Unicode Django URL 参数答案

【问题描述】：

我目前有这个 urlpattern：

from __future__ import unicode_literals
from django.confs.urls import url
from django.utils.encoding import python_2_unicode_compatible
from . import views

app_name = 'bans'
urlpatterns = [
    url(ur'^(?P<region>.*)/(?P<summoner_name>.*)/$', views.get_user, name='bans'),
]

但是，当 URL 包含像“å”这样的 utf-8 字符时，它会给我一个错误：

'ascii' codec can't encode character u'\xe5' in position 40: ordinal not in range(128)

为用户名 var 设置的值是：

u'k\xe5re%20j\xf8rgen'

上面应该说'kåre jørgen'。

这似乎与您的网址格式无关。回溯显示问题出在您视图的这一行：response = urllib2.urlopen('https://' + region + '.api.pvp.net/api/lol/' + region + '/v1.4/summoner/by-name/' + summoner_name_api + '?api_key=' + api_key.__str__())

【解决方案1】：

网址不能包含 Unicode 字符。浏览器应该对字符串进行百分比转义，并将其作为 ascii 发送。如果您的正则表达式不是 unicode 字符串，事情应该可以工作，但是当您获取 name 变量时，您必须对其进行百分比解码。
