Question

我正在使用unity3d，我有一个JSON对象。我可以使用ob.name等访问每个成员，但我希望在运行时将这个反序列化的块打印在我的屏幕上。与搜索结果类似，所以我得到了搜索结果的JSON我想在我的屏幕上显示它。我得到错误，我无法打印对象，因为我使用（ob.name）toString（）; 我不知道如何在屏幕上的运行时间显示它。

ObjR rs = JsonUtility.FromJson<ObjR>(jsonString);
//so now I want to print to screen each element of rs.How do I do that during runtime.

编辑：我能在Debug.Log上看到，我只需要在屏幕上动态打印它们。请注意，结果的大小或数量在运行时会有所不同。任何帮助都是值得赞赏的。所以我发现这个现在我在屏幕上看到它。 http://wiki.unity3d.com/index.php/DebugConsole.Can任何人都可以帮助我们如何回复点击事件？

var client = new RestClient(Url);
var req = new RestRequest(UrlEndpoint, Method.GET)
            .AddParameter("apikey", apiKey)
            .AddParameter("q", query)

    // Perform the search and obtain results
var resp = client.Execute(req);
var search = JsonConvert.DeserializeObject<dynamic>(resp.Content);

// Print the number of results
Console.WriteLine("Number of hits: " + search["hits"]);
Debug.Log(search["hits"] + " ");
foreach (var result in search["results"])
{
    var part = result["item"];
    // want to print to screen each item and mpn
    //Debug.Log(part["brand"]["name"] + " " + part["mpn"]);
    //what i tried/ string hits = search["hits"].ToString();//error

    //expected type object and found string
    GUILabel(float,float,needed string here);
}

Answer 1

如果你想用这个json做一些调试输出 - 使用GUI.Label会更容易。它易于设置，您可以根据字符串中的行数或字符数管理标签的大小。但由于性能不佳，它绝对不适合生产。

另一种简单的方法是创建Unity UI Canvas并添加一个带有Text元素的Panel。 Text元素具有Best Fit属性，允许您为标签设置最小和最大字体大小。因此，将自动计算字体的大小，以使文本适合Text元素的大小。要在Text元素上接收单击事件，您还可以添加Button元素。

问题在于，当您使用var search = JsonConvert.DeserializeObject<dynamic>(resp.Content);时，您不会将其反序列化为特定的对象，并且很难打印您的json。

如果您知道Json的外观，请使用this将其转换为可以轻松用于在屏幕上显示Json的对象。请注意，您必须删除{ get; set; }并将[Serializable]添加到每个生成的类的顶部，如here所述。

使用这些生成的类，您可以将收到的Json转换为Object

//Convert Json to Object so that we can print it
string yourJsonFromServer = resp.Content;//Replace with Json from the server
RootObject rootObj = JsonUtility.FromJson<RootObject>(yourJsonFromServer);

现在，连接您需要显示的所有字符串。

string dispStr;
dispStr = "__class__: " + rootObj.__class__ + "\r\n";
dispStr = dispStr + "mpn:" + rootObj.mpn + "\r\n";
dispStr = dispStr + "uid:" + rootObj.uid + "\r\n";

//manufacturer info
dispStr = "Manufacturer __class__: " + rootObj.manufacturer.__class__ + "\r\n";
dispStr = "Manufacturer homepage_url: " + rootObj.manufacturer.homepage_url + "\r\n";
dispStr = "Manufacturer name: " + rootObj.manufacturer.name + "\r\n";
dispStr = "Manufacturer uid: " + rootObj.manufacturer.uid + "\r\n";

最后，使用Text组件显示它们。一个Text组件就足够了。只需使用＆＃34; \r\n＆＃34;将它们分开：

public Text infoText;
...
infoText.horizontalOverflow = HorizontalWrapMode.Overflow;
infoText.verticalOverflow = VerticalWrapMode.Overflow;
infoText.text = dispStr;

对于List或Array项，您可以使用for循环覆盖并显示它们。

string dispStr = "";
for (int i = 0; i < rootObj.offers.Count; i++)
{
    dispStr = dispStr + "SKU: " + rootObj.offers[i].sku + "\r\n";
    dispStr = dispStr + "REGION: " + rootObj.offers[i].eligible_region + "\r\n\r\n\r\n";
}
infoText.text = dispStr;

完整示例：

public Text infoText;

void Start()
{
    //Convert Json to Object so that we can print it
    string yourJsonFromServer = resp.Content;//Replace with Json from the server
    RootObject rootObj = JsonUtility.FromJson<RootObject>(yourJsonFromServer);

    string dispStr;

    dispStr = "__class__: " + rootObj.__class__ + "\r\n";
    dispStr = dispStr + "mpn:" + rootObj.mpn + "\r\n";
    dispStr = dispStr + "uid:" + rootObj.uid + "\r\n";

    //Example, Show manufacturer info
    dispStr = "Manufacturer __class__: " + rootObj.manufacturer.__class__ + "\r\n";
    dispStr = "Manufacturer homepage_url: " + rootObj.manufacturer.homepage_url + "\r\n";
    dispStr = "Manufacturer name: " + rootObj.manufacturer.name + "\r\n";
    dispStr = "Manufacturer uid: " + rootObj.manufacturer.uid + "\r\n";

    //Display
    infoText.horizontalOverflow = HorizontalWrapMode.Overflow;
    infoText.verticalOverflow = VerticalWrapMode.Overflow;
    infoText.text = dispStr;
}
