python轻量级框架

Responder框架

responder是@kennethreitz新开发的一个项目，是一个基于 Python 的 HTTP 服务框架. 底层用了 Starlette 的框架, Starlette 是一款轻量级的 ASGI 框架/工具包，可以用 Starlette 构建高性能的异步 IO 服务.

示例代码如下:

#! /usr/bin/env python

api = responder.API()

@api.route("/{greeting}")
async def greet_world(req, resp, *, greeting):
    resp.text = f"{greeting}, world"

@api.route("/")
def hello(req, resp):

    # 作为后台任务执行
    @api.background.task
    def sleep(s=10):
        time.sleep(s)
        print("slept!")

    sleep()
    resp.content = "processing"

class Query(graphene.ObjectType):
    hello = graphene.String(name=graphene.String(default_value="stranger"))

    def resolve_hello(self, info, name):
        return f"Hello {name}"

schema = graphene.Schema(query=Query)
view = responder.ext.GraphQLView(api=api, schema=schema)

api.add_route("/graph", view)

if __name__ == "__main__":
    api.run()
