[Tutor] urllib2 sslerror

[Johan Geldenhuys]

Hi everybody,

Almost weekend, hang in there.

I need some advice and hope somebody can help me.

I have the follow piece of code that I use to get some data from a https
webpage.

-------------------------------------------------------
< some other stuff up here>
try:
    return_object = urllib2.urlopen(theurl)
    html_content = return_object.read()
                      
    now = time.strftime("%Y%m%d%H%M%S")
    img_file = "%s_%s.jpg"% (location, now)
    f = open(img_file, 'wb')
    f.write(html_content)
    f.close()
    file = img_file
except Exception, e:
	print e

<some other stuff down here>
-------------------------------------------------------

Sometimes I get the following error and I don't know why. It occurs very
randomly and is hard or nearly impossible to reproduce (maybe there is
somebody who knows how to create it).

-------------------------------------------------------
Traceback (most recent call last):

sslerror: (5, 'EOF occurred in violation of protocol')
------------------------------------------------------------


Any idea why it happens randomly and how I can check the cause?
I read on a Google search page that one guy had the same issue and traced it
back to some characters in the data he was receiving. Could that cause it?

Thanks in advance
