Module urllib :: Class URLopener

Class URLopener

Known Subclasses:: FancyURLopener

Class to open URLs. This is a class rather than just a subroutine because we may need more than one set of global protocol-specific options. Note -- this is a base class for those who don't want the automatic handling of errors type 302 (relocated) and 401 (authorization needed).

	`http_error_default(self, url, fp, errcode, errmsg, headers)` Default error handler: close the connection and raise IOError.
	`open(self, fullurl, data)` Use URLopener().open(file) instead of open(file, 'r').
	`open_data(self, url, data)` Use "data" URL.
