google-app-engine - GAE : How to use unicode characters in url

Question

我刚刚将 GAE 升级到 1.7.6(python 2.7)。我的应用程序在 URL 中使用了一些西类牙字符(例如“españa”或“cádiz”等词)。到目前为止，我对付他们没有任何问题。但是，升级后，每当我在我的 url 中引入特殊字符时，我都会收到错误消息并且我的应用程序崩溃:

ProgrammingError('You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.',)
Traceback (most recent call last):

我已经编写了一个简单的应用程序来调试问题，但没有得到积极的结果:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import webapp2

class MainHandler(webapp2.RequestHandler):
    def get(self):
        self.response.write('Hello world!')

class MyHandler(webapp2.RequestHandler):
  def get(self, param):
    self.response.write(param)

app = webapp2.WSGIApplication([
    ('/', MainHandler),
    ('/(.*)', MyHandler)
], debug=True)

当访问 URL“/hola”时，响应符合预期，浏览器显示“hola”字样。但是，当访问“/españa”甚至“/espa%C3%B1a”时，开发服务器崩溃并出现上面显示的错误。

注意这个错误只出现在开发中，估计和新的sqlite数据库有关；但是，在前面的示例中，我根本没有使用数据库!

有什么想法吗？请帮忙!

这似乎是开发服务器的错误。现在最好的办法是在 GAE 错误跟踪器上为错误加注星标:GAE bug - url's with unicode characters .

如果有更多人“加注星标”，希望他们能更快地解决这个问题。
