Django - Url模式正则表达式不匹配字符串参数与重音符 [英] Django - Url pattern regex not matching string parameter with accents

问题描述

我在Django应用程序中传递带有重音符的字符串参数的麻烦。我有以下url模式：

  url（r'^ galeria /（？P< page> \d +）/（ ？P< order> \w +）/（？P< query> [\w | \W] +）'，'possible_brastemp.views.gallery_with_page_and_query'），
  / pre> 
 
 
当我尝试像
  http： //127.0.0.1:8000/galeria/1/ultimos/Julian%20Andr%E9s 
  
图案不匹配我已将问题分离到'％E9'字符（'％20'不会打破匹配）。
 
 
 
如何更改正则表达式以匹配参数编码字符？
 
 
 
谢谢
解决方案
使用％c3％a9 而不是URL中的％e9 。正则表达式没有失败... Django甚至没有访问urlconf。检查日志，你可能会收到400个错误。
 
 
 
 URI路径只能包含UTF-8编码的字符。任何无法表示为正常可打印的ASCII字符（并且不在保留列表中）的UTF-8字符都应进行百分比编码。
 
 
 
 é（U + 00E9）是UTF-8中的多字节字符： 0xc3a9 。百分比编码的形式将是％C3％A9 。单字节0xe9不是有效的UTF-8字符。
 
 
 
请参阅 RFC 3986 。
 
 
 
  [\w | \W] + 成功匹配包含％C3％A9 的网址。 Django似乎将URL字节字符串解码为Unicode字符串，然后将其转换为UTF-8以进行urlconf匹配。
 
I'm having some trouble passing string arguments with accents to my Django application. I have the following url pattern:
url(r'^galeria/(?P<page>\d+)/(?P<order>\w+)/(?P<query>[\w|\W]+)', 'possible_brastemp.views.gallery_with_page_and_query'),
When I try a url like: 
 http://127.0.0.1:8000/galeria/1/ultimos/Julian%20Andr%E9s
the pattern is not matched. I have isolated the problem to the '%E9' character (the '%20' doesn't break the match).

How can I change the regex to match parameters with encoded characters?

Thank you
解决方案
Use %c3%a9 instead of %e9 in the URL. The regex isn't failing... Django isn't even getting to the urlconf. Check the logs, you're probably getting 400 errors.

URI paths should contain UTF-8-encoded characters only. Any UTF-8 character that cannot be represented as a normal, printable ASCII character (and is not on the reserved list) should be percent-encoded.

é (U+00E9) is a multibyte character in UTF-8: 0xc3a9. The percent-encoded form would be %C3%A9. The single byte 0xe9 is NOT a valid UTF-8 character.

See RFC 3986.

[\w|\W]+ successfully matches URLs containing %C3%A9. Django appears to percent-decode the URL byte string into a Unicode string, then converts it to UTF-8 for urlconf matching.
