应用在本地运行正常但在appspot上不行

Question

我正在让用户通过Foursquare在我的网页上进行身份验证，当他们被重定向回我的网页时，我会从网址中提取返回的信息。在本地测试时一切正常，但当我部署到线上时，出现了以下错误

    Traceback (most recent call last):

TemplateSyntaxError: Unclosed tags: endblock, endblock bodycontent

更新

在我的代码中，似乎导致问题的那一行是我尝试执行 doRender(self, '500.html') 时。这是 doRender 方法

def doRender(handler, tname, values = { }):    
    template_values = dict(values) 
    handler.session = Session()
    if 'access_token' in handler.session: 
        template_values['access_token'] = handler.session['access_token'] 
    path = os.path.join(os.path.dirname(__file__), tname)
    handler.response.out.write(template.render(path, template_values))

而模板如下

{% extends "index.html" %} 
{% block bodycontent %}
Server Error
      <p>
      There has been an error
      </p>
{% endblock %}

Answer 1

TemplateSyntaxError: Unclosed tags: endblock, endblock bodycontent

{% endblock %}

这段话告诉你至少有一个问题出现在了哪里。你需要关闭这个 endblock：

Answer 2

你在你的app.yaml文件里设置了'/_ah/login_required'这个处理程序吗？

我假设你已经开启了联邦登录，这样才能使用Foursquare的账号。如果是这样的话，你需要定义一个自己的登录处理程序，这样它才能在appspot上正常工作（本地测试用localhost的登录处理方式是不同的）。

例如：

handlers:
- url: /_ah/login_required
  script: do_openid_login.py
