1. 智能代码生成与补全

基础生成

javascript

// 使用Cmd+K (Mac) 或 Ctrl+K (Win) 打开AI指令面板
// 输入：创建一个React表单组件，包含邮箱和密码验证

// Cursor自动生成完整组件
import React, { useState } from 'react';
import { Mail, Lock, Eye, EyeOff } from 'lucide-react';

const AuthForm = ({ onSubmit, loading = false }) => {
  const [formData, setFormData] = useState({
    email: '',
    password: ''
  });
  const [errors, setErrors] = useState({});
  const [showPassword, setShowPassword] = useState(false);

  const validateEmail = (email) => {
    const regex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
    return regex.test(email);
  };

  const validateForm = () => {
    const newErrors = {};
    
    if (!formData.email.trim()) {
      newErrors.email = '邮箱不能为空';
    } else if (!validateEmail(formData.email)) {
      newErrors.email = '请输入有效的邮箱地址';
    }
    
    if (!formData.password) {
      newErrors.password = '密码不能为空';
    } else if (formData.password.length < 6) {
      newErrors.password = '密码至少6位字符';
    }
    
    setErrors(newErrors);
    return Object.keys(newErrors).length === 0;
  };

  const handleSubmit = (e) => {
    e.preventDefault();
    if (validateForm()) {

        <input
          type="email"
          name="email"
          value={formData.email}
          onChange={handleChange}
          className={`w-full px-4 py-3 border rounded-lg focus:ring-2 focus:ring-blue-500 focus:border-transparent ${
            errors.email ? 'border-red-500' : 'border-gray-300'

      >
        {loading ? '提交中...' : '登录'}
      </button>
    </form>
  );
};

export default AuthForm;

上下文感知生成

javascript

// Cursor能理解项目中的现有组件并生成匹配的代码
// 在项目中已有Button组件的情况下，Cursor会生成一致的API

// 输入：创建一个Modal组件，使用我们的Button组件作为关闭按钮
import React from 'react';
import Button from '../Button'; // Cursor自动识别项目中的Button路径
import { X } from 'lucide-react';

const Modal = ({ isOpen, onClose, title, children, size = 'md' }) => {
  if (!isOpen) return null;

  const sizeClasses = {
    sm: 'max-w-md',
    md: 'max-w-lg',
    lg: 'max-w-2xl',
    xl: 'max-w-4xl'
  };

  return (
    <div className="fixed inset-0 z-50 overflow-y-auto">
      <div className="flex items-center justify-center min-h-screen px-4 pt-4 pb-20 text-center sm:block sm:p-0">
        {/* 背景遮罩 */}
        <div 
          className="fixed inset-0 transition-opacity bg-gray-500 bg-opacity-75"
          onClick={onClose}
        />

        {/* Modal容器 */}
        <div className={`inline-block align-bottom bg-white rounded-lg text-left overflow-hidden shadow-xl transform transition-all sm:my-8 sm:align-middle sm:w-full ${sizeClasses[size]}`}>
          {/* Header */}
          <div className="px-6 py-4 border-b border-gray-200">
            <div className="flex items-center justify-between">
              <h3 className="text-lg font-medium text-gray-900">{title}</h3>
              <Button
                variant="ghost"
                size="sm"
                onClick={onClose}
                className="p-1 hover:bg-gray-100 rounded-full"
              >
                <X size={20} />
              </Button>
            </div>
          </div>

          {/* Content */}
          <div className="px-6 py-4">

            <div className="flex justify-end space-x-3">
              <Button variant="outline" onClick={onClose}>
                取消
              </Button>
              <Button>
                确认
              </Button>
            </div>
          </div>
        </div>
      </div>
    </div>
  );
};

export default Modal;

2. 智能重构与优化

javascript

// 重构前：冗长的组件
function UserProfile({ user }) {
  return (
    <div>
      {user ? (
        <div>
          <img src={user.avatar} alt={user.name} />
          <h2>{user.name}</h2>
          <p>{user.bio}</p>
          <div>
            {user.skills.map(skill => (
              <span key={skill}>{skill}</span>
            ))}
          </div>
        </div>
      ) : (
        <p>加载中...</p>
      )}
    </div>
  );
}

// 使用Cursor重构（选中代码，Cmd/Ctrl+L，输入"重构这个组件"）
// Cursor重构后：
import React from 'react';
import { User, Briefcase, MapPin } from 'lucide-react';

const UserProfile = ({ user, loading = false }) => {
  if (loading) {
    return (
      <div className="animate-pulse space-y-4">
        <div className="h-48 bg-gray-200 rounded-lg" />
        <div className="h-4 bg-gray-200 rounded w-3/4" />
        <div className="h-4 bg-gray-200 rounded w-1/2" />
      </div>
    );
  }

  if (!user) {
    return (
      <div className="text-center py-12">
        <User size={48} className="mx-auto text-gray-400 mb-4" />
        <p className="text-gray-500">用户不存在</p>
      </div>
    );
  }

  return (
    <div className="bg-white rounded-xl shadow-lg overflow-hidden">
      {/* Header */}
      <div className="relative h-48 bg-gradient-to-r from-blue-500 to-purple-600">
        <div className="absolute -bottom-12 left-6">
          <img
            src={user.avatar}
            alt={user.name}
            className="w-24 h-24 rounded-full border-4 border-white object-cover"
          />
        </div>
      </div>

      {/* Content */}
      <div className="pt-16 px-6 pb-6">
        <div className="flex items-start justify-between mb-4">
          <div>
            <h1 className="text-2xl font-bold text-gray-900">{user.name}</h1>
            <p className="text-gray-600">{user.title}</p>
          </div>
          <span className="px-3 py-1 bg-blue-100 text-blue-800 text-sm font-medium rounded-full">
            {user.role}
          </span>
        </div>

        {/* Details */}
        <div className="grid grid-cols-1 md:grid-cols-2 gap-4 mb-6">
          <div className="flex items-center gap-2 text-gray-600">

            <span>{user.company}</span>
          </div>
          <div className="flex items-center gap-2 text-gray-600">
            <MapPin size={18} />
            <span>{user.location}</span>
          </div>
        </div>

        {/* Skills */}
        <div>
          <h3 className="font-medium text-gray-900 mb-3">技能</h3>
          <div className="flex flex-wrap gap-2">
            {user.skills.map((skill) => (
              <span
                key={skill}
                className="px-3 py-1 bg-gray-100 text-gray-800 text-sm rounded-full hover:bg-gray-200 transition-colors"
              >
                {skill}
              </span>
            ))}
          </div>
        </div>
      </div>
    </div>
  );
};

export default UserProfile;

3. 智能调试与问题解决

javascript

// 遇到Bug时，只需将错误信息告诉Cursor
// 输入：这个useEffect有无限循环问题，如何修复？

// 问题代码：
function ProductList({ category }) {
  const [products, setProducts] = useState([]);
  const [loading, setLoading] = useState(false);

  useEffect(() => {
    fetchProducts();
  }, [category]); // 依赖项问题

  const fetchProducts = async () => {
    setLoading(true);
    try {
      const response = await fetch(`/api/products?category=${category}`);
      const data = await response.json();
      setProducts(data);
    } catch (error) {
      console.error('Failed to fetch products:', error);
    } finally {
      setLoading(false);
    }
  };

  // ... 渲染逻辑
}

// Cursor分析：
// 1. fetchProducts函数在每次渲染时都会重新创建
// 2. 导致useEffect依赖项每次都在变化
// 3. 解决方案：使用useCallback或直接内联函数

// Cursor修复方案：
function ProductList({ category }) {
  const [products, setProducts] = useState([]);
  const [loading, setLoading] = useState(false);

  useEffect(() => {
    const fetchProducts = async () => {
      setLoading(true);
      try {
        const response = await fetch(`/api/products?category=${category}`);
        const data = await response.json();
        setProducts(data);
      } catch (error) {
        console.error('Failed to fetch products:', error);
      } finally {
        setLoading(false);
      }
    };

    fetchProducts();
  }, [category]); // 现在依赖项稳定了

  // 或者使用useCallback
  const fetchProducts = useCallback(async () => {
    setLoading(true);
    try {
      const response = await fetch(`/api/products?category=${category}`);
      const data = await response.json();
      setProducts(data);
    } catch (error) {
      console.error('Failed to fetch products:', error);
    } finally {
      setLoading(false);
    }
  }, [category]);

  useEffect(() => {
    fetchProducts();
  }, [fetchProducts]);
}

4. 测试代码生成

javascript

// 输入：为这个UserService生成Jest测试用例
class UserService {
  constructor(apiClient) {
    this.apiClient = apiClient;
  }

  async getUser(id) {
    const response = await this.apiClient.get(`/users/${id}`);
    return response.data;
  }

  async updateUser(id, data) {
    const response = await this.apiClient.put(`/users/${id}`, data);
    return response.data;
  }

  async deleteUser(id) {
    await this.apiClient.delete(`/users/${id}`);
    return true;
  }
}

// Cursor生成的测试代码：
import UserService from './UserService';

describe('UserService', () => {
  let userService;
  let mockApiClient;

  beforeEach(() => {
    mockApiClient = {
      get: jest.fn(),
      put: jest.fn(),
      delete: jest.fn()
    };
    userService = new UserService(mockApiClient);
  });

  describe('getUser', () => {
    it('应该正确调用API并返回用户数据', async () => {
      const mockUser = { id: 1, name: '张三', email: 'zhangsan@example.com' };
      mockApiClient.get.mockResolvedValue({ data: mockUser });

      const result = await userService.getUser(1);

      expect(mockApiClient.get).toHaveBeenCalledWith('/users/1');
      expect(result).toEqual(mockUser);
    });

    it('API调用失败时应该抛出错误', async () => {
      const error = new Error('Network error');
      mockApiClient.get.mockRejectedValue(error);

      await expect(userService.getUser(1)).rejects.toThrow('Network error');
    });
  });

  describe('updateUser', () => {
    it('应该正确更新用户数据', async () => {
      const updateData = { name: '李四', email: 'lisi@example.com' };
      const mockResponse = { id: 1, ...updateData };
      mockApiClient.put.mockResolvedValue({ data: mockResponse });

      const result = await userService.updateUser(1, updateData);

      expect(mockApiClient.put).toHaveBeenCalledWith('/users/1', updateData);
      expect(result).toEqual(mockResponse);
    });

    it('无效数据应该抛出验证错误', async () => {
      const invalidData = { email: 'invalid-email' };
      const error = new Error('Validation failed');
      mockApiClient.put.mockRejectedValue(error);

      await expect(userService.updateUser(1, invalidData)).rejects.toThrow('Validation failed');
    });
  });

  describe('deleteUser', () => {
    it('应该成功删除用户', async () => {
      mockApiClient.delete.mockResolvedValue({});

      const result = await userService.deleteUser(1);

      expect(mockApiClient.delete).toHaveBeenCalledWith('/users/1');
      expect(result).toBe(true);
    });

    it('删除不存在用户应该抛出错误', async () => {
      mockApiClient.delete.mockRejectedValue(new Error('User not found'));

      await expect(userService.deleteUser(999)).rejects.toThrow('User not found');
    });
  });
});

React组件库开发

javascript

// 输入：创建一个可复用的Button组件系统，支持多种变体、尺寸、图标

// Cursor生成的组件系统：
import React, { forwardRef } from 'react';
import { Loader2, LucideIcon } from 'lucide-react';
import { cva, type VariantProps } from 'class-variance-authority';
import { cn } from '@/lib/utils';

const buttonVariants = cva(
  'inline-flex items-center justify-center whitespace-nowrap rounded-md text-sm font-medium ring-offset-background transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:pointer-events-none disabled:opacity-50',
  {
    variants: {
      variant: {
        default: 'bg-primary text-primary-foreground hover:bg-primary/90',
        destructive: 'bg-destructive text-destructive-foreground hover:bg-destructive/90',
        outline: 'border border-input bg-background hover:bg-accent hover:text-accent-foreground',
        secondary: 'bg-secondary text-secondary-foreground hover:bg-secondary/80',
        ghost: 'hover:bg-accent hover:text-accent-foreground',
        link: 'text-primary underline-offset-4 hover:underline'
      },
      size: {
        default: 'h-10 px-4 py-2',
        sm: 'h-9 rounded-md px-3',
        lg: 'h-11 rounded-md px-8',
        icon: 'h-10 w-10'
      }
    },
    defaultVariants: {
      variant: 'default',
      size: 'default'
    }
  }
);

export interface ButtonProps
  extends React.ButtonHTMLAttributes<HTMLButtonElement>,
    VariantProps<typeof buttonVariants> {
  loading?: boolean;
  icon?: LucideIcon;
  iconPosition?: 'left' | 'right';
}

const Button = forwardRef<HTMLButtonElement, ButtonProps>(
  ({ 
    className, 
    variant, 
    size, 
    loading = false, 
    icon: Icon, 
    iconPosition = 'left', 
    children, 
    disabled, 
    ...props 
  }, ref) => {
    const isDisabled = disabled || loading;
    
    return (
      <button
        className={cn(buttonVariants({ variant, size, className }))}
        ref={ref}
        disabled={isDisabled}
        {...props}
      >
        {loading && (
          <Loader2 className={cn(
            "h-4 w-4 animate-spin",
            children ? (iconPosition === 'left' ? 'mr-2' : 'ml-2') : ''
          )} />
        )}
        
        {!loading && Icon && iconPosition === 'left' && (
          <Icon className="mr-2 h-4 w-4" />
        )}
        
        {children}
        
        {!loading && Icon && iconPosition === 'right' && (
          <Icon className="ml-2 h-4 w-4" />
        )}
      </button>
    );
  }
);

Button.displayName = 'Button';

export { Button, buttonVariants };

第五部分：性能优化与最佳实践

1. 提升AI响应质量

javascript

// 提供充分的上下文信息
// ✅ 好的提问：
// 在现有UserContext基础上，添加一个购物车功能，需要同步到后端

// ❌ 不好的提问：
// 加个购物车功能

// 提供代码示例期望格式
const example = {
  // 展示期望的数据结构
  user: { id: 1, name: '张三' },
  cart: { items: [], total: 0 }
};

2. 减少Token使用

javascript

// 使用文件引用而非粘贴代码
// ✅ 好的方式：
@file ./src/components/UserCard.jsx
在这个组件基础上，添加一个编辑模式

// ❌ 不好的方式：
// 粘贴整个文件代码...

3. 批量处理任务

bash

# 使用命令行工具批量生成
cursor generate --pattern "src/components/**/*.jsx" --template component
cursor test --coverage --update
cursor lint --fix --quiet

第六部分：故障排除与进阶技巧

常见问题解决

问题	解决方案
AI响应慢	切换模型到GPT-3.5，减少上下文长度
代码补全不工作	检查网络，重新启动Cursor
上下文丢失	确保相关文件已保存，使用@file指令
内存占用高	禁用不必要的扩展，清除缓存

调试模式

bash

# 启用详细日志
cursor --verbose --log-level=debug

# 清除缓存
cursor --clear-cache

# 重置设置
cursor --reset-settings
