# 使用模擬角色
<a name="using-impersonation-roles"></a>

若要存取信箱資料，請使用 Amazon WorkMail API 動作 `AssumeImpersonationRole`。如需 Amazon WorkMail APIs的詳細資訊，請參閱 [API 參考](https://docs.aws.amazon.com/workmail/latest/APIReference/Welcome.html)。

`AssumeImpersonationRole` 傳回 `Token`。這`Token`必須在 15 分鐘內透過 HTTP 標頭 傳遞至 EWS 通訊協定`Authorization`。

下列範例示範如何搭配 EWS 通訊協定使用模擬角色。範例中使用的常數會指定組織和帳戶獨有的下列詳細資訊：
+ `{{WORKMAIL_ORGANIZATION_ID}}` – Amazon WorkMail 組織 ID
+ `{{IMPERSONATION_ROLE_ID}}` – 模擬角色 ID 
+ `{{WORKMAIL_EWS_URL}}` – [Amazon WorkMail 端點和配額提供 EWS 端點](https://docs.aws.amazon.com/general/latest/gr/workmail.html)
+ `{{EMAIL_ADDRESS}}` – 使用者信箱的電子郵件地址 

**Example Java – [EWS Java API](https://github.com/OfficeDev/ews-java-api)**  

```
import software.amazon.awssdk.services.workmail.WorkMailClient;
import software.amazon.awssdk.services.workmail.model.AssumeImpersonationRoleRequest;
import software.amazon.awssdk.services.workmail.model.AssumeImpersonationRoleResponse;

import microsoft.exchange.webservices.data.core.ExchangeService;
import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
import microsoft.exchange.webservices.data.misc.ImpersonatedUserId;
import microsoft.exchange.webservices.data.core.enumeration.misc.ConnectingIdType;

// ...

AssumeImpersonationRoleResponse response = workMailClient.assumeImpersonationRole(
    AssumeImpersonationRoleRequest.builder()
        .organizationId({{WORKMAIL_ORGANIZATION_ID}})
        .impersonationRoleId({{IMPERSONATION_ROLE_ID}})
        .build());

ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
exchangeService.setUrl(URI.create({{WORKMAIL_EWS_URL}}));
exchangeService.getHttpHeaders().put("Authorization", "Bearer " + response.token());
exchangeService.setImpersonatedUserId(new ImpersonatedUserId(ConnectingIdType.SmtpAddress, {{EMAIL_ADDRESS}}));
```

**Example .Net – [EWS 受管 API](https://github.com/OfficeDev/ews-managed-api)**  

```
using Amazon.WorkMail;
using Amazon.WorkMail.Model;

using Microsoft.Exchange.WebServices.Data;

// ...

AssumeImpersonationRoleRequest request = new AssumeImpersonationRoleRequest();
request.OrganizationId = {{WORKMAIL_ORGANIZATION_ID}};
request.ImpersonationRoleId = {{IMPERSONATION_ROLE_ID}};
AssumeImpersonationRoleResponse response = workMailClient.AssumeImpersonationRole(request);

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
service.Url = new Uri({{WORKMAIL_EWS_URL}});
service.HttpHeaders.Add("Authorization", "Bearer " + response.Token);
service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, {{EMAIL_ADDRESS}});
```

**Example Python – [Exchangelib](https://pypi.org/project/exchangelib/)**  

```
import boto3
