我需要在 django 和 celery 中使用 redis 作为代理来实现 zmq 发布者。但我的客户没有收到任何东西。

任务.py 

  from celery import task
  import zmq


  try:
      context = zmq.Context()
      publisher = context.socket(zmq.PUB)
      publisher.bind('tcp://192.168.0.14:9997')
  except:
      pass

  def app_delivery():
      publisher.send("testid : I am a task ")
      return "Passed"
  @task.task(ignore_result=True)
  def add():
      print "I am going to push message "
      return app_delivery()

视图.py

from django.http import HttpResponse
from notification_core.tasks import add

def resp(request):
    param = request.GET.get('param')
    param = int(param)
    i=0
    while i<param:
        add.delay()
        i+=1
    return HttpResponse("Done")

然后使用命令运行工人—— 

python manage_back.py celery worker --loglevel=info

工人控制台输出

zmq_client 文件 

import zmq
context = zmq.Context()

subscriber = context.socket(zmq.SUB)
subscriber.connect('tcp://192.168.0.14:9997')
subscriber.setsockopt(zmq.SUBSCRIBE, "testid")
while True:
    message = subscriber.recv()
    print "=========="
    print message
    print "=========="

我在客户端没有得到任何输出，需要一些建议。

你是先启动你的客户吗？通常，您希望在 PUB 之前启动 SUB。此外，您可能会发现使用信封很有帮助，尽管在这里看起来有点矫枉过正。

如果您不只是像前面提到的那样简单地吃一个相关的例外，希望这能给我们一些帮助。
