问题 I have some lambda functions and I usually grant access to thirds devs to my AWS account. They eventually can request my lambda functions for working or testing purposes but I want to prevent them to download the source code. Is there a way to manage who can download (or not) my lambda files ? 回答1: This will come down to the specifics of how they test the lambda; specially, how your lambda is configured and the users access permissions. Typically there is 3 scenarios that could play out here:

问题 I'm new to Python, I got a small script to upload files to S3, at the moment I only hard-code one single file in the script, the bucket name is also hard-coded.

For example, in the command line I can specify arguments to decide file_name x upload to bucket_name xxx .

问题 I'm working with AWS Amplify to develop an iOS application. I've added storage through S3 to host some assets and am trying to configure the application to download them. The only issue is that every example I see has the bucket name and path hardcoded, but because I have multiple environments and make new environments sometimes and each bucket has the environment name appended to it, I don't want to have to rewrite the bucket name each time. For example if I'm in my test environment the

问题 We currently have an internal library that we're using to make a lot of our HTTP calls that uses RestSharp rather that the HttpClient to make all of our requests to downstream services. Is it possible to enable x-ray tracing in AWS without re-writing that library to instead use HttpClient? The goal is to get the same functionality that would be outlined here (when using HttpClient): https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-dotnet-httpclients.html 回答1: The RestSharp library is
