Question

我正在尝试关注example here，但我想要多个听众。如何在没有多线程的情况下创建多个侦听器？

from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream

#Variables that contains the user credentials to access Twitter API
access_token = "<...>"
access_token_secret = "<...>"
consumer_key = "<...>"
consumer_secret = "<...>"

#This is a basic listener that just prints received tweets to stdout.
class StdOutListener(StreamListener):

    def on_data(self, data):
        print data
        return True

    def on_error(self, status):
        print status


if __name__ == '__main__':

    #This handles Twitter authetification and the connection to Twitter Streaming API
    l = StdOutListener()
    auth = OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_token, access_token_secret)
    stream = Stream(auth, l)

    #This line filter Twitter Streams to capture data by the keywords: 'python', 'javascript', 'ruby'
    stream.filter(track=['python', 'javascript', 'ruby'])

    print "Control never seems to arrive here"

    l = StdOutListener()
    auth = OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_token, access_token_secret)
    stream = Stream(auth, l)

    #This line filter Twitter Streams to capture data by the keywords: 'python', 'javascript', 'ruby'
    stream.filter(track=['django', 'angularjs', 'rails'])

我自己也遇到过同样的问题。我的解决方案是在新的命令行进程中运行脚本的不同实例。如果这样做，则需要将脚本的每个“版本”保存为单独的文件。对此可能有一个更好的解决方案，但它是我现在最好的解决方案。

希望这至少有一点帮助。

正如streaming API documentation的function getXmlDom(content) { var xmlDom; try { xmlDom = new ActiveXObject('Msxml2.DOMDocument.6.0'); xmlDom.loadXML(content); } catch (e) { try { xmlDom = new ActiveXObject('Msxml2.DOMDocument.3.0'); xmlDom.loadXML(content); } catch (e2) { xmlDom = (new DOMParser()).parseFromString(content, 'application/xml'); } } return xmlDom; }部分所述，Twitter只允许您连接到流终端。连接尝试次数过多可能导致他们禁止您的IP。
