BuildStatus Coverage Status GoDoc status

Package gojison provides two simple middlewares for working with JSON data in goji and two simple helper function to write out Error and Success responses to the http.RequestWriter.

Example

package main

import (
    "fmt"
    "net/http"

    "github.com/zenazn/goji"
    "github.com/zenazn/goji/web"
    "github.com/ndyakov/whatever"
    "github.com/ndyakov/gojison"
)

func main() {
    goji.Use(gojison.Request)
    goji.Use(gojison.Response)
    goji.Post("/save", handleSave)
    goji.Serve()
}

func handleSave(c web.C, w http.ResponseWriter, r *http.Request) {
    params := c.Env["Params"].(whatever.Params)
    if err := params.Required("user.name", "user.email"); err != nil {
        gojison.Error(err, 0)
        return
    }
    // do something...
    gojison.Success("saved", 0)
}

Middlewares

This package includes the following middlewares:

Response:

This middleware will set the content type of the response to "application/json"

Request:

This middlware will unmarshal the request parameters to an whatever.Params structure and then attach it to the goji context map. You can access that structure from the context and work with it as either map[string]iterface{} or whatever.Params

For more information about how to work with the whatever.Params type, please refer to: http://godoc.org/github.com/ndyakov/whatever

Helpers

gojison exports two helper functions:

  • Error(w http.ResponseWriter, err error, code int)
  • Success(w http.ResponseWriter, message string, code int)

Those helpers can be used to render an error or success message as json and set the response code.

If the response code argument is 0, the following will be used:

  • 400(http.StatusBadRequest) for Error
  • 200(http.StatusOK) for Success
