NextAuth Credentials 在成功获取数据后返回 null

Question

目前我无法在我的系统中实现next-auth 凭据提供程序。

我正在使用axios（到不同的本地主机）验证凭据（电子邮件和密码）。

• Nextjs 系统运行在http://localhost:3000
• 节点服务器运行在http://localhost:5400

这些是我目前面临的问题：-

1. 成功登录后，我被重定向到http://localhost:5400（空白屏幕）。即使我从系统中logout 也是如此。它仍然将我重定向到相同的网址。
2. 即使在成功登录之后，user 也会返回null。我从session 获得的唯一数据是expires

我现在的代码：-

• 演示按钮调用signIn & signOut:-

// in homepage (pages/home.js)
import { signIn, signOut, useSession } from 'next-auth/client'

export default Homepage = () => {
  const [ session ] = useSession()  
  console.log(session) 
  // returns 'null' (when not login yet)
  // returns { expires: "2021-06-28T08:59:47.504Z", user: { name: null, email: null, image: null, _proto_: Object }, _proto_: Object } after successful login  

  return (
    <>
       {!session ? 
        <>
          Sign-in to continue
          <button onClick={() => {
            signIn('credentials', 
            { 
              email: 'mohdfathi_mhdnoor@yahoo.com', 
              password: 'qwer1234', 
              callbackUrl: `${window.location.origin}/about` 
            })
            }}>SignIn</button>
        </> 
      :
        <>
          {session.user.email}
          <button onClick={() => signOut()}>SignOut</button>
        </>
      
      }
    </>
}

• [...nextauth].js:-

import axios from 'axios'
import NextAuth from 'next-auth'
import Providers from 'next-auth/providers'
import { config } from '../../../src/utils/Header'

export default NextAuth({
  providers: [
    Providers.Credentials({
      name: 'Portfolio V4 Credentials',
      credentials: {
        email: { label: "Email", type: "email", placeholder: "Please enter an email" },
        password: { label: "Password", type: "password", placeholder: "Please enter a password" }
      },
      async authorize(credentials, req) {
        try {
          const res = await axios.post(
            process.env.REACT_APP_SERVER_ENDPOINT_HOST + "/api/auth/callback/credentials", 
            { uid: '', email: credentials.email, password: credentials.password },
            config
          )
          const user = await res
          
          if (user.data.success) {
            console.log(user.data) // this logouts { success: true, data: { uid: '5f8fc26c6a103b243428bec1', sato: 1622295126589 } }
            return user.data
          }
        } catch (e) {
          console.log('Error: ')
          console.log(e)
          return null
        }
      }
    })
  ]
})

我确实将user 的内容更改为我从server 获得的内容。但它根本没有反映上面session I console.log 中的内容。还是console.log:-

{
  expires: "2021-06-28T08:59:47.504Z",
  user: {
    email: null,
    image: null,
    name: null,
    _proto_: Object
  },
  _proto_: Object
}

Next-Auth | When user object have too many items then session request is without data

查看该链接下的代码。你需要的是回调函数。
