Question

您可以使用此代码获取亚马逊上某个特定项目的第一张图片网址：

         col1   col2   col3   col4
row1     65      24     47     35
row2     33      48     25     89
row3     65      34     67     34
row4     24      12     52     17

但是如何才能获得该项目的所有图片网址，而不是仅获取第一个？感谢。

Answer 1

您需要在请求中包含“图片”响应组。

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

然后可以通过images属性访问XML ImageSets列表，但需要使用XML解析器进行解析。

product.images

请查看本文，了解有关在python中解析XML的信息： How do I parse XML in Python?

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

从图书馆的源代码：

@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如下所示：

  <ImageSet Category="primary">
  <SwatchImage>
