how to unmarshal simple json with lowercase member into a struct

Question

I have a simple struct with string and int. When I unmarshal a json the struct members are not getting parsed if beginning with lowercase string .Even if I am using in the same package

package main

import (
    "encoding/json"
    "fmt"
)

type Bird struct {
  Species string
  Description string
  lifespan int
}




func main() {
    birdJson := `{"species": "pigeon","description": "likes to perch on rocks","lifespan": 9}`
    var bird Bird   
    json.Unmarshal([]byte(birdJson), &bird)
    fmt.Printf("Species: %s, Description: %s,lifespan: %d", bird.Species, bird.Description,bird.lifespan)
    //Cant read the lifespan ??
}

You must export struct fields. Change `lifespan` to `Lifespan`. — icza, Jul 31 '20 at 08:23

lifespan int

needs to be

Lifespan int

you can't unmarshal into an unexported field
