{"returnCode":3002,"returnMessage":"Request method 'GET' not supported","data":"Request method 'GET' not supported"}什么原因

这个错误通常是由于你向服务器发送了一个不支持的HTTP请求方法，例如使用GET请求访问只支持POST请求的接口。

在这个错误信息中，"Request method 'GET' not supported"表示服务器不支持GET请求方法，而"returnCode":3002则表示你的请求被服务器拒绝了。

要解决这个问题，你需要检查你的代码，确保你正在使用正确的HTTP请求方法，并且检查接口文档或向服务端开发人员咨询，以确定支持的请求方法。

如果你使用的是UnityWebRequest，你可以使用Post或Put等方法来发送POST或PUT请求，例如：

UnityWebRequest request = UnityWebRequest.Post(url, postData);

其中，url是你要访问的接口地址，postData是你要发送的数据。你需要根据接口要求，将数据转换为相应的格式，并将其作为postData参数传递给UnityWebRequest。

如果你仍然遇到问题，请检查接口文档或与服务端开发人员联系，以获取更多帮助。

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); } } }修改代码

根据你提供的代码，可能会有以下几个问题：

1. 在 `UnityWebRequest` 类的构造函数中，第一个参数应该是请求的 URL 地址，而不是字符串 `"POST"`。你需要将 `url` 变量作为第一个参数传递给构造函数。

2. 在 `UnityWebRequest` 类的构造函数中，第二个参数应该是请求的 HTTP 方法，即 `"POST"` 或 `"GET"` 等。由于你的请求是 POST 请求，因此你需要将字符串 `"POST"` 作为第二个参数传递给构造函数。

3. 在发送请求之前，你需要设置请求的超时时间。可以使用 `request.timeout` 属性来设置超时时间，单位为秒。

4. 在请求头中，你设置了 `Content-Type` 为 `"application/json"`。如果你的请求数据不是 JSON 格式，那么你需要将 `Content-Type` 设置为相应的类型，例如 `"application/x-www-form-urlencoded"`。

下面是修改后的代码：

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");
        request.timeout = 10;  // Set request timeout to 10 seconds
        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);
        }
    }
}

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);
}
}
}
