This is a libary that handles content negotiation in web applications written in Go.
To return JSON/XML out of the box simple put this in your route handler:
func getUser(w http.ResponseWriter, req *http.Request) {
user := &User{"Joe","Bloggs"}
negotiator.Negotiate(w, req, user, GlobalErrorHandler)
}
To add your own negotiator, for example you want to write a PDF with your model, do the following:
-
Create a type that conforms to the ResponseProcessor interface
-
Call
negotiator.New(responseProcessors ...ResponseProcessor)and pass in a your custom processor. When your request handler callsnegotiator.Negotiate(w,req,model,errorHandler)it will render a PDF if your Accept header defined it wanted a PDF response.
