當我獲得新的數(shù)據(jù) json ORDER_TRX_H_ID 時，結果必須使用新的 ORDER_TRX_H_ID 循環(huán)，但我的結果始終顯示最后的數(shù)據(jù)。我的代碼是package mainimport ( "encoding/json" "fmt")func main() { dataJSON := `[{ "QUICK_DATA_H_ID": "1", "ORDER_TRX_H_ID": "1", "FIELD_QUESTION": "FULLNAME", "FIELD_ANSWER": "RUBEN", "DTM_CRT": "2019-08-28T16:25:15.757Z"},{ "QUICK_DATA_H_ID": "2", "ORDER_TRX_H_ID": "1", "FIELD_QUESTION": "ALAMAT_KTP", "FIELD_ANSWER": "jalandisana", "DTM_CRT": "2019-08-28T16:25:15.757Z"},{ "QUICK_DATA_H_ID": "3", "ORDER_TRX_H_ID": "2", "FIELD_QUESTION": "FULLNAME", "FIELD_ANSWER": "Fariz", "DTM_CRT": "2019-08-28T16:25:15.757Z"},{ "QUICK_DATA_H_ID": "4", "ORDER_TRX_H_ID": "2", "FIELD_QUESTION": "ALAMAT_KTP", "FIELD_ANSWER": "Bogor", "DTM_CRT": "2019-08-28T16:25:15.757Z"} ]` var data []map[string]interface{} json.Unmarshal([]byte(dataJSON), &data) qa := map[string]interface{}{} for _, v := range data { qa[v["FIELD_QUESTION"].(string)] = v["FIELD_ANSWER"] } hasil := data[0] hasil["QUESTION"] = qa delete(hasil, "FIELD_QUESTION") delete(hasil, "FIELD_ANSWER") hasilJSON, _ := json.MarshalIndent(hasil, "", " ") fmt.Println(string(hasilJSON))}您可以運行我的代碼 https://play.golang.org/p/aHUoYZlEQs4我的結果總是顯示最后的數(shù)據(jù){ "DTM_CRT": "2019-08-28T16:25:15.757Z", "ORDER_TRX_H_ID": "1", "QUESTION": { "ALAMAT_KTP": "Bogor", "FULLNAME": "Fariz" }, "QUICK_DATA_H_ID": "1"}我的預期結果{ "DTM_CRT": "2019-08-28T16:25:15.757Z", "ORDER_TRX_H_ID": "1", "QUESTION": { "ALAMAT_KTP": "jalandisana", "FULLNAME": "RUBEN" }, "QUICK_DATA_H_ID": "1"},{ "DTM_CRT": "2019-08-28T16:25:15.757Z", "ORDER_TRX_H_ID": "2", "QUESTION": { "ALAMAT_KTP": "Bogor", "FULLNAME": "Fariz" }, "QUICK_DATA_H_ID": "2"}

TA貢獻2041條經(jīng)驗 獲得超4個贊
為什么你的結果只顯示1個數(shù)據(jù)？是因為這行代碼：
hasil := data[0]
hasil總是只有一個元素
也qa將只包含這樣的值：
{
"ALAMAT_KTP": "BOGOR",
"FULLNAME": "Fariz"
}
因為每次data迭代，qa[v["FIELD_QUESTION"].(string)]由于v["FIELD_QUESTION"].(string)不唯一，都會被替換，所以在 的第 3 次迭代中data，qa["ALAMAT_KTP]已經(jīng)有值的"jalandisana"被替換為qa["ALAMAT_KTP] = "Bogor"
我在這里修改了您的代碼：https ://play.golang.org/p/Ca4aGPGJwT7
我用2個map[string]map[string]interface{}來容納qa，modified data 然后我將它們合二為一
package main
import (
"encoding/json"
"fmt"
)
func main() {
dataJSON := `[
{
"QUICK_DATA_H_ID": "1",
"ORDER_TRX_H_ID": "1",
"FIELD_QUESTION": "FULLNAME",
"FIELD_ANSWER": "RUBEN",
"DTM_CRT": "2019-08-28T16:25:15.757Z"
},
{
"QUICK_DATA_H_ID": "2",
"ORDER_TRX_H_ID": "1",
"FIELD_QUESTION": "ALAMAT_KTP",
"FIELD_ANSWER": "jalandisana",
"DTM_CRT": "2019-08-28T16:25:15.757Z"
},
{
"QUICK_DATA_H_ID": "3",
"ORDER_TRX_H_ID": "2",
"FIELD_QUESTION": "FULLNAME",
"FIELD_ANSWER": "Fariz",
"DTM_CRT": "2019-08-28T16:25:15.757Z"
},
{
"QUICK_DATA_H_ID": "4",
"ORDER_TRX_H_ID": "2",
"FIELD_QUESTION": "ALAMAT_KTP",
"FIELD_ANSWER": "Bogor",
"DTM_CRT": "2019-08-28T16:25:15.757Z"
}
]`
var data, finalResult []map[string]interface{}
json.Unmarshal([]byte(dataJSON), &data)
qa := map[string]map[string]interface{}{}
res := map[string]map[string]interface{}{}
for _, v := range data {
if qa[v["ORDER_TRX_H_ID"].(string)] == nil {
// initialize the map first if map is nil
qa[v["ORDER_TRX_H_ID"].(string)] = make(map[string]interface{})
}
qa[v["ORDER_TRX_H_ID"].(string)][v["FIELD_QUESTION"].(string)] = v["FIELD_ANSWER"]
delete(v, "FIELD_QUESTION")
delete(v, "FIELD_ANSWER")
// only assign res if res[key] is nil to prevent doubled data
if res[v["ORDER_TRX_H_ID"].(string)] == nil {
res[v["ORDER_TRX_H_ID"].(string)] = v
}
}
// combine qa and res in finalResult
for k, v := range res {
v["QUESTION"] = qa[k]
finalResult = append(finalResult, v)
}
hasilJSON, _ := json.MarshalIndent(finalResult, "", " ")
fmt.Println(string(hasilJSON))
}
輸出：
[
{
"DTM_CRT": "2019-08-28T16:25:15.757Z",
"ORDER_TRX_H_ID": "1",
"QUESTION": {
"ALAMAT_KTP": "jalandisana",
"FULLNAME": "RUBEN"
},
"QUICK_DATA_H_ID": "1"
},
{
"DTM_CRT": "2019-08-28T16:25:15.757Z",
"ORDER_TRX_H_ID": "2",
"QUESTION": {
"ALAMAT_KTP": "Bogor",
"FULLNAME": "Fariz"
},
"QUICK_DATA_H_ID": "3"
}
]
