Question

我正在构建Google App Script产品，该产品可将pdf文件上传到Google Cloud Storage，并且效果很好（感谢tutorial）。但是我无法获取上传的文件URL。

这是我的uploadFileToGCS()函数：

function uploadFileToGCS() {

  var service = getService();
  if (!service.hasAccess()) {
    Logger.log("Please authorize %s", service.getAuthorizationUrl());
    return;
  }

  var blob = DriveApp.getFileById(params.DRIVE_FILE).getBlob();
  var bytes = blob.getBytes();

  var url = 'https://www.googleapis.com/upload/storage/v1/b/BUCKET/o?uploadType=media&name=FILE'
    .replace("BUCKET", params.BUCKET_NAME)
    .replace("FILE", encodeURIComponent(params.FILE_PATH));

  var response = UrlFetchApp.fetch(url, {
    method: "POST",
    contentLength: bytes.length,
    contentType: blob.getContentType(),
    payload: bytes,
    headers: {
      Authorization: 'Bearer ' + service.getAccessToken()
    }
  });

  var result = JSON.parse(response.getContentText());
  Logger.log(JSON.stringify(result, null, 2));
}

响应日志：Logger.log(JSON.stringify(result, null, 2));

}

当我单击到mediaLink时，浏览器会自动下载我的pdf文件，这不是我想要的。

那么如何通过GAS从Google Cloud Storage获取上传的URL文件？欢迎任何建议！
