小编给大家分享一下Unity3D网络通讯中HttpRestful请求如何封装，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
我们在Scripts下建了一个Model的文件夹（存放对象类）和一个Utils的文件夹（存放工具类），然后把WeatherForecase类移动到Model下，在Utils文件夹下再创建一个Network的文件夹，用于处理网络通讯，然后在这文件夹下创建一个HttpRestful的C#脚本。
写Get的协程方法调用，其中最后一个参数就是Action<bool, string>的方法，其中Action的第一个参数bool，用于返回通讯的成功或失败，第二个参数string是返回的通讯信息。
外部调用的Get方法传入的参数一样，内部是直接开户协程操作，下面的Post的实现也是按这个思路来写，只不过传入的参数里要加入一个我们传入的数据即可。
using System;using System.Collections;using System.Collections.Generic;using System.Text;using UnityEngine;using UnityEngine.Networking;
public class HttpRestful : MonoBehaviour{ private static HttpRestful _instance;
public static HttpRestful Instance { get { if(_instance == null) { GameObject goRestful = new GameObject("HttpRestful"); _instance = goRestful.AddComponent<HttpRestful>(); } return _instance; } }
#region Get请求 /// <summary> /// Get请求 /// </summary> /// <param name="url"></param> /// <param name="actionResult"></param> public void Get(string url, Action<bool, string> actionResult = null) { StartCoroutine(_Get(url, actionResult)); }
private IEnumerator _Get(string url, Action<bool, string> action) { using (UnityWebRequest request = UnityWebRequest.Get(url)) { yield return request.SendWebRequest();
string resstr = ""; if (request.isNetworkError || request.isHttpError) { resstr = request.error; } else { resstr = request.downloadHandler.text; }
if (action != null) { action(request.isHttpError, resstr); } } } #endregion
#region POST请求 public void Post(string url, string data, Action<bool, string> actionResult = null) { StartCoroutine(_Post(url, data, actionResult)); }
private IEnumerator _Post(string url, string data, Action<bool, string> action) { using (UnityWebRequest request = new UnityWebRequest(url, "POST")) { request.uploadHandler = new UploadHandlerRaw(Encoding.UTF8.GetBytes(data)); request.SetRequestHeader("content-type", "application/json;charset=utf-8"); request.downloadHandler = new DownloadHandlerBuffer();
yield return request.SendWebRequest();
string resstr = ""; if (request.isNetworkError || request.isHttpError) { resstr = request.error; } else { resstr = request.downloadHandler.text; }
if (action != null) { action(request.isHttpError, resstr); } } } #endregion}
我们重新复制了一个UIScripts，然后其中一个名字后面加上了Old，这样就是不用再重新设置了，我们直接在UIScripts脚本中改造即可。
首先定义一个Action<bool, string>，其中参数和HttpRestful里传入的Action方法是一样的。
然后增加一个InitAction的方法，里面对定义的actionRes写其的实现方法。方法中就是判断通讯如果失败直接显示文本，成功后进行处理，再显示处理后的数据，因为Get和Post调用后返回的数据类型是一样的，这样我们这里写了一个Action都可以调用这个方法进行后面的数据处理。
然后我们在Start里面首先把初始化Action进行调用，然后使用
HttpRestful.Instance.Get(url, actionRes);HttpRestful.Instance.Post(url, json, actionRes);
就可以直接进行数据处理了，剩下的我们昨天调用的方法就可以都删除了。
using System;using System.Collections;using System.Collections.Generic;using System.ComponentModel;using System.Linq;using System.Text;using UnityEngine;using UnityEngine.Networking;using UnityEngine.UI;
public class UIScripts : MonoBehaviour{ [Header("按钮")] public Button btnget; public Button btngetparm; public Button btnjson; public Button btnpost;
[Space] [Header("显示")] public Text txtshow;
[Space] [Header("输入框")] public InputField edturl; public InputField edtparm;
//定义一个返回数据的Action private Action<bool, string> actionRes; // Start is called before the first frame update void Start() { InitAction();
//Get按钮操作 btnget.onClick.AddListener(() => { Debug.Log(edturl.text); string url = edturl.text; HttpRestful.Instance.Get(url, actionRes); }); btngetparm.onClick.AddListener(() => { string url = edturl.text; string param = edtparm.text;
string allurl = url + "/Info?Summary=" + param; HttpRestful.Instance.Get(allurl, actionRes); });
btnjson.onClick.AddListener(() => StartCoroutine(JsonConvert()));
btnpost.onClick.AddListener(() => { WeatherForecast item = new WeatherForecast(); item.Summary = "Alvin"; item.Date = DateTime.Now; item.TemperatureC = 10; item.TemperatureF = 20; string json = JsonUtility.ToJson(item);
string url = edturl.text + "/Reg"; Debug.Log(url); HttpRestful.Instance.Post(url, json, actionRes); }); }
/// <summary> /// 写返回Action的处理方法 /// </summary> private void InitAction() { actionRes = new Action<bool, string>((bl, str) => { if (bl) { txtshow.text = str; } else { string resjson = "{\"array\":" + str + "}"; txtshow.text = resjson; WeatherData lists = JsonUtility.FromJson<WeatherData>(resjson); StringBuilder sb = new StringBuilder(); foreach (WeatherForecast item in lists.array) { sb.Append("Date:" + item.Date + " Summary:" + item.Summary + " TemperatureF:" + item.TemperatureF + "TemperatureC:" + item.TemperatureC + "\r\n"); } txtshow.text = sb.ToString(); } }); }
IEnumerator JsonConvert() { WeatherForecast item = new WeatherForecast(); item.Summary = "Alvin"; item.Date = DateTime.Now; item.TemperatureC = 10; item.TemperatureF = 20;
string json = JsonUtility.ToJson(item); txtshow.text = json; yield return new WaitForSeconds(3f);
WeatherForecast newitem = JsonUtility.FromJson<WeatherForecast>(json); string showtext = "Summary:" + newitem.Summary + " Date:" + newitem.Date + " C:" + newitem.TemperatureC + " F:" + newitem.TemperatureF; txtshow.text = showtext; }}
上图就是封装后调用WebApi的实现效果，后面我又在Android平台下进行了编译，调用也完全没有问题，这种方式可以跨平台使用的。 看完了这篇文章，相信你对“Unity3D网络通讯中HttpRestful请求如何封装”有了一定的了解，如果想了解更多相关知识，欢迎关注天达云行业资讯频道，感谢各位的阅读！
