Python--URL操作

目标URL：http://127.0.0.1:5000/oauth/authorize?redirect_uri=http://127.0.0.1:5000/callback/?skillId=18936&token=NzkzODU4MzM3QUZFSElORkRWUQ==&client_id=jwETJvFj1nkRYtVJrNZE7lS9&response_type=code&state=0.1354064097905866

URL中的元素：

通常意义上的URL
重定义URL：
通常意思上的URL的请求参数
重定义URL里面的请求参数

解析URL—urlparse

我使用的Python3.6，使用的是自带的库urllib，并使用里面的子模块parse。

代码语言：javascript复制

from urllib.parse import urlparse

url = "https://127.0.0.1/oauth/authorize" 
      "?redirect_uri=https://open.bot.tmall.com/oauth/callback?skillId=18936&token=NzkzODU4MzM3QUZFSElORkRWUQ==" 
      "&client_id=o92cvMIa5FzGbq4LpHJoaf2j" 
      "&response_type=code" 
      "&state=0.1354064097905866"

dest_str = urlparse(url)
print(dest_str)

打印出来：

ParseResult(scheme='https', netloc='127.0.0.1', path='/oauth/authorize', params='', query='redirect_uri=https://open.bot.tmall.com/oauth/callback?skillId=18936&token=NzkzODU4MzM3QUZFSElORkRWUQ==&client_id=o92cvMIa5FzGbq4LpHJoaf2j&response_type=code&state=0.1354064097905866', fragment='')

它会解析为：

scheme：https
netloc：127.0.0.1
path：/oauth/authorize
params：
query：redirect_uri=https://open.bot.tmall.com/oauth/callback?skillId=18936&token=NzkzODU4MzM3QUZFSElORkRWUQ==&client_id=o92cvMIa5FzGbq4LpHJoaf2j&response_type=code&state=0.1354064097905866
fragment:

解析query—使用parse_qs

代码语言：javascript复制

from urllib.parse import urlparse, parse_qs

url = "https://127.0.0.1/oauth/authorize" 
      "?redirect_uri=https://open.bot.tmall.com/oauth/callback?skillId=18936&token=NzkzODU4MzM3QUZFSElORkRWUQ==" 
      "&client_id=o92cvMIa5FzGbq4LpHJoaf2j" 
      "&response_type=code" 
      "&state=0.1354064097905866"

dest_str = urlparse(url)
print(parse_qs(dest_str.query))

打印出来：

代码语言：javascript复制

{'redirect_uri': ['https://open.bot.tmall.com/oauth/callback?skillId=18936&token=NzkzODU4MzM3QUZFSElORkRWUQ=='], 'client_id': ['o92cvMIa5FzGbq4LpHJoaf2j'], 'response_type': ['code'], 'state': ['0.1354064097905866']}

解析redirect_uri—使用urlparse

代码语言：javascript复制

from urllib.parse import urlparse, parse_qs

url = "https://127.0.0.1/oauth/authorize" 
      "?redirect_uri=https://open.bot.tmall.com/oauth/callback?skillId=18936&token=NzkzODU4MzM3QUZFSElORkRWUQ==" 
      "&client_id=o92cvMIa5FzGbq4LpHJoaf2j" 
      "&response_type=code" 
      "&state=0.1354064097905866"

dest_1 = urlparse(url)
dest_2 = parse_qs(dst_1.query)
dest_3 = urlparse(dest_2)
print(parse_qs(dest_str.query))
