unity使用 WXAssetBundle.GetAssetBundle(url)下载资源成功，但是assetbundle为空，用UnityWebRequestAssetBundle.GetAssetBundle又可以正常加载

[wumiao1990]

描述Bug

UnityEngine.Networking.UnityWebRequest bundleReq = WeChatWASM.WXAssetBundle.GetAssetBundle(urlPath); // UnityWebRequestAssetBundle => WXAssetBundle
await bundleReq.SendWebRequest();
if (bundleReq.result == UnityEngine.Networking.UnityWebRequest.Result.Success)
{
UnityEngine.AssetBundle bundle = null;
try
{
var downloadHandler = bundleReq.downloadHandler;
bundle = (downloadHandler as DownloadHandlerWXAssetBundle)?.assetBundle; // DownloadHandlerAssetBundle => DownloadHandlerWXAssetBundle
Debug.LogError($"WXAssetBundle.GetAssetBundle Path：{urlPath} bundle:{bundle}");
}
catch (Exception e)
{
Logging.Error($"{GetType()} bundle is Null path：{urlPath} errorMsg:{e}");
}
if (bundle != null)
{
m_AssetBundle = bundle;
}
IsDone = true;
}
else
{
Logging.Error($"{GetType()} ERROR bundleReq.error path：{urlPath}");
}
bundleReq.Dispose();

运行环境

Unity2022.3.22

为null一般是网络错误，检查小游戏是否有相关日志。建议补上网络的判断 bundleReq.isHttpError || bundleReq.isNetworkError
