I can't really work out what's going on in all that unformatted, unindented text. I'm also not clear on what your question is. Could you narrow it down and reduce the amount of code?

Staff glenn | 9718 posts | PythonAnywhere staff | March 17, 2015, 1:58 p.m. | permalink

how to format?

deleted-user-678757 | 21 posts | March 18, 2015, 1:29 a.m. | permalink

先选择你的code 然后按一下 101010 那个键就可以 format 啦

Staff conrad | 4232 posts | PythonAnywhere staff | March 18, 2015, 11:34 a.m. | permalink

你能说一下你具体遇到了什么问题吗？

Staff conrad | 4232 posts | PythonAnywhere staff | March 18, 2015, 11:35 a.m. | permalink

Dear Admin: thank you for your formatting. Conrad,就是在view里导入utils里的类时用from utils import *时会提示标题的错误.但是不影响使用。 其实我是在程序中发现了一个bug想要解决.才一步一步的查到这里,今天突然发现那个错误不是这里导致的。就在你刚回复的另一个帖子里,我发现了调用微信接口的这套程序在添加自定义菜单时总是不成功,查看log发现是500错.可是看不到详细信息,所以只能发贴求助,希望你能帮帮我,by the way,加了你qq可是没有回音,不知道还有其它联系方式吗？很对问题需要请教。为盼。

deleted-user-678757 | 21 posts | March 18, 2015, 12:49 p.m. | permalink

这有可能是因为我们会限制免费用户的 WebApp 对外的沟通。这是因为不这样做的话常常会有人通过我们来发垃圾邮件或者DoS等恶性行为。如果你需要连接微信的 API 的话，我们可以把微信 API 的特定 url 加到我们的免费用户 whitelist 里。

还有，我应该刚在qq加了你。

Staff conrad | 4232 posts | PythonAnywhere staff | March 18, 2015, 6:52 p.m. | permalink

我认为不是服务器的问题，因为这个程序在本地测试点击修改菜单也没有反应，可是其他的功能如自动回复可以用，所以觉得不是API的问题，也许是程序哪里没有调试通

群里有人说是一个缓存token的表的问题，用memcached能搞定，不知道pythonanywhere支不支持memcached

deleted-user-678757 | 21 posts | March 19, 2015, 2:04 a.m. | permalink

我想应该不是这个问题，因为我们不会为你的 token 做任何的缓存。这纯碎是一个 django 的问题。我们继续在 qq 聊

Staff conrad | 4232 posts | PythonAnywhere staff | March 24, 2015, 12:33 p.m. | permalink

thank you for your help, QQchat
