有沒有辦法遍歷json的所有鍵和值，從而通過匹配的路徑或匹配的比較鍵或值確認和替換特定值，并在用中的鍵新值確認后同時創建一個新的json接口戈朗。這是我看到的一個循環遍歷所有值的示例https://play.golang.org/p/xtiT2iGocBg但我不知道用匹配的路徑或值替換值

我終于成功地獲取了鍵/值，并且現在可以同時替換任何值或鍵，但我現在正在努力的最后一步是如何分別獲取所有值的aMap[key]和路徑。anArray[i]例如 "test2": "TEST EACH REPLACE "有一個路徑outterJSON.innerJSON1.nnerInnerArray.1.test2但可以是任何格式。

var co=""
func main() {
//Creating the maps for JSON
m := map[string]interface{}{}
//Parsing/Unmarshalling JSON encoding/json
err := json.Unmarshal([]byte(input), &m)
if err != nil {
panic(err)
}
parseMap(m)
fmt.Println(co)
data, _ := json.MarshalIndent(m,"", " ")
fmt.Println(string(data))
}
func parseMap(aMap map[string]interface{}) {
for key, val := range aMap {
switch concreteVal := val.(type) {
case map[string]interface{}:
co += key+"."
fmt.Println(key+"NwHN")
parseMap(val.(map[string]interface{}))
case []interface{}:
co += key+"."
fmt.Println(key+"NHN")
parseArray(val.([]interface{}))
default:
fmt.Println("OOOOO")
aMap[key]="TEST EACH REPLACE "
fmt.Println(key, "v:", concreteVal)

最后！我完成了我要找的東西的完整規格?。?/p>
