UnityWebRequest 可以实现网络数据请求功能支持GET post请求方法

1:GET请求服务器数据

    public static IEnumerator GetText(string url) {

        UnityWebRequest request =  UnityWebRequest.Get(url);
        yield return request.SendWebRequest();
        if (request.isNetworkError || request.isHttpError)
        {
            Debug.Log(request.error);
        }
        else
        {
            // 将结果显示为文本
            Debug.Log(request.downloadHandler.text);
            Result res =  JsonUtility.FromJson<Result>(request.downloadHandler.text);


        }
    }

2：下载纹理贴图

    //下载纹理http://www.my-server.com/image.png
    public static IEnumerable GetTexture(string url) {
        UnityWebRequest request = new UnityWebRequest(url);
        yield return request.SendWebRequest();

        if (request.isNetworkError || request.isHttpError)
        {
            Debug.Log(request.error);
        }
        else {
            Texture myTexture = ((DownloadHandlerTexture)request.downloadHandler).texture;
            // Texture myTexture = DownloadHandlerTexture.GetContent(request);
        }


    }

3：下载AB包

   //下载 AssetBundle http://www.my-server.com/myData.unity3d

    public static IEnumerable GetAssetBundle(string url) {

        UnityWebRequest request = new UnityWebRequest(url);
        yield return request.SendWebRequest();
        if (request.isNetworkError || request.isHttpError)
        {
            Debug.Log(request.error);
        }
        else {
            AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(request);
        }
    }

4：POST方法

    public static IEnumerable PostData(string url) {
        WWWForm data = new WWWForm();
     
        data.AddField("name", "jake");
        UnityWebRequest request = UnityWebRequest.Post(url,data);
        request.SetRequestHeader("token","werwerwer");
          yield return request.SendWebRequest();
       
        if (request.isNetworkError || request.isHttpError)
        {
            Debug.Log(request.error);
        }
        else { 
        
        }
    }
