support of base64 string in S3Adapter

[mchun]

In the current file adapter of api.parse.com, I can see that both file and base64 string are supported.

e.g. data = {"_ContentType":"image/jpeg","base64":"/9j/4AAQSkZJRgABAQAAAQ..........."}
and also
data = $("#ulPhoto1")[0].files[0];

I do rely on this a lot when performing client-side resize image function.
Can we do the same in the S3Adapter?

P.S. This is the code I used to upload image.

$.ajax({
      type: "POST",
      beforeSend: function(request) {
        request.setRequestHeader("X-Parse-Application-Id", 'myAppId');
        request.setRequestHeader("X-Parse-REST-API-Key", 'myRestAPIKey');
        request.setRequestHeader("Content-Type", "image/jpeg");
      },
      url: "http://localhost:1337/parse/files/photo.jpg",
      data: data,
      processData: false,
      contentType: false,
      success: function(photo) {
           ......
      },
      error: function(jqXHR, textStatus, errorThrown)  {
           ......
      }
    });

What's the error that you get? If its request entity too large then its the same as #536

[mchun]

I did not face any error, but the image uploaded on S3 is simply unreadable.

@mchun does it work with Parse.File().save() ?

[mchun]

It works with Parse.File("photo.jpg", { base64 : data }). But it would be great if it can be done via REST api too.

[flovilmart]

ok, that's good to know, Did you try with the latest 'master"?

[mchun]

Just tried with 2.1.3 and the problem still exists.

[flovilmart]

I'll have a look

@mchun we fixed a few things with the content type in recent releases, and I just checked, the base64 is properly restored as a buffer in the early middlewares.
Please retry on 2.1.6 and I'll reopen if needed.

I have just tried 2.1.6, but sadly it is still not working...
When using the Parse hosted server, the following works without problem:

    $.ajax({
      type: "POST",
      beforeSend: function(request) {
        request.setRequestHeader("X-Parse-Application-Id", 'myAppId');
        request.setRequestHeader("X-Parse-REST-API-Key", 'myRestAPIKey');
        request.setRequestHeader("Content-Type", "image/jpeg");
      },
      url: serverUrl,
      data: data,
      processData: false,
      contentType: false,
      success: function(photo) {...}
  });

where data is the following..(unlike what I described in the original post, my bad)

var data = JSON.stringify({
            '_ContentType':"image/jpeg",
            'base64': "/9j/4AAQSkZJRgABAQAAAQ..........."
          });

I have tried many thing, like removing "_" of ContentType inside data, changing the contentType of $.ajax to "image/jpeg", not stringifying the object....etc, but nothing works. Did I do anything wrongly?

The file can be save successfully but it is not viewable. i.e.,

I try to save base64 file using REST, it seems not working
