softius / negotiator

A content negotiation package for web applications in Go

Negotiator

This is a libary that handles content negotiation in web applications written in Go.

Usage

Simple

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)
}

Custom

To add your own negotiator, for example you want to write a PDF with your model, do the following:

1. Create a type that conforms to the ResponseProcessor interface

2. Call negotiator.New(responseProcessors ...ResponseProcessor) and pass in a your custom processor. When your request handler calls negotiator.Negotiate(w,req,model,errorHandler) it will render a PDF if your Accept header defined it wanted a PDF response.
