原标题:How to JSON encode Entities?

开始使用谷歌应用发动机。 我想像Twitter一样谈一下AJAX。

class ChatMessage(db.Model):
  message = db.StringProperty()
  created = db.DateTimeProperty(auto_now=True)

页: 1

class RPCHandler(webapp.RequestHandler):
  def get(self):
    chat_list = { message : Hello! }
    self.response.out.write(simplejson.dumps(chat_list))

成果:

这是科索沃。 但取代RPCHandler

class RPCHandler(webapp.RequestHandler):
  def get(self):
    newchat = ChatMessage(message="Hi!")
    newchat.put()
    que = db.Query(ChatMessage).order( -created )
    chat_list = que.fetch(limit=1)

    self.response.out.write(simplejson.dumps(chat_list))

Result: Error. The server is not accessible (get)

How can I JSON encode Entities?

最佳回答
问题回答

I use gson for GAE/J. 你可以给它一个物体(或就你而言,从结果中提取 st子),并获得一名JSON的扼杀。

核对发动机的误差。 它将告诉你它正在经历哪些错误。 或许,你试图打上一条不熟悉的灰色。 JSON将只做像名单和字典这样的简单 st。 您可以将其用于复杂的习俗类型。
