RuntimeError: You called this URL via POST, but the URL doesn’t end in a slash and you have APPEND_SLASH set.

做公众号测试的时候，发现了个问题:

提交表单报错:RuntimeError: You called this URL via POST, but the URL doesn’t end in a slash and you have APPEND_SLASH set.

解决方案：

提示form的action地址最后不是/结尾的，而且APPEND_SLASH的值是Ture

将from的action地址改为 / 结尾的就可以了 （http:://127.0.0.1:12345/weixin/）
或者 
修改settings:APPEND_SLASH=False
