GoLang | Transferring the data coming with the post to the interface

Question

I'm doing a post operation like this, can you let me know how I can carry it to the interface?

I tried many ways, I gave any type without string. I'm a little new to this language, I created the logic but I couldn't apply it...

package main

import (
    "bytes"
    "encoding/json"
    "fmt"
    "io"
    "net/http"
)

const (
    RPC_URL string = "https://rpc.blurt.world"
)

func main() {
    values := map[string]string{
        "jsonrpc": "2.0",
        "id":      "1",
        "method":  "condenser_api.get_account_history",
        "params":  `["post24", -1, 10]`,
    }

    jsonValue, _ := json.Marshal(values)

    resp, err := http.Post(RPC_URL, "application/json", bytes.NewBuffer(jsonValue))
    if err != nil {
        fmt.Printf("wanted in error http post request: %v", err)
    }

    // defer resp.Body.Close()
    defer func(Body io.ReadCloser) {
        err := Body.Close()
        if err != nil {

        }
    }(resp.Body)

    var response map[string]interface{}

    err = json.NewDecoder(resp.Body).Decode(&response)
    if err != nil {
        fmt.Printf("wanted in error json decode: %v", err)
    }

    fmt.Printf("%v", response)
}
