Hello -
I have requirement to convert json byte stream to pdf in messgae broker , Can someone let me know how to do the same in ESQL or Java Compute node in message broker.
Sample json message :{"headers":{},"body":{"pdfByteArray":"amF2YS5pby5GaWxlSW5wdXRTdHJlYW1ANzYyYTc2MmE="}}
I need to convert "amF2YS5pby5GaWxlSW5wdXRTdHJlYW1ANzYyYTc2MmE="
to pdf in ESQL or JCN.
Much appreciated!
thanks ! |

I would guess that the value of 'pdfByteArray' is a PDF document encoded as base64. I would use ESQL's base64Decode function to turn it into a BLOB. Then you can write the BLOB to a file.

As kimbert said, you can use the base64decode function. But before, be sure of pdfByteArray's content:
In your sample, this base64 encoded:
| Code: |
| amF2YS5pby5GaWxlSW5wdXRTdHJlYW1ANzYyYTc2MmE= |
decoded is:
| Code: |
| java.io.FileInputStream@762a762a |
