无法将当前 JSON 对象（例如 {"name":"value"}）反序列化为类型 'Value[]'，因为该类型需要一个 JSON 数组（例如 [1,2 ,3])
Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'Value[]' because the type requires a JSON array (e.g. [1,2,3])
我正在为这个例外而苦恼。
我正在尝试从 json 文件中获取一些信息并从中获取一些 C# 对象。但是由于某些原因，Unity不允许我反序列化它。
这是我的 C# 代码：
IEnumerator SendRequest(string urlParam, Action<UnityWebRequest> callback)
{
using (webRequest = UnityWebRequest.Get(urlParam))
{
yield return webRequest.SendWebRequest();
callback(webRequest);
if (webRequest.isNetworkError || webRequest.isHttpError)
Debug.LogError(webRequest.error);
//else Debug.Log("Command has been performed successfully");
}
}
public void StartTestSuite2()
{
StartCoroutine(SendRequest("http://localhost:8086/down|PopOut1", (UnityWebRequest req) =>
{
if (req.isNetworkError || req.isHttpError)
{
Debug.Log($"{req.error}: {req.downloadHandler.text}");
}
else
{
Value[] values = JsonConvert.DeserializeObject<Value[]>(req.downloadHandler.text);
foreach (Value value in values)
{
Debug.Log(value.x);
}
}
}));
}
我已经在谷歌上搜索过了，发现有些人遇到了同样的问题，但我不知道如何解决我的问题。
我试过反序列化 Value 而不是 Value[]，它确实有效。
但是我无法通过 foreach（我需要）table
有人可以帮我吗？
谢谢，

现在您已经发布了 JSON 的其余部分，我可以看到您正在尝试访问一个包含在更大的 JSON 对象中的内部数组。
代码本身 "worked" 有一个 Value 因为你有一个 JSON 对象，没有数组！
但是，它不会有任何字段与 JSON 字符串中的条目相匹配，因此无论如何它们都会有它们的默认值。
因此，您实际上应该拥有的是包含 JSON
相关字段的包装器 class
[Serializable]
public class JsonRoot
{
public string scene;
public Value[] gameObjectDefinitions;
}
然后反序列化成这个类型
var jsonRoot = JsonConverter.Deserialize<JsonRoot>(req.downloadHandler.text);
现在您可以访问和迭代
foreach(var value in jsonRoot.gameObjectDefinitions)
{
...
}
此处的替代方法可能是使用 SimpleJson
var jsonRoot = JSON.Parse(req.downloadHandler.text);
var values = jsonRoot["gameObjectDefinitions"].AsArray;
关于您对 children 的评论：
您会在 Value class 中发现它们根本不存在，因此目前无法访问它们。
如果你想表示完整的 JSON 格式，你的 classes 应该看起来像
[Serializable]
public class JsonRoot
{
public string scene;
public Value[] gameObjectDefinitions;
public string[] buttons;
}
[Serializable]
public class Value
{
public string name;
public string type;
public float x;
public float y;
public int instanceID;
public string[] buttons;
public Value[] children;
}
注意：Unity 将此类递归类型结构的序列化限制为最大嵌套层数 7！我不知道您使用的 JSON 库如何处理此问题，但请注意可能存在此限制。
我不知道您的最终目标是什么，但我想迭代所有子项和子项的唯一方法确实是递归方法，例如
...
foreach(var value in jsonRoot.gameObjectDefinitions)
{
HandleValue(value);
}
...
private void HandleValue(Value value)
{
...
if(value.children != null)
{
foreach(var child in value.children)
{
HandleValue(child);
}
}
}

这是我的 C# 代码：
IEnumerator SendRequest(string urlParam, Action<UnityWebRequest> callback)

}
else

现在您已经发布了 JSON 的其余部分，我可以看到您正在尝试访问一个包含在更大的 JSON 对象中的内部数组。
代码本身 "worked" 有一个 Value 因为你有一个 JSON 对象，没有数组！
但是，它不会有任何字段与 JSON 字符串中的条目相匹配，因此无论如何它们都会有它们的默认值。
因此，您实际上应该拥有的是包含 JSON
相关字段的包装器 class[Serializable]
public class JsonRoot
{
public string scene;
public Value[] gameObjectDefinitions;
}
然后反序列化成这个类型
var jsonRoot = JsonConverter.Deserialize<JsonRoot>(req.downloadHandler.text);
现在您可以访问和迭代
foreach(var value in jsonRoot.gameObjectDefinitions)
{
...
}
此处的替代方法可能是使用 SimpleJson
var jsonRoot = JSON.Parse(req.downloadHandler.text);
var values = jsonRoot["gameObjectDefinitions"].AsArray;
关于您对 children 的评论：
您会在 Value class 中发现它们根本不存在，因此目前无法访问它们。
如果你想表示完整的 JSON 格式，你的 classes 应该看起来像
[Serializable]
public class JsonRoot
{
public string scene;
public Value[] gameObjectDefinitions;
public string[] buttons;
}
[Serializable]
public class Value
{
public string name;
public string type;
public float x;
public float y;
public int instanceID;
public string[] buttons;
public Value[] children;
}
注意：Unity 将此类递归类型结构的序列化限制为最大嵌套层数 7！我不知道您使用的 JSON 库如何处理此问题，但请注意可能存在此限制。
我不知道您的最终目标是什么，但我想迭代所有子项和子项的唯一方法确实是递归方法，例如
...
foreach(var value in jsonRoot.gameObjectDefinitions)
{
HandleValue(value);
}
...
private void HandleValue(Value value)
{
...
if(value.children != null)
{
foreach(var child in value.children)
{
HandleValue(child);
}
}
}
