我想刮擦数据，但是我只能第一次成功请求，当我重新运行时，我无法再次获得身体。

pageSkimData = requests.get(url, headers=request_headers)
treeSkimData = html.fromstring(pageSkimData.content)
它也发生在我身上，一旦我提出了初始请求，源为所有后续请求略有更改，以获取可能忘记结果的数据并使用 product product divs：
pageSkimData = requests.get(url, headers=request_headers)
treeSkimData = html.fromstring(pageSkimData.content)
print(pageSkimData.content)
for prod in treeSkimData.xpath("//div[@class='product icon-chevron-small-right prodwithad clearfix']"):
print(prod.xpath("./div[@class='producttitle']/h2/a/text()")[0])
for li in prod.xpath("//ul[@class='product-feature-list']/li/span"):
print(li.xpath("./strong/text()")[0] + li.xpath("./span/text()")[0])
