1.urllib.parse: for parsing URL

2. Use the urlparse () function to parse the string

3. Use urlunparse () function can be the object or a tuple ParseResult restored to promote wear URL from

4.parse_qs (), parse_qsl () is used to resolve the query string to get a dictionary or list

5.urlencode (): to restore a list or dictionary into the query string

import urllib.parse as up

url = 'https://blog.csdn.net/happyk213'
# uv = up.urlparse(url)
# print(uv)
# print('scheme:', uv.scheme)
# print('netloc:', uv.netloc)
# print('path:', uv.path)
# print('params:', uv.params)
# print('query:', uv.query)
# print('fragment', uv.fragment)
#
# uv2 = up.urlunparse(uv)
# print(uv2)

str = 'name=123&name=abc&age=18&sex=1&age=1&height=190'

strf = up.parse_qs(str)
print(strf)
strf = up.parse_qsl(str)
print(strf)

strpq = {'name': ['123', 'abc'], 'age': ['18', '1'], 'sex': ['1'], 'height': ['190']}
strpql = [('name', '123'), ('name', 'abc'), ('age', '18'), ('Sex ','. 1 '), (' Age ','. 1 '), (' height ',' 190 ')] 
print (up.quote (' boring day ape '))

# transcoding
#解码
print(up.unquote('%E6%97%A0%E8%81%8A%E7%8C%BF%E7%9A%84%E4%B8%80%E6%97%A5'))
print(up.urlencode(strpq))
print(up.unquote(up.urlencode(strpq)))
