Python3的urllib.parse常用函数小结(urlencode,quote,quote_plus,unquote,unquote_plus等)

>>> 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)>>> parseResultParseResult(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'#注意：加号会被解码，可能有时并不是我们想要的>>> 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']}

>>> 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'1+2'>>> parse.unquote('1+2')  #把加号解码为空格'1 2'
