Golang parse JSON returns 0

The JSON that I am at tempting to parse is very basic and looks like this.

{"id": 3, "title":"Test"}

The following is the code that I am attempting to use for creating and parsing the JSON.

package main

import (
    "fmt"
    "encoding/json"
)

type Config struct{
    id int
    title string
}

func main() {
    var jsonStr = []byte(`{"id": 3, "title":"Test"}`)
    var conf Config
    err := json.Unmarshal(jsonStr, &conf)
    if err!=nil{
            fmt.Print("Error:",err)
    }
    fmt.Println(conf)
    fmt.Println(string(jsonStr))
}

Been looking over a lot of different code examples and can't see what I'm doing wrong. When I attempt to run this, this is what I get as a return.

{0 }
{"id": 3, "title":"Test"} 

I have verified that the JSON is valid, but continue to get an empty return when attempting to use json.Unmarshal. Any ideas on what I am missing so that I can get this JSON parsed?

EDIT: Looks like I can get this to work if I capitalize the titles (Id, Title). Unfortunately the return I am testing for is a return from an API which returns everything in lowercase. I need to be able to parse this JSON with lowercase titles as listed above.

Your Config struct's fields need to be exported (upper-case), but the keys in your JSON object may remain lower-case.

Please consult the JSON package documentation, it is worth the read. While Amit already addressed the export issue I will address the following:

> EDIT: Looks like I can get this to work if I capitalize the titles (Id, Title). Unfortunately the return I am testing for is a return from an API which returns everything in lowercase. I need to be able to parse this JSON with lowercase titles as listed above.

As you might imagine, the authors of encoding/json have thought of that, so again I encourage you to consult the documentation next time. The solution is this (Example on playground):

type Config struct {
	Id    int    `json:"id"`
	Title string `json:"title"`
}
