How to deal with binary data (blob)? #52

Closed patrick-heuer closed 8 years ago

patrick-heuer commented 9 years ago

I have a TClientDataset having a field containing binary data (TBlobField). I´m using "TResource.GetAsDataSet" and "TResource.GetAsDataSet(ADataSet: TDataSet)", but it seems for me not to be possiblt to marshal binary data from JSON...

Any idea´s how to deal with binary data? Example?

Thx!

Hi @PKrause79

AFAIK, JSON does not support binary.

I don't remember doing anything like this, so, I'm not sure I can help you.

The first thing that comes to my mind was use a BASE64 serialization and then put it on the JSON. I think the SuperObject has some "Stream" methods, which may help you too.
