ebay feed 批量修改库存的代码

以下是一个示例代码，可以批量修改 eBay Feed 中的库存信息：

import requests
import xml.etree.ElementTree as ET

# eBay API endpoint and credentials
endpoint = 'https://api.ebay.com/ws/api.dll'
dev_id = 'YOUR_DEV_ID'
app_id = 'YOUR_APP_ID'
cert_id = 'YOUR_CERT_ID'
auth_token = 'YOUR_AUTH_TOKEN'
site_id = '0' # US site ID

# function to build eBay API request body
def build_request_body(item_id, quantity):
    xml = '<?xml version="1.0" encoding="UTF-8"?>'
    xml += '<BulkDataExchangeRequests xmlns="urn:ebay:apis:eBLBaseComponents">'
    xml += '<Header><SiteID>{}</SiteID></Header>'.format(site_id)
    xml += '<Request><RequestID>1</RequestID>'
    xml += '<Item><ItemID>{}</ItemID>'.format(item_id)
    xml += '<Quantity>{}</Quantity></Item></Request>'.format(quantity)
    xml += '</BulkDataExchangeRequests>'
    return xml

# function to make eBay API call
def call_ebay_api(xml_request):
    headers = {
        'X-EBAY-API-COMPATIBILITY-LEVEL': '967',
        'X-EBAY-API-DEV-NAME': dev_id,
        'X-EBAY-API-APP-NAME': app_id,
        'X-EBAY-API-CERT-NAME': cert_id,
        'X-EBAY-API-CALL-NAME': 'BulkDataExchange',
        'X-EBAY-API-SITEID': site_id,
        'X-EBAY-API-IAF-TOKEN': auth_token,
        'Content-Type': 'text/xml'
    }
    response = requests.post(endpoint, headers=headers, data=xml_request)
    return response

# example usage
item_ids = ['ITEM_ID_1', 'ITEM_ID_2', 'ITEM_ID_3']
quantities = [10, 20, 30]

for item_id, quantity in zip(item_ids, quantities):
    xml_request = build_request_body(item_id, quantity)
    response = call_ebay_api(xml_request)
    root = ET.fromstring(response.content)
    ack = root.find('.//{urn:ebay:apis:eBLBaseComponents}Ack').text
    if ack == 'Success':
        print('Successfully updated quantity for item {}'.format(item_id))
    else:
        print('Failed to update quantity for item {}: {}'.format(item_id, response.content))

请注意，在使用此代码之前，您需要将代码中的 `YOUR_DEV_ID`、`YOUR_APP_ID`、`YOUR_CERT_ID` 和 `YOUR_AUTH_TOKEN` 替换为您自己的 eBay 开发者凭据。此外，您还需要将 `ITEM_ID_1`、`ITEM_ID_2` 和 `ITEM_ID_3` 替换为您要更新库存信息的 eBay 商品的实际 ID，以及 `10`、`20` 和 `30` 替换为相应的库存数量。
