java/php/node.js/python养老系统小程序【2024年毕设】

本示例提供了一个简化版的养老系统小程序的代码框架。具体的代码实现会根据你的具体需求和数据库设计进行调整。

Java 版本的后端代码示例：

// 导入Spring框架相关的包
import org.springframework.web.bind.annotation.*;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.List;
 
@RestController
@RequestMapping("/api/elderly")
public class ElderlyController {
 
    @Autowired
    private ElderlyService elderlyService;
 
    // 获取所有老人信息
    @GetMapping
    public List<Elderly> getAllElderly() {
        return elderlyService.findAll();
    }
 
    // 根据ID获取单个老人信息
    @GetMapping("/{id}")
    public Elderly getElderlyById(@PathVariable(value = "id") Long elderlyId) {
        return elderlyService.findById(elderlyId);
    }
 
    // 添加老人信息
    @PostMapping
    public Elderly addElderly(@RequestBody Elderly elderly) {
        return elderlyService.save(elderly);
    }
 
    // 更新老人信息
    @PutMapping("/{id}")
    public Elderly updateElderly(@PathVariable(value = "id") Long elderlyId, @RequestBody Elderly elderlyDetails) {
        return elderlyService.update(elderlyId, elderlyDetails);
    }
 
    // 删除老人信息
    @DeleteMapping("/{id}")
    public String deleteElderly(@PathVariable(value = "id") Long elderlyId) {
        elderlyService.deleteById(elderlyId);
        return "Elderly deleted successfully";
    }
}

在这个示例中，我们定义了一个ElderlyController类，它包含了对老人信息的基本CURD操作。这些操作通过HTTP请求进行，并且返回JSON格式的响应。

Python 版本的后端代码示例：

from flask import Flask, jsonify, request
 
app = Flask(__name__)
elderly_data = []
 
@app.route('/elderly', methods=['GET'])
def get_all_elderly():
    return jsonify(elderly_data)
 
@app.route('/elderly/<int:id>', methods=['GET'])
def get_elderly_by_id(id):
    return jsonify(elderly_data[id])
 
@app.route('/elderly', methods=['POST'])
def add_elderly():
    elderly = request.json
    elderly_data.append(elderly)
    return jsonify(elderly), 201
 
@app.route('/elderly/<int:id>', methods=['PUT'])
def update_elderly(id):
    if id >= len(elderly_data):
        return "Elderly not found", 404
    elderly = request.json
    elderly_data[id] = elderly
    return jsonify(elderly)
 
@app.route('/elderly/<int:id>', methods=['DELETE'])
def delete_elderly(id):
    if id >= len(elderly_data):
        return "Elderly not found", 404
    elderly_data.pop(id)
    return "Elderly deleted successfully", 204
 
if __name__ == '__main__':
    app.run(debug=True)
