# QuickAuthLogin-WP
wechat login plugin for WordPress
基于[QuickAuth](https://qauth.cn)扫码登录平台开发的WordPress微信扫码登录插件
## 起始
本插件是基于 QuickAuth 开发的 插件，使用前需要进入[QuickAuth平台](https://qauth.cn)注册配置自己的应用
如需修改插件或开发自己的接入项目，请参考 [QuickAuth接入文档](https://qauth.cn/doc/index.html)
插件地址：[https://github.com/mr-wixy/QuickAuthLogin-WP](https://github.com/mr-wixy/QuickAuthLogin-WP)
下载地址：[QuickAuthLogin.zip][1]
(请勿与其它同类插件同时启用，以免互相影响)
## 使用方法
第 1 步：下载本插件，解压，放到 `wp-content/plugins` 目录中；
第 2 步：登录管理后台，激活插件；
第 3 步：登录QuickAuth网站创建接入应用；
![](https://cdn.wixy.cn/blog-picture/blog-picture20220127160420.png)
第 4 步：填写应用的基本信息（注意：此时可以获取到AppKey，回调地址请填写自己博客的域名+/index.php/wp-json/wp/v2/qauth_login 此处必须为https）
![](https://cdn.wixy.cn/blog-picture/20220207150311.png)
第 5 步：发布应用；
![发布应用](https://cdn.wixy.cn/blog-picture/blog-picture20220127161055.png)
第 6 步：[获取](https://qauth.cn/config/secret)UserSecretKey；
![](https://cdn.wixy.cn/blog-picture/blog-picture20220127161157.png)
第 7 步：进入博客插件后台配置AppKey和UserSecret；
![](https://cdn.wixy.cn/blog-picture/20220207145540.png)
第 8 步：进入博客后台绑定管理员微信账号；

## 重要说明
1. QuickAuthApi 默认配置，正常情况下无需修改（除非QuickAuth网站接口地址改了）
2. 未绑定用户自动注册 开启后，未绑定的微信扫码则会自动注册账号
