详解Laravel制作API接口（laravel写api接口）

需要注意的是：API有它的具体用途，我们应该清楚它是干啥的。访问API的时候应该输入什么。访问过API过后应该得到什么。

在开始设计API时，我们应该注意这8点。后续的开发计划就围绕着这个进行了。

1.Restful设计原则

2.API的命名

3.API的安全性

4.API返回数据

5.图片的处理

6.返回的提示信息

7.在线API测试文档

8.在app启动时，调用一个初始化API获取必要的信息

用laravel开发API

就在我上愁着要不要从零开始学习的时候，找到了这个插件dingo/api那么现在就来安装吧！

首先一定是下载的没错

在新安装好的laravel的composer.json加入如下内容

然后打开cmd执行

composer update

在config/app.php中的providers里添加

App\Providers\OAuthServiceProvider::class, Dingo\Api\Provider\LaravelServiceProvider::class, LucaDegasperi\OAuth2Server\Storage\FluentStorageServiceProvider::class, LucaDegasperi\OAuth2Server\OAuth2ServerServiceProvider::class,

在aliases里添加

'Authorizer' => LucaDegasperi\OAuth2Server\Facades\Authorizer::class,

修改app/Http/Kernel.php文件里的内容

protected $middleware = [\LucaDegasperi\OAuth2Server\Middleware\OAuthExceptionHandlerMiddleware::class, ]; protected $routeMiddleware = [ 'oauth' => \LucaDegasperi\OAuth2Server\Middleware\OAuthMiddleware::class, 'oauth-user' => \LucaDegasperi\OAuth2Server\Middleware\OAuthUserOwnerMiddleware::class, 'oauth-client' => \LucaDegasperi\OAuth2Server\Middleware\OAuthClientOwnerMiddleware::class, 'check-authorization-params' => \LucaDegasperi\OAuth2Server\Middleware\CheckAuthCodeRequestMiddleware::class, 'csrf' => \App\Http\Middleware\VerifyCsrfToken::class, ];

然后执行

php artisan vendor:publish php artisan migrate

在.env文件里添加这些配置

API_STANDARDS_TREE=x API_SUBTYPE=rest API_NAME=REST API_PREFIX=api API_VERSION=v1 API_CONDITIONAL_REQUEST=true API_STRICT=false API_DEBUG=true API_DEFAULT_FORMAT=json

修改app\config\oauth2.php文件

'grant_types' => [ 'password' => [ 'class' => 'League\OAuth2\Server\Grant\PasswordGrant', 'access_token_ttl' => 604800, 'callback' => '\App\Http\Controllers\Auth\PasswordGrantVerifier@verify', ], ],

新建一个服务提供者，在app/Providers下新建OAuthServiceProvider.php文件内容如下

namespace App\Providers; use Dingo\Api\Auth\Auth; use Dingo\Api\Auth\Provider\OAuth2; use Illuminate\Support\ServiceProvider; class OAuthServiceProvider extends ServiceProvider { public function boot() { $this->app[Auth::class]->extend('oauth', function ($app) { $provider = new OAuth2($app['oauth2-server.authorizer']->getChecker()); $provider->setUserResolver(function ($id) { // Logic to return a user by their ID. }); $provider->setClientResolver(function ($id) { // Logic to return a client by their ID. }); return $provider; }); } public function register() { // } }

然后打开routes.php添加相关路由

//Get access_token Route::post('oauth/access_token', function() { return Response::json(Authorizer::issueAccessToken()); }); //Create a test user, you don't need this if you already have. Route::get('/register',function(){ $user = new App\User(); $user->name="tester"; $user->email="test@test.com"; $user->password = \Illuminate\Support\Facades\Hash::make("password"); $user->save(); }); $api = app('Dingo\Api\Routing\Router'); //Show user info via restful service. $api->version('v1', ['namespace' => 'App\Http\Controllers'], function ($api) { $api->get('users', 'UsersController@index'); $api->get('users/{id}', 'UsersController@show'); }); //Just a test with auth check. $api->version('v1', ['middleware' => 'api.auth'] , function ($api) { $api->get('time', function () { return ['now' => microtime(), 'date' => date('Y-M-D',time())]; }); });

分别创建BaseController.php和UsersController.php内容如下

//BaseController namespace App\Http\Controllers; use Dingo\Api\Routing\Helpers; use Illuminate\Routing\Controller; class BaseController extends Controller { use Helpers; } //UsersController namespace App\Http\Controllers; use App\User; use App\Http\Controllers\Controller; class UsersController extends BaseController { public function index() { return User::all(); } public function show($id) { $user = User::findOrFail($id); // 数组形式 return $this->response->array($user->toArray()); } }

随后在app/Http/Controllers/Auth/下创建PasswordGrantVerifier.php内容如下

namespace App\Http\Controllers\Auth; use Illuminate\Support\Facades\Auth; class PasswordGrantVerifier { public function verify($username, $password) { $credentials = [ 'email' => $username, 'password' => $password, ]; if (Auth::once($credentials)) { return Auth::user()->id; } return false; } }

打开数据库的oauth_client表新增一条client数据

INSERT INTO 'oauth_clients' ('id', 'secret', 'name', 'created_at', 'updated_at') VALUES ('1', '2', 'Main website', '2016–03–13 23:00:00', '0000–00–00 00:00:00');

随后的就是去愉快的测试了，这里要测试的API有

新增一个用户

http://localhost/register

读取所有用户信息

http://localhost/api/users

只返回用户id为4的信息

http://localhost/api/users/4

获取access_token

http://localhost/oauth/access_token

利用token值获得时间，token值正确才能返回正确值

http://localhost/api/time

打开PostMan
