Thanks for the PR. I think adding a way to force POST is a useful feature, especially in case you have big payloads etc.

1. Can we handle the scenario where there are more than 1 component and method=GET? I think in that case, we should probably return with an exception or error, as the GET only allows one component.

2. Can we add some unit or acceptance tests for the various scenarios (empty|GET|POST|GET+multiple components exception)?

3. Can you update the README for documenting the new method parameter?

Thanks!

Absolutely. I'll get back to you in a few days with an updated PR. Thanks.

This is not ready for review just yet. I meant to push this to my fork but for some reason it got picked up.
