ListRuleNamesByTarget与 S Amazon DK 或命令行工具配合使用

使用目标列出所有规则名称。

    /// <summary>
    /// List names of all rules matching a target.
    /// </summary>
    /// <param name="targetArn">The ARN of the target.</param>
    /// <returns>The list of rule names.</returns>
    public async Task<List<string>> ListAllRuleNamesByTarget(string targetArn)
    {
        var results = new List<string>();
        var request = new ListRuleNamesByTargetRequest()
        {
            TargetArn = targetArn
        };
        ListRuleNamesByTargetResponse response;
        do
        {
            response = await _amazonEventBridge.ListRuleNamesByTargetAsync(request);
            results.AddRange(response.RuleNames);
            request.NextToken = response.NextToken;

        } while (response.NextToken is not null);

        return results;
    }

显示具有指定目标的所有规则

此示例显示了所有以名为 “MyFunctionName” 的 Lambda 函数作为目标的规则：

aws events list-rule-names-by-target --target-arn "arn:aws:lambda:us-east-1:123456789012:function:MyFunctionName"

列出使用此目标的所有规则名称。

    public static void listTargetRules(EventBridgeClient eventBrClient, String topicArn) {
        ListRuleNamesByTargetRequest ruleNamesByTargetRequest = ListRuleNamesByTargetRequest.builder()
                .targetArn(topicArn)
                .build();

        ListRuleNamesByTargetResponse response = eventBrClient.listRuleNamesByTarget(ruleNamesByTargetRequest);
        List<String> rules = response.ruleNames();
        for (String rule : rules) {
            System.out.println("The rule name is " + rule);
        }
    }

suspend fun listTargetRules(topicArnVal: String?) {
    val ruleNamesByTargetRequest = ListRuleNamesByTargetRequest {
        targetArn = topicArnVal
    }

    EventBridgeClient { region = "us-east-1" }.use { eventBrClient ->
        val response = eventBrClient.listRuleNamesByTarget(ruleNamesByTargetRequest)
        response.ruleNames?.forEach { rule ->
            println("The rule name is $rule")
        }
    }
}
