python - 相対 URL パスを絶対パスに解決する

Question

このように動作するPythonのライブラリはありますか?

>>> resolvePath("http://www.asite.com/folder/currentpage.html", "anotherpage.html")
'http://www.asite.com/folder/anotherpage.html'
>>> resolvePath("http://www.asite.com/folder/currentpage.html", "folder2/anotherpage.html")
'http://www.asite.com/folder/folder2/anotherpage.html'
>>> resolvePath("http://www.asite.com/folder/currentpage.html", "/folder3/anotherpage.html")
'http://www.asite.com/folder3/anotherpage.html'
>>> resolvePath("http://www.asite.com/folder/currentpage.html", "../finalpage.html")
'http://www.asite.com/finalpage.html'

Answer 1

はい、Python 3 用urlparse.urljoinの orがあります。urllib.parse.urljoin

>>> try: from urlparse import urljoin # Python2
... except ImportError: from urllib.parse import urljoin # Python3
...
>>> urljoin("http://www.asite.com/folder/currentpage.html", "anotherpage.html")
'http://www.asite.com/folder/anotherpage.html'
>>> urljoin("http://www.asite.com/folder/currentpage.html", "folder2/anotherpage.html")
'http://www.asite.com/folder/folder2/anotherpage.html'
>>> urljoin("http://www.asite.com/folder/currentpage.html", "/folder3/anotherpage.html")
'http://www.asite.com/folder3/anotherpage.html'
>>> urljoin("http://www.asite.com/folder/currentpage.html", "../finalpage.html")
'http://www.asite.com/finalpage.html'

コピー アンド ペーストの場合:

try:
    from urlparse import urljoin  # Python2
except ImportError:
    from urllib.parse import urljoin  # Python3
