英文:
redirecting to another domain with AWS lambda whilst keeping the path
问题
https://aws.amazon.com/blogs/compute/redirection-in-a-serverless-api-with-aws-lambda-and-amazon-api-gateway/ 介绍了如何使用AWS Lambda进行HTTP 301/302重定向，但似乎没有讨论如何在保留路径的情况下执行重定向。
以下是他们提供的代码：
// 返回 302 或 301
var err = new Error("HandlerDemo.ResponseFound Redirection: Resource found elsewhere");
err.name = "http://a-different-uri";
context.done(err, {});
与其将请求从 http://oldwebsite.com/aaa 重定向到 http://newwebsite.com/，我想将它们重定向到 http://newwebsite.com/aaa。
有关如何实现这一点的想法吗？

https://aws.amazon.com/blogs/compute/redirection-in-a-serverless-api-with-aws-lambda-and-amazon-api-gateway/ talks about how to do HTTP 301/302 redirects with AWS Lambda but it doesn't seem to discuss how to do the redirect whilst preserving the path.
Here's the code that they provide:
// Returns 302 or 301
var err = new Error("HandlerDemo.ResponseFound Redirection: Resource found elsewhere");
err.name = "http://a-different-uri";
context.done(err, {});
Instead of directing requests from http://oldwebsite.com/aaa to http://newwebsite.com/ I'd like to direct them to http://newwebsite.com/aaa.
Any ideas as to how I might do that?

我在快速测试中进行了黑客攻击，重新使用了文章中的方法：
- 一个REST API，
- 一个返回错误的Lambda，
- 一个将错误转换为HTTP重定向的集成。
请求的路径位于event.path属性中，因此示例仅需要进行轻微更新：
exports.handler = async (event, context) => {
const path = event?.path;
var err = new Error('CustomError');
err.name = 'http://newwebsite.com' + path;
throw err;
};
另外需要注意的是，对于系统性重定向，HTTP API 可能更合适。在这种情况下，路径通过另一个属性（即event.rawPath）传入，Lambda 的结果将更像是一个HTTP响应。
英文:
I hacked a quick test, reusing the approach in the article:
- a REST API,
- a Lambda returning an error,
- an integration transforming the error into an HTTP redirect.
The requested path comes in the event.path attribute, so the example requires only minor updates:
exports.handler = async (event, context) => {
const path = event?.path;
var err = new Error('CustomError');
err.name = 'http://newwebsite.com' + path;
throw err;
};
A a side note, an HTTP API is probably a better fit for a systematic redirect.
In this case the path is coming through another attribute (ie. event.rawPath) and the Lambda result will look more like an HTTP response.
