Remarks
The method parameter type can be one of the following:
- QueueMessage
- String
- byte[]
- BinaryData
- A user-defined type (serialized as JSON)
By default messages received from the queue are expected to be Base64-encoded and are decoded before calling the function. This behavior can be changed by setting MessageEncoding. For example, to configure Azure Functions to perform no base64 encoding/decoding, specify the following in host.json.
"extensions": {
"queues": {
"messageEncoding": "none"
}
}
