先上接口

using System; using System.Collections.Generic; using UnityEngine;namespace YDB.Http {public interface IHttp{/// <summary>/// Get/// </summary>/// <param name="callback">回調</param>/// <param name="url">地址</param>void Get(Action<string> callback,string url);/// <summary>/// Get/// </summary>/// <param name="callback">回調</param>/// <param name="url">地址</param>void Get(Action<byte[]> callback, string url);/// <summary>/// Get/// </summary>/// <param name="callback">回調</param>/// <param name="url">地址</param>void Get(Action<Texture> callback, string url);/// <summary>/// Post/// </summary>/// <param name="parameters">參數</param>/// <param name="url">地址</param>void Post(Dictionary<string, string> parameters, string url);} }

接口具體實現

using System; using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.Networking;namespace YDB.Http {public class Http : MonoBehaviour,IHttp{public void Get(Action<string> callback, string url){if(callback == null){Debug.LogWarning("回調為空，請求了也沒屁用");}UnityWebRequest unityWebRequest = UnityWebRequest.Get(url);StartCoroutine(StartGet(callback,unityWebRequest));}public void Get(Action<byte[]> callback, string url){if (callback == null){Debug.LogWarning("回調為空，請求了也沒屁用");}UnityWebRequest unityWebRequest = UnityWebRequest.Get(url);StartCoroutine(StartGet(callback, unityWebRequest));}public void Get(Action<Texture> callback, string url){if (callback == null){Debug.LogWarning("回調為空，請求了也沒屁用");}UnityWebRequest unityWebRequest = UnityWebRequest.Get(url);DownloadHandlerTexture downloadHandler = new DownloadHandlerTexture();unityWebRequest.downloadHandler = downloadHandler;StartCoroutine(StartGet(callback, unityWebRequest));}public void Post(Dictionary<string, string> parameters, string url){UnityWebRequest unityWebRequest = UnityWebRequest.Post(url, parameters);StartCoroutine(StartPost(unityWebRequest));}private IEnumerator StartPost(UnityWebRequest uwr){yield return uwr.SendWebRequest();if (uwr.isHttpError || uwr.isNetworkError){Debug.LogError(uwr.error);}else{Debug.Log("Post請求成功");}}/// <summary>/// 異步網絡請求/// </summary>/// <typeparam name="T">回調類型</typeparam>/// <param name="callback">回調</param>/// <param name="uwr">請求參數</param>/// <returns></returns>private IEnumerator StartGet<T>(Action<T> callback, UnityWebRequest uwr) where T : class{yield return uwr.SendWebRequest();if (uwr.isHttpError || uwr.isNetworkError){Debug.LogError(uwr.error);}else{Debug.Log("Get請求成功");Type type = typeof(T);if (type == typeof(string)){string text = uwr.downloadHandler.text;callback(text as T);}else if (type == typeof(byte[])){byte[] packet = uwr.downloadHandler.data;callback(packet as T);}else if (type == typeof(Texture)){//特殊的文件類型，通過不同的Handler來下載DownloadHandlerTexture downloadHandler = uwr.downloadHandler as DownloadHandlerTexture;Texture texture = downloadHandler.texture;callback(texture as T);}}}} }
