eBay Python 查找 API 中的身份验证错误

[英]authentication error in eBay Python Finding API

我正在尝试使用ebay.yaml文件将我的应用程序密钥(特别是我的应用程序 ID)快速传递到 Finding API。 但是,即使文件与程序在同一目录中,每次运行程序时它也会抛出此异常:

有谁知道如何阻止这种情况发生? ebay.yaml文件包含我所有不同 API 的所有应用程序密钥,包括令牌。 app-id 存在于文件中,这很奇怪,因为异常表明APPNAME在文件中存在时设置为None

作为参考,该程序以及ebay.yaml文件位于存储库ebay ,该存储库位于我最初从 GitHub 获得的ebaysdk-python存储库中。 ebaysdk-python存储在适用于 Windows 的 Ubuntu Linux shell 的系统根目录中。 我正在使用的程序:

#!/usr/bin/python3
from ebaysdk.finding import Connection as Finding
#import os
#import sys

api = Finding(domain = 'svcs.sandbox.ebay.com',  config_file = 'ebay.yaml', siteid = 'EBAY-US', debug = True)

request = {
    'keywords': 'buffalo nickel coin',
    'itemFilter': [
        {'name': 'condition', 'value': 'new'}
    ],
    'paginationInput': {
        'entriesPerPage': 10,
        'pageNumber': 1
    },
    'sortOrder': 'PricePlusShippingLowest'
}

response = api.execute('findItemsByKeywords', request)
results = open('/mnt/c/Users/iamno/Desktop/SearchResults.txt', 'w')
for item in response.reply.searchResult.item:
    results.write(item.title + "\n")
results.close()

如果我将config_file设置为None并显式地将我的 app-id 传递到appid参数中,则程序可以正常工作。 ebay.yaml只是没有被正确识别。

这是因为默认的 'ebay.yaml' 没有 sanbox 域(svcs.ebay.com 是 prod 域)

只需将其添加到 yaml 文件中

svcs.sandbox.ebay.com:
    appid: ENTER_YOUR_APPID_HERE

以下对我有用:

from ebaysdk.finding import Connection as Finding

yaml_path='C:/Users/Public/ebay/eBay_API/ebay_1.yaml' #path: yaml file location
api = Finding(config_file=yaml_path, siteid='EBAY-US')
request = {
    'keywords': 'buffalo nickel coin',
    'itemFilter': [
        {'name': 'condition', 'value': 'new'}
    ],
    'paginationInput': {
        'entriesPerPage': 10,
        'pageNumber': 1
    },
    'sortOrder': 'PricePlusShippingLowest'
}
response = api.execute('findItemsByKeywords', request)
print(response.reply.paginationOutput)

// {'pageNumber': '1', 'entriesPerPage': '10', 'totalPages': '982', 'totalEntries': '9813'}
