[Solved] error copying file from streaming assets on IOS

Question

Hello people, Im getting a error when I try to copy a file from StreamingAssets Application.dataPath to Application.persistentDataPath

On android works fine, but on IOS im getting this error:

 *App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Use HTTPS instead or add Exception Domains to your app's Info.plist.
 *Cannot start load of Task <XXXXXXX>.<2> since it does not conform to ATS policy
 *Task <XXXXXXX>.<2> finished with error [-1022] Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=The resource could not be loaded because the App Transport Security policy requires the use of a secure connection., NSErrorFailingURLStringKey=http://localhost/private/var/containers/Bundle/Application/XXXXXXX/AppnName/Data/Raw/xlsx/puestaapunto.xlsx, NSErrorFailingURLKey=http://localhost/private/var/containers/Bundle/Application/XXXXXXX/AppnName/Data/Raw/xlsx/puestaapunto.xlsx, _NSURLErrorRelatedURLSessionTaskErrorKey=(

 ), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <XXXXXXX>.<2>, NSUnderlyingError=0x280b88a80 {Error Domain=kCFErrorDomainCFNetwork Code=-1022 "(null)"}}

SOLVED

this code works for android:

 #if UNITY_ANDROID
                 string oriPath = Path.Combine("jar:file://" + Application.dataPath + "!/assets/xlsx/", ExcelFileName + ".xlsx"); //returns a DirectoryInfo object
                 UnityWebRequest reader = UnityWebRequest.Get(oriPath);
                 reader.SendWebRequest();
                 while (!reader.isDone) { }
                 realPath = Application.persistentDataPath + "/xlsx/" + ExcelFileName + ".xlsx"; //save the file with this name
                 File.WriteAllBytes(realPath, reader.downloadHandler.data);
                 Debug.Log("Excel File generated in app data from StreamingAssets");
                 #endif

and this code works for iOS:

 #if UNITY_IOS
                 realPath = Application.persistentDataPath + "/xlsx/";
                 string oriPath = Path.Combine(Application.streamingAssetsPath + "/xlsx", ExcelFileName + ".xlsx"); //returns a DirectoryInfo object
                 byte[] xlsxFile = File.ReadAllBytes(oriPath);
                 File.WriteAllBytes(realPath + ExcelFileName + ".xlsx", xlsxFile); //save the file with this name
                 //File.WriteAllBytes(realPath + "puestaapunto.xlsx", xlsxFile); //alternative of above line, working
                 Debug.Log("Excel File generated in app data from StreamingAssets");
                 #endif

Hi, thanks for answering, I tried this from that link:

  public class BypassCertificate : CertificateHandler
     {
         protected override bool ValidateCertificate(byte[] certificateData)
         {
             //Simply return true no matter what
             return true;
         }
     }

If I dont understand bad, all what I need to do is put that script code on plugin folder, right?, no need to attatch to some gameobject?, Im sure im missing something.

also I tried the method of edit info.plist on xcode:

 <key>NSAppTransportSecurity</key>
   <dict>
     <key>NSAllowsArbitraryLoads</key>
     <true/>
   </dict>

but do nothing, the error keeps as same.

Also I triying another method to avoid certificates:

 public void Test6()
     {        
         Directory.CreateDirectory(Application.persistentDataPath + "/xlsx"); //create a directory/folder
         string oriPath = Path.Combine(Application.dataPath + "/Raw/xlsx/", "puestaapunto"); //returns a DirectoryInfo object  //check if this line works on ios        
         realPath = Application.persistentDataPath + "/xlsx/";
         //realPath = Application.persistentDataPath + "/xlsx/" + "puestaapunto2.xlsx";
         var rewrite = Resources.Load<TextAsset>(oriPath);
         byte[] data = rewrite.bytes;
         File.WriteAllBytes(realPath, data);
     }

but I get: nullReferenceException: Object reference not set to an instance of an object

to the plugin folder no, to your scripts folder. You would also need to add this to your coroutine

 www.certificateHandler = new BypassCertificate();

oriPath is not a file (or it has no extension) so I am not sure what you are trying to load in resources.load

Hi again, finally I make it work for iOS with a correct syntaxis:

  public void Test10()
         {
             realPath = Application.persistentDataPath + "/xlsx/";
             string oriPath = Path.Combine(Application.streamingAssetsPath + "/xlsx", "puestaapunto" + ".xlsx");
             Debug.Log("file read from streamingassets");
             byte[] xlsxFile = File.ReadAllBytes(oriPath);
             File.WriteAllBytes(realPath + "puestaapuntoWrited2.xlsx", xlsxFile);
             Debug.Log("file copied to persistentDataPath");
         }
