In a previous post, I discussed the design of go-restful which is a package for building REST-style WebServices using the Google Go programming language. Today, I completed the implementation of that package which provides the basics: Creating a WebService with Routes (mapping between Http Request and a Go function) Each Route requires information about the Http method (GET,POST,…), URL Path (/users..), Mime-types and the function it binds to Functions get passed in a Request and a Response The Request is used to access Path and Query parameters , Headers and request content (XML, JSON,…) The Response is used to set Status, Headers, and response content Both Request and Response can Unmarshal and Marshal objects to and from XML,JSON using the standard packages All of this can best be illustrated with a small example ; a Webservice for CRUD operations on User objects.
I have been using JAX-RS for many REST-based service implementations in Java. As part of my journey into the Google Go programming language, I am exploring designs for such REST support using the standard net/http package in Go. JAX-RS provides a set of Annotation classes which can be used to add meta-data to classes, methods and method arguments. In JAX-RS these annotation are used to specify the mapping between a Http Request to a Java method and its arguments.
