# `RemoveTargets` 搭配 AWS SDK 或 CLI 使用
<a name="example_eventbridge_RemoveTargets_section"></a>

下列程式碼範例示範如何使用 `RemoveTargets`。

------
#### [ .NET ]

**適用於 .NET 的 SDK**  
 GitHub 上提供更多範例。尋找完整範例，並了解如何在 [AWS 程式碼範例儲存庫](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/dotnetv3/EventBridge#code-examples)中設定和執行。
使用規則名稱移除規則的所有目標。  

```
    /// <summary>
    /// Delete an event rule by name.
    /// </summary>
    /// <param name="ruleName">The name of the event rule.</param>
    /// <returns>True if successful.</returns>
    public async Task<bool> RemoveAllTargetsFromRule(string ruleName)
    {
        var targetIds = new List<string>();
        var request = new ListTargetsByRuleRequest()
        {
            Rule = ruleName
        };
        ListTargetsByRuleResponse targetsResponse;
        do
        {
            targetsResponse = await _amazonEventBridge.ListTargetsByRuleAsync(request);
            targetIds.AddRange(targetsResponse.Targets.Select(t => t.Id));
            request.NextToken = targetsResponse.NextToken;

        } while (targetsResponse.NextToken is not null);

        var removeResponse = await _amazonEventBridge.RemoveTargetsAsync(
            new RemoveTargetsRequest()
            {
                Rule = ruleName,
                Ids = targetIds
            });

        if (removeResponse.FailedEntryCount > 0)
        {
            removeResponse.FailedEntries.ForEach(e =>
            {
                _logger.LogError(
                    $"Failed to remove target {e.TargetId}: {e.ErrorMessage}, code {e.ErrorCode}");
            });
        }

        return removeResponse.HttpStatusCode == HttpStatusCode.OK;
    }
```

------
#### [ CLI ]

**AWS CLI**  
**移除事件的目標**  
此範例會將名為 MyStream1 的 Amazon Kinesis 串流移除，使其不再是規則 DailyLambdaFunction 的目標。建立 DailyLambdaFunction 時，會將此串流設為 ID 為 Target1 的目標：  

```
aws events remove-targets --rule "DailyLambdaFunction" --ids "Target1"
```
+  如需 API 詳細資訊，請參閱《AWS CLI 命令參考》**中的 [RemoveTargets](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/events/remove-targets.html)。

#### [ Java ]

**SDK for Java 2.x**  
 GitHub 上提供更多範例。尋找完整範例，並了解如何在 [AWS 程式碼範例儲存庫](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javav2/example_code/eventbridge#code-examples)中設定和執行。
使用規則名稱移除規則的所有目標。  

```
    public static void deleteTargetsFromRule(EventBridgeClient eventBrClient, String eventRuleName) {
        // First, get all targets that will be deleted.
        ListTargetsByRuleRequest request = ListTargetsByRuleRequest.builder()
                .rule(eventRuleName)
                .build();

        ListTargetsByRuleResponse response = eventBrClient.listTargetsByRule(request);
        List<Target> allTargets = response.targets();

        // Get all targets and delete them.
        for (Target myTarget : allTargets) {
            RemoveTargetsRequest removeTargetsRequest = RemoveTargetsRequest.builder()
                    .rule(eventRuleName)
                    .ids(myTarget.id())
                    .build();

            eventBrClient.removeTargets(removeTargetsRequest);
            System.out.println("Successfully removed the target");
        }
    }
```

```
suspend fun deleteTargetsFromRule(eventRuleName: String?) {
    // First, get all targets that will be deleted.
    val request =
        ListTargetsByRuleRequest {
            rule = eventRuleName
        }

    EventBridgeClient.fromEnvironment { region = "us-east-1" }.use { eventBrClient ->
        val response = eventBrClient.listTargetsByRule(request)
        val allTargets = response.targets

        // Get all targets and delete them.
        if (allTargets != null) {
            for (myTarget in allTargets) {
                val removeTargetsRequest =
                    RemoveTargetsRequest {
                        rule = eventRuleName
                        ids = listOf(myTarget.id.toString())
                    }
                eventBrClient.removeTargets(removeTargetsRequest)
                println("Successfully removed the target")
            }
