Python tweepy写入到sqlite3 db

问题描述

我下面的脚本(摘自各种在线资源)没有写入数据库。我没有收到任何错误，如果我注释掉数据库行，则它会毫无问题地输出到控制台。

数据库存在，它有2个字段，可由我写入...有什么想法吗？

已更新以下代码

#!/usr/bin/env python

import sys
import tweepy
from textwrap import TextWrapper
import sqlite3

CONSUMER_KEY = ''
CONSUMER_SECRET = ''
ACCESS_KEY = ''
ACCESS_SECRET = ''


auth1 = tweepy.auth.OAuthHandler(CONSUMER_KEY,CONSUMER_SECRET)
auth1.set_access_token(ACCESS_KEY,ACCESS_SECRET)
api = tweepy.API(auth1)
conn = sqlite3.connect('twitter.db')
cur = conn.cursor()

class StreamListener(tweepy.StreamListener):
    status_wrapper = TextWrapper(width=60, initial_indent='    ', subsequent_indent='    ')



    def on_status(self, status):
        try:
            cur.execute('INSERT INTO tweets (text, date) VALUES (?, ?)' ,(status.text,))
            print self.status_wrapper.fill(status.text)
            print '
 %s  %s  via %s
' % (status.author.screen_name, status.created_at, status.source)
            conn.commit()   
        except Exception, e:
            print >> sys.stderr, 'Encountered Exception:', e

    def on_error(self, status_code):
            print >> sys.stderr, 'Encountered error with status code:', status_code
            return True # Don't kill the stream

    def on_timeout(self):
            print >> sys.stderr, 'Timeout...'
            return True # Don't kill the stream


streamer = tweepy.Stream(auth1, StreamListener(), timeout=None)
setTerms = ['news','hello']
streamer.filter(setTerms)

解决方案

首先，修复缩进。您不会收到任何错误，因为您显式地让它们静默了！使用

except Exception, e:
    # Catch any unicode errors while printing to console
    # and just ignore them to avoid breaking application.
    pass

这将捕获try: except:块中发生的任何异常。阅读Python教程是一项good start to learn more about exceptions.
