urllib

somehow I can't download files trough a proxyserver, and I don't know what i have done wrong. I just get a timeout. Any advice? import urllib.request urllib.request.ProxyHandler({"http" : "myproxy:123"}) urllib.request.urlretrieve("http://myfile", "file.file") You need to use your proxy-object, not just instanciate it (you created an object, but didn't assign it to a variable and therefore can't use it). Try using this pattern: #create the object, assign it to a variable proxy = urllib.request.ProxyHandler({'http': '127.0.0.1'}) # construct a new opener using your proxy settings opener =

Here is my problem with urllib in python 3. I wrote a piece of code which works well in Python 2.7 and is using urllib2. It goes to the page on Internet (which requires authorization) and grabs me the info from that page. The real problem for me is that I can't make my code working in python 3.4 because there is no urllib2, and urllib works differently; even after few hours of googling and reading I got nothing. So if somebody can help me to solve this, I'd really appreciate that help. Here is my code: request = urllib2.Request('http://mysite/admin/index.cgi?index=127') base64string = base64

Python's urllib.quote and urllib.unquote do not handle Unicode correctly in Python 2.6.5. This is what happens: In [5]: print urllib.unquote(urllib.quote(u'Cataño')) --------------------------------------------------------------------------- KeyError Traceback (most recent call last) /home/kkinder/<ipython console> in <module>() /usr/lib/python2.6/urllib.pyc in quote(s, safe) 1222 safe_map[c] = (c in safe) and c or ('%%%02X' % i) 1223 _safemaps[cachekey] = safe_map -> 1224 res = map(safe_map.__getitem__, s) 1225 return ''.join(res) 1226 KeyError: u'\xc3' Encoding the value to UTF8 also does

I would like to POST multipart/form-data encoded data. I have found an external module that does it: http://atlee.ca/software/poster/index.html however I would rather avoid this dependency. Is there a way to do this using the standard libraries? thanks Martin v. Löwis The standard library does not currently support that . There is cookbook recipe that includes a fairly short piece of code that you just may want to copy, though, along with long discussions of alternatives. ticapix It's an old thread but still a popular one, so here is my contribution using only standard modules. The idea is the

I am using urllib.urlencode to build web POST parameters, however there are a few values I only want to be added if a value other than None exists for them. apple = 'green' orange = 'orange' params = urllib.urlencode({ 'apple': apple, 'orange': orange }) That works fine, however if I make the orange variable optional, how can I prevent it from being added to the parameters? Something like this (pseudocode): apple = 'green' orange = None params = urllib.urlencode({ 'apple': apple, if orange: 'orange': orange }) I hope this was clear enough, does anyone know how to solve this? You'll have to add
