);
}
export default App;
```
三、在线问诊APP开发
在移动互联网时代,开发一款便捷的在线问诊APP是智慧互联网医院系统的重要组成部分。我们可以使用React Native框架来开发跨平台移动应用。
1. 环境搭建
首先,搭建React Native开发环境。安装Node.js后,使用以下命令创建React Native项目:
```bash
npx react-native init SmartHospitalApp
cd SmartHospitalApp
npx react-native run-android 或 npx react-native run-ios
```
2. 开发APP功能
我们将主要实现用户注册和在线问诊功能,与前端网页类似。
```javascri-pt
import React, { useState } from ’react’;
import { View, TextInput, Button, Text, Alert } from ’react-native’;
import axios from ’axios’;
const App = () => {
const [username, setUsername] = useState(’’);
const [password, setPassword] = useState(’’);
const [role, setRole] = useState(’patient’);
const [descri-ption, setDescri-ption] = useState(’’);
const register = () => {
axios.post(’http://localhost:3000/register’, { username, password, role })
.then(response => {
Alert.alert(response.data);
});
};
const consult = () => {
axios.post(’http://localhost:3000/consult’, { patient_id: 1, doctor_id: 1, consultation_time: new Date(), descri-ption })
.then(response => {
Alert.alert(response.data);
});
};
