循环内的Firebase实时数据库侦听器工作不正常

const firebase = require('firebase/app');
require('firebase/database');

// 初始化Firebase
const firebaseConfig = {
    // ...你的配置
};
firebase.initializeApp(firebaseConfig);
const database = firebase.database();

function setupAndRemoveListeners(paths) {
    paths.forEach(path => {
        const listener = database.ref(path).on('value', snapshot => {
            console.log(`Data at ${path} changed:`, snapshot.val());
        });

        // 假设我们在某个条件下移除侦听器
        setTimeout(() => {
            database.ref(path).off('value', listener);
            console.log(`Listener at ${path} removed.`);
        }, 5000); // 5秒后移除
    });
}

// 假设我们有一组路径
const pathsToWatch = ['/path1', '/path2', '/path3'];
setupAndRemoveListeners(pathsToWatch);
