How to handle IncompleteRead: in python

The link you included in your question is simply a wrapper that executes urllib's read() function, which catches any incomplete read exceptions for you. If you don't want to implement this entire patch, you could always just throw in a try/catch loop where you read your links. For example:

try:
    page = urllib2.urlopen(urls).read()
except httplib.IncompleteRead, e:
    page = e.partial

for python3

try:
    page = request.urlopen(urls).read()
except (http.client.IncompleteRead) as e:
    page = e.partial

Note this answer is Python 2 only (it was published in 2013)

I find out in my case : send HTTP/1.0 request , adding this , fix the problem.

import httplib
httplib.HTTPConnection._http_vsn = 10
httplib.HTTPConnection._http_vsn_str = 'HTTP/1.0'

after I do the request :

req = urllib2.Request(url, post, headers)
filedescriptor = urllib2.urlopen(req)
img = filedescriptor.read()

after I back to http 1.1 with (for connections that support 1.1) :

httplib.HTTPConnection._http_vsn = 11
httplib.HTTPConnection._http_vsn_str = 'HTTP/1.1'

the trick is use http 1.0 instead the default http/1.1 http 1.1 could handle chunks but for some reason webserver don't , so we do the request in http 1.0

for Python3, it will tell you

ModuleNotFoundError: No module named 'httplib'

then try to use http.client Module it will solve the problem

import http.client as http
http.HTTPConnection._http_vsn = 10
http.HTTPConnection._http_vsn_str = 'HTTP/1.0'
