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

• 用户管理

• 预约挂号

• 在线问诊

• 电子病历

• 药品管理

• 支付结算
  

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：

• 用户服务

• 预约服务

• 问诊服务

• 病历服务

• 药品服务

• 支付服务

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：

• 后端：Java（Spring Boot）、Python（Django/Flask）

• 前端：React.js、Vue.js

• 数据库：MySQL、MongoDB

• 消息队列：RabbitMQ、Kafka

• 视频服务：WebRTC

• 支付：支付宝、微信支付

• 云服务：AWS、阿里云

三、系统开发

3.1 后端开发

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-web</artifactId>

</dependency>

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-data-jpa</artifactId>

</dependency>

<dependency>

    <groupId>mysql</groupId>

    <artifactId>mysql-connector-java</artifactId>

</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 (

        <div>

            <h2>Register</h2>

            <input type="text" value={username} onChange={(e) => setUsername(e.target.value)} placeholder="Username" />

            <input type="password" value={password} onChange={(e) => setPassword(e.target.value)} placeholder="Password" />

            <button onClick={handleRegister}>Register</button>

        </div>

    );

}

 

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 (

        <div>

            <video ref={localVideoRef} autoPlay muted></video>

            <video ref={remoteVideoRef} autoPlay></video>

        </div>

    );

}

 

export default VideoChat;
