MissingSecret [MissingSecretError]：请在生产中定义一个“秘密”

Question

根据文档https://next-auth.js.org/configuration/options#secret，添加NEXTAUTH_SECRET作为环境变量，您不必定义此选项。

但在 vercel 制作中我仍然得到，

环境设置为NEXTAUTH_SECRET=MYSECRETSNAPBOOK

代码：

export default NextAuth({
  providers: [
    GoogleProvider({
      clientId: process.env.GOOGLE_CLIENT_ID,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET,
    }),
  ],
  pages: {
    signIn: '/auth/signin',
  },
  callbacks: {
    async session({ session, token, user }) {
      session.user.username = session.user.name
        .split(' ')
        .join('')
        .toLocaleLowerCase()

      session.user.uid = token.sub

      return session
    },
  },
})

Answer 1

这是修复方法，

1. 在 .env 文件（或你的 vercel env）中添加NEXT_PUBLIC_SECRET=anything（确保你有NEXT_PUBLIC_SECRET名称）

2. 在 [...nextauth].js 中添加秘密选项

providers: [//Your providers],

secret: process.env.NEXT_PUBLIC_SECRET

3. 确保您不使用 7beta 版本。升级或降级至 4.1.2 ( npm i next-auth@4.1.2)
