After downloading the AssetBundle, how do I save it locally？

When I downloaded the AssetBundle and saved it, I ran into a problem at "byte[] results = request1.downloadHandler.data;" An error is as follows： “unity Failed to read data for the AssetBundle”

Here is my code： public IEnumerator GetRequest(string url) { UnityWebRequest request1 = UnityEngine.Networking.UnityWebRequestAssetBundle.GetAssetBundle(url);

     yield return request1.SendWebRequest();

     if (request1.isDone)
     {
         if (request1.result != UnityWebRequest.Result.Success)
         {
             Debug.Log(request1.error);
         }
         else
         {
             AssetBundle ab = UnityEngine.Networking.DownloadHandlerAssetBundle.GetContent(request1);

             //加载AB包
             loadKeshengAB(ab);

             byte[] results = request1.downloadHandler.data;
             Debug.Log(results.Length);

             saveABToLocal(results);
         }
     }
 }

 void saveABToLocal(byte[] results) {
     //byte[] results = request1.downloadHandler.data;
     FileInfo fileInfo = new FileInfo(localPath + "/" + filename);
     FileStream fs = fileInfo.Create();
     //fs.Write(字节数组, 开始位置, 数据长度);
     fs.Write(results, 0, results.Length);
     fs.Flush(); //文件写入存储到硬盘
     fs.Close(); //关闭文件流对象
     fs.Dispose(); //销毁文件对象
 }
