一个接口，获取返回的数据，并将其中的某些数据显示在 Unity 中的文本框中。接口地址是"http://158.58.50.21:8886/view/queryFaultAndSubhealthInfo"，请求方式是POST，请求参数是一个JSON格式的字符串，包括lineid、areaid、starttime、endtime、datatype、pageSize和pageNumber这些参数。发送请求后，如果返回的数据中有错误，则会将错误信息打印出来并显示在文本框中；否则会将返回的JSON数据解析后，将其中需要的数据显示在文本框中。其中，需要显示在文本框中的数据包括doorno、faultname和happentime这三个字段的值。

这段代码中已经将请求方式改为POST了，可以直接使用。如果你需要看一下使用GET方式的代码，可以参考下面的示例代码：

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() { 
        // 定义接口地址和请求参数 
        string url = "http://158.58.50.21:8886/view/queryFaultAndSubhealthInfo?lineid=27&areaid=22&starttime=2023-05-07 09:54:22&endtime=2023-06-07 09:54:22&datatype=2&pageSize=5&pageNumber=1"; 

        // 构造请求 
        UnityWebRequest request = UnityWebRequest.Get(url); 

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

        // 处理返回结果 
        if (request.isError) { 
            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; 
        } 
    } 
}

使用GET方式时，请求参数是在URL中进行传递的，而不是在请求体中。需要修改的是URL中的参数，将其拼接在URL的后面即可。

using UnityEngine; using UnityEngine.Networking; using System.Collections; using System.Text; using System.Collections.Generic; using LitJson; using UnityEngine.UI; public class Example : MonoBehaviour { public Text responseText; //用于显示Java接口返回的数据的文本框 private const string URL = "http://158.58.50.21:8886/view/queryFaultAndSubhealthInfo"; // 替换成实际的接口地址 IEnumerator Start() { UnityWebRequest request = UnityWebRequest.Get(URL); yield return request.SendWebRequest(); if (!request.isNetworkError && request.responseCode == 200) { string json = request.downloadHandler.text; JsonData jsonData = JsonMapper.ToObject(json); int returnCode = (int)jsonData["returnCode"]; string returnMessage = (string)jsonData["returnMessage"]; if (returnCode == 0) { JsonData data = jsonData["data"]; int total = (int)data["total"]; JsonData list = data["list"]; for (int i = 0; i < list.Count; i++) { int doorid = (int)list[i]["doorid"]; string doorno = (string)list[i]["doorno"]; string faultname = (string)list[i]["faultname"]; // 解析其他字段... Debug.Log("doorid: " + doorid + ", doorno: " + doorno + ", faultname: " + faultname); } } else { Debug.Log("Error: " + returnMessage); Debug.Log("Response: " + request.downloadHandler.text); responseText.text = request.downloadHandler.text; } } else { Debug.Log("Error: " + request.error); } } }接口改为post

可以将代码中的UnityWebRequest.Get(URL)改为UnityWebRequest.Post(URL, ""),并且在Post方法的第二个参数中传入一个空字符串，表示不需要传递任何数据。具体代码如下：

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

public class Example : MonoBehaviour {
public Text responseText; //用于显示Java接口返回的数据的文本框
private const string URL = "http://158.58.50.21:8886/view/queryFaultAndSubhealthInfo"; // 替换成实际的接口地址

IEnumerator Start() {
UnityWebRequest request = UnityWebRequest.Post(URL, "");
yield return request.SendWebRequest();

if (!request.isNetworkError && request.responseCode == 200) {
string json = request.downloadHandler.text;
JsonData jsonData = JsonMapper.ToObject(json);
int returnCode = (int)jsonData["returnCode"];
string returnMessage = (string)jsonData["returnMessage"];

if (returnCode == 0) {
JsonData data = jsonData["data"];
int total = (int)data["total"];
JsonData list = data["list"];

for (int i = 0; i < list.Count; i++) {
int doorid = (int)list[i]["doorid"];
string doorno = (string)list[i]["doorno"];
string faultname = (string)list[i]["faultname"];
// 解析其他字段...
Debug.Log("doorid: " + doorid + ", doorno: " + doorno + ", faultname: " + faultname);
}
} else {
Debug.Log("Error: " + returnMessage);
Debug.Log("Response: " + request.downloadHandler.text);
responseText.text = request.downloadHandler.text;
}
} else {
Debug.Log("Error: " + request.error);
}
}
}
