如何使用Amazon S3 GetObject的-Aws SDK 2.2.6时指定本地目标路径 [英] How to specify local destination path when using Amazon S3 GetObject -Aws sdk 2.2.6

问题描述

下面code成功地使用从我的S3存储下载的数据AWS-SDK 2.2.6。

The following code successfully downloads data from my S3 storage using Aws-sdk 2.2.6.

    return $scope.download = function(fileName, indexf) {
      var bucket, params, test;
      $scope.videoFileDownload[indexf] = true;
      test = 0;
      AWS.config.update({
        accessKeyId: 'mykey',
        secretAccessKey: 'mysecret'
      });
      AWS.config.region = 'us-west-2';
      bucket = new AWS.S3({
        params: {
          Bucket: 'mybucket'
        }
      });
      params = {
        Key: fileName
      };
      return bucket.getObject(params, function(err, data) {
        if (err) {
          setAlert(true, 'alert alert-danger', 'Error!', err);
          return false;
        } else {
          $scope.videoFileDownload[indexf] = false;
          setAlert(true, 'alert alert-success', 'Success!', 'File Downloaded');
          setTimeout((function() {
            $scope.uploadProgress = 0;
            $scope.$digest();
          }), 4000);
        }
      }).on('httpDownloadProgress', function(progress) {
        var progresss3;
        progresss3 = Math.round(progress.loaded / progress.total * 100);
        $(".progress .progress-bar").css("width", progresss3 + "%");
        $(".progress .progress-bar").attr("aria-valuenow", progresss3);
        $scope.$digest();
      });
    };
  });

我怎么能修改此code将下载的数据保存到一个特定的本地文件路径的前端。

How can I modify this code to save the downloaded data to a specific local file path on the front end.

推荐答案

在FS是与服务器的文件系统进行交互的nodejs相关的对象，但这个片段似乎是前端code

The "fs" is a nodejs related object for interacting with the server file system, but this snippet appears to be front end code.

如果你想修改该文件存储在前端，你不能，这是由浏览器来控制。如果你可以节省服务器上的文件，可以使用FS对象。

If you're trying to alter where the file stores for the front end, you can't, that's controlled by the browser. If you're saving a file on the server, you can use the fs object.
