Question

这个问题根本不是特定于python的，因为我知道无论使用什么SDK，都会进行所有相同的http api调用。

我有一堆列表（数百个），我需要以编程方式进行更改。需要的是改变项目的变化图片。使用ReviseItem api并没有像我预期的那样工作。

详细说明：

如果我对itemID 332121070278做了GetItem请求，我会收到以下回复：

<?xml version="1.0" encoding="UTF-8"?>
<GetItemResponse xmlns="urn:ebay:apis:eBLBaseComponents">

                </VariationSpecificPictureSet>
                <VariationSpecificPictureSet>
                    <VariationSpecificValue>Olive</VariationSpecificValue>
                    <PictureURL>https://s3-eu-west-1.amazonaws.com/images.linnlive.com/b3bb06dbe22847df07835760a144c5dd/881a11fe-bb73-4d3a-a556-cdecae2ee723.jpg</PictureURL>

                </VariationSpecificPictureSet>
                <VariationSpecificPictureSet>
                    <VariationSpecificValue>Nearly Black</VariationSpecificValue>
                    <PictureURL>https://s3-eu-west-1.amazonaws.com/images.linnlive.com/b3bb06dbe22847df07835760a144c5dd/211f43f9-a4fd-40fd-9712-743e5ab328d0.jpg</PictureURL>

                </VariationSpecificPictureSet>
                <VariationSpecificPictureSet>
                    <VariationSpecificValue>Wine</VariationSpecificValue>
                    <PictureURL>https://s3-eu-west-1.amazonaws.com/images.linnlive.com/b3bb06dbe22847df07835760a144c5dd/27f7768e-3987-4ff4-9440-614c0853b0cb.jpg</PictureURL>
                    <ExternalPictureURL>https://s3-eu-west-1.amazonaws.com/images.linnlive.com/b3bb06dbe22847df07835760a144c5dd/27f7768e-3987-4ff4-9440-614c0853b0cb.jpg</ExternalPictureURL>
                </VariationSpecificPictureSet>
            </Pictures>
        </Variations>
    </Item>
</GetItemResponse>

因此，为了在python SDK中提交我的ReviseItem请求，我执行了以下操作：

def reviseItem(opts):
    try:

        api = Trading(debug=opts.debug, config_file=opts.yaml, appid=opts.appid,
                      certid=opts.certid, devid=opts.devid, warnings=True, timeout=20, siteid='3')

        response = api.execute('ReviseItem', {'Item': {
            'ItemID': '332121070278',
            'Variations': {
                'Pictures': {
                    'VariationSpecificPictureSet': [
                        {
                            'PictureURL': 'https://cdn.shopify.com/s/files/1/0740/6535/products/wine_1_43df4936-4a20-4419-8643-40575a9bb457.jpg?v=1479773519',
                            'ExternalPictureURL': 'https://cdn.shopify.com/s/files/1/0740/6535/products/wine_1_43df4936-4a20-4419-8643-40575a9bb457.jpg?v=1479773519',
                            'VariationSpecificValue': 'Wine'
                        }
                    ]
                }
            }
        }})
        #dump(api, full=False)
        return response


    except ConnectionError as e:
        print(e)
        print(e.response.dict())

...当我检查实际发出的请求时，产生了预期的XML：

<?xml version='1.0' encoding='utf-8'?>
<ReviseItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">
    <RequesterCredentials>
        <eBayAuthToken>...</eBayAuthToken>
    </RequesterCredentials>
    <Item>
        <ItemID>332121070278</ItemID>
        <Variations>
            <Pictures>
                <VariationSpecificPictureSet>
                    <ExternalPictureURL>https://cdn.shopify.com/s/files/1/0740/6535/products/wine_1_43df4936-4a20-4419-8643-40575a9bb457.jpg?v=1479773519</ExternalPictureURL>
                    <PictureURL>https://cdn.shopify.com/s/files/1/0740/6535/products/wine_1_43df4936-4a20-4419-8643-40575a9bb457.jpg?v=1479773519</PictureURL>
                    <VariationSpecificValue>Wine</VariationSpecificValue>
                </VariationSpecificPictureSet>
            </Pictures>
        </Variations>
    </Item>
</ReviseItemRequest>

对我来说似乎完全正确。我可以使其他ReviseItem api调用有效（例如，我可以使用ReviseItem成功更改列表的标题），但更改Variation图像每次都会给我错误"ReviseItem: Class: RequestError, Severity: Error, Code: 10007, Internal error to the application. Internal error to the application."

Answer 1

原来，API不接受没有VariationSpecificName的VariationSpecificPictureSet。我上面的api调用完全适用于一个小修正：

[('1920', '1930')]

通过Trading API以编程方式更改Ebay图片
