近期，互联网医院系统的热度非常高，很多人跟小编提问如何开发，今天小编将从零开始为大家详解互联网医院系统源码，以及在线问诊APP开发技术。

一、需求分析与系统设计

1.1 需求分析

1.2 系统设计

基于上述需求，我们可以将系统划分为多个模块，每个模块对应实现一部分功能。系统设计可以采用微服务架构，每个服务独立部署，彼此通过API进行通信。主要模块包括：

二、技术选型

在开发智慧互联网医院系统时，技术选型是确保系统稳定性和可扩展性的关键。以下是推荐的技术栈：

三、系统开发

3.1 后端开发

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-webartifactId>
dependency>
<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-data-jpaartifactId>
dependency>
<dependency>
    <groupId>mysqlgroupId>
    <artifactId>mysql-connector-javaartifactId>
dependency>

然后，编写用户实体类和对应的数据库表映射：

@Entity
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
 
    private String username;
    private String password;
    private String role; // PATIENT, DOCTOR, ADMIN
 
    // getters and setters
}

接着，编写用户控制器类，处理注册和登录请求：

@RestController
@RequestMapping("/api/users")
public class UserController {
    
    @Autowired
    private UserService userService;
 
    @PostMapping("/register")
    public ResponseEntity<?> register(@RequestBody User user) {
        return ResponseEntity.ok(userService.register(user));
    }
 
    @PostMapping("/login")
    public ResponseEntity<?> login(@RequestBody User user) {
        return ResponseEntity.ok(userService.login(user));
    }
}

3.2 前端开发

npx create-react-app hospital-app
cd hospital-app
npm install axios react-router-dom

编写用户注册和登录页面：

import React, { useState } from 'react';
import axios from 'axios';
 
function Register() {
    const [username, setUsername] = useState('');
    const [password, setPassword] = useState('');
 
    const handleRegister = () => {
        axios.post('/api/users/register', { username, password })
            .then(response => {
                alert('Registration successful');
            })
            .catch(error => {
                alert('Registration failed');
            });
    };
 
    return (
        

            
Register
             setUsername(e.target.value)} placeholder="Username" />
             setPassword(e.target.value)} placeholder="Password" />
            Register
        
    );
}
 
export default Register;

3.3 实现在线问诊

在线问诊是智慧互联网医院系统的核心功能之一。可以使用WebRTC技术实现实时视频问诊。

const express = require('express');
const http = require('http');
const socketIO = require('socket.io');
 
const app = express();
const server = http.createServer(app);
const io = socketIO(server);
 
io.on('connection', socket => {
    socket.on('join', room => {
        socket.join(room);
        socket.to(room).broadcast.emit('user-joined', socket.id);
    });
 
    socket.on('offer', (offer, room) => {
        socket.to(room).broadcast.emit('offer', offer);
    });
 
    socket.on('answer', (answer, room) => {
        socket.to(room).broadcast.emit('answer', answer);
    });
 
    socket.on('candidate', (candidate, room) => {
        socket.to(room).broadcast.emit('candidate', candidate);
    });
});
 
server.listen(3000, () => {
    console.log('WebRTC signaling server running on port 3000');
});

前端实现WebRTC连接：

import React, { useRef, useEffect } from 'react';
import io from 'socket.io-client';
 
const socket = io('http://localhost:3000');
 
function VideoChat() {
    const localVideoRef = useRef(null);
    const remoteVideoRef = useRef(null);
    const peerConnection = useRef(new RTCPeerConnection());
 
    useEffect(() => {
        navigator.mediaDevices.getUserMedia({ video: true, audio: true })
            .then(stream => {
                localVideoRef.current.srcObject = stream;
                stream.getTracks().forEach(track => peerConnection.current.addTrack(track, stream));
            });
 
        peerConnection.current.ontrack = (event) => {
            remoteVideoRef.current.srcObject = event.streams[0];
        };
 
        socket.on('offer', async (offer) => {
            await peerConnection.current.setRemoteDescription(new RTCSessionDescription(offer));
            const answer = await peerConnection.current.createAnswer();
            await peerConnection.current.setLocalDescription(new RTCSessionDescription(answer));
            socket.emit('answer', answer, 'room1');
        });
 
        socket.on('answer', (answer) => {
            peerConnection.current.setRemoteDescription(new RTCSessionDescription(answer));
        });
 
        socket.on('candidate', (candidate) => {
            peerConnection.current.addIceCandidate(new RTCIceCandidate(candidate));
        });
 
        peerConnection.current.onicecandidate = (event) => {
            if (event.candidate) {
                socket.emit('candidate', event.candidate, 'room1');
            }
        };
 
        socket.emit('join', 'room1');
    }, []);
 
    return (
        

            
            
        
    );
}
 
export default VideoChat;
