如何使用aws SDK为AWS Lambda函数创建CloudWatch日志触发器？

Question

我根据https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CloudWatchLogs.html#putSubscriptionFilter-property

的NodeJS

const AWS = require('aws-sdk');
AWS.config = new AWS.Config
    ({
        accessKeyId: "AKIA******",
        secretAccessKey: "6RJf******vy",
    });
const cloudwatchlogs = new AWS.CloudWatchLogs({ region: 'a******1' });

var params = {
    destinationArn: 'arn:aws:lambda:******:function:******', 
    filterName: 'LambdaStream_******', 
    filterPattern: '?Error ?Waring ?error ?"node(1)" ?info ?INFO', 
    logGroupName: '/aws/lambda/******', 
    distribution: 'ByLogStream',
};
cloudwatchlogs.putSubscriptionFilter(params, function (err, data) {
    if (err) console.log( err, err.stack);
    else console.log(data);
});

我会收到以下错误：

 { InvalidParameterException: Could not execute the lambda function. Make sure you have given CloudWatch Logs permission to ex ecute your function.
    at Request.extractError 

......

(/mnt/******/node_modules/aws-sdk/lib/sequential_executor.js:116:18) message: 'Could not execute the lambda function.

我给了这些执行角色：

  AWSLambdaFullAccess
  CloudWatchFullAccess
  CloudWatchLogsFullAccess
  AmazonVPCFullAccess
  AWSLambdaVPCAccessExecutionRole
  AWSLambdaRole

        }
    ]
}

Answer 1

这是您在角色策略中获得CloudWatch Full Access所需的全部内容。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "logs:*",
            "Resource": "*"
        }
    ]
}

Answer 2

var params = {
Action: 'lambda:InvokeFunction', /* required */
FunctionName: 'arn:aws:lambda:******:******:function:******', /* required */
Principal: 'logs.*region*.amazonaws.com', /* required */
StatementId: '******', /* required */
// SourceAccount: '******',
// SourceArn: 'arn:aws:logs:::******:******'
};

lambda.addPermission(params, function (err, data) {
    if (err) console.log(err, err.stack); // an error occurred
    else console.log(data);           // successful response
});
