使用我的flask-socketio应用程序时，我正在尝试在收到新推文时更新所有连接的客户端。以下是我的代码。
from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream
from tweepy import API
access_token = "tkndfkdj"
access_token_secret = "aldkjfd;"
consumer_key = "saldkjfa;"
consumer_secret = "dkaljfad"
app = Flask(__name__)
socketio = SocketIO(app,async=True)
tweet_count = 0
class MyListener(StreamListener):
def on_data(self, data):
print(data)
return True
def on_error(self, status):
print(status)
@socketio.on('connect', namespace='/test')
def test_connect():
print('client connected !!!')
global myStream
auth = OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = API(auth)
global myStream
myStream = Stream(auth = api.auth, listener=MyListener())
myStream.filter(track=['#python','#java'],async=True)
if __name__ == '__main__':
socketio.run(app,host='0.0.0.0',port=9000, debug=True)
在上面的代码中，我在myStream.filter(track=['#python','#java'],async=True)函数中添加行test_connect后收到错误。

答案 0 :(得分：1)
由于您正在使用gevent并通过tweepy进行网络连接，因此您需要修补Python标准库，以使其与gevent的异步循环兼容。
这是您需要添加到猴子补丁的代码：
from gevent import monkey
monkey.patch_all()
这需要在您的主脚本中完成，并且高于所有其他导入。如果你已经进行了猴子修补，那么错误很可能是因为在其他导入之后进行猴子修补太晚了。
