如何在 Python 3中进行 URL 编码？

我曾经尝试跟随文件，但是在 Python 3中无法使用 urlparse.parse.quote_plus():

from urllib.parse import urlparse


params = urlparse.parse.quote_plus({'username': 'administrator', 'password': 'xyz'})

我明白

AttributeError: “ function”对象没有“ parse”属性

You misread the documentation. You need to do two things:

Quote each key and value from your dictionary, and
Encode those into a URL

Luckily urllib.parse.urlencode does both those things in a single step, and that's the function you should be using.

from urllib.parse import urlencode, quote_plus


payload = {'username':'administrator', 'password':'xyz'}
result = urlencode(payload, quote_via=quote_plus)
# 'password=xyz&username=administrator'

You’re looking for urllib.parse.urlencode

import urllib.parse


params = {'username': 'administrator', 'password': 'xyz'}
encoded = urllib.parse.urlencode(params)
# Returns: 'username=administrator&password=xyz'

For Python 3 you could try using quote instead of quote_plus:

import urllib.parse


print(urllib.parse.quote("http://www.sample.com/", safe=""))

Result:

http%3A%2F%2Fwww.sample.com%2F

Or:

from requests.utils import requote_uri
requote_uri("http://www.sample.com/?id=123 abc")

Result:

'https://www.sample.com/?id=123%20abc'
