Saving jpg file with cloud-code Parse-Server

Question

I'm trying to save jpg files with cloud code on parse server ...

On Android I can do it using this way

Bitmap bitmap = ((BitmapDrawable) myImageView.getDrawable()).getBitmap();

ByteArrayOutputStream stream = new ByteArrayOutputStream();
                    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
                    byte [] byteArrayPhotoUpdate = stream.toByteArray();
                    final ParseFile pictureFileParse = new ParseFile( newUserInfo.getObjectId() + ".JPEG",byteArrayPhotoUpdate);

     newUserInfo.put("profile_picture",pictureFileParse);
     newUserInfo.saveInBackground();

But I have no idea how to do this in the cloud code. I call my cloud code functions like this

HashMap<String, String> params = new HashMap();

ParseCloud.callFunctionInBackground("myCloudFuncion", params, new FunctionCallback<String>() {
         @Override
          public void done(String aFloat, ParseException e) {

                }
            }); 

but I have no idea how to pass a bitmap in hashmap params. I already searched the internet, but nothing that I found in helped, the links that refer to something useful, is already old and outdated, from the epoch of the old parse ...

In parse docs I found this

    var base64 = "V29ya2luZyBhdCBQYXJzZSBpcyBncmVhdCE=";
    var file = new Parse.File("myfile.txt", { base64: base64 });

Which made me confused because I do not know if the 2 "base64" parameters refer to variable or base64 type

Should I convert my bitmap to base64 and send it as parameter to the cloud code?

If you have been through this and know how, I will be very happy to know your solution. Thank you!

Answer 1

you need convert your image bitmap for base64 like that:

            Bitmap bitmap = ((BitmapDrawable) img.getDrawable()).getBitmap();

            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
            byte [] byteArrayPhotoUpdate = stream.toByteArray();
            String encodedfile = new String(Base64.encodeBase64(byteArrayPhotoUpdate), "UTF-8");

And then, send your string base64 in params, like that:

 HashMap<String, String> params = new HashMap();
 params.put("fileInfo",encodedfile);
 ParseCloud.callFunctionInBackground("saveParseUserInfo", params, new FunctionCallback<String>() {
                    @Override
                    public void done(String aFloat, ParseException e) {

                     Log.i("ewaeaweaweaweawe", "done: " + aFloat);
                    }
                });

Now in your cloud code, use that:

Parse.Cloud.define("saveParseUserInfo", function(request, response) {
                var userId = request.user.id;
                var base64 = request.params.fileInfo;
                var userClass = Parse.Object.extend("User");
                //create a user object to set ACL
                var userObject = userClass.createWithoutData(userId);

                //create new ParseObject
                var userPublicClass = Parse.Object.extend("userPublic");
                var userPublic = new userPublicClass();
                var aclAction = new Parse.ACL(userObject);
                aclAction.setPublicReadAccess(true);
                userPublic.setACL(aclAction);
                userPublic.set("name", "name random");
                userPublic.set("username", "username_random");
                //Now create a Parse File object
                var file = new Parse.File("photo.jpeg", { base64: base64 });
                //set file object in a colum profile_picture
                userPublic.set("profile_picture",file);
                //save
                userPublic.save(null, { useMasterKey: true,  
                success: function(actionSuccess) {  

                    response.success("saved!!");
                },
                error: function(action, error) {
                    // Execute any logic that should take place if the save fails.
                    // error is a Parse.Error with an error code and message.
                response.error(error.message);
            }
            });






            });     

I hope it's help you.
