如何同时从Firebase和setState中拉取多个数据

import React, { Component } from 'react';
import firebase from 'firebase';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      firebaseData: [],
      otherData: [],
      combinedData: []
    };
  }

  componentDidMount() {
    // 从Firebase获取数据
    const firebaseRef = firebase.database().ref('path/to/firebaseData');
    firebaseRef.on('value', snapshot => {
      const firebaseData = snapshot.val();
      this.setState({ firebaseData }, () => {
        this.combineData();
      });
    });

    // 从其他数据源获取数据
    // ...

    // 使用Promise.all()等待所有异步请求完成
    Promise.all([firebaseRef, otherDataPromise])
      .then(([firebaseData, otherData]) => {
        this.setState({ firebaseData, otherData }, () => {
          this.combineData();
        });
      })
      .catch(error => {
        console.log(error);
      });
  }

  combineData() {
    // 合并数据并存储在组件状态中
    const { firebaseData, otherData } = this.state;
    const combinedData = [...firebaseData, ...otherData];
    this.setState({ combinedData });
  }

  render() {
    // 渲染组件
    // ...
  }
}

export default MyComponent;
