laravel——JWT 二次使用記錄

#項目環境
laravel5.8   php7.1.3

#安裝擴展
composer require "tymon/jwt-auth:1.0.0" #選擇版本安裝

#編輯 config/app.php
#providers 中添加
Tymon\JWTAuth\Providers\JWTAuthServiceProvider::class,

#aliases 添加
 'JWTAuth'=> Tymon\JWTAuth\Facades\JWTAuth::class,
 'JWTFactory'=> Tymon\JWTAuth\Facades\JWTFactory::class

#發佈JWT的配置文件
php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\JWTAuthServiceProvider"

#生成JWT Key
php artisan jwt:secret

#創建User模型
php artisan make:model  Models/User

#編輯User模型
<?php
