pythonurlparseDetailed explanation

The following editor will bring you a summary of how to use python (urlparse) templates. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

1. Introduction

urlparse module users parse the url into 6 components and use tuples Return in the form, the six parts returned are: scheme (protocol), netloc (network location), path (path), params (path segment parameters), query (query), fragment (fragment).

2. Function enumeration

1. urlparse.urlparse()(Parse url into components, url must be Starting with http://)


>>> urlparse.urlparse("https://i.cnblogs.com/EditPosts.aspx?opt=1")
ParseResult(scheme='https', netloc='i.cnblogs.com', path='/EditPosts.aspx', params='', query='opt=1', fragment='')

The returned element will also contain other attributes, such as (username, password, hostname, port):


>>> urlparse.urlparse("https://i.cnblogs.com:80/EditPosts.aspx?opt=1").port
80


>>> urlparse.urlparse("https://i.cnblogs.com:80/EditPosts.aspx?opt=1").hostname
'i.cnblogs.com'

2. urlparse.urljoin() (Combines relative addresses into a url. There is no limit on input. The beginning must be Is http://, otherwise the front will not be combined)


>>> urlparse.urljoin("https://i.cnblogs.com","EditPosts.aspx")
'https://i.cnblogs.com/EditPosts.aspx'

3. urlparse.urlsplit(): Returns a tuple of 5 elements , suitable for URLs that follow RFC2396


##

>>> urlparse.urlsplit("https://i.cnblogs.com:80/EditPosts.aspx?opt=1")
SplitResult(scheme='https', netloc='i.cnblogs.com:80', path='/EditPosts.aspx', query='opt=1', fragment='')

4. urlparse.urlunsplit(): Use the urlsplit format to combine into a url, and the passed elements must is 5, or directly reassemble the decomposed tuples


>>> urlparse.urlunsplit(("https","i.cnblogs.com","EditPosts.aspx","a=a","b=b"))
'https://i.cnblogs.com/EditPosts.aspx?a=a#b=b'


>>> parse = urlparse.urlsplit("https://i.cnblogs.com:80/EditPosts.aspx?opt=1")
>>> urlparse.urlunsplit(parse)
'https://i.cnblogs.com:80/EditPosts.aspx?opt=1'

5, urlparse.urlunparse(): Use the format of urlparse to combine into a url, you can directly pass the return combination of urlparse


>>> parse = urlparse.urlparse("https://i.cnblogs.com:80/EditPosts.aspx?opt=1")
>>> urlparse.urlunparse(parse)
'https://i.cnblogs.com:80/EditPosts.aspx?opt=1'


>>> urlparse.urlunparse(("https","i.cnblogs.com","/EditPosts.aspx","","opt=1",""))
'https://i.cnblogs.com/EditPosts.aspx?opt=1'
