Answer 1

var data={
"Records": [{
    "messageId": "20ea364e-3bc107b5c78c",
    "receiptHandle": "AQEB6DhNloFS4R66c=",
    "body": "1",
    "attributes": {
        "ApproximateReceiveCount": "1",
        "SentTimestamp": "15393506",
        "SenderId": "AROAJMTI6NE:errorLog",
        "ApproximateFirstReceiveTimestamp": "15393511"
    },
    "messageAttributes": {},
    "md5OfBody": "c4ca75849b",
    "eventSource": "aws:sqs",
    "eventSourceARN": "arn:aws:sqs:ap-suth-1:83362:escalateErrorStandardQueue",
    "awsRegion": "ap-south-1"
}]
};
console.log(data.Records[0].body);

您只需通过data.Records[0].body即可访问数据。
