从Python中获取现有Shopify产品图像的源URL

我基本上无法查看如何存储Shopify图像网址以及我应该写什么来访问它。我不是蟒蛇专家,所以它可能是我看不到的简单。

Shopify有一个API,允许应用开发者从商店访问产品,订单等。我能够获得我店铺所有产品的清单,并获取标题和价格等信息,但我无法抓住图片网址。以下是一些基本代码,说明正在发生的事情和我需要的内容:

import shopify

#other code that accesses my shop

products = shopify.Product.find() #Here I grab a list of all the products
for product in products:
    title = product.title
    price = float(product.variants[0].price) #I'm not sure on the price either, but it works for now
    image_urls = create_image_url_list(product.images) # And here's where I want to create the list of strings using product.images

create_image_url_list(product_images):
    image_urls = []
    for image in product_images:
        product_image_url = '' # Somehow get source url from product image here as string
        image_urls.append(product_image_url)
    return image_urls

我相信每个产品都有一个图像列表。我希望能够做的是为每个产品创建一个图像源URL列表作为字符串。查看Shopify API Documentation for Product,我看到product.images属性如下所示:

{ "images" : "[ { "src": "http://example.com/burton.jpg" } ]"}

当我在product.images上执行pdb.set_trace()时,它看起来像这样(我更改了隐私号码):

[image(12345678), image(12345678), image(12345678), image(12345678)]

当我在其中一张图片上执行dir()时,我得到了这个:

['_ShopifyResource__get_id', '_ShopifyResource__set_id', '_ShopifyResource__to_xml_element', '__class__', '__cmp__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattr__', '__getattribute__', '__hash__', '__init__', '__metaclass__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_build_list', '_build_object', '_class_delete', '_class_get', '_class_head', '_class_post', '_class_put', '_collection_path', '_connection', '_custom_method_collection_url', '_custom_method_element_url', '_custom_method_new_element_url', '_element_path', '_find_class_for', '_find_class_for_collection', '_find_every', '_find_one', '_find_single', '_format', '_headers', '_id_from_response', '_initialized', '_instance_delete', '_instance_get', '_instance_head', '_instance_post', '_instance_put', '_load_attributes_from_response', '_password', '_plural', '_prefix', '_prefix_options', '_prefix_parameters', '_prefix_source', '_primary_key', '_query_string', '_singular', '_site', '_split_options', '_threadlocal', '_timeout', '_update', '_user', 'activate_session', 'attach_image', 'attributes', 'clear_session', 'count', 'create', 'delete', 'destroy', 'errors', 'exists', 'find', 'find_first', 'find_one', 'get', 'get_id', 'head', 'id', 'is_new', 'is_valid', 'klass', 'post', 'put', 'reload', 'save', 'set_id', 'to_dict', 'to_xml']

编辑:

在Pawelmhm的帮助下,访问源URL的结果代码是:

products = shopify.Product.find() #Here I grab a list of all the products
for product in products:
    title = product.title
    price = float(product.variants[0].price)
    image_urls = [getattr(i, 'src') for i in product.images] # Reduced it to list comprehension using solution

答案 0 :(得分:1)

我想我知道你在找什么,product_images是一个“类字典”对象,其中“images”作为键,字典列表作为值。你尝试过这样的事吗?

for image in product_images:
     #product_image_url = '' 
     image_urls.append(image["images"])

或者也许?

for image in product_images.to_dict():
     image_urls.append(image["images"]["src"])

告诉我它是否有效,如果它没有告诉我你得到了什么错误。我对此很好奇。当你按照自己的方式行事时,你会得到什么(你在这里发布的代码方式)?我的意思是没有这个空字符串当然会取消所有内容,但没有空字符串,你得到的是什么列表?

编辑:啊,这应该有效!

for image in product_images: 
     image_urls.append(image["src"])
