The response returned by urlopen or the HTTPError instance has two useful methods info and geturl and is defined in the module urllib.
This is useful because urlopen or the opener object used may have followed a redirect. It is currently an http. HTTPMessage instance. When you fetch a URL you use an opener an instance of the perhaps confusingly-named urllib. Normally we have been using the default opener - via urlopen - but you can create custom openers. Openers use handlers. You will want to create openers if you want to fetch URLs with specific handlers installed, for example to get an opener that handles cookies, or to get an opener that does not handle redirections.
To create an opener, instantiate an OpenerDirector , and then call. Other sorts of handlers you might want to can handle proxies, authentication, and other common but slightly specialised situations. This means that calls to urlopen will use the opener you have installed. For a more detailed discussion of this subject — including an explanation of how Basic Authentication works - see the Basic Authentication Tutorial.
When authentication is required, the server sends a header as well as the error code requesting authentication. The client should then retry the request with the appropriate name and password for the realm included as a header in the request.
This allows you to specify a default username and password for a URL. This will be supplied in the absence of you providing an alternative combination for a specific realm. This is through the ProxyHandler , which is part of the normal handler chain when a proxy setting is detected. One way to do this is to setup our own ProxyHandler , with no proxies defined.
This is done using similar steps to setting up a Basic Authentication handler:. Currently urllib. However, this can be enabled by extending urllib. The Python support for fetching resources from the web is layered. As of Python 2. This can be useful in applications which have to fetch web pages.
By default the socket module has no timeout and can hang. Currently, the socket timeout is not exposed at the http. However, you can set the default timeout globally for all sockets using. Browser sniffing is a very bad practice for website design - building sites using web standards is much more sensible. Unfortunately a lot of sites still send different versions to different browsers.
