文档说要使用，request.get_json()但这会导致服务返回错误：

Server returned HTTP response code: 500

但是，呼叫request.data或request.json两者都起作用。

堆栈跟踪：

Traceback (most recent call last):

我认为 get_json 是获取 json 数据的首选方式。

在 Flask/wrappers.py 中，方法get_json()被定义为类的方法Request。

但是，同一个文件仍然包含旧的、已弃用的方法json()。如果您有旧版本的烧瓶，那么 a) 更新或 b)request.json()改用。

我对烧瓶响应对象有类似的错误，它最终成为版本问题，我们使用烧瓶 0.12.1 并且 get_json() 在 1.0.2 上可用

文件：

http://flask.pocoo.org/docs/0.12/api/#response-objects

VS

http://flask.pocoo.org/docs/1.0/api/#response-objects
