这是一个非常简单的问题.你还没有定义get_post_param.
你在哪里得到这个get_post_param想法？

只需定义一个名为get_post_param修复它的函数..

这是一个python shell会话

>>> get_post_param(request, 'userName')
NameError: not defined

>>> def get_post_param(request, param):
...    return request.POST.get(param) 
       # or scrap the idea of a function to do a one liner op anyways

>>> get_post_param(request, 'userName'):
'my_username'
