Question

我刚刚将GAE升级到1.7.6（python 2.7）。我的应用程序在URL中使用了一些西班牙语字符（例如“españa”或“cádiz”）。到目前为止，我处理它们没有任何问题。但是，升级后，我记得有错误信息和我的应用程序崩溃，每当我在我的网址中引入特殊字符时：

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):

我写了一个简单的应用程序来调试问题，没有任何积极的结果：

#!/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)

访问网址“/ hola”时，响应符合预期，浏览器会显示“hola”字样。但是，当访问“/españa”或甚至“/ espa％C3％B1a”时，开发服务器崩溃并显示上面显示的错误。

请注意，错误只发生在开发中，我猜它与新的sqlite数据库有关;但是，在前面的例子中，我根本没有使用数据库！

有什么想法吗？请帮助！

它似乎是开发服务器的错误。现在最好的办法是在GAE错误跟踪器上标记错误：GAE bug - url's with unicode characters。

希望如果有更多人“加注”它，他们会更快地解决这个问题。
