python - Python で URL から utm_* パラメータを削除する

Question

URL のリストからすべての utm_* パラメータを削除しようとしています。私が見つけた最も近いものはこれです: https://gist.github.com/626834。

何か案は？

Answer 1

少し長いですが、url* モジュールを使用し、re を避けています。

from urllib import urlencode
from urlparse import urlparse, parse_qs, urlunparse

url = 'http://whatever.com/somepage?utm_one=3&something=4&utm_two=5&utm_blank&something_else'

parsed = urlparse(url)
qd = parse_qs(parsed.query, keep_blank_values=True)
filtered = dict( (k, v) for k, v in qd.iteritems() if not k.startswith('utm_'))
newurl = urlunparse([
    parsed.scheme,
    parsed.netloc,
    parsed.path,
    parsed.params,
    urlencode(filtered, doseq=True), # query string
    parsed.fragment
])

print newurl
# 'http://whatever.com/somepage?something=4&something_else'

Answer 2

import re
from urlparse import urlparse, urlunparse

url = 'http://www.someurl.com/page.html?foo=bar&utm_medium=qux&baz=qoo'
parsed_url = list(urlparse(url))
parsed_url[4] = '&'.join(
    [x for x in parsed_url[4].split('&') if not re.match(r'utm_', x)])
utmless_url = urlunparse(parsed_url)

print utmless_url  # 'http://www.someurl.com/page.html?foo=bar&baz=qoo'

Answer 3

これはどう。素晴らしくシンプル：

url = 'https://searchengineland.com/amazon-q3-ad-revenues-surpass-1-billion-roughly-2x-early-2016-285763?utm_source=feedburner&utm_medium=feed&utm_campaign=feed-main'

print url[:url.find('?utm')]

Answer 4

シンプルで機能し、あなたが投稿したリンクに基づいていますが、それは本当です...だから、私が考えられない何らかの理由で壊れないかどうかはわかりません:)

import re

def trim_utm(url):
    if "utm_" not in url:
        return url
    matches = re.findall('(.+\?)([^#]*)(.*)', url)
    if len(matches) == 0:
        return url
    match = matches[0]
    query = match[1]
    sanitized_query = '&'.join([p for p in query.split('&') if not p.startswith('utm_')])
    return match[0]+sanitized_query+match[2]

if __name__ == "__main__":
    tests = [   "http://localhost/index.php?a=1&utm_source=1&b=2",
                "http://localhost/index.php?a=1&utm_source=1&b=2#hash",
                "http://localhost/index.php?a=1&utm_source=1&b=2&utm_something=no#hash",
                "http://localhost/index.php?a=1&utm_source=1&utm_a=yes&b=2#hash",
                "http://localhost/index.php?utm_a=a",
                "http://localhost/index.php?a=utm_a",
                "http://localhost/index.php?a=1&b=2",
                "http://localhost/index.php",
                "http://localhost/index.php#hash2"
            ]

    for t in tests:
        trimmed = trim_utm(t)
        print t
        print trimmed
        print
