1.网络请求管理器

using LitJson;
using Cysharp.Threading.Tasks;
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.Events;using System.Web;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using UnityEngine.Purchasing.MiniJSON;public class HttpHelper : MonoBehaviour {public static HttpHelper Instance;[DllImport("__Internal")] public static extern string GetUrlParam(string str);private void Awake() {Instance = this;}enum HttpEnum {POST,GET,DEL}UnityWebRequest requestHttp(string url, HttpEnum httpEnum, WWWForm form = null) {if (httpEnum == HttpEnum.GET) {Debug.Log($"url Get:{url}");return UnityWebRequest.Get(url);}else if (httpEnum == HttpEnum.POST) {Debug.Log($"url POST:{url}");return UnityWebRequest.Post(url, form);}else if (httpEnum == HttpEnum.DEL) {Debug.Log($"url Delete:{url}");return UnityWebRequest.Delete(url);}return null;
}}

2.需要引入json数据解析的插件：LitJson

3.POST请求：HttpHelper中添加

public void GetUserInfo(string userId, UnityAction<string, bool> webHttpBack) {StartCoroutine(ccGetUserInfo(userId, webHttpBack));
}IEnumerator ccGetUserInfo(string userId, UnityAction<string, bool> getInfoBack) {var url = Host.ApiHost + "/user/getUsrInfo";WWWForm form = new WWWForm();form.AddField("id", userId);using (UnityWebRequest www = requestHttp(url, HttpEnum.POST, form)) {DownloadHandler downloadHandler = new DownloadHandlerBuffer();www.downloadHandler = downloadHandler;yield return www.SendWebRequest();if (www.result != UnityWebRequest.Result.Success) {Debug.LogError(www.error);}else {Debug.Log($"Form upload complete GetCurSpaceInfo! {www.downloadHandler.text}");JsonData data = JsonMapper.ToObject(www.downloadHandler.text);if (data["data"] != null) {string json = data["data"].ToJson();if (getInfoBack != null) getInfoBack(json, false);}else {if (getInfoBack != null) getInfoBack(null, true);}}}
}

引用路径：

if (HttpHelper.Instance != null) {HttpHelper.Instance.GetUserInfo(PlayerData.Instance.PlayerId.ToString(), getUserInfo);
}public void getUserInfo(string json, bool isNoData)
{json = UtilsFunc.UnicodeToString(json);JsonData data = JsonMapper.ToObject(json);string headUrl = "";if (data.ContainsKey("headImgUrl") && data["headImgUrl"] != null){headUrl = (string)data["headImgUrl"];Debug.Log("头像信息2222222222" + headUrl);StartCoroutine(loadHeadImgUrl(headUrl));}
}

4.GET请求：HttpHelper中添加

public IEnumerator coGetMessBoardList(Action callback, long startDate, long endDate, int page = 1, int limit = 20) {//var url = NetManager.Instance.host + ":":"+port+"/game/space/getSpace";string url = Host.ApiHost + "/message/board/list" + $"?page={page}&limit={limit}&startDate={startDate}&endDate={endDate}&spaceId={PlayerData.Instance.SpaceId}";using (UnityWebRequest www = requestHttp(url, HttpEnum.GET)) {www.SetRequestHeader("Authorization", PlayerData.Instance.ltk);yield return www.SendWebRequest();if (www.result == UnityWebRequest.Result.Success) {string text = www.downloadHandler.text;JsonData data = JsonMapper.ToObject(www.downloadHandler.text);string json = data["data"].ToJson();var listObj = JsonMapper.ToObject<BoardVo>(json);MessageBoardModel.Instance.m_BoardModel.Remove(1); //临时删除1MessageBoardModel.Instance.m_BoardModel.Add(1, listObj);Debug.Log("获取留言列表信息" + text);}else {Debug.LogError(www.error);}}callback.Invoke();
}public void GetMessBoardList(Action callback, long startDate, long endDate, int page = 1, int limit = 20) {StartCoroutine(coGetMessBoardList(callback, startDate, endDate, page, limit));}

引用路径：

HttpHelper.Instance.GetMessBoardList(() =>
{MessageBoardModel.Instance.m_BoardModel.TryGetValue(1, out currentBoard); //这里1是临时的，因为现在留言板就一块if (currentBoard == null){Debug.LogError("OnEnter currentBoard == null");return;}OnRefresh();
}, current, oneMonthLater);

4.DEL请求：HttpHelper中添加

IEnumerator coGetShopUrl(string genUrl, Action<string> callback) {//获取商店链接Debug.Log($"{genUrl}");string url = $"https://api.qrserver.com/v1/create-qr-code/?size=150x150{genUrl}";using (UnityWebRequest www = requestHttp(url, HttpEnum.DEL)) {www.downloadHandler = new DownloadHandlerBuffer();www.SetRequestHeader("Authorization", PlayerData.Instance.ltk);yield return www.SendWebRequest();if (www.result == UnityWebRequest.Result.Success) {Debug.Log("商店链接：" + www.downloadHandler.text);string s = www.downloadHandler.text.Substring(www.downloadHandler.text.IndexOf("<img src=") + 12, www.downloadHandler.text.Length - (www.downloadHandler.text.IndexOf("<img src=") + 12));//截取src="" 内部的链接地址，不包括'//'string result = s.Substring(0, s.IndexOf("\""));callback.Invoke("https://" + result);}else {Debug.LogError(www.error);callback.Invoke(www.error);}}}public void GetShopUrl(string url, Action<string> callback) {StartCoroutine(coGetShopUrl(url, callback));}public void DeleteMessage(Action callback, int id) {StartCoroutine(coDeleteMessage(callback, id));}public IEnumerator coDeleteMessage(Action callback, int id) {string url = Host.ApiHost + "/message/board?id=" + id.ToString();using (UnityWebRequest www = requestHttp(url, HttpEnum.DEL)) {www.downloadHandler = new DownloadHandlerBuffer();www.SetRequestHeader("Authorization", PlayerData.Instance.ltk);yield return www.SendWebRequest();if (www.result == UnityWebRequest.Result.Success) {Debug.Log("删除留言信息" + www.downloadHandler.text);}else {Debug.LogError(www.error);}}callback.Invoke();}

引用路径：

        HttpHelper.Instance.DeleteMessage(() =>{ToastPanel.Show("留言删除成功");currentBoard.records.Remove(delData);OnRefresh();}, delData.id);
