當(dāng)我在轉(zhuǎn)換“Id”不正確后將 [] 字節(jié)解組為結(jié)構(gòu)時，我遇到了 json 問題編號：1606146401088049402 => 1606146401088049400`{"status":200,"success":true,"data":{"id":1606146401088049402,"created_at":"2020-11-23T22:46:41.092+07:00","updated_at":"2020-11-23T22:46:41.092+07:00","role":[{"code":"admin","name":"admin"}],"userName":"","phone":"0385666301","email":"congnguyen008@gmail.com","name":"","gender":"","title":"","firstName":"Nguyên","lastName":"Nguy?n","fullName":"Nguyên Nguy?n","displayName":"Nguyên Nguy?n","company":"","department":"","photo":"0385666301","addresses":"","phoneNumber":"","active":true,"lastTimeLogin":"2020-12-23T09:27:30.72+07:00","logged":{"token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MDg2OTQwNTAsImlkIjoiMTYwNjE0NjQwMTA4ODA0OTQwMiIsIm5hbWUiOiJOZ3V5w6puIE5ndXnhu4VuIiwicm9sZSI6W3siY29kZSI6ImFkbWluIiwibmFtZSI6ImFkbWluIn1dfQ.Spj_wWPxRrs2tYYhCmNCWaZVWVack74k9ab1FpeQsf8","time_login":"2020-12-23 09:27:30.720385 +0700 +07 m=+56.589410521","refresh_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MDkyOTUyNTAsImlkIjoiMTYwNjE0NjQwMTA4ODA0OTQwMiIsIm5hbWUiOiJOZ3V5w6puIE5ndXnhu4VuIiwicm9sZSI6W3siY29kZSI6ImFkbWluIiwibmFtZSI6ImFkbWluIn1dfQ.mO08BTq9SUns7OPCOrDeUbZojYkw3tjUaMeIQ_e2e2U"}}}`代碼https://play.golang.org/p/MKmkLGPfwFafunc main() { jsonData := `{"status":200,"success":true,"data":{"id":1606146401088049402}}` response := Response{} err := json.Unmarshal([]byte(jsonData), &response) if err != nil { panic(err) } user := User{} userJson, _ := json.Marshal(response.Data) json.Unmarshal(userJson, &user) fmt.Println(user.Id) fmt.Printf("%T", user.Id)}type User struct { Id int64 `json:"id" gorm:"primarykey"` UserName string `json:"userName"`}

如果你想推遲 json 處理.. 而不是使用接口，編組然后解組，你可以使用json.RawMessage，像這樣：
https://play.golang.org/p/LR1OXWpk_sF
這消除了Marshal操作和錯誤類型轉(zhuǎn)換的問題。

要將 JSON 解組為接口值，Unmarshal 將其中之一存儲在接口值中：float64，用于 JSON 數(shù)字
float64 類型產(chǎn)生錯誤的解組。
https://golang.org/pkg/encoding/json/#Unmarshal
type Response struct {
Status int `json:"status"`
Success bool `json:"success"`
Data Datam `json:"data,omitempty"`
Message string `json:"message,omitempty"`
Input interface{} `json:"input,omitempty"`
Error error `json:"error,omitempty"`
Paging interface{} `json:"paging,omitempty"`
}
type Datam struct{
Id int64 `json:"id"`
}
正確解組給定的 id。
