Controlling where HTTP requests go in AWS

问题:

If I have a static site on AWS S3 (and maybe using CloudFront) that's pretty cool, because it scales easily, and has zero-downtime deployments, because you're just updating static assets, and gets distributed to edge locations, woohoo!

But, if I want to have a contact form, or process a stripe payment. I need to run some backend code. So, how do I tell AWS that for GETs to certain routes, use S3 (or CloudFront), but if there's a form submit, direct that to this little Lambda function over here?

Could I use Route53 and direct everything at example.com/forms/... over to Lambda?

回答1:

Route53 is just DNS, it doesn't do any routing based on the path. Since you are using CloudFront I believe you can use the CloudFront Behaviors feature to perform the routing you are talking about, like what is described in this blog post. Alternatively, just use a different subdomain for the dynamic parts of your web application like api.example.com for your API Gateway routes.
