transferring data to Amazon Web Services using Angular framework

I'm currently facing an issue while trying to send a file to an AWS server using an Angular dropzone. I have my AWS credentials ready, but I am unsure of how to properly make the request.

Every time I attempt to drop the file into the dropzone, I keep receiving an error message saying 'POST 400 (Bad Request)'

angular.extend($scope, {
      dropzoneConfig: {
        'options': {
          'url':'https://url.com',
        },

        'eventHandlers': {
          'sending': function(file, formData, xhr) {
              console.log('sending');
          },
          'success': function(file, response) {
            console.log('sent');
          },
          'error': function() {
            console.log('error');
            $scope.hideDropzone = true;
          }
        }
      }
    });

Answer №1

This task is extremely challenging. To summarize:

  1. Use the fileReader object to read a file.
  2. Obtain a presigned URL from an Amazon server (via PHP or another server-side script).
  3. Send a PUT request to the presigned URL with the encoded file buffer content.
  4. If the PUT request is successful, display a message to the user.
