    // Cursor AI会自动补全useEffect依赖项
    console.log('Component mounted');
    return () => {
      console.log('Component will unmount');
    };
  }, []);

  return (
    <Card className="w-full max-w-2xl mx-auto my-4">
      <CardHeader>
        <CardTitle>Cursor AI 代码补全示例</CardTitle>
      </CardHeader>
      <CardContent>
        <div className="space-y-4">
          <div className="p-4 bg-gray-100 rounded-md">
            <h3 className="font-semibold mb-2">函数补全示例</h3>
            <input 
              type="text"
              className="w-full p-2 border rounded"
              onChange={handleUserInput}
              placeholder="输入以触发自动补全"
            />

      </CardContent>
    </Card>
  );
};

export default CodeCompletionDemo;

3. 自然语言编程流程图

二、实用代码示例与最佳实践

1. 错误处理最佳实践

# 示例：统一的错误处理模式
class CustomError(Exception):
    """自定义错误基类"""
    def __init__(self, message, error_code=None):
        self.message = message
        self.error_code = error_code
        super().__init__(self.message)

def safe_operation(func):
    """错误处理装饰器"""
    def wrapper(*args, **kwargs):
        try:
            return func(*args, **kwargs)
        except CustomError as e:
            print(f"已知错误: {e.message} (错误代码: {e.error_code})")
            return None
        except Exception as e:
            print(f"未知错误: {str(e)}")
            return None
    return wrapper

@safe_operation
def process_data(data):
    if not data:
        raise CustomError("数据不能为空", "E001")
    # 处理数据的代码
    return data

# 使用示例
result = process_data([])  # 输出: 已知错误: 数据不能为空 (错误代码: E001)

2. 模块化设计示例

# data_handler.py
class DataHandler:
    def __init__(self):
        self.data = []
    
    def add_data(self, item):
        if self.validate_data(item):
            self.data.append(item)
            return True
        return False
    
    def validate_data(self, item):
        return isinstance(item, dict) and 'id' in item
    
    def get_data(self):
        return self.data

# api_service.py
class APIService:
    def __init__(self, data_handler):
        self.data_handler = data_handler
    
    def process_request(self, request_data):
        if self.data_handler.add_data(request_data):
            return {"status": "success", "message": "数据添加成功"}
        return {"status": "error", "message": "数据格式无效"}

# main.py
def main():
    data_handler = DataHandler()
    api_service = APIService(data_handler)
    
    # 测试数据
    test_data = {"id": 1, "name": "测试项目"}
    result = api_service.process_request(test_data)
    print(result)  # 输出: {'status': 'success', 'message': '数据添加成功'}

if __name__ == "__main__":
    main()

3. 代码复用策略

import React from 'react';
import { Card, CardHeader, CardTitle, CardContent } from '@/components/ui/card';

// 可复用的表单输入组件
const FormInput = ({ label, value, onChange, type = 'text' }) => (
  <div className="mb-4">
    <label className="block text-gray-700 text-sm font-bold mb-2">
      {label}
    </label>
    <input
      type={type}
      value={value}
      onChange={onChange}
      className="shadow appearance-none border rounded w-full py-2 px-3 text-gray-700"
    />
  </div>
);

// 可复用的按钮组件
const Button = ({ onClick, children, variant = 'primary' }) => {
  const baseClasses = "font-bold py-2 px-4 rounded";
  const variantClasses = {
    primary: "bg-blue-500 hover:bg-blue-700 text-white",
    secondary: "bg-gray-500 hover:bg-gray-700 text-white",
    danger: "bg-red-500 hover:bg-red-700 text-white"
  };

  return (
    <button
      onClick={onClick}
      className={`${baseClasses} ${variantClasses[variant]}`}
    >
      {children}
    </button>
  );
};

// 使用可复用组件的表单
const UserForm = () => {
  const [userData, setUserData] = React.useState({
    username: '',
    email: ''
  });

  const handleSubmit = () => {
    console.log('Form submitted:', userData);
  };

  return (
    <Card className="w-full max-w-lg mx-auto">
      <CardHeader>
        <CardTitle>用户信息表单</CardTitle>
      </CardHeader>
      <CardContent>
        <FormInput
          label="用户名"
          value={userData.username}
          onChange={(e) => setUserData({...userData, username: e.target.value})}
        />
        <FormInput
          label="邮箱"
          type="email"
          value={userData.email}
          onChange={(e) => setUserData({...userData, email: e.target.value})}
        />
        <div className="space-x-4">
          <Button onClick={handleSubmit}>提交</Button>
          <Button variant="secondary" onClick={() => setUserData({ username: '', email: '' })}>
            重置
          </Button>
        </div>
      </CardContent>
    </Card>
  );
};

export default UserForm;

三、Cursor AI与开发工具集成最佳实践

1. 版本控制集成

# Git集成最佳实践
# 1. 初始化项目
git init
cursor .  # 使用Cursor打开项目

# 2. 创建.gitignore文件
echo "node_modules/" >> .gitignore
echo ".cursor/" >> .gitignore  # 忽略Cursor配置文件

# 3. 配置Git钩子以在提交前运行代码检查
cat > .git/hooks/pre-commit << EOL
#!/bin/bash
cursor --lint  # 运行Cursor内置的代码检查
if [ $? -eq 0 ]; then
    echo "代码检查通过"
    exit 0
else
    echo "代码检查失败"
    exit 1
fi
EOL
chmod +x .git/hooks/pre-commit

2. 调试技巧流程图

3. 项目管理工具集成示例

// 创建一个简单的任务跟踪系统
const TaskTracker = {
    tasks: [],
    
    addTask(description) {
        const task = {
            id: Date.now(),
            description,
            status: 'pending',
            created: new Date(),
            updated: new Date()
        };
        this.tasks.push(task);
        this.syncWithCursor(task);
        return task;
    },
    
    updateTask(id, updates) {
        const task = this.tasks.find(t => t.id === id);
        if (task) {
            Object.assign(task, updates, { updated: new Date() });
            this.syncWithCursor(task);
            return task;
        }
        return null;
    },
    
    syncWithCursor(task) {
        // 与Cursor AI集成，自动生成相关代码注释
        const comment = `// Task ${task.id}: ${task.description}\n// Status: ${task.status}\n`;
        // 使用Cursor API添加注释（示例代码）
        console.log(`Synced task with Cursor: ${comment}`);
    }
};

// 使用示例
const task = TaskTracker.addTask("实现用户认证功能");
TaskTracker.updateTask(task.id, { status: 'in-progress' });

四、性能优化最佳实践

1. 代码性能优化示例

// 性能优化示例

// 1. 使用缓存优化计算密集型操作
const memoize = (fn) => {
    const cache = new Map();
    return (...args) => {
        const key = JSON.stringify(args);
        if (cache.has(key)) {
            console.log('从缓存获取结果');
            return cache.get(key);
        }
        const result = fn.apply(this, args);
        cache.set(key, result);
        return result;
    };
};

// 示例：计算斐波那契数列
const fibonacci = (n) => {
    if (n < 2) return n;
    return fibonacci(n - 1) + fibonacci(n - 2);
};

const memoizedFibonacci = memoize(fibonacci);

// 2. 批量处理优化
class BatchProcessor {
    constructor(batchSize = 1000) {
        this.batchSize = batchSize;
        this.queue = [];
        this.processing = false;
    }

    async add(item) {
        this.queue.push(item);
        if (this.queue.length >= this.batchSize && !this.processing) {
            await this.process();
        }
    }

    async process() {
        if (this.processing || this.queue.length === 0) return;
        
        this.processing = true;
        const batch = this.queue.splice(0, this.batchSize);
        
        try {
            console.log(`Processing batch of ${batch.length} items`);
            // 在这里处理批量数据
            await Promise.all(batch.map(item => this.processItem(item)));
        } catch (error) {
            console.error('Batch processing error:', error);
        } finally {
            this.processing = false;
            if (this.queue.length >= this.batchSize) {
                await this.process();
            }
        }
    }

    async processItem(item) {
        // 模拟处理单个项目
        return new Promise(resolve => setTimeout(() => resolve(item), 100));
    }
}

// 3. 异步操作优化
class AsyncOperationManager {
    constructor() {
        this.pendingOperations = new Map();
    }

    async executeAsync(key, operation) {
        if (this.pendingOperations.has(key)) {
            console.log(`复用已存在的操作: ${key}`);
            return this.pendingOperations.get(key);
        }

        const promise = operation().finally(() => {
            this.pendingOperations.delete(key);
        });

        this.pendingOperations.set(key, promise);
        return promise;
    }
}

// 使用示例
async function performanceTest() {
    // 测试缓存优化
    console.time('未缓存的斐波那契');
    fibonacci(40);
    console.timeEnd('未缓存的斐波那契');

    console.time('缓存的斐波那契');
    memoizedFibonacci(40);
    console.timeEnd('缓存的斐波那契');

    // 测试批量处理
    const batchProcessor = new BatchProcessor(5);
    for (let i = 0; i < 20; i++) {
        await batchProcessor.add(`item-${i}`);
    }

    // 测试异步操作管理
    const asyncManager = new AsyncOperationManager();
    const operation = () => new Promise(resolve => 
        setTimeout(() => resolve('操作完成'), 1000)
    );

    const results = await Promise.all([
        asyncManager.executeAsync('test', operation),
        asyncManager.executeAsync('test', operation) // 这个会复用第一个操作
    ]);

    console.log('异步操作结果:', results);
}

performanceTest().catch(console.error);

2. 性能优化策略图

3. 集成测试最佳实践

import unittest
from unittest.mock import patch
import requests

class APITestCase(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        """测试类初始化"""
        cls.base_url = 'http://api.example.com'
        cls.test_user = {
            'username': 'test_user',
            'email': 'test@example.com'
        }

    def setUp(self):
        """每个测试用例前的初始化"""
        self.session = requests.Session()
        self.session.headers.update({
            'Content-Type': 'application/json',
            'Accept': 'application/json'
        })

    @patch('requests.Session.post')
    def test_user_creation(self, mock_post):
        """测试用户创建功能"""
        # 模拟API响应
        mock_post.return_value.status_code = 201
        mock_post.return_value.json.return_value = {
            'id': 1,
            **self.test_user
        }

        # 发送请求
        response = self.session.post(
            f'{self.base_url}/users',
            json=self.test_user
        )

        # 断言
        self.assertEqual(response.status_code, 201)
        self.assertEqual(response.json()['username'], self.test_user['username'])

    @patch('requests.Session.get')
    def test_user_retrieval(self, mock_get):
        """测试用户信息获取功能"""
        user_id = 1
        mock_get.return_value.status_code = 200
        mock_get.return_value.json.return_value = {
            'id': user_id,
            **self.test_user
        }

        # 发送请求
        response = self.session.get(f'{self.base_url}/users/{user_id}')

        # 断言
        self.assertEqual(response.status_code, 200)
        self.assertEqual(response.json()['id'], user_id)

    def tearDown(self):
        """每个测试用例后的清理"""
        self.session.close()

if __name__ == '__main__':
    unittest.main()
