一、问题描述:
请求方式:POST
报错提示:
AttributeError: 'NoneType' object has no attribute 'get'
二、问题分析:
根据报错提示分析:空类型对象那个没有"get"属性。
代码中打印 request.get_json() 函数的值,打印结果为None
可以判断问题就出在 request.get_json() 函数上。查看源代码:
# 源代码
def get_json(self, force=False, silent=False, cache=True):
"""Parse :attr:`data` as JSON.
If the mimetype does not indicate JSON
(:mimetype:`application/json`, see :meth:`is_json`), this
returns ``None``.
If parsing fails, :meth:`on_json_loading_failed` is called and
its return value is used as the return value.
:param force: Ignore the mimetype and always try to parse JSON.
:param silent: Silence parsing errors and return ``None``
instead.
:param cache: Store the parsed JSON to return for subsequent
calls.
"""
三、解决方法:
1.http 请求增加header: Content-Type:application/json ;
2.使用 request.get_json(force=True) 忽略mimetype。
