Question

在用Flask-Restful实现REST API时，我想返回Flask的 Response 对象，因为它灵活且易于使用。例如：

return Response(
            response=jsonify({
                "data": {
                    "import_id": import_id
                }
            }),
            status=201,
            mimetype="application/json"
        )

但是看上去烧瓶躁动不支持这种事情：

2019-08-05 08:52:30,077 werkzeug     INFO     172.21.0.1 - - [05/Aug/2019 08:52:30] "POST /imports HTTP/1.1" 500 -
2019-08-05 08:52:30,078 werkzeug     ERROR    Error on request:
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/werkzeug/serving.py", line 303, in run_wsgi
    execute(self.server.app)
  File "/usr/local/lib/python3.7/site-packages/werkzeug/serving.py", line 293, in execute
    for data in application_iter:
  File "/usr/local/lib/python3.7/site-packages/werkzeug/wsgi.py", line 507, in __next__
    return self._next()
  File "/usr/local/lib/python3.7/site-packages/werkzeug/wrappers/base_response.py", line 45, in _iter_encoded
    for item in iterable:
TypeError: 'Response' object is not iterable

是否有任何解决方法可以使用Response？如果没有，我该如何返回 flask-restfull 的模仿类型？

jsonify()函数返回一个flask.Response()对象，而json.dumps(obj)将obj序列化为JSON格式的字符串。


....
from Flask import json, Response

....
   return Response(
        response=json.dumps({
            "data": {
                "import_id": import_id
            }
        }),
        status=201,
        mimetype="application/json"
    )

烧瓶是否可以返回Response对象？
