超玉米服务器钩子

Question

我已经看到，gunicorn提供了服务器钩子，我们可以用它来连接各种服务器事件，我在超级玉米中寻找同样的东西，因为它是以gunicorn为灵感的，但是超级玉米文档在这个问题上没有任何帮助，而且我还没有找到实现这个的人。

hyperconr.config.py

import multiprocessing as mp
import os
print( (mp.cpu_count() * 2) + 1)

accesslog = "-"
backlog = 500
bind = "0.0.0.0:8000"
statsd_host = os.environ.get("STASD_HOST")
workers = 3
max_requests = 2

"""
This module is the entry point for the API.
This will contain all of the middleware and routes and database initialization
"""

from starlette.applications import Starlette
from starlette.routing import Route

# from sample_project import HealthCheckAPI
from src.health_check import HealthCheckAPI

routes = [
    Route(f"/health-check", HealthCheckAPI)
]
app = Starlette(debug=True, routes=routes)
# app = AsyncioWSGIMiddleware(app)

if __name__ == "__main__":
    from hypercorn.config import Config

    config = Config()
    config.bind = ["localhost:8077"]
    config.debug = True
    import asyncio

    from hypercorn.asyncio import serve

    asyncio.run(serve(app, config))

 hypercorn -c file:config/hypercorn.config.py  src.application:app

下面是带有服务器钩子的gunicorn服务器的示例配置。

import multiprocessing as mp
import os
print( (mp.cpu_count() * 2) + 1)

accesslog = "-"
backlog = 500
bind = "0.0.0.0:8000"
statsd_host = os.environ.get("STASD_HOST")
workers = 3
max_requests = 2

def on_starting(server):
    # register some variables here
    print(server)
    print("Starting Flask application")

def on_exit(server):
    # perform some clean up tasks here using variables from the application
    print("Shutting down Flask application")

def worker_exit(server, worker):
    print("Worker exiting")
    print(worker)

def nworkers_changed(server, new_value, old_value):
    print("n worker",new_value)

Answer 1

超级玉米目前没有任何服务器钩子。然而，on_starting和on_exit被ASGI寿命事件所容纳。当使用Starlette时，这些是on_startup和on_shutdown 事件。
