How can I read a json file into a struct, and then Marshal it back out to a json string with the Struct fields as keys (rather than the original json keys)?
(see Desired Output to Json File
below...)
Code:
package main
import (
"encoding/json"
"fmt"
"io/ioutil"
)
type Rankings struct {
Keyword string `json:"keyword"`
GetCount uint32 `json:"get_count"`
Engine string `json:"engine"`
Locale string `json:"locale"`
Mobile bool `json:"mobile"`
}
func main() {
var jsonBlob = []byte(`
{"keyword":"hipaa compliance form", "get_count":157, "engine":"google", "locale":"en-us", "mobile":false}
`)
rankings := Rankings{}
err := json.Unmarshal(jsonBlob, &rankings)
if err != nil {
// nozzle.printError("opening config file", err.Error())
}
rankingsJson, _ := json.Marshal(rankings)
err = ioutil.WriteFile("output.json", rankingsJson, 0644)
fmt.Printf("%+v", rankings)
}
Output on screen:
{Keyword:hipaa compliance form GetCount:157 Engine:google Locale:en-us Mobile:false}
Output to Json File:
{"keyword":"hipaa compliance form","get_count":157,"engine":"google","locale":"en-us","mobile":false}
Desired Output to Json File:
{"Keyword":"hipaa compliance form","GetCount":157,"Engine":"google","Locale":"en-us","Mobile":false}
