# Example Example of using the AWS SDK for Go with an HTTPS_PROXY that requires client TLS certificates. The example will use the proxy configured via the environment variable `HTTPS_PROXY` proxy a request for the Amazon S3 `ListBuckets` API operation call. The example assumes credentials are provided in the environment, or shared credentials file `~/.aws/credentials`. The `certificate` and `key` files paths are required to be specified when the example is run. An certificate authority (CA) file path can also be optionally specified. Refer to [httpproxy.FromEnvironment](https://godoc.org/golang.org/x/net/http/httpproxy#FromEnvironment) for details using `HTTPS_PROXY` with the Go HTTP client. ## Usage: ```sh export HTTPS_PROXY=https://127.0.0.1:8443 export AWS_REGION=us-west-2 go run -cert -key [-ca ] ```
