Electron Apple SignIn 登录

本人写博客，向来主张：代码要完整，代码可运行，文中不留下任何疑惑。

最讨厌写博客，代码只留下片段，文中关键的东西没写清楚。之前看了那么多文章，就是不告诉我clientId从哪来的。

官方资料地址：

一、网页客户端代码

clientId：这个会在下文中告诉你怎么来的

usePopup：如果设置为true，就会以弹框的方式打开苹果登录窗口。设置为false，你自己试试吧

redirectURI：这在usePopup=true时，没啥用

state：在各种页面跳转时会原样传递，你自己看着办

nonce：一个随机数，至于作用么，你自己猜，照着做就好

<!DOCTYPE html>

</script></html>

登录成功时，前端 AppleIDSignInOnSuccess事件中，打印的event参数值

二、服务器端代码

前端传递过来code和id_token，这是两个不同的校验方法

code是一种，不过在苹果登录中我不知道怎么用，我用的是id_token校验。

对于id_token，这就是JWT校验技术。

JWT的介绍，请看我用ChatGpt问的结果。

在JWT（JSON Web Token）中，id token是一种用于身份验证和认证的令牌。要验证id token的有效性，您可以遵循以下步骤：

解码id token：JWT由三部分组成，即头部、载荷和签名。使用Base64解码id token，您可以获取其中的头部和载荷信息。
验证签名：使用头部中提供的算法（通常是HMAC、RSA或ECDSA）和密钥，验证签名的正确性。您需要获取与签名算法相对应的密钥，并将其与头部和载荷一起使用相同的算法进行签名验证。如果签名验证失败，则表示id token被篡改过或者是伪造的。
验证令牌的有效期：在载荷中，id token包含了发行时间（issued time）和过期时间（expiration time）。您需要检查当前时间是否在有效期范围内。如果当前时间在过期时间之后，说明id token已过期，不能再继续使用。
校验接收者：在载荷中，id token还可以包含一个接收者（audience）字段，用于指定该令牌的预期接收者。您可以检查接收者字段是否与您的应用程序的标识符匹配，以确保id token只能被合法的接收者使用。
可选的附加校验：根据您的需求，您还可以进行其他的校验，例如验证签发者（issuer）字段、检查令牌是否被撤销等。

需要注意的是，为了保证安全性，您应该将密钥存储在安全的位置，并定期更换密钥以防止泄露和滥用。此外，使用受信任的JWT库来处理JWT的解码和验证操作，而不是自行编写代码，以确保正确性和安全性。

这段代码是关键，即验证id_token是否有效；也验证require部分的字段是否存在，是否一致。注意，如果验证不通过，这段代码会报Exception的，如果报了Exception说明id_token是无效的。
