## UNIAPP实战项目笔记62 第三方快捷登录,微信登录,QQ登录,微博登录前后端实现 ##

### 总体思路 ###

> 用户点击了快捷方式登录,信息是否要存储在数据库中?肯定的
> 
> 后端:  
> 1.新增接口  
> 2.新增字段  
> 前端  
> 1.点击哪一个快捷登录方式  
> 2.需要给后端传递数据

### 后端数据表 ###

CREATE TABLE `user` (
      `id` int(11) NOT NULL AUTO_INCREMENT,
      `userName` varchar(255) DEFAULT NULL,
      `userPwd` varchar(255) DEFAULT NULL,
      `phone` varchar(255) DEFAULT NULL,
      `imgUrl` varchar(255) DEFAULT NULL,
      `nickName` varchar(255) DEFAULT NULL,
      `token` varchar(255) DEFAULT NULL,
      `provider` varchar(255) DEFAULT NULL,
      `openid` varchar(255) DEFAULT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=MyISAM AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
