未定义索引：HOSTINGER共享托管中的文件错误

Question

我有以下代码用于文件上传。这正在我的本地主机中使用IP地址。但是在Hostinger的共享托管中不起作用。它显示以下错误。请帮忙。

  

未定义索引：文件{“ exception”：“ [对象]（ErrorException（code：0）：未定义索引：文件位于/home/u766753775/domains/nammoor.online/public_html/laravel/routes/web.php： 527）

IONIC 4：

    async CameraImageUploadwithoutCrop() {
      await this.imagePicker.getPictures({ maximumImagesCount: 1, outputType: 0 }).then((results) => {
        for (const image of results) {
            console.log('Image URI: ' + image);
            const fileTransfer: FileTransferObject = this.transfer.create();
            const uploadOpts: FileUploadOptions = {
                fileKey: 'file',
                fileName: image.substr(image.lastIndexOf('/') + 1)
            };

            fileTransfer.upload(image, 'https://nammoor.online/post/uploadImage', uploadOpts)
            // fileTransfer.upload(image, 'http://191.168.01.10:8000/post/uploadImage', uploadOpts)
              .then((data) => {
                console.log(data);
                this.respData = JSON.parse(data.response);
                console.log(this.respData);
                this.imageUrl = this.respData.fileUrl;
              }, (err) => {
                console.log(err);
              });

        }
      }, (err) => { console.log(err); });
    }

PHP：

          Route::post('/post/uploadImage', function (Request $request) {

      // Route::post('image-upload', )->name('image.upload.post');
      $connection = OpenCon();

      // p($request);

    $date = date('dmYHis');
    $target_path = "uploads/images/".$date.".jpg";

        try {
          //if (move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) {
          if (move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) {

            //$fileUrl = "http://191.168.01.10:8000/".$target_path."";
            $fileUrl = "https://nammoor.online/".$target_path."";

            $eRes = json_encode('{ "fileUrl": "'.$fileUrl.'"}', true);
            p($fileUrl);
            $msg = json_decode($eRes ,true);
            p($msg);
            return $msg;
          } else {
          echo $target_path;
          } 
            }
          }, (err) => { console.log(err); });
        }
