urlencode encoding

Functionurlencode will not change the original encoding of the incoming parameters, which means that the encoding of the post or get parameters needs to be adjusted before calling.

Question: Now simulate requests to Google and Baidu. Since Baidu uses gb2312 encoding and Google uses utf8 encoding, the urlencode values ​​of the Chinese parameters submitted to the URL by the two sites are different. The following is " PythonTab Chinese Network" for example:

# coding: UTF-8
str = u'PythonTab中文网'
str = str.encode('gb2312')
d = {'name':str}
q = urllib.urlencode(d)
print q

Result:

name=PythonTab%D6%D0%CE%C4%CD%F8

Note: The parameter of urlencode must be Dictionary

Other usage

djangoThe urlencode is similar, the method is as follows:

from django.utils.http import urlquote
a = urlquote('PythonTab中文网')
print a

>>> import urllib
>>> a = "PythonTab中文网"
>>> a
'PythonTab\xe4\xb8\xad\xe6\x96\x87\xe7\xbd\x91'
