使用 AWS 签名在 HTTParty 中重新创建邮递员发布请求

Question

I have a custom API that needs to pass in an AWS access key, secret key, and region. I'm able to generate results from the post requests in Postman when I place these credentials in Authorization headers under AWS signature type. But I'm not sure the proper syntax to pass in for HTTParty in ruby.

This is my current request expression:

response = HTTParty.post(BASE_URL, :body => data.to_json, :headers => {'Content-Type' => 'application/json'})

All examples I see are Authorization passing in a token. But in postman I'm passing the access key, secret key and region. Do I need to generate a token before this? If so, how?

AWS has a ruby gem for this, aws-sigv4 (assuming that's the version you need in your case, double check) that allows you to pass in your credentials, region, and request to create a signature. It returns a hash of headers that act as its signature, which you can pass to HTTParty with the rest of the request details.
