Question

我有以下Python脚本使用Tweepy来获取推文并使用PyMongo将它们存储到MongoDB中。发生什么事情就是每当我运行这个脚本时，我的MongoDB实例都会关闭，脚本会因错误而停止。我不知道为什么会发生这种情况，因为即使脚本正在终止或者Tweepy遇到错误，它也不应该影响MongoDB的运行状态。此行被标识为第一个触发点：stream.filter(locations=[-119.970703, 48.994636, -109.951172, 59.955010])

脚本

import tweepy, sys, json, traceback
from bson.json_util import loads as json_to_bson
from hashlib import sha1
from datetime import datetime
from pymongo import MongoClient
from time import sleep, strptime, mktime

client = MongoClient()
mode = None

class Stream(tweepy.StreamListener):
    def on_status(self, data):
        save(data)

    def on_error(self, code):
        pause()

def now():
    return str(datetime.now().strftime("%Y-%m-%d %H:%M:%S"))

def pause():
    sys.stdout.flush()
    sleep((60*15)+5)

def save(data):
    bson = json_to_bson(json.dumps(data._json))
    tweet_date = strptime(bson['created_at'], "%a %b %d %H:%M:%S +0000 %Y")
    tweet_date = str(datetime.fromtimestamp(mktime(tweet_date)))

    bson['created_at'] = tweet_date
    bson['text_hash'] = sha1(bson['text'].encode('punycode')).hexdigest()
    bson['collected_at'] = now()
    bson['collection_type'] = mode

    if client.grebe.tweets.find_one({'text_hash': bson['text_hash']}) == None:
        client.grebe.tweets.insert_one(bson)

def api():
    CONSUMER_KEY = 'key'
    CONSUMER_SECRET = 'secret'
    ACCESS_TOKEN_KEY = 'tokenkey'
    ACCESS_TOKEN_SECRET = 'tokensecret'

    auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
    auth.set_access_token(ACCESS_TOKEN_KEY, ACCESS_TOKEN_SECRET)
    return tweepy.API(auth)

def main():
    mystream = Stream()
    stream = tweepy.Stream(api().auth, mystream)
    stream.filter(locations=[-119.970703, 48.994636, -109.951172, 59.955010])

main()
