python-3.x 发出带参数的get请求后，无法生成200状态

我正在尝试向网页发送GET HTTP请求，并收到200状态响应。在发出请求时，需要通过链路发送适当的参数。但是，当我使用link和payload发送请求时，我总是收到410状态码。
当我在下面的代码中直接使用从开发工具复制的URL时，我得到一个200状态。
请注意，我已经修改了AnchorProdSetId和ProdSetId的值，然后才用链接发送有效负载。
在使用带有有效负载的链接发出请求后，如何获得200（检测到时为403）状态？

似乎这个服务器返回brotli压缩响应。要从服务器获取200响应，请安装brotli包：

pip install brotli

然后：

import requests

url = "https://www.mcmaster.com/mv1687879695/WebParts/Content/ContentWebPart.aspx?cntnrIDtxt=ProdPageContent&srchidtxt=5875341805879&cntnrwdth=1001&srchrslttxt=screws&GrpUsrInps=%5B%7B%22AnchorProdSetId%22%3A%22-3383254440195390%22%2C%22AnchorStateIsSet%22%3Atrue%2C%22ClearAllProdSetId%22%3A-1%2C%22ClearAllStateIsSet%22%3Atrue%2C%22GrpEID%22%3A%22%22%2C%22ProdSetId%22%3A%22-3383254440195390%22%7D%5D&viewporthgt=296&cssAlias=undefined&usedynamicimageswapping=true&conditionalclientlandingpage=true&forcemdmfiltering=true&workstationdata=true&fwdSsToNav=true&fwdSsWpNav=true&fwdCrcWpNav=true&sortRowsOnServer=true&showbroadlandingpagecopy=true&filtSsAttrEarly=true&legImgContainsHash=true&clientNavigationEvents=%5B%5D&envrmgrcharsetind=5&useEs6=true"
r = requests.get(url)
print(r.status_code)

编辑：要获取“内六角螺钉”的内容：

import requests
