亚马逊MWS的Boto方法GetLowestPricedOffersForSKU

Question

Boto提供对大多数亚马逊MWS API的访问,但不提供对GetLowestPricedOffersForSKU的访问.我试图破解一个,但它会产生Invalid MarketplaceId错误.

Boto有一个结构非常相似的API代码 - GetLowestOfferListingsForSKU:

@requires(['MarketplaceId', 'SellerSKUList'])
@structured_lists('SellerSKUList.SellerSKU')
@api_action('Products', 20, 5, 'GetLowestOfferListingsForSKU')
def get_lowest_offer_listings_for_sku(self, request, response, **kw):
    """Returns the lowest price offer listings for a specific
       product by item condition and SellerSKUs.
    """
    return self._post_request(request, kw, response)

所以我修改了@api_action将MWS操作更改为GetLowestPricedOffersForSKU:

### MINE ###
@requires(['MarketplaceId', 'SellerSKUList'])
@structured_lists('SellerSKUList.SellerSKU')
@api_action('Products', 20, 5, 'GetLowestPricedOffersForSKU')
def get_lowest_priced_offers_for_sku(self, request, response, **kw):
    return self._post_request(request, kw, response)

我将此方法称为如下:

conn = connection.MWSConnection(
    aws_access_key_id=ACCESS_KEY,
    aws_secret_access_key=SECRET_KEY,
    Merchant=ACCOUNT_ID
)
response = conn.get_lowest_priced_offers_for_sku(
    MarketplaceId=marketplace_id, SellerSKUList=sku_list, ItemCondition=condition
)

当我打电话时get_lowest_priced_offers_for_sku,我收到一个Invalid MarketplaceId错误.如果我做的唯一更改是调用get_lowest_offer_listings_for_sku- 保持每个变量相同 - 代码可以找到并返回一个有效的响应对象.这很好用:

response = conn.get_lowest_offer_listings_for_sku(
    MarketplaceId=marketplace_id, SellerSKUList=sku_list, ItemCondition=condition
)

如何通过boto访问亚马逊MWS GetLowestPricedOffersForSKU需要做什么？

Answer 1

不确定，我也不是 python 程序员，但在 PHP AmazonMWS API 中，我使用下面的代码，其中使用 setMarketplaceId()

$request = new MarketplaceWebServiceProducts_Model_GetLowestPricedOffersForSKURequest();
$request->setSellerId($this->seller_id);
$request->setMarketplaceId($this->marketplace_id);
$request->setItemCondition("New");
