使用 Python Tweepy 的 Twitter Streaming API

Question

I've been playing with the Twitter Streaming API using the Tweepy library. I started by following my own account and streaming my own tweets as I posted them, which worked fine.

I then attempted to stream a fairly large region's tweets ([30,-85,31,-84]), to which I initially seemed to receive no data. I then started receiving 'Location Deletion Notices', or 'scrub_geo' messages, and have only ever received those since. I changed my code back to the previously working follow code, but I continue to receive 'scrub_geo' messages and not statuses from my profile.

Here's the script I'm using:

# Import the necessary methods from tweepy library
from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream

# Other libs
import json

# Variables that contains the user credentials to access Twitter API
access_token = "<my_access_token>"
access_token_secret = "<my_secret_token>"
consumer_key = "<my_consumer_key>"
consumer_secret = "<my_consumer_secret>"


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

    def on_data(self, data):
        #try:
        #    json_data = json.loads(data)
        #    print json_data['created_at'] + " " + data['text']
        #except:
        print "Data " + str(data)
        return True

    def on_error(self, status):
        print "Error " + str(status)
        if status == 420:
            print("420 error.")
            return False


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)

    # Start streaming with right parameters
    #tallahassee=[30,-85,31,-84]
    #stream.filter(locations=tallahassee)           <---- previously used 
    stream.filter(follow="<my_user_id>")

Answer 1

Your coordinates are reversed. Since we're dealing with GeoJSON always do (long,lat,alt) or (x,y,z)

So you'll need to provide tallahassee=[-85,30,-84,31] . Always provide longitude first same as you would do (x,y) in math.

There are some places, like google maps, that do latitude first. You just have to be careful as to which proper format you're dealing with.
