# 将 `DeleteServiceLinkedRole` 与 AWS SDK 或 CLI 配合使用
<a name="iam_example_iam_DeleteServiceLinkedRole_section"></a>

以下代码示例演示如何使用 `DeleteServiceLinkedRole`。

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

**AWS CLI**  
**删除服务相关角色**  
以下 `delete-service-linked-role` 示例将删除您不再需要的指定服务相关角色。删除操作异步进行。您也可以使用 `get-service-linked-role-deletion-status` 命令查看删除状态并确认何时删除。  

```
aws iam delete-service-linked-role \
    --role-name AWSServiceRoleForLexBots
```
输出：  

```
{
    "DeletionTaskId": "task/aws-service-role/lex.amazonaws.com/AWSServiceRoleForLexBots/1a2b3c4d-1234-abcd-7890-abcdeEXAMPLE"
}
```

// RoleWrapper encapsulates AWS Identity and Access Management (IAM) role actions
// used in the examples.
// It contains an IAM service client that is used to perform role actions.
type RoleWrapper struct {
	IamClient *iam.Client
}



// DeleteServiceLinkedRole deletes a service-linked role.
func (wrapper RoleWrapper) DeleteServiceLinkedRole(ctx context.Context, roleName string) error {
	_, err := wrapper.IamClient.DeleteServiceLinkedRole(ctx, &iam.DeleteServiceLinkedRoleInput{
		RoleName: aws.String(roleName)},
	)
	if err != nil {
		log.Printf("Couldn't delete service-linked role %v. Here's why: %v\n", roleName, err)
	}
	return err
}
