Query Api and response a custom JSON, how to Unmarshal it. the sample JSON:

"14AcKEr19gHJvgwQhK7sfFm6YJGmoZZoqu": 
"final_balance": 61914248289,
"n_tx": 3472,
"total_received": 3479994002972

The key is a hex string. So how to handle it with golang convention, anyone can help me?

Below is my try test code:

c.OnResponse(func(r *colly.Response) 
 jsonData := r.Body

 fmt.Println(string(jsonData))
 fmt.Println("==================")

 //parse bitcoin json
 jsonMap := make(map[string]interface)
 err := json.Unmarshal(byte(jsonData), &jsonMap)
 if err != nil 
 panic(err)
 

 fmt.Println(jsonMap)

 dumpMap("", jsonMap)
)

func dumpMap(space string, m map[string]interface) 
 for k, v := range m 
 if mv, ok := v.(map[string]interface); ok 
 fmt.Printf(" "%v": n", k)
 dumpMap(space+"t", mv)
 fmt.Printf("n")
 else 
 fmt.Printf("%v %v : %vn", space, k, v)
 
 

and go run cmd/main.go, the console is print here:

"14AcKEr19gHJvgwQhK7sfFm6YJGmoZZoqu": 
 "final_balance": 75494521080,
 "n_tx": 3493,
 "total_received": 3493574275763

==================
map[14AcKEr19gHJvgwQhK7sfFm6YJGmoZZoqu:map[n_tx:3493 total_received:3.493574275763e+12 final_balance:7.549452108e+10]]
 "14AcKEr19gHJvgwQhK7sfFm6YJGmoZZoqu":
 final_balance : 7.549452108e+10
 n_tx : 3493
 total_received : 3.493574275763e+12

Do I need customised unmarshal func to get string key? If I use 14AcKEr19gHJvgwQhK7sfFm6YJGmoZZoqu as key I can't easily to access. I just want to know how handle it.

you can unmarshal it into map, so you can get generated key as a key of map

package main

import (
 "encoding/json"
 "fmt"
 "log"
)

var input = `"14AcKEr19gHJvgwQhK7sfFm6YJGmoZZoqu": 
"final_balance": 61914248289,
"n_tx": 3472,
"total_received": 3479994002972
`

type object struct 
 FinalBalance uint64 `json:"final_balance"`
 NTX uint64 `json:"n_tx"`
 TotalReceived uint64 `json:"total_received"`


func main() 
 var result map[string]object;
 err := json.Unmarshal(byte(input), &result);
 if err != nil 
 log.Fatal(err)
 

 fmt.Printf("result: %+v", result)
 // result: map[14AcKEr19gHJvgwQhK7sfFm6YJGmoZZoqu:FinalBalance:61914248289 NTX:3472 TotalReceived:3479994002972]
