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)
