Unity 中的UnityWebRequest使用方法参考

Unity 中的UnityWebRequest使用方法参考

获取AssetBundle：

IEnumerator GetAssetBundle(string path, UnityAction<AssetBundle> onGetAssetBundle)
{using (UnityWebRequest webRequest = UnityWebRequestAssetBundle.GetAssetBundle(path)){yield return webRequest.SendWebRequest();if (sult == UnityWebRequest.Result.Success){AssetBundle ab = (webRequest.downloadHandler as DownloadHandlerAssetBundle).assetBundle;onGetAssetBundle?.Invoke(ab);}else{Debug.Log("error = " +  + "n Load Path = " + path);onGetAssetBundle?.Invoke(null);}}
}

获取文本：

IEnumerator GetText(string path, UnityAction<string> onGetJson)
{using (UnityWebRequest webRequest = UnityWebRequest.Get(path)){yield return webRequest.SendWebRequest();if (sult == UnityWebRequest.Result.Success){string json = ;onGetJson?.Invoke(json);}else{Debug.Log("error = " +  + "n Load Path = " + path);onGetJson?.Invoke(null);}}
}

获取图片：

IEnumerator GetTexture2D(string path, UnityAction<Texture2D> onGetTexture2D)
{using (UnityWebRequest webRequest = UnityWebRequestTexture.GetTexture(path)){yield return webRequest.SendWebRequest();if (sult == UnityWebRequest.Result.Success){Texture2D tex2d = DownloadHandlerTexture.GetContent(webRequest);onGetTexture2D?.Invoke(tex2d);}else{Debug.Log("error = " +  + "n Load Path = " + path);onGetTexture2D?.Invoke(null);}}
}

获取音频：

IEnumerator GetAudio(string path, AudioType type, UnityAction<AudioClip> onGetAudio)
{using (UnityWebRequest webRequest = UnityWebRequestMultimedia.GetAudioClip(path, type)){yield return webRequest.SendWebRequest();if (sult == UnityWebRequest.Result.Success){AudioClip clip = DownloadHandlerAudioClip.GetContent(webRequest);onGetAudio?.Invoke(clip);}else{Debug.Log("error = " +  + "n Load Path = " + path);onGetAudio?.Invoke(null);}}
}

获取buffer

IEnumerator GetBuffer(string url, UnityAction<byte[]> act){using (UnityWebRequest webRequest = UnityWebRequest.Get(url)){yield return webRequest.SendWebRequest();if (sult == UnityWebRequest.Result.Success){byte[] buffer = webRequest.downloadHandler.data;act?.Invoke(buffer);}else{Debug.Log("error = " +  + "n Load Path = " + url);act?.Invoke(null);}}}

加载视频：

        这个事情早期版本要用到MovieTexure之类的，Unity目前版本加载视频实际上和UnityWebRequest没有毛线关系，请使用VideoPlayer，哈哈。

附一：

        Result枚举的介绍：

附二：

AssetBundle创建参考脚本（这个脚本注意放到Editor文件夹下）：

using System.IO;
using UnityEditor;
using UnityEngine;public class BuildAssetBundle : MonoBehaviour
{static void Package(BuildTarget buildTarget){string packagePath = EditorUtility.OpenFolderPanel("Set " + buildTarget + " Save Path", Application.dataPath, "");if (packagePath.Length <= 0 || !Directory.Exists(packagePath)){Debug.Log("Directory Error!");return;}BuildPipeline.BuildAssetBundles(packagePath, BuildAssetBundleOptions.None, buildTarget);AssetDatabase.Refresh();}[MenuItem("BuildAssetBundle / WebGL")]static void PackageWebGL(){Package(BuildTarget.WebGL);}[MenuItem("BuildAssetBundle / Window")]static void PackageWindow(){Package(BuildTarget.StandaloneWindows);}[MenuItem("BuildAssetBundle / Android")]static void PackageAndroid(){Package(BuildTarget.Android);}
}
