NextAuthCredentialsProviderJWT/會話回呼-有解無憂

我在將令牌傳遞給會話回呼時遇到了一些困難。我的最終目標是將登錄用戶資料發送到客戶端。最初我只是發回用戶的電子郵件，但現在我希望將用戶的用戶名和姓名與電子郵件一起發送。通過遵循檔案，我們必須傳遞 JWT 和 Session 回呼，以便我們的開發人員能夠訪問令牌中的更多資料。目前，在我的 JWT 回呼中，我能夠記錄用戶資料，非常棒。然而，當我嘗試在 Session 回呼中記錄資料時，我得到一個空的 {}。非常感謝任何提示。先感謝您。

import NextAuth from "next-auth/next";
import CredentialsProvider from "next-auth/providers/credentials";

// Helper Functions
import {
  connectToDatabase,
  comparePasswords,
} from "../../helper/HelperFunctions";

export default NextAuth({
  session: { jwt: true },
  providers: [
    CredentialsProvider({
      async authorize(credentials) {
        const client = await connectToDatabase();

        const userCollection = client.db().collection("users");

        const user = await userCollection.findOne({
          email: credentials.email,
        });

        // const userInfo = {
        //   firstName: user.firstName,
        //   lastName: user.lastName,
        //   email: user.email,
        //   userName: user.userName,
        // };

        // console.log(userInfo);

        if (!user) {
          client.close();

          throw new Error("No user found!");
        }

        const isValid = await comparePasswords(
          credentials.password,
          user.password
        );

        if (!isValid) {
          client.close();

          throw new Error("Invalid password");
        }

        client.close();

        if (user) {
          return {
            user,
          };
        } else {
          return null;
        }
      },
    }),
  ],
  callbacks: {
    async jwt({ token, user }) {
      // Persist the OAuth access_token to the token right after signin
      if (user) {
        token = user;
        console.log(token);
        // all of the user data is being logged, yet how to pass it down to session callback so i can use all the user data in the client?
      }
      return token;
    },
  },
  async session({ session, token, user }) {
    session.user = token;
    console.log(session.user);
    // nothing gets logged into the terminal?? WTF

    return session;
  },
});

uj5u.com熱心網友回復：

因為您正在使用：

import CredentialsProvider from "next-auth/providers/credentials";

那是next-auth v4。在新版本的 next-auth 中，此代碼不再有效：

 session: { jwt: true },

相反，您應該使用

session: {
    strategy: "jwt",
  },

然后在jwt回呼中

//   jwt callback is only called when token is created
async jwt({ token, user }) {
      if (user) {
        token = user;
        // token = user;
        token.user=user
      }
      return Promise.resolve(token);
    },

然后在session回呼中：

session: async ({ session, token }) => {
  // session callback is called whenever a session for that particular user is checked
 // in above function we created token.user=user
  session.user = token.user;
  // you might return this in new version
  return Promise.resolve(session)
},
