Using getFormPostParams

[KrunchMuffin]

I know it says TODO, but can you TODO it now? lol. I am getting a signature mismatch and wondering if it's because I am not using this.

I am not sure what you are trying to do when you get the signature mismatch? This method is there to help with POSTing from a browser directly to S3, but I haven't thought in detail about the best way to make that available to people using the library (though I myself do use it in its current state extensively as is).

I am using Uppy. It does a direct upload after I get a presigned key. Supposed to any way.

Are you trying to do PUT or POST requests? This method is only for using POST. For example:

// in CFML

// Whatever form fields you intend to pass with the request go here
var formFields = [
    { name: 'acl', value: 'private' },
    { name: 'success_action_status', value: '201' },
    { name: 'Content-Type', value: 'application/pdf' },
    { name: 'Content-Disposition', value: 'attachment; filename="myfile.pdf"' },
    { name: 'name', value: 'myfile.pdf' }
];

formFields.append(
    aws.s3.getFormPostParams(
        'my_s3_bucket',
        'my_key', 
        formFields
    ),
    true
);

var formFieldsStruct = formFields.reduce( function( resultStruct, item ) {
    resultStruct[ item.name ] = item.value;
    return resultStruct;
}, { } );

// use these fields in a struct that could be serialized to JSON and returned to the client
var uploadParameters = { 
    method: 'POST', 
    url: 'https://my_s3_bucket.s3.amazonaws.com', 
    fields: formFieldsStruct, 
    headers: {} 
};

You could then use the uploadParameters in Uppy, it looks like: https://uppy.io/docs/aws-s3 - I haven't used Uppy myself, so this may require some tweaking to get it to work.

Thanks, I'll check it out.
