尝试将信息从mysql数据库传递到react native

const express = require('express');
const mysql = require('mysql2');

const app = express();

// 创建数据库连接
const connection = mysql.createConnection({
  host: 'localhost',
  user: 'your_username',
  password: 'your_password',
  database: 'your_database',
});

// 查询数据库中的数据
app.get('/api/data', (req, res) => {
  connection.query('SELECT * FROM your_table', (error, results) => {
    if (error) {
      throw error;
    }
    res.json(results);
  });
});

// 启动服务器
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

import React, { useEffect, useState } from 'react';
import { View, Text } from 'react-native';
import axios from 'axios';

const App = () => {
  const [data, setData] = useState([]);

  useEffect(() => {
    // 发送HTTP请求获取数据
    axios.get('http://localhost:3000/api/data')
      .then(response => {
        setData(response.data);
      })
      .catch(error => {
        console.error(error);
      });
  }, []);

  return (
    <View>
      {data.map(item => (
        <Text key={item.id}>{item.name}</Text>
      ))}
    </View>
  );
};

export default App;
