搭建智慧互联网医院系统教学：源码解析与在线问诊APP开发

本篇文章，小编将以“源码解析与在线问诊APP开发”为切入点，详细介绍搭建智慧互联网医院系统的过程。

互联网医院系统源码

一、智慧互联网医院系统的架构设计

系统架构概述

-前端

-后端

-数据库

功能模块划分

-用户

-预约

-挂号

-问诊、

-病历

-管理

-药品

-配送

……

二、源码解析

以简单的在线问诊模块为例，进行源码解析。

数据库设计

首先，设计数据库表结构。在线问诊模块涉及的主要表有用户表（User）、医生表（Doctor）、问诊记录表（Consultation）。


-- 用户表CREATE TABLE User (id INT PRIMARY KEY AUTO_INCREMENT,username VARCHAR(50) NOT NULL,password VARCHAR(50) NOT NULL,role ENUM('patient', 'doctor') NOT NULL);-- 医生表CREATE TABLE Doctor (id INT PRIMARY KEY AUTO_INCREMENT,user_id INT,specialty VARCHAR(100),FOREIGN KEY (user_id) REFERENCES User(id));-- 问诊记录表CREATE TABLE Consultation (id INT PRIMARY KEY AUTO_INCREMENT,patient_id INT,doctor_id INT,consultation_time DATETIME,description TEXT,FOREIGN KEY (patient_id) REFERENCES User(id),FOREIGN KEY (doctor_id) REFERENCES Doctor(id));

后端实现

后端使用Node.js和Express框架进行开发。


const express = require('express');const app = express();const bodyParser = require('body-parser');const mysql = require('mysql');app.use(bodyParser.json());const db = mysql.createConnection({host: 'localhost',user: 'root',password: 'password',database: 'smart_hospital'});db.connect((err) => {if (err) throw err;console.log('Database connected!');});// 用户注册接口app.post('/register', (req, res) => {let user = req.body;let sql = 'INSERT INTO User (username, password, role) VALUES (?, ?, ?)';db.query(sql, [user.username, user.password, user.role], (err, result) => {if (err) throw err;res.send('User registered!');});});// 在线问诊接口app.post('/consult', (req, res) => {let consult = req.body;let sql = 'INSERT INTO Consultation (patient_id, doctor_id, consultation_time, description) VALUES (?, ?, ?, ?)';db.query(sql, [consult.patient_id, consult.doctor_id, consult.consultation_time, consult.description], (err, result) => {if (err) throw err;res.send('Consultation record created!');});});app.listen(3000, () => {console.log('Server started on port 3000');});

前端实现

前端使用React框架。


import React, { useState } from 'react';import axios from 'axios';function App() {const [username, setUsername] = useState('');const [password, setPassword] = useState('');const [role, setRole] = useState('patient');const [description, setDescription] = useState('');const register = () => {axios.post('/register', { username, password, role }).then(response => {alert(response.data);});};const consult = () => {axios.post('/consult', { patient_id: 1, doctor_id: 1, consultation_time: new Date(), description }).then(response => {alert(response.data);});};return (<div><h1>智慧互联网医院</h1><div><h2>用户注册</h2><input type="text" value={username} onChange={e => setUsername(e.target.value)} placeholder="用户名" /><input type="password" value={password} onChange={e => setPassword(e.target.value)} placeholder="密码" /><select value={role} onChange={e => setRole(e.target.value)}><option value="patient">患者</option><option value="doctor">医生</option></select><button onClick={register}>注册</button></div><div><h2>在线问诊</h2><textarea value={description} onChange={e => setDescription(e.target.value)} placeholder="描述病情"></textarea><button onClick={consult}>提交问诊</button></div></div>);}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。

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：


npx react-native init SmartHospitalAppcd SmartHospitalAppnpx react-native run-android   或 npx react-native run-ios

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。


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 [description, setDescription] = 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(), description }).then(response => {Alert.alert(response.data);});};return (<View style={{ padding: 20 }}><Text style={{ fontSize: 24 }}>智慧互联网医院</Text><View style={{ marginVertical: 20 }}><Text style={{ fontSize: 18 }}>用户注册</Text><TextInput value={username} onChangeText={setUsername} placeholder="用户名" /><TextInput value={password} onChangeText={setPassword} placeholder="密码" secureTextEntry /><TextInput value={role} onChangeText={setRole} placeholder="角色（patient或doctor）" /><Button title="注册" onPress={register} /></View><View style={{ marginVertical: 20 }}><Text style={{ fontSize: 18 }}>在线问诊</Text><TextInput value={description} onChangeText={setDescription} placeholder="描述病情" multiline /><Button title="提交问诊" onPress={consult} /></View></View>);};export default App;
