烧瓶仅宁静输出XML

如何解决烧瓶仅宁静输出XML

我刚开始尝试创建API，我很想制作一个仅在API发布请求后才返回XML格式数据的应用。

下面的烧瓶相关代码只是如何制作XML response from the git repo示例以进行查看的美化版本。

from simplexml import dumps
from flask import make_response,Flask
from flask_restful import Api,Resource

def output_xml(data,code,headers=None):
    """Makes a Flask response with a XML encoded body"""
    resp = make_response(dumps({'response' :data}),code)
    resp.headers.extend(headers or {})
    return resp


tou = [{
    "startTime": "2:00PM","duration": "6 Hours","numberOfIntervals" : 3,"intervalDuration" : "1 hour,4 hour,1 hour","typicalIntervalValues" : "$0.50,$0.75,$0.50"
}]



app = Flask(__name__)
api = Api(app,default_mediatype='application/xml')
api.representations['application/xml'] = output_xml


class call(Resource):
    def post(self):
        callInfo = {"notification" : "True","startTime" : "2:00PM","duration" : "6 Hours","randomization": "None","rampup" : "None","recovery" : "None","numberOfSignals" : "2","signalNameSimple" : [{
                    "signalType" : "level","units" : "None","numberOfIntervals" : "None","intervalDuration" : "None","typicalIntervalValues" : "1,2,1","signalTarget" : "None"}],"signalNameElectricityPrice" : [{
                    "signalType" : "price","units" : "USD per kWh","numberOfIntervals" : "3",$0.50","signalTarget" : "None"}]
                        }
        return callInfo



api.add_resource(call,'/api/v1/cpp/scenario/three')


if __name__ == '__main__':
    app.run(debug=False)

我遇到的问题（也许这甚至不是问题）是Flask-restful应用程序仅在请求标头中定义了XML响应，否则返回JSON响应。例如，在下面的代码中，如果我没有headers={'Accept': 'application/xml'}，则此脚本将出错，因为Flask-restful应用程序响应为JSON格式。

import requests
import xml
from xml.etree import ElementTree


response = requests.post("http://127.0.0.1:5000/api/v1/cpp/scenario/three",headers={'Accept': 'application/xml'})
#response = requests.post("http://127.0.0.1:5000/api/v1/cpp/scenario/three")


root = ElementTree.fromstring(response.content)
for child in root.iter('*'):
    print(child.tag)

问题，如何修改仅返回XML的Flask App？如果这是一个愚蠢的问题，有人可以详细说明吗API为什么需要JSON和XML？我希望学习如何仅使用XML来实现的现实场景，并且我担心拥有多余的headers={'Accept': 'application/xml'}会造成问题，因为与API通信的设备只是“机器”，而不是人具有自定义的python编码功能。如果有人可以帮助我了解API行业的典型特征，那也可能会有所帮助：）
