问题:

In my python app I try to open a https url, but I get:

 File "C:\Python26\lib\urllib.py", line 215, in open_unknown     raise IOError, ('url error', 'unknown url type', type) IOError: [Errno url error] unknown url type: 'https'

my code:

import urllib def generate_embedded_doc(doc_id):     url = "https://docs.google.com/document/ub?id=" + doc_id + "&embedded=true"     src = urllib.urlopen(url).read()     ...     return src

回答1:

urllib and Python 2.6 have SSL support and your code example works fine for me. Probably your Python is built without SSL support? Try to reinstall Python 2.6 (or better, 2.7) and use the original build from python.org.

On Google App Engine, try to use the API directly:

from google.appengine.api import urlfetch  url = "https://www.google.com/" result = urlfetch.fetch(url) if result.status_code == 200:   doSomethingWithResult(result.content)

To have SSL support you need to compile Python with OpenSSL. For example under ubuntu lucid you must install the module libcurl4-openssl-dev then re-build Python.
