I had an application that was downloading a .CSV file from a password-protected website then processing it futher.
I was using FancyURLOpener, and simply hardcoding the username and password. (Obviously, security is not a high priority in this particular instance).
Since downloading Python 3.1.2, this code has stopped working. Does anyone know of the changes that have happened to the implementation?
Here is a cut down version of the code:
import urllib.request;
class TracOpener (urllib.request.FancyURLopener) :
def prompt_user_passwd(self, host, realm) :
return ('andrew_ee', '_my_unenctryped_password')
csvUrl='http://mysite/report/19?format=csv@USER=fred_nukre'
opener = TracOpener();
f = opener.open(csvUrl);
s = f.read();
f.close();
s;
For the sake of completeness, here's the entire call stack:
