您可以使用 LitJSON 库对 JSON 字符串进行解析。下面是一个示例代码，假设您已经将上述 JSON 字符串存储在一个名为 response 的字符串变量中：

using LitJson;

// 解析 JSON 字符串
JsonData jsonData = JsonMapper.ToObject(response);

// 获取需要的字段值
string doorNo = jsonData["doorno"].ToString();
string faultInfo = jsonData["faultname"].ToString();
string happenTime = jsonData["happentime"].ToString();

// 输出结果
Debug.Log("车门号：" + doorNo);
Debug.Log("故障信息：" + faultInfo);
Debug.Log("发生时间：" + happenTime);

需要注意的是，上述代码假设您已经正确引入了 LitJSON 库，并且使用了 Unity 引擎的 Debug 类来输出结果。

使用Unity的UnityWebRequest和LitJson库可以很方便地解析JSON数据。以下是示例代码，其中`url`是POST请求的URL地址，`postData`是POST请求的数据。

using UnityEngine;
using UnityEngine.Networking;
using System.Collections;
using System.Collections.Generic;
using LitJson;

public class Example : MonoBehaviour
{
    public UnityEngine.UI.Text resultText;

    void Start()
    {
        StartCoroutine(PostRequest());
    }

    IEnumerator PostRequest()
    {
        string url = "your_post_url_here";
        string postData = "your_post_data_here";

        // Send POST request
        UnityWebRequest request = new UnityWebRequest(url, "POST");
        byte[] bodyRaw = System.Text.Encoding.UTF8.GetBytes(postData);
        request.uploadHandler = new UploadHandlerRaw(bodyRaw);
        request.downloadHandler = new DownloadHandlerBuffer();
        request.SetRequestHeader("Content-Type", "application/json");
        yield return request.SendWebRequest();

        // Parse response
        if (request.result == UnityWebRequest.Result.Success)
        {
            string json = request.downloadHandler.text;
            JsonData data = JsonMapper.ToObject(json);
            string result = "Return Code: " + data["returnCode"] + "\n";
            result += "Return Message: " + data["returnMessage"] + "\n";
            result += "Data: " + data["data"] + "\n";
            resultText.text = result;
        }
        else
        {
            Debug.Log(request.error);
        }
    }
}

注意：在使用LitJson库解析JSON数据之前，需要先将JSON字符串转换为JsonData对象。示例代码中使用的是`JsonMapper.ToObject()`方法。

在 Unity WebGL 中使用 JavaScript 调用接口获取数据，可以参考以下代码：

using System.Collections;
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.UI;

public class GetData : MonoBehaviour
{
    public Text resultText;

    IEnumerator Start()
    {
        // 定义接口地址和请求参数
        string url = "http://your-interface-url.com";
        string json = "{\"lineid\": 27, \"areaid\": 22, \"starttime\": \"2023-05-07 09:54:22\", \"endtime\": \"2023-06-07 09:54:22\", \"datatype\": 1, \"pageSize\": 5, \"pageNumber\": 1 }";

        // 构造请求
        UnityWebRequest request = new UnityWebRequest(url, "POST");
        byte[] bodyRaw = System.Text.Encoding.UTF8.GetBytes(json);
        request.uploadHandler = (UploadHandler)new UploadHandlerRaw(bodyRaw);
        request.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
        request.SetRequestHeader("Content-Type", "application/json");

        // 发送请求
        yield return request.SendWebRequest();

        // 处理返回结果
        if (request.result == UnityWebRequest.Result.ConnectionError || request.result == UnityWebRequest.Result.ProtocolError)
        {
            Debug.Log(request.error);
            resultText.text = request.error;
        }
        else
        {
            // 解析返回的 JSON 数据
            string jsonResult = request.downloadHandler.text;
            JSONObject jsonObject = new JSONObject(jsonResult);

            // 获取需要的数据，将其显示在文本框中
            string text = "";
            foreach (JSONObject item in jsonObject["data"]["list"].list)
            {
                text += item["doorno"].str + " - " + item["faultname"].str + " - " + item["happentime"].str + "\n";
            }
            resultText.text = text;
        }
    }
}

其中，使用 UnityWebRequest 发送 POST 请求，将请求参数放在 JSON 字符串中。解析返回的 JSON 数据，然后遍历需要的数据，将其显示在文本框中。可以根据需要调整显示格式。
