我有一個(gè) JSON 對(duì)象數(shù)組，作為結(jié)構(gòu)：type Data struct { TaiList []Tai `json:"taiList"`}type Tai struct { PlmnId *PlmnId `json:"plmnId"` Tac string `json:"tac"` Nid string `json:"nid"`}type PlmnId struct { Mcc string `json:"mcc"` Mnc string `json:"mnc"`}蒙哥德百科中的 JSON 的格式為[{ "taiList": [ { "plmnId": { "mcc": "244", "mnc": "24" }, "tac": "00001", "nid": "99" }, { "plmnId": { "mcc": "244", "mnc": "34" }, "tac": "00001", "nid": "555" } ]}, { "taiList": [ { "plmnId": { "mcc": "244", "mnc": "24" }, "tac": "00001", "nid": "99" } ]}]JSON “taiList”是在從 mongodb 取消封口后形成的，有意省略了錯(cuò)誤檢查。func MongoFind(id string) (Data, error) { filter := bson.M{"_id": id} var ( result model.Data ) ... DB.Collection(tailistCollection).FindOne(context.TODO(),filter).Decode(&result) ... return result, nil}蒙戈查找返回?cái)?shù)據(jù)和錯(cuò)誤。數(shù)據(jù).TaiList數(shù)組是我想執(zhí)行檢查的。我想檢查JSON對(duì)象“ta”是否包含在“taiList”中。 var ta = model.Tai{ PlmnId: &model.PlmnId{Mcc: "244", Mnc: "34"}, Tac: "00001", Nid: "555",}我嘗試了下面的代碼var data Datafunc CheckTai(ta models.Tai, data Data) bool { for _, Tai := range data.TaiList { if reflect.DeepEqual(Tai, ta) { return true } } return false}但檢查泰函數(shù)返回錯(cuò)誤。僅當(dāng)只有一個(gè) JSON 對(duì)象與列表匹配時(shí)，檢查泰才會(huì)返回 true{ "taiList": [ { "plmnId": { "mcc": "244", "mnc": "24" }, "tac": "00001", "nid": "555" } ] }需要幫助或想法如何執(zhí)行此檢查。

根據(jù)評(píng)論中的建議，我復(fù)制了您的方案，如下所示：
package main
import (
"encoding/json"
"fmt"
"log"
"reflect"
)
type Data struct {
TaiList []Tai `json:"taiList"`
}
type Tai struct {
PlmnId *PlmnId `json:"plmnId"`
Tac string `json:"tac"`
Nid string `json:"nid"`
}
type PlmnId struct {
Mcc string `json:"mcc"`
Mnc string `json:"mnc"`
}
var data = []byte(`{
"taiList": [
{
"plmnId": {
"mcc": "244",
"mnc": "24"
},
"tac": "00001",
"nid": "99"
},
{
"plmnId": {
"mcc": "244",
"mnc": "34"
},
"tac": "00001",
"nid": "555"
}
]
}
`)
var ta = Tai{
PlmnId: &PlmnId{Mcc: "244", Mnc: "34"},
Tac: "00001",
Nid: "555",
}
func CheckTai(ta Tai, data Data) bool {
for _, Tai := range data.TaiList {
if reflect.DeepEqual(Tai, ta) {
return true
}
}
return false
}
func main() {
var v Data
err := json.Unmarshal(data, &v)
if err != nil {
log.Fatal(err)
}
fmt.Println(CheckTai(ta, v))
}
輸出：
true
