Question

我正在将React与MongoDB和MongoDB Stitch无服务器后端作为服务一起使用。我已经进行了Google登录，并遵循了MongoDB教程中的教程。

https://docs.mongodb.com/stitch/tutorials/guides/todo-guide-google/

因为我希望用户也提供额外的数据。我创建了一个名为用户的自定义数据表，该表已与owner_id字段链接到登录的用户。我关注了文档，此方法工作正常。

当用户在currentuser对象上登录名为customData的属性时，该属性将包含额外的数据。但是，一旦页面刷新发生，当前用户的所有数据仍然可用，但customData对象为空。

是否可以将customData保留在currentUser上。还是MongoDB Stitch登录后仅提供一次用户的customData？

export const StitchAuthProvider = ({ children }) => {
  const [authState, setAuthState] = useState({
    isLoggedIn: hasLoggedInUser(),
    currentUser: getCurrentUser()
  });

  useEffect(() => {
    const authListener = {
      onUserLoggedIn: (auth, loggedInUser) => {
        if (loggedInUser) {
          setAuthState(authState => ({
            ...authState,
            isLoggedIn: true,
            currentUser: loggedInUser
          }));
          if (!loggedInUser.customData._id) {
            try {
              users.insertOne({
                owner_id: loggedInUser.id,
                ...loggedInUser.profile.data
              });
            } catch (error) {
              console.error("aaaaah Ik messed up!", error);
            }
          }
        }
      },
      onUserLoggedOut: (auth, loggedOutUser) => {
        setAuthState(authState => ({
          ...authState,
          isLoggedIn: false,
          currentUser: null
        }));
      }
    };
    addAuthenticationListener(authListener);
    handleOAuthRedirects();
    setAuthState(state => ({ ...state }));
    return () => {
      removeAuthenticationListener(authListener);
    };

    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, []);

  // Authentication Actions
  const handleLogin = async provider => {
    if (!authState.isLoggedIn) {
      switch (provider) {
        case "anonymous":
          return loginAnonymous();
        case "google":
          return loginGoogle();
        default: {
        }
      }
    }
  };

  const handleLogout = async () => {
    const { isLoggedIn } = authState;
    if (isLoggedIn) {
      await logoutCurrentUser();
      setAuthState({
        ...authState,
        isLoggedIn: false,
        currentUser: null
      });
    } else {
      console.log(`can't handleLogout when no user is logged in`);
    }
  };

  const authInfo = useMemo(
    () => {
      const { isLoggedIn, currentUser } = authState;
      // TODO: remove logger
      console.log(currentUser);
      const value = {
        isLoggedIn,
        currentUser,
        actions: { handleLogin, handleLogout }
      };
      return value;
    },
    // eslint-disable-next-line react-hooks/exhaustive-deps
    [authState.isLoggedIn]
  );

页面刷新后，MongoDB Stitch链接的CustomData丢失了
