Urllib using four--urlencode

Urllib.urlencode

Convert dictionary data to URL encoding

 #  -*-coding:cp936-*- import   urllib  params  = { " score   ' : 100, '  name   ' :  "  Crawler basics   ", "  comment   ": "   Very good   " }qs  = Urllib.urlencode (params)  print  (QS) 

After encoding, follow the parameters passed behind the URL:

Comment=very+good&score=100&name=%c5%c0%b3%e6%bb%f9%b4%a1

Reverse

In the Urlparse bag.

Urlparse.parse_qs Method--Return dictionary

 import   Urllib  import   Urlparseparams  = { "  Score   ": 100,"  name   ' :  "  Crawler basics   ", "  comment   ": "   Very good   " }qs  = Urllib.urlencode (params) dic  = Urlparse.parse_qs (QS)  print  (DIC) 

Operation Result:

{'comment': ['very good'score ' : [' ['] 'name': ['\xc5\xc0\xb3\ Xe6\xbb\xf9\xb4\xa1']}

To extract parameters for a URL:

# -*-coding:cp936-*- Import Urllib Import  'https://www.baidu.com/s?ie=utf-8&f=8&rsv_bp=0&rsv_idx=1&tn=baidu&wd =python%20%e5%8f%91%e9%80%81%e9%82%ae%e4%bb%b6&rsv_pq=8ddee8730003c015&rsv_t=fc02p4%2by% 2fpkzafftaqgcglcxpvpvojkm6zg7pgczzb%2fezaqkxhsuwrpphqs&rqlang=cn&rsv_enter=1&rsv_sug3=14&rsv_ sug1=10&rsv_sug7=101'= urlparse.urlparse (URL)print(Result)

Get result first using the Urlparse.urlparse (URL) method

Parseresult (scheme='https', netloc='www.baidu.com', path= ' / S ', params=', query='Ie=utf-8&f=8&rsv_bp=0&rsv_idx=1&tn=baidu &wd=python%20%e5%8f%91%e9%80%81%e9%82%ae%e4%bb%b6&rsv_pq=8ddee8730003c015&rsv_t=fc02p4%2by% 2fpkzafftaqgcglcxpvpvojkm6zg7pgczzb%2fezaqkxhsuwrpphqs&rqlang=cn&rsv_enter=1&rsv_sug3=14&rsv_ sug1=10&rsv_sug7=101', fragment=')

Extract from query parameter in result

Import Urllib Import  'https://www.baidu.com/s?ie=utf-8&f=8&rsv_bp=0&rsv_idx=1&tn=baidu&wd =python%20%e5%8f%91%e9%80%81%e9%82%ae%e4%bb%b6&rsv_pq=8ddee8730003c015&rsv_t=fc02p4%2by% 2fpkzafftaqgcglcxpvpvojkm6zg7pgczzb%2fezaqkxhsuwrpphqs&rqlang=cn&rsv_enter=1&rsv_sug3=14&rsv_ sug1=10&rsv_sug7=101'==  Urlparse.parse_qs (result.query  )print(DIC)
