[Fast] Python bindings for Ada, a fast and WHATWG spec-compliant URL parser. This is the URL parser used in projects like Node.js.
pip install can_ada
Binary wheels are available for most platforms. If not available, a C 17-or-greater compiler will be required to build the underlying Ada library.
Unlike the standard library's urllib.parse
module, this library is compliant with the WHATWG URL specification.
import can_ada
urlstring = "https://www.GOoglé.com/./path/../path2/"
url = can_ada.parse(urlstring)
# prints www.xn--googl-fsa.com, the correctly parsed domain name according
# to WHATWG
print(url.hostname)
# prints /path2/, which is the correctly parsed pathname according to WHATWG
print(url.pathname)
import urllib.parse
urlstring = "https://www.GOoglé.com/./path/../path2/"
url = urllib.parse.urlparse(urlstring)
# prints www.googlé.com
print(url.hostname)
# prints /./path/../path2/
print(url.path)
Parsing is simple:
from can_ada import parse
url = parse("https://tkte.ch/search?q=canada")
print(url.protocol) # https:
print(url.host) # tkte.ch
print(url.pathname) # /search
print(url.search) # ?q=canada
You can also modify URLs:
from can_ada import parse
url = parse("https://tkte.ch/search?q=canada")
url.host = "google.com"
url.search = "?q=canada&safe=off"
print(url) # https://google.com/search?q=canada&safe=off
We find that can_ada
is typically ~4x faster than urllib:
