我可以在終端中查看響應內容，但在招搖的 UI 中，它顯示為空。問題：為了調試，我嘗試從ret函數中的變量打印值json_response_from_dict(dict_)，它向我顯示了我通過 swagger UI 輸入的值。但是在 Swagger UI 的響應中，它是空的。但是在終端中的響應中，它顯示<Response 141 bytes [200 OK]>并且終端中 ret 的值也顯示{"rec_id": 464, "frame_id_prob": [[1, 0.1], [2, 0.1], [3, 0.1], [4, 0.1], [5, 0.6]], "comment": "these frames suit everyone", "mine_id": NaN}我無法弄清楚該值在哪里丟失。MCVE：from flask import Flask, Blueprint, request, Responsefrom flask_restplus import Resource, Api, fieldsfrom flask.views import MethodViewimport jsonimport numpy as npdef json_response_from_dict(dict_): """converts a python dictionary to a json string, and returns a HHTP response for a JSON string dict_ -- input python dictionary """ ret = json.dumps(dict_) print(ret) resp = Response(response=ret, status=200, mimetype="application/json") print(resp) return respapp = Flask(__name__)api_v1 = Blueprint('api', __name__, url_prefix='/api/1')api = Api(api_v1, version='1.0', title='my API', description='my API',)ns = api.namespace('my', description='my operations')myModel = api.model('my Model', { 'rec_id': fields.Integer(readOnly=True, description='Random Choice'), 'comment': fields.String(required=True, description='Comments'), 'mine_id' : fields.String(required=True, description='unique ECP ID')})# Register blueprint at URL# (URL must match the one given to factory function above)app.register_blueprint(api_v1)但同樣的問題仍然存在。

if request.is_json:
mine_id = request.json.get('mine_id', np.nan)
return {'rec_id': np.random.choice(1000),
'fun_id_prob': [[1, 0.1], [2, 0.1], [3, 0.1], [4, 0.1], [5, 0.6]],
'comment': 'these games suit everyone',
'mine_id': mine_id
}
在此簽名不匹配即fun_id_prob不在 API 簽名中，也由于某種原因在調用X-Fields時，它需要保持為空。
只需使用
@ns.route("/dev/get_rec_id", methods=["POST"])
@ns.param('mine_id', 'unique ECP ID')
class RecommendationService(Resource):
@ns.doc('path to generate a unique recommendationid, and to determine which frames predictions can be made for. Expected/optional input : JSON string as a https html data objects with keys: mine_id -- unique ECP ID. If this is not provided generic frames recommendations will be provided.')
@ns.marshal_list_with(myModel)
def post(self):
mine_id = np.nan
if request.is_json:
mine_id = request.json.get('mine_id', np.nan)
return {'rec_id': np.random.choice(1000),
'comment': 'these games suit everyone',
'mine_id': mine_id
}
或將列表添加到簽名中，它將起作用:)。
