A web framework base on Sanic

Project description

sanic Framework boot | sanic-boot

sanic-boot

sanic-boot 基于 Sanic 框架,为开发者提供与 Spring Boot 类似的装饰器,便于路由系统、模型类的自动装配与配置。

Sanic | Build fast. Run fast.

Sanic is a Python 3.9+ web server and web framework that's written to go fast. It allows the usage of the async/await syntax added in Python 3.5, which makes your code non-blocking and speedy.

注意

本框架没有对原生的 sanic 框架造成任何侵入性的修改,但由于模型(Models)、路由(Routers)、任务(Task)等自动加载实现机制较为笨拙,可能会对 sanic 的网络请求造成不可预估的影响。

TODO List

  • 自动装配基础路由
  • 自动装配类视图路由
  • 自动装配 Background Task
  • 自动装配模型类
  • 文档
  • Websocket
  • 流式传输(Streaming)
  • 为 Controller 注入 CRUD 操作
  • 封装 APScheduler 定时任务框架

安装

# 使用 pip
pip install sanic-boot

# 使用uv
uv add sanic-boot

可能的依赖

# 使用 pip
pip install sanic sanic-ext tortoise-orm
# 或
pip install sanic[ext] tortoise-orm[asyncpg|psycopg|asyncmy|asyncodbc]

# 使用 uv
uv add ...

sanic-ext 提供 docs、cors 等; tortoise-orm 提供 ORM 等。

Hello World Example

from sanic_boot import sanicBoot
import sanic

app = sanicBoot(__name__)


# 使用 sanic 自带的装饰器仍然有效
@app.get("/")
def index(request):
    return sanic.response.text("hello")


if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8088, debug=True, auto_reload=True)

1. Create NORMAL route by common function (which can be with async)

from sanic import Request, text
from sanic_boot import GetMapping


# 面向函数
@GetMapping('/index')
async def index(request: Request):
    return text('Hello')

2. Create Router View from class, which just collect the route -- A simple method instead of blueprint

from sanic import Request, text, json
from sanic_boot import Controller, GetMapping, RequestMapping


# 面向类
@Controller('/person')
class PersonController:
    # 使用 RequestMapping 装饰器后,若发现目标是类且不是 HTTPMethodView 的子类,则会在继承链中添加 HTTPMethodView 类。
    # (*注意*:此举可能会造成多继承冲突!!!)
    @RequestMapping('/login')
    class Login:
        async def get(self, request: Request):
            return text('the route is /person/login')

    # 除视图外,还可以使用普通方法构造路由
    @GetMapping('/logout')
    async def logout(self, request: Request):
        return json({
            'code': 200,
            'data': '退出登录'
        })

3. Create Task by decorator Task, which is allowed to get a parameter named name or

taskName. If there is no parameter has, the value None will be the default value assigned to argument name

import asyncio
from sanic import Sanic
from sanic_boot import Task


@Task(name='')  # name 或 taskName 默认为 None
async def gen(app: Sanic):
    while True:
        print([item for item in range(10)])
        await asyncio.sleep(5000)

Decorator Description

  • @Controller (uri : str = '')

    装饰器 Controller 意在收集目标注解对象内部注册的路由,是 sanic 框架中 blueprint 蓝图系统的自动化实现。

    sanic 官方网站中提供了自动收集 blueprint 的辅助文件,能够帮助开发者给予蓝图系统快速构建路由系统。而装饰器 Controller 则延伸了官方方案,参考 Spring Boot 装饰器思路,提供能够相对完备的路由系统自动组装方案。

    装饰器 Controller允许不携带任何参数,此时将自动分配路由,分配的路由与目标注解的类名有关,类名推荐的格式为 ^[A-Z][A-Za-z0-9]*Controller$ ,(即大写字母开头的有意义单词,并以单词 Controller 结尾),分配所得路由为全小写且不含 Controller。如 TestController 的路由为 testTestTest2Controller 的路由为 test-test2

    注意: 若最终注册的路由存在重复将会造成路由冲突,此外,若注册的函数名在相同层级上存在重复,也会造成路由系统收集异常。故建议开发者在不同业务中为路由句柄(handler)赋予不同的名称

  • @RequestMapping(uri : str, methods: list[RequestMethod] | RequestMethod | None = None)

    使用 RequestMapping 时若注解对象是一个视图类,则第二个参数可缺省,sanic 内部的路由系统将会根据视图类的方法自动分配路由方法。装饰器 RequestMappingsanic 框架中类视图注册方法 app.add_route (Class.as_view(), ...) 的自动化实现。

  • @[Get|Post|Head|Put|Delete|Patch|Options]Mapping(uri : str)

    @GetMapping (uri : str) 等装饰器是 @RequestMapping ('/login', RequestMethod.GET) 的简便写法。需要注意的是这些简便写法尽量不要应用在视图类上。但基于实际的代码逻辑实现而言,即使对视图类上进行应用,也不会造成任何不可预计的后果。

  • @Task(name : str = None)

    在 Tasks 目录下注册任务事件。目前尚未想好如何以最佳的形式将 APScheduler 封装进去,故开发者可根据自己需要进行封装。
