lumen Rest API 起步
修改项目文件
.env
DB_DATABASE=<数据库名>
DB_USERNAME=<数据库用户名>
DB_PASSWORD=<数据库密码>
bootstrap/app.php
$app->withFacades();
$app->withEloquent();
数据库迁移
创建数据表
php artisan make:migration create_table_users --create=users
定义数据表
database/migrations/迁移文件
Schema::create('users', function (Blueprint $table) {
$table->id();
$table->string('name');
});
运行迁移
php artisan migrate
创建模型
接下来我们在app目录下创建模型文件User.php
namespace App;
use IlluminateAuthAuthenticatable;
use IlluminateContractsAuthAccessAuthorizable as AuthorizableContract;
use IlluminateContractsAuthAuthenticatable as AuthenticatableContract;
use IlluminateDatabaseEloquentModel;
use LaravelLumenAuthAuthorizable;
class User extends Model implements AuthenticatableContract, AuthorizableContract
{
use Authenticatable, Authorizable;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $table = 'users';
protected $fillable = [
'id', 'name',
];
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = [];
public $timestamps = false;
}
创建控制器
然后创建控制器文件app/Http/Controllers/UserController.php
namespace AppHttpControllers;
use AppUser;
use DB;
use IlluminateHttpRequest;
class UserController extends Controller
{
public function createUser(Request $request)
{
$user = User::create($request->all());
return response()->json($user);
}
public function updateUser(Request $request,$id)
{
$user = User::find($id);
$user->name = $request->input('name');
$user->save();
return response()->json($user);
}
public function deleteUser($id)
{
$user = User::find($id);
$user->delete();
return response()->json('删除成功');
}
public function index($id = null)
{
if (!empty($id)) {
$users = User::find($id);
}else{
$users = User::all();
}
return response()->json($users);
}
public function hello()
{
return 'hello';
}
}
定义路由
修改文件bootstrap/app.php
$app->router->group([
'namespace' => 'AppHttpControllers',
], function ($router) {
require __DIR__.'/../routes/web.php';
require __DIR__.'/../app/Http/routes.php';
});
return $app;
打开app/Http/routes.php并添加路由
$router->get('/hello', array(
'uses' => 'UserController@hello'
));
$router->group(['prefix' => 'api'], function() use ($router){
$router->post('person', 'UserController@createUser');
$router->put('person/{id}','UserController@updateUser');
$router->delete('person/{id}','UserController@deleteUser');
$router->get('person[/{id}]','UserController@index');
});
测试API
curl -i -X POST -H "Content-Type:application/json" http://www.lelumen.test/api/person -d '{"id":2,"name":"test1"}'
curl -i -X POST -H "Content-Type:application/json" http://www.lelumen.test/api/person -d '{"name":"test22"}'
curl -H "Content-Type:application/json" http://www.lelumen.test/api/person/1 -X PUT -d '{"name":"ttt"}'
curl -H "Content-Type:application/json" http://www.lelumen.test/api/person -X GET
curl -H "Content-Type:application/json" http://www.lelumen.test/api/person/1 -X GET
curl -X DELETE http://www.lelumen.test/api/person/1
