Flask-Restful中的abort方法忽略CORS选项

我有一个配置了一些CORS选项的Flask-Restful API:

api = Api()
api.decorators=[cors.crossdomain(origin='*', headers=['accept', 'Content-Type'])]

...

api.init_app(app)

POST如果请求中的数据无效,我的API接受可能失败的请求:

class myAPI(Resource):
    def post(self):
        args = request.get_json()
        if args.get('something'):
            return {'message': 'Request worked, data received!',
                    'something': args['something']}
        else:
            abort(500, "Error: Data must contain a 'something' field!")

当我成功POST请求我的API时,我可以看到CORS选项已正确设置:

...
* upload completely sent off: 81 out of 81 bytes
* HTTP 1.0, assume close after body
< HTTP/1.0 200 OK
< Content-Type: application/json
< Content-Length: 205
< Access-Control-Allow-Origin: *
< Access-Control-Allow-Methods: HEAD, GET, POST, OPTIONS
< Access-Control-Max-Age: 21600
< Access-Control-Allow-Headers: ACCEPT, CONTENT-TYPE
< Server: Werkzeug/0.9.4 Python/2.7.6

但是,如果我的类中的post调用通过abort方法退出(通过故意将错误数据发送到请求),那么Access-Control-*响应中的所有字段都会丢失:

* upload completely sent off: 75 out of 75 bytes
* HTTP 1.0, assume close after body
< HTTP/1.0 500 INTERNAL SERVER ERROR
< Content-Type: application/json
< Content-Length: 51
< Server: Werkzeug/0.9.4 Python/2.7.6

是否可以使该abort方法与我的CORS规则一致,或者我应该创建自己的完整响应并避免使用中止函数？
