Question

我收到一个JSON以响应请求。我能够访问简单的变量并在屏幕上打印它们。但我不知道如何访问深度变量并在屏幕上打印它。我想访问里面的变量“提供“课程。我怎么去做？这是我的模特课。

        }
    }
    private const string APIKEY = "57af648b";

}

我的Json太大了，无法在此发布，所以这里有一个链接：https://octopart.com/api/docs/v3/search-tutorial

Answer 1

只是为了将来参考，您可以通过查看首先声明Offer的位置然后从那里下载来找到它。

1 。Offer类在 Item 类中声明为public List<Offer> offers;。

2 。Item类在 Result 类中声明为public Item item;。

3 。最后，Result类在 RootOb 类中声明为公共List<Result> results;。

找到后，您可以通过反转来访问Offer课程。从＃3 开始，回到＃1 。

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

<强>＃3 即可。List<Result> result = rr.results;

<强>＃2 即可。 Item item = result[0].item;

可以有多个Result，因为它是List。在访问之前，您可以使用result.Count检查Item的数量。{/ p>

Item item1 = result[0].item;

Item item2 = result[1].item;

Item item3 = result[2].item;

<强>＃1 即可。Offer offer = item.offers[0];

可以有多个Offer，因为它是List。您可以使用item.offers.Count检查访问前的数量。

Offer offer1 = item.offers[0];

Offer offer2 = item.offers[1];

Offer offer3 = item.offers[2];

同样，就是这样：

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

最后，最好用for循环完成：

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);
    }
}
