parse

parse converts HTTP configuration values into types from Go's standard library.

import "github.com/containeroo/httpkit/parse"

Status codes

ParseStatusCodes accepts comma-separated status codes and inclusive ranges.

statusCodes, err := parse.ParseStatusCodes("200,300-302,404")
if err != nil {
	return err
}

// statusCodes is []int{200, 300, 301, 302, 404}

Headers

ParseHeaders accepts Key=Value entries and returns an http.Header. Header names are canonicalized, and commas or additional = characters in values are preserved.

headers, err := parse.ParseHeaders([]string{
	"Content-Type=application/json",
	"Accept=text/html, application/json",
	"X-Trace=one",
	"X-Trace=two",
}, true)
if err != nil {
	return err
}

// headers.Values("X-Trace") is []string{"one", "two"}

Pass false as the second argument to reject duplicate header names.
