Ionic capacitor file download with PHP

I just started on ionic. all are going good.

But I got stuck on file/attachment download in ionic.

For this I used below two method but no success, Any help will be appreciated.

First Method:-

download(fileURL: any, filename: any) {

this.platform.ready().then(() => {

      const fileTransfer: FileTransferObject = this.transfer.create();
      let url = encodeURI(fileURL); // *PHP FILE PATH download.php*
      let path = null;
      //   //Check plateform 
      if (this.platform.is('ios')) {
        path = this.file.documentsDirectory;
      }
      else {
        path = this.file.externalDataDirectory;
      }
      //   //Process download
      fileTransfer.download(url, path + filename, false).then((entry) => {
        console.log('download complete: ' + entry.toURL());
      }, (error) => {
        console.log('download EROR: ' + JSON.stringify(error));
      });
      });
  }

**

Result:- Err, error code 3 status 401

Second method:-

download(fileURL: any, filename: any) {

this.platform.ready().then(() => {

      let url = encodeURI(fileURL);// *PHP FILE PATH download.php*
      let path = null;
      //   //Check plateform 
      if (this.platform.is('ios')) {
        path = this.file.documentsDirectory;
      }
      else {
        path = this.file.externalDataDirectory;
      }

      this.http.get(url, { responseType: "arraybuffer" }).subscribe(
        (imageBlob: any) => {
            console.log('Blob' + imageBlob);
            return this.file.writeFile(path, filename, imageBlob, { replace: true, append: false }
            ).then(file => { console.log(JSON.stringify(file)); })
              .catch(err => {
                alert(JSON.stringify("Error 1: " + err));
              });
          
        }, error => {
          alert(JSON.stringify("Error 2: " + error));
          console.log(error);
        }
      );
    });
   }

Result:- No err, but file do not save in device.
