綁定JSON對象數組中Angular2查看nativescript

Question

我有一個JSON對象從我的API返回這樣

{ 
"ID": "GM5VY", 
"Passengers": [ 
{ 
"Firstname": "TEST", 
"Lastname": "TRAVELLER", 
"TotalCount": "1", 
FqtT": [ 
    { 
    "MembershipID": "XXXXXX" 
    } 
], 
"Errors": null, 
"Information": null, 
"Warnings": null 
} 
], 
"Errors": null, 
"Information": null, 
"Warnings": null 
} 

我使用管道過濾器此對象轉換爲一個數組，並試圖顯示乘客名字在視圖。但我無法檢索

<StackLayout *ngFor=" let passengerls of PassengerDetails | objtoarray; let i = index"> 
    <Label [text]="passengerls?.value?.Passengers ? passengerls?.value?.Passengers[i].Firstname:null"> </Label>       

</StackLayout> 

請幫我達到這個!!!

如何用簡單的方法來遍歷數組：

<StackLayout *ngFor="let passenger of PassengerDetails.Passengers"> 
    <Label [text]="passenger.Firstname"></Label> 
</StackLayout>
