tweepy将twitter标签流收集到csv文件

Question

我试图运行此脚本来收集流式tweet实时特定标签并将它们保存在csv文件中。这是我目前的脚本。它会打印到控制台并创建一个包含作者，日期，文本行的csv文件。但流传送的tweets不会保存到csv。

import sys 
import tweepy 
import csv 

#pass security information to variables 
consumer_key = "" 
consumer_secret = "" 
access_key = "" 
access_secret = "" 


#use variables to access twitter 
auth = tweepy.OAuthHandler(consumer_key, consumer_secret) 
auth.set_access_token(access_key, access_secret) 
api = tweepy.API(auth) 

#create an object called 'customStreamListener' 


class CustomStreamListener(tweepy.StreamListener): 

def on_status(self, status): 
    print status.author.screen_name, status.created_at, status.text 
    with open('file.csv', 'w') as f: 
       f.write('Author,Date,Text') 
       writer = csv.writer(f) 
       writer.writerow([status.author.screen_name, status.created_at, status.text]) 


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 




streamingAPI = tweepy.streaming.Stream(auth, CustomStreamListener()) 
streamingAPI.filter(track=['russia'])

您需要在on_status之外使用全局变量编写器。

例如（使用您的代码）

class CustomStreamListener(tweepy.StreamListener): 
global writer 
     writer = csv.writer(open('file.csv', 'w+')) 
     w.writerow(('Author', 'Date', 'Text')) 
def on_status(self, status): 
    print status.author.screen_name, status.created_at, status.text 
    writer.writerow(status.author.screen_name, status.created_at, status.text)
