nego

Go package providing an implementation of HTTP Content Negotiation compliant with RFC 7231.

As defined in RFC 7231 the following request headers are sent by a user agent to engage in a proactive negotiation of the response content: Accept, Accept-Charset, Accept-Language and Accept-Encoding. This package provides convenient functions to negotiate the best and acceptable response content type, charset, language and encoding.

Installation

		contentCharset := nego.NegotiateContentCharset(req, "utf-8")
		contentEncoding := nego.NegotiateContentEncoding(req, "gzip", "deflate")
		contentLanguage := nego.NegotiateContentLanguage(req, "fr", "en")
