Unmarshmaling json to nested struct

I have different json byte inputs that I need to unmarshal into a nested json structure. I am able to unmarshal the json into the struct App. However I am unable to add to "status" struct.

I tried to unmarshal, but that doesnt work since my app1 & app2 are of type App instead of bytes. And trying to set directly gives the error "cannot use app1 (type App) as type []App in assignment"

package main

import (
	"encoding/json"
	"fmt"
	"reflect"
)

type App struct {
	Appname string `json:"appname"`
	Builds  string `json:"builds"`
}

type Status struct {
	Apps []App `json:"apps"`
}

func main() {
	jsonData1 := []byte(`
			{  
			   "appname": "php1",
			   "buildconfigs":"deleted"
			}
		`)

	jsonData2 := []byte(`
			{  
			   "appname": "php2",
			   "buildconfigs":"exists"
			}
		`)

	// unmarshal json data to App
	var app1 App
	json.Unmarshal(jsonData1, &app1)

	var app2 App
	json.Unmarshal(jsonData2, &app2)

	var status Status
	//json.Unmarshal(app1, &status)
	//json.Unmarshal(app2, &status)

	status.Apps = app1
	status.Apps = app2

	fmt.Println(reflect.TypeOf(app1))
	fmt.Println(reflect.TypeOf(app1))
}

You can't assign single element to array field so convert your

status.Apps = app1
status.Apps = app2

to something like

status.Apps = []App{app1, app2}

or

status.Apps = []App{}
status.Apps = append(status.Apps, app1)
status.Apps = append(status.Apps, app2)

Also your JSON field named buildconfigs and in struct specification json:"builds". Structure's field always will be empty in this case.

Your question is a bit confusing to me :s But if you modify your JSON data to an JSON array and it will work with Unmarshal and could be unmarshal to status with no problems:

func main() {
    jsonData1 := []byte(`
            {  
               "apps": [{
                   "appname": "php1",
                   "buildconfigs":"deleted"
                },{  
                   "appname": "php2",
                   "buildconfigs":"exists"
                }]
            }
        `)

    var status Status
    json.Unmarshal(jsonData1, &status)
    fmt.Printf("%+v\n", status)
}
