从Amazon API获取所有图像URL [英] Get all image URLs from Amazon API

问题描述

您可以使用以下代码获取亚马逊上某个特定商品的第一个图片网址:

You can use this code to get the first image URL of one specific item on amazon:

from amazon.api import AmazonAPI

amazon = AmazonAPI(aws_key='XXX', aws_secret='XXX', aws_associate_tag='XXX', region="DE")
product = amazon.lookup(ItemId='B003P0ZB1K')
print(product.large_image_url)

但是如何获得该项目的所有图像URL，而不是仅获得第一个?谢谢.

but how can you get to all image URLs of that item, instead of only getting the first one? Thanks.

推荐答案

您需要在请求中包括图片"响应组.

You need to include the 'Images' response group in your request.

product = amazon.lookup(ItemId ='B003P0ZB1K'，ResponseGroup ='Images')

然后可以通过images属性访问XML ImageSet的列表，但是需要使用XML解析器进行解析.

The list of XML ImageSets can then be accessed via the images property, but will need to be parsed using an XML parser.

product.images

参考: https://docs.aws.amazon.com/AWSECommerceService/latest/DG/RG_Images.html

从库的源代码中:

@property
def images(self):
    """List of images for a response.
    When using lookup with RespnoseGroup 'Images', you'll get a
    list of images. Parse them so they are returned in an easily
    used list format.
    :return:
        A list of `ObjectifiedElement` images
    """
    try:
        images = [image for image in self._safe_get_element(
            'ImageSets.ImageSet')]
    except TypeError:  # No images in this ResponseGroup
        images = []
    return images

图像集XML看起来像这样:

The image set XML looks like this:

<ImageSets>
  <ImageSet Category="primary">
