|
|
The **urls** utils module offers a replacement for the urllib2 python library.
|
|
|
|
urllib2 is the python stdlib way to retrieve files from the Internet but it
|
|
lacks some security features (around verifying SSL certificates) that users
|
|
should care about in most situations. Using the functions in this module corrects
|
|
deficiencies in the urllib2 module wherever possible.
|
|
|
|
There are also third-party libraries (for instance, requests) which can be used
|
|
to replace urllib2 with a more secure library. However, all third party libraries
|
|
require that the library be installed on the managed machine. That is an extra step
|
|
for users making use of a module. If possible, avoid third party libraries by using
|
|
this code instead.
