Golang将json的变量类型转换为字符串

我正在读取json中的API响应，并且遇到了json值（字符串，null，bool）内有多个数据类型的问题。另外，一些键的值可以是字符串或空值，这使得将数据读入类型变得更加困难。我想将所有内容都转换为字符串以便于处理。我创建了一个基于谷歌搜索其他例子的类型开关。我想知道这是否是最简单的方法，或者我错过了一个更简单的方法。Golang将json的变量类型转换为字符串

package main 

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

func main() { 

json_byte := []byte(`{"response":[{"t_int":1, "t_bool": true, "t_null_or_string": null}, {"t_int":2, "t_bool": false, "t_null_or_string": "string1"}]}`) 

//unmarshal the json to data structure using interface for variable data types 
data_json := make(map[string][]map[string]interface{}) //create a structure to hold unmarshalled json 
if err := json.Unmarshal(json_byte, &data_json); err != nil { 
    panic(err) 
} 
fmt.Println("json_data: ", data_json) 

//Iterate over data structure and convert Bool, Int, and Null types to string 
var v_conv string        // temporary holding for converted string values 
data_map := make(map[string]string)    // temporary holding for converted maps 
data_final := make([]map[string]string, 0, 100) // final holding for data converted to strings 

for _, v := range data_json { //v is the value of the "response": key which is a slice of maps 
    for _, v2 := range v { //v2 is one of the maps in the slice of maps 
     for k3, v3 := range v2 { //k3 and v3 are the keys and values inside the map 
      fmt.Println("k3: ", k3, "v3: ", v3) 
      switch v_type := v3.(type) { 
      case nil: 
       v_conv = "" 
      case bool: 
       v_conv = strconv.FormatBool(v3.(bool)) 
      case int: 
       v_conv = strconv.Itoa(v3.(int)) 
      case string: 
       v_conv = v3.(string) 
      case float64: 
       v_conv = strconv.FormatFloat(v3.(float64), 'f', 0, 64) 
      default: 
       fmt.Println("vtype unknown: ", v_type) //have to use v_type since it is declared 
       v_conv = "" 
      } 
      data_map[k3] = v_conv //append a new map key/value pair both as strings 
      fmt.Println("data_map: ", data_map) 
     } 
     data_final = append(data_final, data_map) // after each cycle through the loop append the map to the new list 
     fmt.Println("data_final: ", data_final) 
    } 
} 
}
