pubnub python 4 sdk

Question

我刚刚开始使用pubnub。我输入了(4.0)中给出的基本代码，并得到以下错误

错误:pubnub:异步请求异常。'Publish‘对象没有属性’异步‘错误:pubnub:订阅循环中的异常：’发布‘对象没有属性’异步‘警告:pubnub:重新连接策略被禁用，请手动处理重新连接。

就async()而言，有一个可以解决异步错误的疑难解答:输入以下内容

def callback(result, status):
    if status.is_error():
        print("Error %s" % str(status.error_data.exception))
        print("Error category #%d" % status.category)
    else:
        print(str(result))\

但还是不起作用。

这是密码

 from pubnub.callbacks import SubscribeCallback

 from pubnub.enums import PNStatusCategory

 from pubnub.pnconfiguration import PNConfiguration

 from pubnub.pubnub import PubNub

 pnconfig = PNConfiguration()

 pnconfig.subscribe_key = 'demo'
 pnconfig.publish_key = 'demo'

 pubnub = PubNub(pnconfig)


def my_publish_callback(envelope, status):
      # Check whether request successfully completed or not
      if not status.is_error():
          pass  # Message successfully published to specified channel.
      else:
          pass  # Handle message publish error. Check 'category' property to find out possible issue
    # because of which request did fail.
    # Request can be resent using: [status retry];


 class MySubscribeCallback(SubscribeCallback):
      def presence(self, pubnub, presence):
          pass  # handle incoming presence data

      def status(self, pubnub, status):
        if status.category == PNStatusCategory.PNUnexpectedDisconnectCategory:
           pass  # This event happens when radio / connectivity is lost

    elif status.category == PNStatusCategory.PNConnectedCategory:
        # Connect event. You can do stuff like publish, and know you'll get it.
        # Or just use the connected event to confirm you are subscribed for
        # UI / internal notifications, etc
        pubnub.publish().channel("awesomeChannel").message("hello!!").async(my_publish_callback)
        elif status.category == PNStatusCategory.PNReconnectedCategory:
           pass
        # Happens as part of our regular operation. This event happens when
        # radio / connectivity is lost, then regained.
        elif status.category == PNStatusCategory.PNDecryptionErrorCategory:
        pass
        # Handle message decryption error. Probably client configured to
        # encrypt messages and on live data feed it received plain text.

def message(self, pubnub, message):
    pass  # Handle new message stored in message.message


pubnub.add_listener(MySubscribeCallback())
pubnub.subscribe().channels('awesomeChannel').execute()

由于错误来自发布方法，很可能是因为async已更改为pn_async。

注意，到目前为止，这只适用于Python3，因为Python2还没有实现同样的功能。

变化

pubnub.publish().channel("awesomeChannel").message("hello!!").async(my_publish_callback)

至

pubnub.publish().channel("awesomeChannel").message("hello!!").pn_async(my_publish_callback)
