Expo/React Native 对接Firebase后端实现Microsoft OAuth认证的问题求助

我目前在基于Expo Dev Client的React Native纯JS项目（仅Android平台）中，尝试通过Firebase实现Microsoft OAuth认证，但一直卡在**「unmatched route（不匹配路由）」**的问题上：Microsoft返回的带长哈希参数的回调链接，总是被Expo的路由机制拦截报错。

我已经试过react-native-app-auth、react-native-firebase/auth，还有expo-auth-session相关方法，也有人提醒我不要使用Web SDK，毕竟是React Native原生环境。我确认重定向URI是正确的，现在核心需求就是能顺利拿到令牌并传给Firebase，麻烦各位帮忙排查下我的代码问题！

我的认证逻辑代码（MicrosoftAuthService.js） #

import auth from "@react-native-firebase/auth";
import * as AuthSession from "expo-auth-session";
import * as WebBrowser from "expo-web-browser";

WebBrowser.maybeCompleteAuthSession();

export const signInWithMicrosoft = async () => {
  try {
    const discovery = await AuthSession.fetchDiscoveryAsync(
      "https://login.microsoftonline.com/common/v2.0",
    );

    // 尝试用makeRedirectUri解决「unmatched route」错误
    const redirectUri = AuthSession.makeRedirectUri({
      scheme: "msauth",
      path: "com.clouddropdesigns.vibenmed/Xo8WBi6jzSxkDVR4drqm84yr9iU=",
    });

    const request = await AuthSession.loadAsync(
      {
        clientId: "client id",
        redirectUri: redirectUri,
        scopes: ["openid", "profile", "email", "offline_access"],
        responseType: AuthSession.ResponseType.IdToken,
        extraParams: {
          prompt: "select_account",
          nonce: Math.random().toString(36).substring(7),
        },
      },
      discovery,
    );

    const response = await request.promptAsync(discovery);

    if (response.type !== "success") {
      throw new Error("Microsoft sign-in dismissed or failed.");
    }

    const { id_token } = response.params;

    // 修正：Firebase RN的正确语法（凭证不需要用new关键字）
    const credential = auth.MicrosoftAuthProvider.credential(id_token);

    const userCredential = await auth().signInWithCredential(credential);

    return userCredential.user;
  } catch (error) {
    console.error("Login Error:", error);
    throw error;
  }
};

登录按钮组件代码 #

import { Image, Pressable, StyleSheet } from "react-native";
import { useDispatch, useSelector } from "react-redux";
import { setError, setSignIn, setUser } from "../../../redux/slices/auth.slice";

import { signInWithMicrosoft } from "../util/MicrosoftAuthService";

const MICROSOFT_LOGO = require("./ms-symbollockup_signin_dark.png");

const MicrosoftLoginButton = () => {
  const dispatch = useDispatch();
  const { user, signIn } = useSelector((state) => state.auth);

  const handleSignIn = async () => {
    try {
      const user = await signInWithMicrosoft();
      if (user) {
        dispatch(setSignIn(true));
        dispatch(setUser(user.uid)); // 现在直接返回用户对象
      }
    } catch (error) {
      dispatch(setError(error.message));
    }
  };

  return (
    <Pressable
      style={styles.btn}
      onPress={handleSignIn}
      accessibilityRole="button"
      accessibilityLabel="Sign in with Microsoft"
      accessibilityHint="Signs in to Med Alliance using Microsoft Account"
    >
      <Image source={MICROSOFT_LOGO} style={styles.img} resizeMode="contain" />
    </Pressable>
  );
};

export default MicrosoftLoginButton;

const styles = StyleSheet.create({
  btn: {
    width: 248,
    height: 48,
    justifyContent: "center",
    alignItems: "center",
    marginTop: 24,
  },
  img: {
    width: "100%",
    height: "100%",
  },
});
