AWS Kinesis Firehose 未响应 Lambda

AWS Kinesis Firehose not responding to Lambda

这是 Lambda 代码:

const AWS = require('aws-sdk');
var firehose = new AWS.Firehose({ region: 'ap-southeast-2' });

exports.handler = async (event, context) => {

var params = {
    DeliveryStreamName: 'TestStream', 
    Record: {
        Data: 'test data'
    }
};
console.log('params', params);

firehose.putRecord(params, function (err, data) {
    if (err) console.log(err, err.stack); // an error occurred
    else console.log('Firehose Successful',  data);           // successful response
});

}

政策是:

{
"Version": "2012-10-17",
"Statement": [
    {
        "Effect": "Allow",
        "Action": [
            "firehose:DeleteDeliveryStream",
            "firehose:PutRecord",
            "firehose:PutRecordBatch",
            "firehose:UpdateDestination"
        ],
        "Resource": [
            "arn:aws:firehose:ap-southeast-2:xxxxxxxxxxxxx:deliverystream/TestStream"
        ]
    }
]

}

我已经完全删除了所有其他内容。我在 cloudwatch 中看到的响应是:

所以,执行到达消防水管线,直接越过它们,什么都不做...

由于您使用的是 async handler,我认为问题是您的函数在 firehose 代码有机会 运行.

之前完成

纠正此问题的一种方法是使用 Promise,如 AWS docs 所示。例如:

const AWS = require('aws-sdk');
var firehose = new AWS.Firehose({ region: 'ap-southeast-2' });

exports.handler = async (event, context, callback) => {

    const promise = new Promise(function(resolve, reject) {

     var params = {
       DeliveryStreamName: 'TestStream', 
       Record: {
          Data: 'test data'
       }
     };
     console.log('params', params);

    firehose.putRecord(params, function (err, data) {
       if (err) console.log(err, err.stack); // an error occurred
       else console.log('Firehose Successful',  data);           //         successful response
     });
  })

  return promise;   
};

以上更改仅供参考,因此可能仍需要进行一些调整。
