1、获取url参数。>>> 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‘>>> from urllib import parse
>>> query = {
‘name‘: ‘walker‘,
‘age‘: 99,
}
>>> parse.urlencode(query)
‘name=walker&age=99‘>>> from urllib import parse
>>> parse.quote(‘a&b/c‘) #未编码斜线
‘a%26b/c‘
>>> parse.quote_plus(‘a&b/c‘) #编码了斜线
‘a%26b%2Fc‘from urllib import parse
>>> parse.unquote(‘1+2‘) #不解码加号
‘a&b/c‘
>>> parse.unquote(‘1+2‘) #把加号解码为空格
‘1 2‘
如果你还想问为什么没有urldecode——再把示例1看五遍。^_^
