How to solve the 10054 error

问题:

I'm using an app provided by some website to collect some data from the website periodly, say, 30s a time. The returned response is then recorded in database.

I use the requests modular by import requests and write codes to catch Exception. The codes for the main function are as following:

def get_response(self):
    try:
       response = requests.get(self.request_url)
       if response.status_code == 200:
          return response.json()
       except Exception as e:
          msg = "Exception is:\n %s \n" % e
          print msg

The above function works quite well for the first several hours. The function can also recover from some exceptions like: ('Connection aborted.', BadStatusLine("''",))
or ('Connection aborted.', error(10053, '')) It omits the exception (by recording a Null in database) and continues to get the response of next period.

However, the function stops working when encoutering a 10054 error.

Exception is:
 ('Connection aborted.', error(10054, '')) 

I check the database to find that all the response is Null after the time that the 10054 error comes. I firstly guess that the website may breakdown, thus no response is received. But when I manually restart the function, it starts to get response again. So that's no realated with breakdown of the website.

I search in stackoverflow and find: Errno 10054 An existing connection was forcibly closed by the remote host. But I don't know how to resolve it.

Could you please provide some solotion to this problem?(ideally speaking) or provide some solution to restart the function without manually restarting? (It looks like once I restart the funtion and it works again.)

Thanks in advance.

The web server actively rejected your connection. That's usually because it is congested, has rate limiting or thinks that you are launching a denial of service attack. If you get this from a server, you should sleep a bit before trying again. In fact, if you don't sleep before retry, you are a denial of service attack. The polite thing to do is implement a progressive sleep of, say, (1,2,4,8,16,32) seconds.
