app.post('/uploadto/s3/drtivepdf', function (req, res, next) {

这是我的file.js代码： - '

                        mode: 'pdf'

                }
            });
        }

上传工作正常，但是当我尝试在S3上查看该文件时，我无法打开它。

任何原因？

谢谢

要使用JS下载所选文件，请使用此

function downloadFile(file, callback) {
  if (file.downloadUrl) {
    var accessToken = gapi.auth.getToken().access_token;
    var xhr = new XMLHttpRequest();
    xhr.open('GET', file.downloadUrl);
    xhr.setRequestHeader('Authorization', 'Bearer ' + accessToken);
    xhr.onload = function() {
      callback(xhr.responseText);
    };
    xhr.onerror = function() {
      callback(null);
    };
    xhr.send();
  } else {
    callback(null);
  }
}
