foxar

A 100% Flask-compatible library built on top of FastAPI, providing the best of both worlds: Flask's simplicity and FastAPI's performance.

Features

一个兼容Flask语法的FastAPI高性能库，结合了Flask的简洁语法和FastAPI的高性能特性。

特性

• Flask兼容语法：支持Flask的路由装饰器、蓝图系统和应用结构
• FastAPI高性能：底层使用FastAPI，支持异步处理和类型提示
• 自动API文档：集成Swagger UI和ReDoc，自动生成API文档
• 类型安全：支持Pydantic模型和类型提示
• 易于迁移：允许现有Flask应用轻松迁移到高性能的FastAPI

安装

pip install foxar

基本使用

from foxar import Foxar, jsonify

app = Foxar(__name__)

@app.route('/')
def index():
    return 'Hello, foxar!'

@app.route('/user/<int:user_id>')
def get_user(user_id):
    return {'user_id': user_id, 'message': f'Hello user {user_id}'}

@app.route('/login', methods=['GET', 'POST'])
def login():
    return jsonify({'status': 'success', 'message': 'Login successful'})

if __name__ == '__main__':
    app.run(debug=True, port=5000)

蓝图使用

from foxar import Foxar, Blueprint

app = Foxar(__name__)

# 创建蓝图
api_bp = Blueprint('api', __name__, url_prefix='/api')

@api_bp.route('/items')
def get_items():
    return {'items': ['item1', 'item2', 'item3']}

@api_bp.route('/items/<item_id>')
def get_item(item_id):
    return {'item_id': item_id, 'name': f'Item {item_id}'}

# 注册蓝图
app.register_blueprint(api_bp)

if __name__ == '__main__':
    app.run(debug=True, port=5000)

运行应用

使用内置run方法

app.run(debug=True, port=5000)

使用uvicorn

uvicorn your_app:app --reload --port 5000

访问API文档

• Swagger UI: http://localhost:5000/docs
• ReDoc: http://localhost:5000/redoc

主要组件

1. Foxar：主应用类，继承自FastAPI，兼容Flask的初始化和路由语法
2. Blueprint：蓝图类，封装了FastAPI的APIRouter
3. request：请求对象，兼容Flask的request接口
4. Response：响应类，兼容Flask的Response接口
5. jsonify：JSON响应工具函数
6. redirect：重定向工具函数
7. Config：配置类，兼容Flask的Config接口
8. url_for：URL生成工具函数

注意事项

• 虽然兼容Flask的基本语法，但某些Flask特有功能可能需要额外实现 (当然，你如果实现了那就是太棒了！欢迎提交PR)
• 支持异步和同步路由处理函数
• 保持了FastAPI的所有高性能特性和类型提示
• 自动生成OpenAPI文档，提供交互式API测试界面

性能优势

• 异步支持：底层使用FastAPI和Starlette，支持异步处理
• 类型提示：利用Python类型提示提高代码质量
• 自动验证：基于Pydantic的请求数据验证
• 高性能：比传统WSGI框架（如Flask）具有更高的并发处理能力

foxar为开发者提供了一种既熟悉又高效的Web框架选择，让你可以使用Flask的简洁语法，同时享受FastAPI的高性能特性。
