我正在尝试在ZMQ消息通过时向我的龙卷风应用程序添加回调。我得到了:
*** TypeError:参数必须是int,或者有fileno()方法。
当尝试创建ZMQStream对象时,我已经读过这种情况,当没有安装zmq ioloop时,我在我的程序的第一行从zmq调用ioloop.install()。调用 zmq.eventloop.ioloop.IOLoop.instance()和tornado IOLoop.instance()返回相同的对象。
有趣的代码是:
launch.py
import logging
import os
import tornado
import zmq
from zmq.eventloop import ioloop
from tornado.httpserver import HTTPServer
from web.apiserver import Userform, UploadHandler, UserHandler, LoginHandler
application = tornado.web.Application([
(r"/upload/(?P<token>\w+)", UploadHandler),
# .....
], debug=True)
if __name__ == "__main__":
if os.geteuid() != 0:
exit('Por favor, ejecute como root')
ioloop.install()
logging.basicConfig(filename=r'/tmp/tornado.log', level=logging.INFO)
httpsserver = HTTPServer(application, ssl_options={
"certfile": "web/server.crt",
"keyfile": "web/server.key",
})
httpsserver.listen(8888)
zmq.eventloop.IOLoop.instance().start()
server.py
thread_pool = ThreadPoolExecutor(max_workers=4)
context = zmq.Context()
class UploadHandler(RequestHandler):
# .......
# after some callback magic we end up here:
def watch_job(self, ip, port):
subscriber_socket = context.socket(zmq.SUB)
subscriber_socket.connect("tcp://%s:%s" % (ip, port))
subscriber_socket.setsockopt(zmq.SUBSCRIBE, 'client')
import ipdb; ipdb.set_trace()
stream_sub = ZMQStream(subscriber_socket, IOLoop.instance()) #<--- Here TypeError
stream_sub.on_recv(self.check_job_progress)
我尝试过的其他事情:
答案 0 :(得分:2)
对zmq.ioloop.install()
的调用需要更早。在调试模式下创建Application
将初始化默认的IOLoop,因此您必须在构造Application
之前安装ZMQ IOLoop。
