python 中的异步服务器代码在使用 asyncio.start_server 时将无法工作

async server code in python wont work when using asyncio.start_server

这是异步的 python,但是当我向它发送请求并使用 time.sleep(5) 进行并行测试时它不会工作,但它是顺序的并且请求顺序执行:

def main(*args):    
    loop = get_event_loop()

    coro = asyncio.start_server(handle_echo, '127.0.0.1', 50008,loop=loop)
    srv = loop.run_until_complete(coro)   
def handle_echo(reader, writer):
    data = yield from reader.read(500)
    message = data.decode(encoding='utf-8')            

    nameindex=('name="calculator2"' in message)
    if nameindex:
        time.sleep(5)
        writer.write("Content-Length: 1\r\n\r\n2".encode())
        yield from writer.drain()
    else:
        writer.write("Content-Length: 1\r\n\r\n1".encode())
        yield from writer.drain()

    print("Close the client socket")
    writer.close()

替换:

time.sleep(5)

与:

await asyncio.sleep(5)
