我所看到的就是这种类型的数据:
phi=(1+math.sqrt(5))/2
当我进行此调用以从队列中读取时:
{
MessageId: 'c604c772-8468-4cd2-8f3e-9b430ed52d92',
ReceiptHandle: 'AQEBHyPYuNqFztvy9QNOHeLQg==',
MD5OfBody: '096c6509c8628bde267adde2b105f4e4',
Body: 'foobar'
}
但是我在将消息放入队列时添加了MessageAttributes:
sqs.sendMessageBatch({QueueUrl,Entries:v},cb);
条目是一个数组:
const conf = {
QueueUrl: 'https://sqs.us-west-2.amazonaws.com/920371/logging-q',
WaitTimeSeconds: 19, // max is 20 (off by one errors avoided!)
MaxNumberOfMessages: 9 // max is 10 (off by one errors avoided!)
};
sqs.receiveMessage(conf, cb);
有人知道为什么当我从队列中读取消息时,MessageAttributes却没有出现吗?
答案 0 :(得分:3)
在您的receiveMessage
conf中,您需要包括MessageAttributeNames
并为其提供属性名称列表或All
。看来您使用的是JavaScript,所以您想看看receiveMessage
