创建控制器（创建完成之后生成的文件在 app/Http/Controllers/ 下）
>php artisan make:controller AuthController
>php artisan make:controller RecipeController
添加路由 （路径：routes/api.php）
<?php
Route::post('/register', 'AuthController@register');
Route::post('/login', 'AuthController@login');
Route::post('/logout', 'AuthController@logout');
Route::resource('recipes', 'RecipeController');
修改 AuthController.php 控制器
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\User;
use Hash;
class AuthController extends Controller
{
public function __construct()
{
$this->middleware('auth:api')->only('logout');
}
public function register(Request $request){
$this->validate($request, [
'name' => 'required|max:255',
'email' => 'required|email|unique:users',
'password' => 'required|between:6,25|confirmed'
]);
$user = new User($request->all());
$user->password = bcrypt($request->password);
$user->save();
return response()->json([
'registered' => true
]);
}
public function login(Request $request){
$this->validate($request, [
'email' => 'required|email',
'password' => 'required|between:6,25'
]);
$user = User::where('email', $request->email)->first();
if($user && Hash::check($request->password, $user->password)){
$user->api_token = str_random(60);
$user->save();
return response()->json([
'authenticated' => true,
'api_token' => $user->api_token,
'user_id' => $user->id
]);
}
return response()->json([
'email' => '提供的电子邮件和密码不匹配!'
], 422);
}
public function logout(Request $request){
$user = $request->user();
$user->api_token = null;
$user->save();
return response()->json(['logged_out' => true]);
}
}
