urllib库parse模块用法总结如下:

from urllib import parse

url = 'https://www,baidu.com/s?wq=python&username=asd#1'
#方法一，有params
#res = parse.urlparse(url)
#方法二，无params
res = parse.urlsplit(url)
print(res)
print('scheme:',res.scheme)
print('netloc:',res.netloc)
print('path:',res.path)
#print('params:',res.params)
print('query:',res.query)
print('fragment:',res.fragment)

# !/usr/bin/env python
# -*- coding:utf-8 -*-
 
"""
urllib.parse
    处理URL的模块
"""
 
import urllib.parse
 
# 解析url，返回包含url信息的6元元组
res=urllib.parse.urlparse("https://docs.python.org/3/library/urllib.parse.html#module-urllib.parse")
print(res)
print(res.scheme)
print(res.netloc)
print(res.path)
print(res.params)
print(res.query)
print(res.fragment)
 
# 从任意包含6元素的可迭代数据结构中构造url字符串并返回
url=urllib.parse.urlunparse(["http","www.baidu.com","index","","",""])
print(url)
 
# 分割url，返回包含url的元组，可用来替代urlparse()
res=urllib.parse.urlsplit("https://docs.python.org/3/library/urllib.parse.html#module-urllib.parse",scheme="https",allow_fragments=True)
print(res)
# 从SplitResult中获取url字符串
print(res.geturl())
 
# 从任意包含5元素的可迭代数据结构中构造url字符串并返回，可用来替代urlunparse()
url=urllib.parse.urlunsplit(["http","x.org","index.html","",""])
print(url)
 
# 从2个url中构造完整的url
url=urllib.parse.urljoin(base="http://www.baidu.com",url="index.html#a",allow_fragments=True)
print(url)
url=urllib.parse.urljoin(base="http://www.baidu.com/",url="//www.baidu.com/index.html")
print(url)
 
# 对含有特殊符号的URL进行编码，使其转换为合法的url字符串
url=urllib.parse.quote("https://www.baidu.com/s?wd=编程 python",safe="/")
print(url)
# 效果与quote()唯一不同的是，将空格转换为加号 +
url=urllib.parse.quote_plus("https://www.baidu.com/s?wd=编程 python",safe="/")
print(url)
# 与quote()相反
url=urllib.parse.unquote("https%3A//www.baidu.com/s%3Fwd%3D%E7%BC%96%E7%A8%8B%20python")
print(url)
# 与quote_plus()相反
url=urllib.parse.unquote_plus("https%3A//www.baidu.com/s%3Fwd%3D%E7%BC%96%E7%A8%8B+python")
print(url)
 
# url编码,第一个参数为dict，常用来处理url参数
params={"key1":"编程","key2":"写作"}
params=urllib.parse.urlencode(params)
print(params)
# url解码，返回字典，与urlencode()相反
params=urllib.parse.parse_qs(urllib.parse.urlencode({"key":"编程"}))
print(params)
# 与parse_qs()唯一的不同是返回列表
params=urllib.parse.parse_qsl(urllib.parse.urlencode({"key1":"编程"}))
print(params)
