At my work, we use JSON-RPC based APIs very heavily, in particular with our PHP JSON-RPC library php-json-rpc. While JSON-RPC is not as wide spread as REST, it fits our needs quite nicely. In particular, it is protocol independent and can be used over HTTP, SSH or as local CLI. With our library and its numerous extensions (HTTP, SSH, authentication, validation, request-to-class mapping and logging), development is super fast and incredibly easy.
In this post, I’d like to demonstrate how to set up a PHP based JSON-RPC API, with authentication, validation and logging.
