- How to convert []int8 to string 4 answers
I want to do the read and write operation in the json file. I made a program for this But there is an error which occure while Unmarshalling the datathe code is given below:-
package main
import (
"encoding/json"
"fmt"
"io/ioutil"
)
type Page struct {
Id int `json:"_id" bson:"_id"`
Title string `json:"title" bson:"title"`
Type string `json:"type" bson:"type"`
Description string `json:"description" bson:"description"`
ProfileImage string `json:"profile_image" bson:"profile_image"`
DateTime int64 `json:"date_time" bson:"date_time"`
Author string `json:"author" bson:"author"`
Status int `json:"status" bson:"status"`
Slug string `json:"slug" bson:"slug"`
}
func main() {
plan, _ := ioutil.ReadFile("page.json")
var data interface{}
err := json.Unmarshal(plan, &data)
if err != nil {
fmt.Println(err)
}
if sl, ok := data.([]interface{}); ok {
counter := 0
for _, val := range sl {
counter++
md, _ := val.(map[string]interface{})
md["_id"] = counter
fmt.Println(md["_id"])
for _, k := range md {
// fmt.Println(k.([]byte))
rankings := Page{}
err = json.Unmarshal(k.([]uint8), &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)
}
}
}
}
It gives me the error of
panic: interface conversion: interface {} is string, not []uint8
