我尝试在我的sanic应用程序中使用异步原始套接字,Python 3.6 并且真的很惊讶来自异步函数curio在 sanic 异步上下文中不起作用。最小的概念证明:

import curio
from sanic import Sanic
from sanic.response import text
app = Sanic(__name__)


@app.route('/')
async def index(request):
    sock = await curio.open_connection("google.com", 443, ssl=True)
    resp = await sock.recv(1024)
    return text(resp)


app.run(host="0.0.0.0", port=5001)

此代码在任何 http 请求上生成核心转储

为了将这个问题与 github 问题联系起来,OP 已经提出了这个问题。

在 sanic 控制器中使用古玩

总结(来自问题评论):

来自 Curio 官方文档:“Curio 还可以将工作提交给 asyncio 事件循环,前提是它必须在不同的线程中单独运行。”

看看这个问题

Curio 对事件的主要实现是队列,而不是事件循环。您正在尝试在运行 Sanic(和事件循环)的同一线程中生成任务。
