使用Java API將觸發器添加到AWS Lambda函數

Question

如何使用Java API爲現有AWS Lambda函數添加新觸發器？

我想添加CloudWatch Events - Schedule觸發器。

看起來我應該使用AmazonCloudWatchEventsClient。 如何設置客戶端的憑據？

任何示例將不勝感激。

謝謝。

It is possible to add event sources via aws sdk. I faced the same issue and please see code below as the solution using java. 

AddPermissionRequest addPermissionRequest = new AddPermissionRequest(); 
       addPermissionRequest.setStatementId("12345ff"); //any unique string would go 
       addPermissionRequest.withSourceArn(ruleArn); //CloudWatch rule's arn 
       addPermissionRequest.setAction("lambda:InvokeFunction"); 
       addPermissionRequest.setPrincipal("events.amazonaws.com"); 
       addPermissionRequest.setFunctionName("name of your lambda function"); 

       AWSLambdaAsyncClient lambdaClient = new AWSLambdaAsyncClient(); 
       lambdaClient.withRegion(Regions.US_EAST_1); //region of your lambda's location 

lambdaClient.addPermission(addPermissionRequest);
