Question

每当我点击users.create_login_url()创建的链接时，我都会收到错误（如下所示）。在部署时，该工作正常，但在本地不起作用。有什么问题？

以下是代码：

import random
import os

from google.appengine.api import users
from google.appengine.ext import webapp, db
from google.appengine.ext.webapp import util, template
from google.appengine.ext.webapp.util import run_wsgi_app


class MainHandler(webapp.RequestHandler):
    def get(self):
        url = users.create_login_url('/quote')
        link = '<a href="%s">Login</a>' % url
        self.response.out.write(link)

class QuoteHandler(webapp.RequestHandler):
    def get(self):
        self.response.out.write("Quote Handler!")

    def new(self):
        self.response.out.write("New quote")


def main():
    application = webapp.WSGIApplication([(r'/quote/(.*)',QuoteHandler),('/', MainHandler)],
                                         debug=True)
    util.run_wsgi_app(application)


if __name__ == '__main__':
    main()

这是它给我的错误：

EDIT SDK版本：1.3.8 Python：2.7

Answer 1

您使用的是Google App Engine is not supported here的Python 2.7（问题Python 2.5）您需要降级到{{3}}才能使其正常运行。

Answer 2

我通过注释掉以下内容在Fedora 14 w / Python 2.7上解决了这个问题：

# logging.debug('Executing CGI with env:\n%s', pprint.pformat(env))

位于2312

的dev_appserver.py的{{1}}行

这是堆栈跟踪，您可以在其中看到行google_appengine_sdk_dir/google/appengine/tools导致抛出异常：

注释掉一行似乎使一切正常，没有其他错误，我不必降级到Python 2.5。

Answer 3

我已经看到了这个问题 - 你在本地运行了错误版本的Python。

安装Python 2.5，这个问题应该消失 - 它确实适合我。
