Nodejs SDK:从aws-cli添加s3 bucket事件通知getInvalidArgument:无法验证以下目

Question

我使用nodejs-ssimple-sdk执行了以下方法将事件通知添加到s3 bucket来自ec2实例。

var params={
Bucket: name,
NotificationConfiguration: {
QueueConfigurations: [],
TopicConfigurations: [],        
LambdaFunctionConfigurations: [{
"Id": "enableS3EventForTransformCurLambda",
"LambdaFunctionArn": arn,
"Events": [ "s3:ObjectCreated:*" ],
"Filter": { "Key": { "FilterRules": [ { "Name": "Suffix", "Value": ".json" } ] } }
}
]
}
}

const notifevent = await s3.putBucketNotificationConfiguration(paramsNotif).promise();

现在我得到错误

InvalidArgument: Unable to validate the following destination configurations

它构造了正确的参数

Answer 1

我能够通过向s3事件触发的Lambda添加权限来解决这个问题。

旁路

async function addPermissionToLambda(){

var lambda = new AWS.Lambda();
var paramsForNotification = {
Action: "lambda:InvokeFunction", 
FunctionName: "lambda-fn", 
Principal: "s3.amazonaws.com", 
SourceAccount: acctNum, 
SourceArn: "arn:aws:s3:::*-test-bucket", 
StatementId: "s3LambdaInvokeViaS3Event"
};

var paramsForGetPolicy = {
FunctionName: "lambda-fn"
};



try{
const permission = await lambda.addPermission(paramsForNotification).promise()
console.log("Permission Added to the lambda for invoke it")


}catch(err){
console.log("Error occured while addding permissioon to lambda")
console.log(err, err.stack)
}

}

现在，您可以轻松地将事件通知添加到bucket中。
