我刚刚将 GAE 升级到 1.7.6（python 2.7）。我的应用在 URL 中使用了一些西班牙语字符（例如“españa”或“cádiz”等词）。到目前为止，我与他们打交道没有任何问题。但是，升级后，我总是在我的 url 中引入特殊字符时出现错误消息，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):

我编写了一个简单的应用程序来调试问题，但没有积极的结果：

#!/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，响应是预期的，并且浏览器显示 "hola" 词。但是，当访问“/españa”甚至“/espa%C3%B1a”时，开发服务器崩溃并出现上述错误。

请注意，该错误仅在开发中发生，我猜它与新的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！

有任何想法吗？请帮忙！

这似乎是开发服务器的一个错误。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。

如果更多的人“明星”它，希望他们能更快地解决这个问题。
