2019 年苹果推出了自己家的登陆,要求集成第三方登陆的app, 必须在2020年4月份前集成苹果登陆, 所以我们来简单说一说
-
废话不多说, 直接上代码
-
这里不采用苹果提供的Button, 只提供方法
要求:
- iOS13 或以上
- Xcode11
- enables
Sign in with Applefeatures on Apple developer website , 开启这个后, 你的开发者网站会默认也会开启Sign in with Apple

- 授权后就可以拿到 User ID / Identity token , app端不一定可以拿到用户的email , 假如用户在授权时选择隐藏就会没有, 但没事, 后端验证后可以拿到email, 苹果登陆app端还是比较简单的, 这里将获取到的数据丢给后端就可以了
- authorizationCode：授权code, 给授权码的验证使用的
后端Node 验证
- 苹果提供两种验证方式: 一种是基于JWT的算法验证，另外一种是基于授权码的验证
- 我们这里只要讲解 JWT
- 想了解JWT 的朋友请自行查阅
- 苹果公钥网站
