如何在AWS Lambda函数中获取AWS API Gateway调用URL? [英] How to get AWS API Gateway invoke URL in an AWS Lambda function?

问题描述

我正在将代理集成与Java lambda函数一起使用. lambda处理程序的输入是一个JSON对象，它表示传入的请求.它具有正文，标题，查询参数等.但是它不包括API网关为正文，查询参数等解析的源URL.有没有办法获取它?

I'm using the proxy integration with my Java lambda function. The input for the lambda handler is a JSON object that represents an incoming request. It has a body, headers, query params and so on. But it doesn't include the source URL that is parsed by the API Gateway for the body, query params and etc. Is there a way to get it?

问题是API网关不支持查询参数中的数组.示例:/endpoint?numbers=1&numbers=2.似乎，传递数组的唯一方法是将其作为JSON数组字符串/endpoint?numbers=[1,2]传递，但并不总是合适的.所以我想自己解析URL.

The thing is API Gateway doesn't support arrays in query parameters. Example: /endpoint?numbers=1&numbers=2. Seems, the only way to pass an array is to pass it as a JSON array string /endpoint?numbers=[1,2] but it is not always suitable. So I want to parse the URL by myself.

推荐答案

不幸的是，API Gateway并没有为您提供完整的URL来解析您自己.

Unfortunately, API Gateway doesn't provide you with the full URL for you to parse yourself.

如果可以选择将POST方法用于/endpoint，则可以考虑发送请求正文而不是查询字符串参数.

If you have the option of using the POST method to /endpoint, you might consider sending a request body instead of query string parameters.
