ebayapi没有从GetCategories Call

Question

我期望它返回类别和子类别的列表，但是我得到的输出与之完全不同。

脚本：

import json
import datetime
import ebaysdk

from ebaysdk.trading import Connection as Trading

def getUser():

    api = Trading(config_file='ebay.yaml')

    f = open('json_cat_output.txt','w')
    api.execute('GetCategories', {'CategorySiteID': 0},{'DetailLevel': "ReturnAll"})
    dictstr = api.response.dict()
    print dictstr
    dump_file = json.dumps(dictstr, indent=4, default=str)
    f.write(dump_file)
    f.close()

if __name__ == "__main__":

    getUser()

脚本执行的输出：

{
    "UpdateTime": "2018-04-10T02:31:49.000Z", 
    "Version": "1057", 
    "Ack": "Success", 
    "Timestamp": "2018-07-09T18:41:48.391Z", 
    "MinimumReservePrice": "0.0", 
    "ReservePriceAllowed": "true", 
    "CategoryVersion": "118", 
    "Build": "E1057_CORE_APICATALOG_18691267_R1"
