lambda.md

invoke lambda in aws cli 2

AWS_REGION=us-east-1 aws lambda invoke \
                      --function-name goad \
                      --invocation-type Event \
                      --payload file://payload.json \
                      --cli-binary-format raw-in-base64-out \
                      out.txt

if payload is long enough, just put it in payload.json, and use --cli-binary-format raw-in-base64-out 如果payload的内容很长，可以将其存储在payload.json里，然后用--cli-binary-format raw-in-base64-out

AWS V2 defaults to base 64 input. For your case to work, simply add a --cli-binary-format raw-in-base64-out parameter to your command.
