Protobufs with web stomp

[pantonis]

We have a problem with working with Google Protobufs.

Publisher is a .NET service and serializes the body using google protobufs.

Subscriber is a javascript which connect to rabbitmq using the web-stomp plugin (websockets).

Javascript subscriber cannot decode the message and gives following error:

"EXCEPTION: Error: Illegal character code: 10"

Cannot find anything about this error on google.

Thanks in advance.

Hi,

It sounds like your javascript application may be trying to decode the protobuf body as json. I'd suggest you take first take RabbitMQ out of the equation and serialize some data using the .NET code to file then try to deserialize that data using javascript to make sure this works.

Cheers

I tried your suggestion.

With Http request it works perfectly fine.

When I use plain websockets and add the socket type to arraybuffer I still get the error.

Illegal wire type in unknown group 12: 7 I google it and I got the following:

From what I read here it stated that data can be corrupted if they are read as a string

When I said plain websockets I meant to connect to the rabbitmq exchange.
