示例1: consumeChannel
private consumeChannel(channel: Channel): void {
channel.consume(
REPLY_QUEUE,
(msg: Message) => this.responseEmitter.emit(msg.properties.correlationId, msg.content),
{noAck: true}
);
}示例2:
.then((channel: Channel) => {
self._channel = channel;
// Assert Queue
channel.assertQueue(
self.queueName,

console.log(`Awaiting RPC Requests On: ${self.queueName}`);
}
// Consume Messages
self.consumeChannel.apply(self, [channel, actionFunction]);
return self._channel;
});示例3:
.then((channel: Channel) => {

channel.setMaxListeners(0);
// Action to take when message received
self.consumeChannel.apply(self, [channel]);
return channel;
