我正在嘗試向 Zalando 索取所有尺寸的庫存。我不太清楚該怎么做，因為我正在觀看的視頻顯示如何請求尺寸看起來與最小值不同。我看的視頻是這樣的。視頻 - 5.30
有誰知道如何索取庫存尺寸并列印庫存尺寸？
試圖請求大小的站點：這里
我的代碼如下所示：
import requests
from bs4 import BeautifulSoup as bs
session = requests.session()
def get_sizes_in_stock():
global session
endpoint = "https://www.zalando.dk/nike-sportswear-air-max-90-sneakers-ni112o0bt-a11.html"
response = session.get(endpoint)
soup = bs(response.text, "html.parser")
我試圖轉到查看頁面源并查找尺寸，但我無法在頁面源中看到尺寸。
我希望有人可以幫助我做什么。

尺寸在頁面中
我在 html 中找到了它們，在 javascript 標記中，格式為
{
"sku": "NI112O0BT-A110090000",
"size": "42.5",
"deliveryOptions": [
{
"deliveryTenderType": "FASTER"
}
],
"offer": {
"price": {
"promotional": null,
"original": {
"amount": 114500
},
"previous": null,
"displayMode": null
},
"merchant": {

如果您使用 bs4 決議 html，您應該能夠找到腳本標簽并提取 JSON。

鞋子默認顏色的尺寸以 html 格式顯示。除此之外，還有其他顏色的網址。您可以將它們提取到字典和回圈中，發出請求并提取不同的顏色及其可用性，我認為這是您實際請求的內容，如下所示（注意：我保持非常通用以避免硬編碼鍵在請求之間發生變化） ：
import requests, re, json
def get_color_results(link):
headers = {"User-Agent": "Mozilla/5.0"}
r = requests.get(link, headers=headers).text
data = json.loads(re.search(r'(\{"enrichedEntity".*size.*)<\/script', r).group(1))
results = []
color = ""
for i in data["graphqlCache"]:
if "ern:product" in i:
if "product" in data["graphqlCache"][i]["data"]:
if "name" in data["graphqlCache"][i]["data"]["product"]:
results.append(data["graphqlCache"][i]["data"]["product"])
if (
color == ""
and "color" in data["graphqlCache"][i]["data"]["product"]
):
color = data["graphqlCache"][i]["data"]["product"]["color"]["name"]
return (color, results)
link = "https://www.zalando.dk/nike-sportswear-air-max-90-sneakers-ni112o0bt-a11.html"
final = {}
color, results = get_color_results(link)
colors = {
j["node"]["color"]["name"]: j["node"]["uri"]
for j in [
a
for b in [
i["family"]["products"]["edges"]
for i in results
if "family" in i
if "products" in i["family"]
]
for a in b
]
}
final[color] = {
j["size"]: j["offer"]["stock"]["quantity"]
for j in [i for i in results if "simples" in i][0]["simples"]
}
for k, v in colors.items():
if k not in final:
color, results = get_color_results(v)
final[color] = {
j["size"]: j["offer"]["stock"]["quantity"]
for j in [i for i in results if "simples" in i][0]["simples"]
}
print(final)
