我试图在https://www.realestate.com.au/sold/in-brisbane+-+greater+region,+qld/list-1上抓取一些真实的地产数据。调用fetch('https://www.realestate.com.au/sold/in-brisbane+-+greater+region,+qld/list-1')，返回以下错误：

[scrapy.downloadermiddlewares.retry] DEBUG: Retrying <GET https://www.realestate.com.au/sold/in-brisbane+-+greater+region,+qld/list-1> (failed 1
times): 429 Unknown Status

有没有人知道如何绕过这个？我试过玩settings.py中的设置，但无济于事。

在这种情况下，最有可能的是网站正在阻止您的请求，因为它无法识别您。
使用Request Headers和Cookies-这是一种反禁令的方法来刮网站，这被称为Reverse Engineering the request.所以你打开浏览器工具，并复制粘贴- Request Headers，Cookies.使用它来请求网站.
下面的代码为我工作（检查代码下面的截图）。让我知道，如果有任何其他的疑问。
快乐刮痧：）

我不认为返回的错误429与实际请求太多有关，但它确实是一种防刮擦措施。也就是说，我可以通过请求获得数据：
