Urlunparse ()

# urlunparse () length must be 6 parameters, or it will throw a problem  with insufficient or excessive number of parameters data = ['http','www.baidu.com','index.html  ','user','a=6',' Comment ' ]  print

Urlsplit ()

#the Urlsplit () and Urlparse () methods are similar and no longer parse the params parameterresult = Urlsplit ('http://www.baidu.com/index.html;user?id=5#comment')  Print(Result)#The returned result is also a tuple, which can be obtained by index, or it can be obtained by using the property name.#Splitresult Property Scheme (://Protocol), Netloc (/domain), path (access path), query (query condition), fragment (# anchor)result = Urlparse ('http://www.baidu.com/index.html;user?id=5#comment', allow_fragments=False)Print(Result.scheme,result[0])

Urlunsplit ()

# the Urlunsplit () and Urlunparse () methods are similar, except that the length becomes  5 parameters data = ['http','www.baidu.com','index.html  ','a=6','comment']   Print

Urljoin ()

#Urljoin () is also a way of merging links, compared to the previous two methods, without the length of the specified Parameter object before the specific#the Urljoin () method provides two parameters, Base_url (the underlying link) as the first argument, and the new link as the second parameter, which parses the Base_url Scheme,netloc and path#these three content and supplement the true part of the new link, and finally return the resultPrint(Urljoin ('http://www.baidu.com','https://cuiqingcai.com/FAQ.html'))  Print(Urljoin ('http://www.baidu.com/about.html','https://cuiqingcai.com/FAQ.html'))  Print(Urljoin ('http://www.baidu.com','faq.html'))  Print(Urljoin ('http://www.baidu.com/about.html','https://cuiqingcai.com/FAQ.html?question=2'))  Print(Urljoin ('HTTP://WWW.BAIDU.COM?WD=ABC','https://cuiqingcai.com/index.php'))  Print(Urljoin ('http://www.baidu.com','? category=2#comment'))  Print(Urljoin ('www.baidu.com','? category=2#comment'))  Print(Urljoin ('www.baidu.com#comment','? category=2'))

UrlEncode ()

# UrlEncode () serialization dictionary type conversion to request type   params = {      'name''germey',      '  Age ' :  ' http://www.baidu.com? '   '  url = base_url + urlencode (params)  print(URL)  

Parse_qs ()

# Parse_qs () deserialization reverses the request parameter back to the dictionary  parameter  from Import Parse_qs    ' name=germey&age=22 '  params = Parse_qs (query)  print(params)  

PARSE_QS1 ()

# parse_qs1 () It is used   to convert the parameters into a list of tuples  from Import PARSE_QSL    ' name=germey&age=22 '  params = PARSE_QSL (query)  Print

QUOTE ()

# quote () This method can be converted to URL-encoded format, URL with Chinese parameters, it is also possible to cause garbled problems, in this way can be converted to a URL code    from Import Quote     ' Wallpapers '    ' http://www.baidu.coms?wd= ' + quote (keyword)    Print (URL)  

Unquote ()

# unquote () it corresponds to the above method and can be URL  decoded  from Import unquote    ' http://www.baidu.coms?wd=%E5%A3%81%E7%BA%B8 '  Print (unquote (URL))
