我有一個(gè)工作代碼：data, err := ioutil.ReadFile("D:/Go/Go_project/Go_pro/firstfile.json") if err != nil { fmt.Print(err) } data1, err := ioutil.ReadFile("D:/Go/Go_project/Go_pro/secondfile.json") if err != nil { fmt.Print(err) } var migrations map[string]interface{} var migrations1 map[string]interface{}err = json.Unmarshal([]byte(data), &migrations)err = json.Unmarshal([]byte(data1), &migrations1)if err != nil { log.Println("Error:", err)}layout := "2006-01-02T15:04:05.000Z"t, err := time.Parse(layout, fmt.Sprint(migrations["date"]))t1, err := time.Parse(layout, fmt.Sprint(migrations1["date"]))if err != nil { fmt.Println(err)}firsthour := t.Hour()secondhour := t1.Hour()if firsthour == secondhour { result := make(map[string][]interface{}) for k, v := range migrations { result[k] = append(result[k], v) } for k, v := range migrations1 { result[k] = append(result[k], v) } b, err := json.Marshal(result) if err != nil { fmt.Println(err) } os.Stdout.Write(b)} else { err = json.Unmarshal([]byte(data), &migrations) if err != nil { panic(err) } err = json.Unmarshal([]byte(data1), &migrations1) if err != nil { panic(err) } a, err := json.Marshal(migrations) a2, err := json.Marshal(migrations1) if err != nil { fmt.Println(err) } os.Stdout.Write(a) os.Stdout.Write(a2)最后我得到：{"data":["is nice","is a good person"],"date":["2012-04-23T18:24:59.511Z","2012-04-23T18:25:00.511Z"],"name":["Kate","Gleison"]}我需要如何更改代碼，最終將得到： { "name":["kate","gleison"], "date":"2012-04-23T18:00:00.000Z", "data":["is nice","is a good person"] }這是我的 2 個(gè) json 文件。第一的：{ "name":"Kate", "date":"2012-04-23T18:24:59.511Z", "data":"is nice"}第二：{ "name":"Gleison", "date":"2012-04-23T18:25:00.511Z", "data":"is a good person"}

只是我的猜測（可能有更好的方法）：
聲明result為字符串到接口的映射并date單獨(dú)添加鍵（我將把它的值留給你。我也跳過了else一部分，因?yàn)樗坪跖c問題無關(guān)）：
if firsthour == secondhour {
result := make(map[string]interface{})
result["date"] = "value_of_date"
for k, v := range migrations {
if k != "date" {
if result[k] == nil {
result[k] = make([]string, 0)
}
result[k] = append(result[k].([]string), v.(string))
}
}
for k, v := range migrations1 {
if k != "date" {
if result[k] == nil {
result[k] = make([]string, 0)
}
result[k] = append(result[k].([]string), v.(string))
}
}
b, err := json.Marshal(result)
if err != nil {
fmt.Println(err)
}
fmt.Print(string(b))
} else { ... }
