# 管理 IAM 存取金鑰
<a name="examples-iam-access-keys"></a>

## 建立存取金鑰
<a name="create-an-access-key"></a>

若要建立 IAM 存取金鑰，請使用 [https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/CreateAccessKeyRequest.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/CreateAccessKeyRequest.html) 物件呼叫 `IamClient’s``createAccessKey`方法。

**注意**  
您必須將區域設定為 **AWS\$1GLOBAL**，`IamClient`呼叫才能運作，因為 IAM 是全域服務。

 **匯入** 

```
import software.amazon.awssdk.services.iam.model.CreateAccessKeyRequest;
import software.amazon.awssdk.services.iam.model.CreateAccessKeyResponse;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
import software.amazon.awssdk.services.iam.model.IamException;
```

 **Code** 

```
    public static String createIAMAccessKey(IamClient iam,String user) {

        try {
            CreateAccessKeyRequest request = CreateAccessKeyRequest.builder()
                .userName(user).build();

            CreateAccessKeyResponse response = iam.createAccessKey(request);
           String keyId = response.accessKey().accessKeyId();
           return keyId;

        } catch (IamException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
        return "";
    }
```

請參閱 GitHub 上的[完整範例](https://github.com/awsdocs/aws-doc-sdk-examples/blob/f807d60010caf3d14fe4cd0801b842fb8e9511ca/javav2/example_code/iam/src/main/java/com/example/iam/CreateAccessKey.java)。

## 列出存取金鑰
<a name="list-access-keys"></a>

若要列出指定使用者的存取金鑰，請建立包含要列出金鑰之使用者名稱的[https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/ListAccessKeysRequest.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/ListAccessKeysRequest.html)物件，並將其傳遞給 `IamClient’s``listAccessKeys`方法。

**注意**  
如果您未提供使用者名稱給 `listAccessKeys`，則會嘗試列出與簽署請求 AWS 帳戶 之 相關聯的存取金鑰。

 **匯入** 

```
import software.amazon.awssdk.services.iam.model.AccessKeyMetadata;
import software.amazon.awssdk.services.iam.model.IamException;
import software.amazon.awssdk.services.iam.model.ListAccessKeysRequest;
import software.amazon.awssdk.services.iam.model.ListAccessKeysResponse;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
```

 **Code** 

```
    public static void listKeys( IamClient iam,String userName ){

        try {
            boolean done = false;
            String newMarker = null;

            while (!done) {
                ListAccessKeysResponse response;

            if(newMarker == null) {
                ListAccessKeysRequest request = ListAccessKeysRequest.builder()
                        .userName(userName).build();
                response = iam.listAccessKeys(request);
            } else {
                ListAccessKeysRequest request = ListAccessKeysRequest.builder()
                        .userName(userName)
                        .marker(newMarker).build();
                response = iam.listAccessKeys(request);
            }

            for (AccessKeyMetadata metadata :
                    response.accessKeyMetadata()) {
                System.out.format("Retrieved access key %s",
                        metadata.accessKeyId());
            }

            if (!response.isTruncated()) {
                done = true;
            } else {
                newMarker = response.marker();
            }
        }

        } catch (IamException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }
```

`listAccessKeys` 的結果會分頁 (每個呼叫預設最多 100 個記錄)。您可以在傳回的[https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/ListAccessKeysResponse.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/ListAccessKeysResponse.html)物件`isTruncated`上呼叫 ，以查看查詢是否傳回較少的結果，然後可用。若是如此，請在 `marker` 上呼叫 `ListAccessKeysResponse`，並將它用於建立新的請求。在下次呼叫 `listAccessKeys` 時使用該新的請求。

請參閱 GitHub 上的[完整範例](https://github.com/awsdocs/aws-doc-sdk-examples/blob/f807d60010caf3d14fe4cd0801b842fb8e9511ca/javav2/example_code/iam/src/main/java/com/example/iam/ListAccessKeys.java)。

## 擷取上次使用存取金鑰的時間
<a name="retrieve-an-access-key-s-last-used-time"></a>

若要取得上次使用存取金鑰的時間，請使用存取金鑰的 ID 呼叫 `IamClient’s``getAccessKeyLastUsed`方法 （可以使用 [https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/GetAccessKeyLastUsedRequest.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/GetAccessKeyLastUsedRequest.html) 物件傳入。

然後，您可以使用傳回的[https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/GetAccessKeyLastUsedResponse.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/GetAccessKeyLastUsedResponse.html)物件來擷取金鑰的上次使用時間。

 **匯入** 

```
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
import software.amazon.awssdk.services.iam.model.GetAccessKeyLastUsedRequest;
import software.amazon.awssdk.services.iam.model.GetAccessKeyLastUsedResponse;
import software.amazon.awssdk.services.iam.model.IamException;
```

 **Code** 

```
    public static void getAccessKeyLastUsed(IamClient iam, String accessId ){

        try {
            GetAccessKeyLastUsedRequest request = GetAccessKeyLastUsedRequest.builder()
                    .accessKeyId(accessId).build();

            GetAccessKeyLastUsedResponse response = iam.getAccessKeyLastUsed(request);

            System.out.println("Access key was last used at: " +
                    response.accessKeyLastUsed().lastUsedDate());

        } catch (IamException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
        System.out.println("Done");
    }
```

## 啟用或停用存取金鑰
<a name="iam-access-keys-update"></a>

您可以透過建立 [https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/UpdateAccessKeyRequest.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/UpdateAccessKeyRequest.html) 物件、提供存取金鑰 ID、選擇性的使用者名稱和所需的 來啟用或停用存取金鑰[https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/StatusType.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/StatusType.html)，然後將請求物件傳遞給 `IamClient’s``updateAccessKey`方法。

 **匯入** 

```
import software.amazon.awssdk.services.iam.model.IamException;
import software.amazon.awssdk.services.iam.model.StatusType;
import software.amazon.awssdk.services.iam.model.UpdateAccessKeyRequest;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
```

 **Code** 

```
       public static void updateKey(IamClient iam, String username, String accessId, String status ) {

          try {
              if (status.toLowerCase().equalsIgnoreCase("active")) {
                  statusType = StatusType.ACTIVE;
              } else if (status.toLowerCase().equalsIgnoreCase("inactive")) {
                  statusType = StatusType.INACTIVE;
              } else {
                  statusType = StatusType.UNKNOWN_TO_SDK_VERSION;
              }
              UpdateAccessKeyRequest request = UpdateAccessKeyRequest.builder()
                .accessKeyId(accessId)
                .userName(username)
                .status(statusType)
                .build();

              iam.updateAccessKey(request);

              System.out.printf(
                "Successfully updated the status of access key %s to" +
                        "status %s for user %s", accessId, status, username);

        } catch (IamException e) {
            System.err.println(e.awsErrorDetails().errorMessage());

## 刪除存取金鑰
<a name="delete-an-access-key"></a>

若要永久刪除存取金鑰，請呼叫 `IamClient’s``deleteKey`方法，提供[https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/DeleteAccessKeyRequest.html](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/iam/model/DeleteAccessKeyRequest.html)包含存取金鑰 ID 和使用者名稱的 。

**注意**  
金鑰一旦刪除，就不能再擷取或使用。若要暫時停用金鑰以便稍後再次啟用，請改用 [`updateAccessKey`](#iam-access-keys-update)方法。

 **匯入** 

```
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
import software.amazon.awssdk.services.iam.model.DeleteAccessKeyRequest;
import software.amazon.awssdk.services.iam.model.IamException;
```

 **Code** 

```
    public static void deleteKey(IamClient iam ,String username, String accessKey ) {

        try {
            DeleteAccessKeyRequest request = DeleteAccessKeyRequest.builder()
                    .accessKeyId(accessKey)
                    .userName(username)
                    .build();

            iam.deleteAccessKey(request);
            System.out.println("Successfully deleted access key " + accessKey +
                " from user " + username);

        } catch (IamException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }
```
