I have the following code:
tries = 10
for n in range(tries):
try:
....
responsedata = requests.get(url, data=data, headers=self.hed, verify=False)
responsedata.raise_for_status()
..
if .... :
break #exit loop condition
except (ChunkedEncodingError, requests.exceptions.HTTPError) as e:
print ("page #{0} run #{1} failed. Returned status code {2}. Msg: {3}. Retry.".format(page, n, responsedata.status_code, sys.exc_info()[0]))
if n == tries - 1:
raise e # exit the process
The prints I see are:
page #53 run #0 failed. Returned status code 502. Msg: <class 'requests.exceptions.HTTPError'>. Retry.
page #1 run #1 failed. Returned status code 500. Msg: <class 'requests.exceptions.ChunkedEncodingError'>. Retry.
While this is Ok it doesn't give me actual information about the problem. The message just tell me the exception title.
If I print the: responsedata.text when exception happens I see:
Returned status code 502. Message is: ...
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"/>
<title>502 - Web server received an invalid response while acting as a gateway or proxy server.</title>

This is a giant message most of it is garbage but it also says: 502 - Web server received an invalid response while acting as a gateway or proxy server.
can I access this message and also print it to my log?

text returns the content of the response, in unicode. Basically, it refers to Binary Response content. Python requests are generally used to fetch the content from a particular resource URI.
You can access the response's status code using responsedata.status_code and its textual description via responsedata.reason (see more in http://docs.python-requests.org/en/master/api/)
