保持运行/重启 python 脚本 (TwitterAPI) [英] KeepRunning/Restarting a python script (TwitterAPI)

问题描述

你好 Stackoverflow 社区，

Hi Stackoverflow community,

我有一个关于保持 Python 继续运行以从 Twitter Streaming API 流式传输数据的问题.

I have a question about keeping the Python keep running to streaming data from Twitter Streaming API.

以下是我使用的 Twitter Streaming API 的基本版本

Below is the basic version of the Twitter Streaming API I used

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

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

##########################################################
# listener received tweets to stdout - MINUTE
class StdOutListener(StreamListener):

    def on_data(self, data):
        print(data)
        return True

    def on_error(self, status):
        print(status)

##########################################################
# Main program
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)

    # Initiate the connection to Streaming API
    twitter_stream = Stream(auth, l)

    # Get a sample of the public data following through Twitter
    twitter_stream.sample()

有时，流媒体停止工作(由于 Twitter 重启 API 或文件系统，我不确定)，错误如下图所示

Sometimes, the streaming stop working (due to Twitter restart API, or file system, I am not sure), the error is like in the pictures below

我的问题是我们是否有任何技术来保持 python 文件运行:
- 就像构建第二个文件来测试文件 1 是否正在运行，然后在每次文件 1 失败时激活文件 1
- 或者在文件 1 中集成一些技术使其重新启动
- 或者更多的建议.

My question is that do we have any technique to keep a python file running:
- Like building a second file that test if file 1 is running, then activate file 1 everytime file 1 fails
- Or integrate some techniques in file 1 to make it restart itself
- Or some more suggestion.

我能听听你的意见吗?要是有代码就好多了

Can I have your opinion. It is a lot better if it comes the code

谢谢.

推荐答案

我已经将 retrying 库用于 Python Twitter 机器人，效果很好.

I've used the retrying library to good effect with python Twitter bots.

https://pypi.python.org/pypi/retrying

有代码示例，但它几乎就像在您的函数上使用 @retry 装饰器一样简单.您可以在类的方法中使用它:

Has code examples, but it's pretty much as simple as using a @retry decorator on your function. You could use it on the methods for your class:

@retry
def on_data():
    <code>

NB twitter 会记录您对其 API 的调用次数，因此您必须小心不要用完它.

NB twitter logs how many calls you make to its API so you have to be careful that this doesn't use it up.

根据我的经验，如果你需要从阻止你的人那里得到一条推文，这无济于事，因为它会一直失败，所以你需要采取一些措施来解决这个问题.

From my experiences, if you need to get a tweet from someone who has blocked you, this won't help because it will keep failing, so you'll need to put something in to deal with this.
