如何訪問此深度嵌套JSON的變量

Question

我收到一個JSON以響應請求。我可以訪問簡單變量並在屏幕上打印它們。但我不確定如何訪問深層變量並將其打印出來我想要訪問「Offers」類中的變量。我該如何去解決它？ 這是我的模特班。

我的JSON是太大所以張貼在這裏，這裏是一個鏈接：通過查看哪裏Offer首先宣告然後再從下https://octopart.com/api/docs/v3/search-tutorial

Answer 1

只是爲了將來參考，你可以找到這個那裏。

.The Offer類的Item類作爲public List<Offer> offers;內部聲明。

.The Item類的Result類作爲public Item item;內部聲明。

。最後，該Result類的RootOb類公共List<Result> results;內部聲明。

找到後，您可以通過反轉來訪問Offer類。從＃3回到＃1。

---

RootOb rr = JsonUtility.FromJson<RootOb>(octojson); 

＃3。 List<Result> result = rr.results;

＃2。 Item item = result[0].item;

可以有多個Result，因爲它是List。您可以使用result.Count來檢查在訪問它們之前有多少Item。

Item item1 = result[0].item;

Item item2 = result[1].item;

Item item3 = result[2].item;

＃1。 Offer offer = item.offers[0];

可以有多個Offer，因爲它是List。在使用它們之前，您使用item.offers.Count來檢查多少個。

Offer offer1 = item.offers[0];

Offer offer2 = item.offers[1];

Offer offer3 = item.offers[2];

---

再次，它僅僅是這樣的：

RootOb rr = JsonUtility.FromJson<RootOb>(octojson); 
List<Result> result = rr.results; 
Item item = result[0].item; 
Offer offer = item.offers[0]; 

最後，這是最好的一個做了循環：

RootOb rr = JsonUtility.FromJson<RootOb>(octojson); 
List<Result> result = rr.results; 
//Loop through the Results List 
for (int i = 0; i < result.Count; i++) 
{ 
    //Get each item 
    Item item = result[i].item; 
    Debug.Log("Item Index: " + i + "... mpn: " + item.mpn); 

    //Loop through the Offer List 
    for (int j = 0; j < item.offers.Count; j++) 
    { 
     //Get each offer 
     Offer offer = item.offers[j]; 
     Debug.Log("Offer Index: " + j + ".... quantity: " + offer.in_stock_quantity); 
    } 
}
