EventBridge examples using SDK for C++

The following code examples show you how to perform actions and implement common scenarios by using the AWS SDK for C++ with EventBridge.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

Actions

PutEvents

The following code example shows how to use PutEvents.

SDK for C++

Note

There's more on GitHub. Find the complete example and learn how to set up and run in the AWS Code Examples Repository.

Include the required files.

#include <aws/core/Aws.h>
#include <aws/events/EventBridgeClient.h>
#include <aws/events/model/PutEventsRequest.h>
#include <aws/events/model/PutEventsResult.h>
#include <aws/core/utils/Outcome.h>
#include <iostream>

Send the event.

        Aws::CloudWatchEvents::EventBridgeClient cwe;

        Aws::CloudWatchEvents::Model::PutEventsRequestEntry event_entry;
        event_entry.SetDetail(MakeDetails(event_key, event_value));
        event_entry.SetDetailType("sampleSubmitted");
        event_entry.AddResources(resource_arn);
        event_entry.SetSource("aws-sdk-cpp-cloudwatch-example");

        Aws::CloudWatchEvents::Model::PutEventsRequest request;
        request.AddEntries(event_entry);

        auto outcome = cwe.PutEvents(request);
        if (!outcome.IsSuccess())
        {
            std::cout << "Failed to post CloudWatch event: " <<
                outcome.GetError().GetMessage() << std::endl;
        }
        else
        {
            std::cout << "Successfully posted CloudWatch event" << std::endl;
        }

PutRule

The following code example shows how to use PutRule.

SDK for C++

Note

There's more on GitHub. Find the complete example and learn how to set up and run in the AWS Code Examples Repository.

Include the required files.

#include <aws/core/Aws.h>
#include <aws/events/EventBridgeClient.h>
#include <aws/events/model/PutRuleRequest.h>
#include <aws/events/model/PutRuleResult.h>
#include <aws/core/utils/Outcome.h>
#include <iostream>

Create the rule.

        Aws::CloudWatchEvents::EventBridgeClient cwe;
        Aws::CloudWatchEvents::Model::PutRuleRequest request;
        request.SetName(rule_name);
        request.SetRoleArn(role_arn);
        request.SetScheduleExpression("rate(5 minutes)");
        request.SetState(Aws::CloudWatchEvents::Model::RuleState::ENABLED);

        auto outcome = cwe.PutRule(request);
        if (!outcome.IsSuccess())
        {
            std::cout << "Failed to create CloudWatch events rule " <<
                rule_name << ": " << outcome.GetError().GetMessage() <<
                std::endl;
        }
        else
        {
            std::cout << "Successfully created CloudWatch events rule " <<
                rule_name << " with resulting Arn " <<
                outcome.GetResult().GetRuleArn() << std::endl;
        }

PutTargets

The following code example shows how to use PutTargets.

SDK for C++

Note

There's more on GitHub. Find the complete example and learn how to set up and run in the AWS Code Examples Repository.

Include the required files.

#include <aws/core/Aws.h>
#include <aws/events/EventBridgeClient.h>
#include <aws/events/model/PutTargetsRequest.h>
#include <aws/events/model/PutTargetsResult.h>
#include <aws/core/utils/Outcome.h>
#include <iostream>

Add the target.

        Aws::CloudWatchEvents::EventBridgeClient cwe;

        Aws::CloudWatchEvents::Model::Target target;
        target.SetArn(lambda_arn);
        target.SetId(target_id);

        Aws::CloudWatchEvents::Model::PutTargetsRequest request;
        request.SetRule(rule_name);
        request.AddTargets(target);

        auto putTargetsOutcome = cwe.PutTargets(request);
        if (!putTargetsOutcome.IsSuccess())
        {
            std::cout << "Failed to create CloudWatch events target for rule "
                << rule_name << ": " <<
                putTargetsOutcome.GetError().GetMessage() << std::endl;
        }
        else
        {
            std::cout <<
                "Successfully created CloudWatch events target for rule "
                << rule_name << std::endl;
        }
