HOP

Handler OPerators

You can add pre operations to your http.HandlerFunc

op1 - op2 - op3 - ... - your http.HandlerFunc

Example

Gets Contenty-Type(MIME type) Header

import (
    "github.com/mokelab-go/hop"
)

// main handler
handler := func(w http.ResponseWriter, r *http.Request) {
    contentType := hop.ContentType(r.Context())
    fmt.Fprintf(w, "Content type is %s", contentType)
}
handler = op.Operations(op.GetContentType)(handler)

Functions

func BodyJSON

func BodyJSON(c context.Context) map[string]interface{}

BodyJSON returns request body as JSON(map[string]interface{}) format

func ContentType

func ContentType(c context.Context) string

ContentType returns Content-Type header

func GetBodyAsJSON

func GetBodyAsJSON(next http.HandlerFunc) http.HandlerFunc

GetBodyAsJSON returns handler, this handler decodes request body as JSON format.

func GetContentType

func GetContentType(next http.HandlerFunc) http.HandlerFunc

GetContentType returns handler, this handler gets Content-Type

func GetCredential
