AWS API Gateway:传递引荐来源网址

问题描述：

对API网关的请求是否有可能将引荐来源网址传递给Lambda?例如，我很想让我的lambda函数知道请求是否来自域名"good.com"和"bad.com".

Is it possible for requests to the API-Gateway to pass the referrer URL to Lambda? For example, I'd love to let my lambda functions know if a request comes from the domain "good.com" vs. "bad.com".

我熟悉受支持的$ context变量，我知道其中没有引荐来源网址.我想知道是否还有另一种方式.如果有可能，我需要采取什么步骤?

I'm familiar with the list of supported $context Variables and I know a referrer url is not in there. I'm wondering if there is another way. If it is possible, what steps do I need to take?

答

此处是操作方法.

事实证明，该映射模板允许您映射 HTTP标头，而不仅仅是支持的变量列表在文档中.

包含引荐来源网址域的HTTP标头称为来源".包含引用页面URL的标题称为引用".

The HTTP header that contains the referrer domain is called "Origin". The header that contains the referer page URL is called "Referer".

因此，例如，您可以将其放在映射模板中，它将获取关联的标头信息:

So, for example, you can put this in your mapping template and it will grab the associated header information:

{
"origin" : "$input.params('origin')",
"referer" : "$input.params('referer')"
}

Origin抓取example.com.引荐来源抓住example.com/pagename

Origin grabs example.com. Referer grabs example.com/pagename
