Java 接口代码已经在上一个问题中给出，这里提供 Unity WebGL 的代码实现：

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

public class GetData : MonoBehaviour {
    public Text resultText;

    IEnumerator Start() {
        // 定义接口地址
        string url = "http://158.58.50.21:8886/view/queryFaultAndSubhealthInfo";

        // 构造请求参数
        Dictionary<string, object> requestData = new Dictionary<string, object>();
        requestData["lineid"] = 27;
        requestData["areaid"] = 22;
        requestData["starttime"] = "2023-05-07 09:54:22";
        requestData["endtime"] = "2023-06-07 09:54:22";
        requestData["datatype"] = 2;
        requestData["pageSize"] = 5;
        requestData["pageNumber"] = 1;
        string json = JsonMapper.ToJson(requestData);

        // 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.isNetworkError) {
            Debug.Log(request.error);
            resultText.text = request.error;
        } else {
            // 解析返回的 JSON 数据
            JsonData jsonData = JsonMapper.ToObject(request.downloadHandler.text);

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

这里使用了 `Dictionary<string, object>` 来构造请求参数，并使用 `JsonMapper.ToJson` 方法将其转换为 JSON 格式的字符串。同时，需要注意在判断请求是否出错时，使用的是 `request.isNetworkError` 而不是 `request.isError`。
