Python zeromq推/拉的Eventlet未按预期工作

我正在尝试使用eventlet和zeromq推/拉套接字创建侦听器/发送器对

代码如下：

import eventlet
from eventlet.green import zmq
from eventlet import sleep as gsleep

#===============================================================================
# config
#===============================================================================
ctx = zmq.Context()
adr = 'tcp://127.0.0.1:5558'

#===============================================================================
# listener
#===============================================================================
def listen(addr):
    l = ctx.socket(zmq.PULL)
    l.connect(addr)
    print 'listening on %s' % addr
    while True:
        data = l.recv()
        print 'something received : %s' % data

eventlet.spawn_n(listen, adr)

#===============================================================================
# sender
#===============================================================================
s = ctx.socket(zmq.PUSH)
s.connect(adr)
while True:
    gsleep(1)
    print "sending something"
    s.send('blabla')

我得到了输出：

listening on tcp://127.0.0.1:5558
sending something
sending something
sending something
sending something
sending something
sending something
...

而不是预期的：

listening on tcp://127.0.0.1:5558
sending something
something received : blabla
sending something
something received : blabla
sending something
something received : blabla
...

我缺少什么？

对于发送方套接字，您应该使用bind而不是connect，因此：

s.connect(adr)

应改为：

s.bind(adr)
