这是URL https://www.lowes.com/store/AK-Anchorage/2955,当我们到达该URL时,如果我们单击该按钮,则按钮名称为“ Shop this store”,单击该按钮并使用链接发出的请求是相同的,但仍然单击该按钮将获得另一个页面,然后直接使用链接。我需要发出与按钮相同的请求。
我需要向“ https://www.lowes.com/store/AK-Anchorage/2955”发出请求,然后我需要做出与单击按钮相同的请求。
我试图连续两次发出请求,以获得所需的页面,但是没有运气。
url='https://www.lowes.com/store/AK-Anchorage/2955'
ua = UserAgent()
header = {'User-Agent':str(ua.chrome)}
response = requests.get(url, headers=header)
response = requests.get(url, headers=header)

因此,这似乎可行。两次都收到200 OK
响应,但内容长度不一样。
关于它的价值,在Firefox中,当我单击蓝色的“购买此商店”按钮时,它将带我到看似完全相同的页面,但没有单击蓝色按钮。在Chrome浏览器(测试版)中,当我单击蓝色按钮时,会显示一个403 Access denied
页面。他们的服务器运行不正常。您可能难以实现想要的目标。
如果我在没有标题的情况下呼叫session.get
,则根本不会得到响应。因此,他们显然正在检查用户代理,可能是cookie等。
import requests
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0",
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
"Accept-Language": "en-US,en;q=0.5",
"Accept-Encoding": "gzip, deflate, br",
"Upgrade-Insecure-Requests": "1",}
session = requests.Session()
url = "https://www.lowes.com/store/AK-Anchorage/2955"
response1 = session.get(url, headers=headers)
print(response1, len(response1.content))
response2 = session.get(url, headers=headers)
print(response2, len(response2.content))
输出:
<Response [200]> 56282
<Response [200]> 56323
我还做了一些测试。如果您没有更改默认Python Requests的user-agent
,则服务器超时。即使将其更改为""
似乎也足以使服务器给您响应。
您无需选择特定商店即可获取产品信息,包括描述,规格和价格。看看这个GET请求,它没有cookie,也没有会话:
import requests, json
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0"}
url = "https://www.lowes.com/pd/Google-Nest-Learning-Thermostat-3rd-Gen-Thermostat-and-Room-Sensor-with-with-Wi-Fi-Compatibility/1001080012"
r = requests.get(url, headers=headers, timeout=5)
print("return code:", r)
print("content length:", len(r.content))
for line in r.text.splitlines():
if "window.digitalData.products = [" in line:
print("This line includes the 'sellingPrice' and the 'retailPrice'. After some splicing, we can treat it as JSON.")
left = line.find(" = ") + 3
right = line.rfind(";")
print(json.dumps(json.loads(line[left:right]), indent=True))
break
输出:
return code: <Response [200]>
content length: 107134
This line includes the 'sellingPrice' and the 'retailPrice'. After some splicing, we can treat it as JSON.

产品说明和规格可在此元素中找到:

(大约300行,所以我只复制父标记。)
有一个API带有产品ID和商店编号,并返回价格信息:
import requests, json
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0"}
url = "https://www.lowes.com/PricingServices/price/balance?productId=1001080012&storeNumber=1955"
r = requests.get(url, headers=headers, timeout=5)
print("return code:", r)
print("content length:", len(r.content))
print(json.dumps(json.loads(r.text), indent=True))
输出:
return code: <Response [200]>

],

}
]
您可以使用此API获得有关每个商店的信息,该API返回一个1.6MB的 json 文件。 maxResults
通常设置为30
,而query
是您的经度和纬度。我建议将其保存到磁盘。我怀疑它会发生很大变化。
https://www.lowes.com/wcs/resources/store/10151/storelocation/v1_0?maxResults=2000&query=0%2C0
请记住,PricingServices/price/balance
端点可以为storeNumber
取多个值,并用%2C
(逗号)分隔,因此您不需要1763个单独的GET请求。我仍然使用requests.Session
发出了多个请求(因此它重复使用了基础连接)。
答案 1 :(得分:0)
这取决于您要如何处理数据。在URL中,您已经有商店ID。
点击按钮时,它会向https://www.lowes.com/store/api/2955
发送请求以获取商店信息。是您要找的东西吗?
如果是这样,您不需要两个请求,而只需要一个请求就可以获取所需的商店信息。
