原文摘录

摘自原文(2426 字符中的一小部分)
When libcurl is built with AWS SigV4 support, enabling **verbose logging** (`CURLOPT_VERBOSE` or `--verbose`) causes the library to print both the **string-to-sign** and the **final HMAC signature** into logs.
原文中的代码
AWS_ACCESS_KEY_ID=AWS_ACCESS_KEY... \
AWS_SECRET_ACCESS_KEY=SECRET... \
curl --aws-sigv4 "aws:amz:us-east-1:s3" \
     --verbose \
