在下面的示例中:
import asyncio
import ipdb
class EchoServerProtocol:
def connection_made(self, transport):
self.transport = transport
def datagram_received(self, data, addr):
message = data.decode()
print('Received %r from %s' % (message, addr))
print('Send %r to %s' % (message, addr))
self.transport.sendto(data, addr)
loop = asyncio.get_event_loop()
ipdb.set_trace(context=21)
print("Starting UDP server")
# One protocol instance will be created to serve all client requests
listen = loop.create_datagram_endpoint( EchoServerProtocol, local_addr=('127.0.0.1', 9999))
transport, protocol = loop.run_until_complete(listen)
try:
loop.run_forever()
except KeyboardInterrupt:
pass
transport.close()
loop.close()
我正试图进入
loop.create_datagram_endpoint( EchoServerProtocol, local_addr=('127.0.0.1', 9999))
了解它的内部行为。
然而,当我尝试进入协程时,调试器跳过它,就好像按下了n
而不是s
。
> ../async_test.py(18)<module>()
17 # One protocol instance will be created to serve all client requests
---> 18 listen = loop.create_datagram_endpoint( EchoServerProtocol, local_addr=('127.0.0.1', 9999))
19 transport, protocol = loop.run_until_complete(listen)
ipdb> s
> ../async_test.py(19)<module>()
18 listen = loop.create_datagram_endpoint( EchoServerProtocol, local_addr=('127.0.0.1', 9999))
---> 19 transport, protocol = loop.run_until_complete(listen)

这种行为出现在 PyCharm(2016 2.3 社区版)IDE 中。
我希望能够结束 这里,并能够进一步地跟踪代码。
