QueueOutput Interface
Implements
public interface QueueOutput
implements java.lang.annotation.Annotation
Place this on a parameter whose value would be written to a storage queue. The parameter type should be OutputBinding, where T could be one of:
- Any native Java types such as int, String, byte[]
- Any POJO type
The following example shows a Java function that creates a queue message for each HTTP request received.
@FunctionName("httpToQueue")
@QueueOutput(name = "item", queueName = "myqueue-items", connection = "AzureWebJobsStorage")
public String pushToQueue(
@HttpTrigger(name = "request", methods = {HttpMethod.POST}, authLevel = AuthorizationLevel.ANONYMOUS)
final String message,
@HttpOutput(name = "response") final OutputBinding<String> result
) {
result.setValue(message + " has been added.");
return message;
}
