规范化HTTP URI

该寻址创业板将这些归为你:

require 'addressable/uri'

# normalize relative paths
uri = Addressable::URI.parse('http://example.com/foo/bar/../jim/jam')
puts uri.normalize.to_s #=> "http://example.com/foo/jim/jam"

# removes trailing ?
uri = Addressable::URI.parse('http://example.com/foo/jim/jam?')
puts uri.normalize.to_s #=> "http://example.com/foo/jim/jam"

# leaves empty parameters alone
uri = Addressable::URI.parse('http://example.com/foo/jim/jam?jim')
puts uri.normalize.to_s #=> "http://example.com/foo/jim/jam?jim"

# remove specific query parameters
uri = Addressable::URI.parse('http://example.com/foo/jim/jam?autho=&file=jam')
cleaned_query = uri.query_values
cleaned_query.delete('autho')
cleaned_query.delete('file')
uri.query_values = cleaned_query
uri.normalize.to_s #=> "http://example.com/foo/jim/jam"
