如何确定AWS Lambda函数中的当前区域? [英] How can one determine the current region within an AWS Lambda function?
问题描述
Regions.getCurrentRegion()
从AWS Lambda函数中返回null。 AWS Lambda函数似乎不支持 Regions.getCurrentRegion()
。是否有另一种方法可以确定lambda函数在哪个区域运行?
Regions.getCurrentRegion()
returns null from within an AWS Lambda function. It seems that Regions.getCurrentRegion()
is not supported from within an AWS Lambda function. Is there an alternative way to determine which region the lambda function is running in?
注意:AWS Lambda函数是用Java编写的。
NOTE: AWS Lambda function is written in Java.
推荐答案
您可以阅读 AWS_DEFAULT_REGION
环境变量并使用 Regions.fromName
将其解析为可用区域的函数。
You can read the AWS_DEFAULT_REGION
environment variable and use the Regions.fromName
function to parse that into a useable region.
Regions.fromName(System.getenv("AWS_DEFAULT_REGION"))
这比ARN解析方法的优点是你不需要一个Context对象,这意味着你可以在你的处理函数之外使用它。
The advantage of this over the ARN parsing approach is that you do not need a Context object which means you can use it outside of your handler function.
