类型错误：options.providers 在下一步身份验证中不可迭代

Question

因此，我一直在尝试将 Next Auth 集成到全栈 NextJS Web 应用程序中。我已经使用 JWT 处理了登录，并且由于使用带有 Next Auth 的凭证登录类型，因此将会话存储在浏览器上。我已经设法让登录正常工作，但是我现在正在尝试保护我的 API 路由以从 MongoDB 检索用户的基本数据。相关文件如下，但是，我遇到了一个错误unstable_getServerSession()（至少根据跟踪），该错误表明options.providers不可迭代。我无法理解这一点，因为我已将其创建为数组......

任何帮助将不胜感激！

import NextAuth from 'next-auth';
import CredentialsProvider from 'next-auth/providers/credentials';
import clientPromise from '../../../lib/mongodb'

        strategy: "jwt"
    },

            async authorize(credentials, req) {

我知道，同样的错误重复了三次，也不知道为什么会发生......

您必须单独导出 authOptions 并将它们作为export default NextAuth(authOptions)参数应用到 。

这是您的代码的解决方案：

export const authOptions = {
    session: {
        strategy: "jwt"
    },
    providers: [
        CredentialsProvider({
            name: "Email and Password",
            credentials: {
                email: { label: "Email", type: "email", placeholder: "Email Address" },
                password: { label: "Password", type: "password", placeholder: "Password" }
            },
            async authorize(credentials, req) {
                const db = (await clientPromise).db();
                const employees = db.collection('employees');
                const res = await employees.findOne({
                    email: credentials.email
                });
                if (!res) {
                    throw new Error('No user found with those details');
                }
                const checkPassword = await compare(credentials.password, res.password);
                if (!checkPassword) {
                    throw new Error('Incorrect username or password');
                }
                return res;
            }
        }),
    ],
    pages: {
        signIn: "/signin"
    }
}

export default NextAuth(authOptions)
