiOiI1ZGY1Njk5OGYxMTc3MzlhMjQ4ZjgzNzUyZmQ2MTA1MiJ9.1FP8yXwlw_KHrx9NAFqQWPaq2c2LLq_vyuJgwI_EX9k"
}
也能够另外指定。具体请看jwt.php中"User Model namespace" 的设置。
也就是，建立"User" model，生成数据库表users。再插入几条用户记录，到此项目完成。
可是！！！这里有个问题，User Model有些内容必需要有。
以下：
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Auth\Authenticatable;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;
class User extends Model implements AuthenticatableContract, CanResetPasswordContract
{
use Authenticatable, CanResetPassword;
//use EntrustUserTrait; // add this trait to your user model
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'users';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = ['name', 'email', 'password'];
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = ['password', 'remember_token'];
}请跟本身的User Model对比一下。
出现以下错误通常都是User Model有问题。
Argument 1 passed to Illuminate\Auth\EloquentUserProvider::validateCredentials() must be an instance of Illuminate\Contracts\Auth\Authenticatable, instance of App\User given, called in C:\xampp\htdocs\APIs\vendor\illuminate\auth\Guard.php on line 390
另外，有条件的能够装个Postman。这个工具很是很是棒。
