我有一個(gè)結(jié)構(gòu)，現(xiàn)在想從接收到的 http 數(shù)據(jù)中實(shí)例化它。但是現(xiàn)在自己寫的代碼比較繁瑣，代碼行很多。有什么辦法可以簡(jiǎn)化代碼嗎？除了字段id以外的所有字段都可以對(duì)應(yīng)模型type ALiNotifyLog struct { ID *int `json:"id"` APPId *string `json:"app_id"` AuthAppId *string `json:"auth_app_id"` BuyerId *string `json:"buyer_id"` BuyerPayAmount *string `json:"buyer_pay_amount"` GmtCreate *string `json:"gmt_create"` GmtPayment *string `json:"gmt_payment"` InvoiceAmount *string `json:"invoice_amount"` NotifyId *string `json:"notify_id"` NotifyTime *string `json:"notify_time"` OutTradeNo *string `json:"out_trade_no"` PointAmount *string `json:"point_amount"` ReceiptAmount *string `json:"receipt_amount"` Sign *string `json:"sign"` TotalAmount *string `json:"total_amount"` TradeNo *string `json:"trade_no"` TradeStatus *string `json:"trade_status"`}功能func SaveData(data map[string]interface{}) { app_id := data["app_id"].(string) auth_app_id := data["auth_app_id"].(string) buyer_id := data["buyer_id"].(string) buyer_pay_amount := data["buyer_pay_amount"].(string) gmt_create := data["gmt_create"].(string) gmt_payment := data["gmt_payment"].(string) invoice_amount := data["invoice_amount"].(string) notify_id := data["notify_id"].(string) notify_time := data["notify_time"].(string) out_trade_no := data["out_trade_no"].(string) point_amount := data["point_amount"].(string) receipt_amount := data["receipt_amount"].(string) sign := data["sign"].(string) total_amount := data["total_amount"].(string) trade_no := data["trade_no"].(string) trade_status := data["trade_status"].(string) res := global.Orm.Table(paynotifylog).Create(&model) fmt.Println(res)}

我看到你是JSON?？梢詫?JSON 直接解碼為結(jié)構(gòu)實(shí)例。
我將構(gòu)建類似于以下代碼片段的代碼：
type ALiNotifyLog struct {
// your fields here
}
func parseRequest(r *http.Request) {
var notifyLog ALiNotifyLog
err := json.NewDecoder(r.Body).Decode(¬ifyLog)
if err != nil {
// do something
}
// ............ more code
}
func SaveData(data ALiNotifyLog) {
res := global.Orm.Table(paynotifylog).Create(&data)
fmt.Println(res)
// ........... more code
}

使用來自 GitHub的包mapstructure。
go get https://github.com/mitchellh/mapstructure
package main
import (
"log"
"os"
"github.com/mitchellh/mapstructure"
)
type MyStruct struct {
This int
That string `json:"thaaaaat"`
}
func main() {
var result map[string]interface{}
cfg := &mapstructure.DecoderConfig{
TagName: "json",
Result: &result,
}
decoder, err := mapstructure.NewDecoder(cfg)
if err != nil {
log.Printf("Could not create decoder: %v", err)
os.Exit(1)
}
myData := &MyStruct{
This: 42,
That: "foobar",
}
err = decoder.Decode(myData)
if err != nil {
log.Printf("Decoding failed: %v", err)
os.Exit(1)
}
log.Print(cfg.Result)
}
輸出：
&map[This:42 thaaaaaat:foobar]
