I am new to Azure logic apps. I have a service bus and pass a json object message to that service bus then I set up an action in logic apps to listen to my service bus. So everytime a new message come in to that service bus my logic apps will pick it up
and send it to http.
My question is how can I grab the property from the message in service bus and pass it to my http action. I tried this
“Id” : “@{json(triggerBody()[‘ContentData’]).id}”
but it's not working
Who and how is sending the message on the queue?
I read a json message property (DestinationPath) in this way:
@{json(base64ToString(triggerBody()?['ContentData'])).DestinationPath}
Here is how my Logic App looks like
and in my case the message is sent from an Azure webjob as a BrokeredMessage:
string jsonMessage = JsonConvert.SerializeObject(myObject);
Stream streamMessage = new MemoryStream(Encoding.UTF8.GetBytes(jsonMessage));
BrokeredMessage msg = new BrokeredMessage(streamMessage);
client.Send(msg);
Logic app now has expressions to decode Base 64 encoded value.
My requirement was to decode the encoded ServiceBus message to an Azure Function. I solved this using Logic App Expression, decodeBase64() which can accept a dynamic content of type string, in this case the 'Content'- Content of the message, and returns the decoded json string. decodeBase64(triggerBody()?['ContentData'])
Find attached the screen shots for reference.
In the place holder for input to the action, include an expression and choose decodeBase64()
