java - 用于 IMAP 和 SMTP 身份验证的 Office 365 XOAUTH2 失败

问题描述

最近宣布了在 Exchange Online 中对 IMAP 和 SMTP 的 OAuth 2.0 的支持。按照指南，我设置了应用程序权限以及 IMAP 和 SMTP 连接。该应用程序被配置为Accounts in any organizational directory (Any Azure AD directory - Multitenant)并使用授权码流。

以下 URL 用于授权：

并添加了以下委派 Microsoft Graph 范围：

在此处输入图像描述

范围，来自代码的请求：

final List<String> scopes = Arrays.asList(
    "offline_access",
    "email",
    "openid",
    "profile",
    "User.Read",
    "Mail.ReadWrite",
    "https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All",
    "https%3A%2F%2Foutlook.office365.com%2FSMTP.Send"
);

我成功收到访问和刷新令牌：

{
    "token_type": "Bearer",
    "scope": "email IMAP.AccessAsUser.All Mail.ReadWrite openid profile SMTP.Send User.Read",
    "expires_in": 3599,
    "ext_expires_in": 3599,
    "access_token": "edited",
    "refresh_token": "edited",
    "id_token": "edited"
}

这是用于连接 IMAP 的代码：

Properties props = new Properties();
props.put("mail.imap.ssl.enable", "true");
props.put("mail.imaps.sasl.enable", "true");
props.put("mail.imaps.sasl.mechanisms", "XOAUTH2");
props.put("mail.imap.auth.login.disable", "true");
props.put("mail.imap.auth.plain.disable", "true");
props.put("mail.debug", "true");
props.put("mail.debug.auth", "true");

Session session = Session.getInstance(props);
session.setDebug(true);

String userEmail = "user@domain.onmicrosoft.com";
String accessToken = "access_token_received_on_previous_step";

final Store store = session.getStore("imaps");
store.connect("outlook.office365.com", 993, userEmail, accessToken);

生成以下输出：

以下代码用于连接到 SMTP：

Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth.mechanisms", "XOAUTH2");
props.put("mail.smtp.auth.login.disable","true");
props.put("mail.smtp.auth.plain.disable","true");
props.put("mail.debug.auth", "true");

Session session = Session.getInstance(props);
session.setDebug(true);

String userEmail = "user@domain.onmicrosoft.com";
String accessToken = "access_token_received_on_previous_step";

Transport transport = session.getTransport("smtp");
transport.connect("smtp.office365.com", 587, userEmail, accessToken);

它提供以下输出：

我也尝试过：

结果总是一样的。

是我做错了什么还是微软方面对此的支持存在错误？

更新1：

从命令行尝试，但结果相同：

更新 2：

尝试在 Azure 门户中创建具有以下权限的全新应用程序：

在此处输入图像描述

并在尝试同意范围时收到以下屏幕：

在此处输入图像描述

这很奇怪，因为来自 Azure 门户的权限没有指定需要管理员同意，并且我之前的应用程序注册在请求 IMAP 和 SMTP 范围时没有显示这样的屏幕。

更新 3：

感谢对这篇文章的评论，我尝试了以下范围：

public static final List<String> SCOPES = Arrays.asList(
    "offline_access",
    "https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All",
    "https%3A%2F%2Foutlook.office365.com%2FSMTP.Send"
);

这给了我下面的令牌：

{
    "token_type": "Bearer",
    "scope": "https://outlook.office365.com/IMAP.AccessAsUser.All https://outlook.office365.com/SMTP.Send",
    "expires_in": 3599,
    "ext_expires_in": 3599,
    "access_token": "eyJ0eXAiOiJKV1....",
    "refresh_token": "OAQABAAAAAAAm...."
}

IMAP/SMTP 身份验证成功，我能够阅读收件箱 + 发送电子邮件！

但是对于我的应用程序，我还需要几个其他范围来使用一些 MS Graph API 端点（读取用户配置文件、消息订阅和消息删除）。

所以我尝试了不同的范围：

public static final List<String> SCOPES = Arrays.asList(
        "offline_access",
        "User.Read",
        "Mail.ReadWrite",
        "https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All",
        "https%3A%2F%2Foutlook.office365.com%2FSMTP.Send"
);

这给出了令牌（请注意，范围值与实际工作的令牌不同，权限没有 Outlook url）：

{
    "token_type": "Bearer",
    "scope": "IMAP.AccessAsUser.All Mail.ReadWrite SMTP.Send User.Read profile openid email",
    "expires_in": 3599,
    "ext_expires_in": 3599,
    "access_token": "eyJ0eXAiOiJKV1Q...",
    "refresh_token": "OAQABAAAAAAAm..."
}

这导致了我之前得到的结果：

A1 NO AUTHENTICATE failed.

尝试将所有范围作为 URL：

public static final List<String> SCOPES = Arrays.asList(
        "offline_access", // or "https%3A%2F%2Fgraph.microsoft.com%2Foffline_access"
        "https%3A%2F%2Fgraph.microsoft.com%2FUser.Read",
        "https%3A%2F%2Fgraph.microsoft.com%2FMail.ReadWrite",
        "https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All",
        "https%3A%2F%2Foutlook.office365.com%2FSMTP.Send"
);

获取token时导致如下错误（同意步骤成功通过）：

{
    "error": "invalid_request",
    "error_description": "AADSTS28000: Provided value for the input parameter scope is not valid because it contains more than one resource. Scope offline_access https://graph.microsoft.com/user.read https://graph.microsoft.com/mail.readwrite https://outlook.office365.com/imap.accessasuser.all https://outlook.office365.com/smtp.send is not valid.\r\nTrace ID: c3282396-6231-4e11-8300-77bc2ca57f00\r\nCorrelation ID: 5f5145bf-7114-4e6c-ab11-30e7ff84a056\r\nTimestamp: 2020-05-06 08:08:48Z",
    "error_codes": [
        28000
    ],
    "timestamp": "2020-05-06 08:08:48Z",
    "trace_id": "c3282396-6231-4e11-8300-77bc2ca57f00",
    "correlation_id": "5f5145bf-7114-4e6c-ab11-30e7ff84a056"
}

并且在尝试所有范围都具有 microsoft graph 时（从 Azure 门户复制）

public static final List<String> SCOPES = Arrays.asList(
    "https%3A%2F%2Fgraph.microsoft.com%2Foffline_access",
    "https%3A%2F%2Fgraph.microsoft.com%2FUser.Read",
    "https%3A%2F%2Fgraph.microsoft.com%2FMail.ReadWrite",
    "https%3A%2F%2Fgraph.microsoft.com%2FIMAP.AccessAsUser.All",
    "https%3A%2F%2Fgraph.microsoft.com%2FSMTP.Send"
);

返回以下令牌（尽管已请求离线访问但没有刷新令牌）

{
    "token_type": "Bearer",
    "scope": "profile openid email https://graph.microsoft.com/IMAP.AccessAsUser.All https://graph.microsoft.com/Mail.ReadWrite https://graph.microsoft.com/SMTP.Send https://graph.microsoft.com/User.Read",
    "expires_in": 3599,
    "ext_expires_in": 3599,
    "access_token": "eyJ0eXAiOiJKV1..."
}

没有成功：

A1 NO AUTHENTICATE failed.

因此，如果您没有为范围指定 Outlook url，它似乎可能被假定为不允许通过 IMAP 和 SMTP 进行授权的图一。

更新 4：

通过在同意步骤中请求我需要的所有范围，然后获取仅具有 Graph 范围的第一个访问令牌和使用指定 Outlook 范围的刷新令牌端点的第二个访问令牌 - 它有效。使用刷新令牌方法来获取第二个访问令牌，因为如果您尝试通过身份验证代码获取访问令牌，您将收到以下错误：

{
    "error": "invalid_grant",
    "error_description": "AADSTS54005: OAuth2 Authorization code was already redeemed, please retry with a new valid code or use an existing refresh token.\r\nTrace ID: 09fc80f4-f5fd-4e52-938f-d56b71dd0900\r\nCorrelation ID: 4f35e05c-23c8-4fdc-a5a7-2fcde5a73b44\r\nTimestamp: 2020-05-08 12:13:30Z",
    "error_codes": [
        54005
    ],
    "timestamp": "2020-05-08 12:13:30Z",
    "trace_id": "09fc80f4-f5fd-4e52-938f-d56b71dd0900",
    "correlation_id": "4f35e05c-23c8-4fdc-a5a7-2fcde5a73b44"
}

所以不，我需要使用两个单独的令牌，具体取决于我需要管理的资源。

更新 5：

如果它仍然不起作用 - 检查您的组织是否启用了安全默认值 - 他们为帐户禁用 POP/IMAP/SMTP 身份验证 - https://techcommunity.microsoft.com/t5/exchange-team-blog/announcing-oauth- 2-0-support-for-imap-and-smtp-auth-protocols-in/bc-p/1544725/highlight/true#M28589

解决方案

IMAP、SMTP 范围针对 Exchange 资源而不是 Graph。而 User.Read、Mail.ReadWrite 则用于 Graph 资源。

我们不支持生成用于两种资源的令牌。因此错误“为输入参数范围提供的值无效，因为它包含多个资源。”

您应该通过两次调用 /token 分别生成两个令牌。1. 一个为 Exchange 资源生成的 IMAP、SMTP 范围。2. 另一个具有 Graph 范围（User.Read、Mail.ReadWrite）的，用于 Graph 资源。
