Python3 urllib.parse共通関数の例(qbit)

urlパラメータを取得します.

>>> from urllib import parse
>>> url = r'https://docs.python.org/3.5/search.html?q=parse&check_keywords=yes&area=default'
>>> parseResult = parse.urlparse(url)
>>> parseResult
ParseResult(scheme='https', 
            netloc='docs.python.org', 
            path='/3.5/search.html', 
            params='', 
            query='q=parse&check_keywords=yes&area=default', 
            fragment='')
>>> param_dict = parse.parse_qs(parseResult.query)
>>> param_dict
{'q': ['parse'], 'check_keywords': ['yes'], 'area': ['default']}
>>> q = param_dict['q'][0]
>>> q
'parse'
#  ：      ，            
>>> parse.parse_qs('proxy=183.222.102.178:8080&task=XXXXX|5-3+2')
{'proxy': ['183.222.102.178:8080'], 'task': ['XXXXX|5-3 2']}

なぜurldecodeがないのか聞きたいなら、上記の例を5回見てみましょう.^^;

parse_qs/parse_qsl

>>> from urllib import parse
>>> parse.parse_qs('action=addblog&job=modify&tid=1766670')            # 1
{'tid': ['1766670'], 'action': ['addblog'], 'job': ['modify']}        #    3     
>>> parse.parse_qsl('action=addblog&job=modify&tid=1766670')
[('action', 'addblog'), ('job', 'modify'), ('tid', '1766670')]        # 3
>>> dict(parse.parse_qsl('action=addblog&job=modify&tid=1766670'))    #    1     
{'tid': '1766670', 'action': 'addblog', 'job': 'modify'}

urlencode

>>> from urllib import parse
>>> query = {
    'name': 'walker',
    'age': 99,
    }
>>> parse.urlencode(query)
'name=walker&age=99'

quote/quote_plus

>>> from urllib import parse
>>> parse.quote('a&b/c')    #     
'a%26b/c'
>>> parse.quote_plus('a&b/c')    #     
'a%26b%2Fc'

unquote/unquote_plus

from urllib import parse
>>> parse.unquote('1+2')    #     
'1+2'
>>> parse.unquote('1+2')    #        
'1 2'

ドメイン名コード敏感語マスクを避ける.

>>> ''.join('%' + ('%x'%ord(ch)).upper() for ch in 'github.com')
'%67%69%74%68%75%62%2E%63%6F%6D'
