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

以下代码示例演示如何使用 `RemoveTargets`。

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

**适用于 .NET 的 SDK**  
 还有更多相关信息 GitHub。在 [AWS 代码示例存储库](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/dotnetv3/EventBridge#code-examples)中查找完整示例，了解如何进行设置和运行。
使用规则名称删除规则的所有目标。  

```
    /// <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**  
**移除事件的目标**  
此示例将名为 MyStream 1 的 Amazon Kinesis 直播从规则的目标中移除。 DailyLambdaFunction创建时 DailyLambdaFunction ，此直播被设置为目标，ID 为 Target1：  

```
aws events remove-targets --rule "DailyLambdaFunction" --ids "Target1"
```
+  有关 API 的详细信息，请参阅*AWS CLI 命令参考[RemoveTargets](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/events/remove-targets.html)*中的。

#### [ Java ]

**适用于 Java 的 SDK 2.x**  
 还有更多相关信息 GitHub。在 [AWS 代码示例存储库](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javav2/example_code/eventbridge#code-examples)中查找完整示例，了解如何进行设置和运行。
使用规则名称删除该规则的所有目标。  

```
    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");
        }
    }
```
