http://docs.python.org/2/library/urlparse.html?highlight=urlparse#urlparse

 

主要函數如下：

1。urlparse

 

#!/usr/bin/python
import urlparse
webURL = "http://www.google.com/search?hl=en&q=python&btnG=Google+Search"
#parseTuple = urlparse.urlsplit(webURL)
parseTuple = urlparse.urlparse(webURL)
print parseTuple

輸出如下：

 

ParseResult(scheme='http', netloc='www.google.com', path='/search', params='', query='hl=en&q=python&btnG=Google+Search', fragment='')

我們可以看到輸入爲6個部分；元組 (scheme, netloc, path, parameters, query, fragment)

2. urlparse.urlunparse(parts)

 

#!/usr/bin/python
import urlparse
URLschema = "ftp"
webURL = "http://www.google.com/search?hl=en&q=python&btnG=Google+Search"
#parseTuple = urlparse.urlsplit(webURL)
parseTuple = urlparse.urlparse(webURL)
print parseTuple
u = urlparse.urlunparse((URLschema,parseTuple.netloc,parseTuple.path,parseTuple.params,parseTuple.query,''))
print u

結果如下：

重新拼合成了一個新的url

 

ParseResult(scheme='http', netloc='www.google.com', path='/search', params='', query='hl=en&q=python&btnG=Google+Search', fragment='')
ftp://www.google.com/search?hl=en&q=python&btnG=Google+Search

3.

urlparse.urlsplit(urlstring[, scheme[, allow_fragments]])

This function returns a 5-tuple: (addressing scheme, network location, path, query, fragment identifier).

SplitResult(scheme='http', netloc='www.google.com', path='/search', query='hl=en&q=python&btnG=Google+Search', fragment='')

4.urlparse.urljoin(base, url[, allow_fragments])

這個的主要作用是拼接url

 

import urlparse
#-*- coding:utf-8 -*-
#測試1
base_url = "http://motor.blog.51cto.com/blog/addblog.php"
relative_url = "../blog/test.php"
abs_url = urlparse.urljoin(base_url, relative_url)
print abs_url
#測試2
base_url_2 = "http://motor.blog.51cto.com/blog/addblog.php"
relative_url_2 = "test.php"
abs_url_2 = urlparse.urljoin(base_url_2, relative_url_2)
print abs_url_2
#測試3
base_url_3 = "http://motor.blog.51cto.com/blog/"
relative_url_3 = "test.php"
abs_url_3 = urlparse.urljoin(base_url_3, relative_url_3)
print abs_url_3
#測試4
base_url_4 = "http://motor.blog.51cto.com/blog"
relative_url_4 = "test.php"
abs_url_4 = urlparse.urljoin(base_url_4, relative_url_4)
print abs_url_4

結果如下：
