Office365 API - 管理员访问其他用户/会议室的日历事件

Question

通过点击此请求：https://outlook.office365.com/api/v1.0/users/[e-mail]/events 浏览器中，我可以输入我的管理员用户名和密码并获取该特定房间的日历事件。但是，当我尝试从经过管理员身份验证的本机应用程序进行此调用时，我收到此响应：reason=“调用应访问 oauth 令牌中指定的邮箱。error_category=“invalid_grant” 如何获取以管理员身份验证的特定聊天室的日历事件？

这个小小的PLUG-N-COMPILE-RUN（呜呜！）Java类应该演示如何获取会议室资源用户的活动日历。Azure V2.0 REST API当前不允许这样做。确保对Exchange服务进行身份验证的身份验证用户是要检索其事件的会议室资源用户日历的“代理”。您的Exchange/Office365管理员可能需要为您设置。我在这里抓取了JavaEWSAPI：/maven2/com/microsoft/EWS-Java-API/EWS-Java API/2.0/EWS-Java-API-2.0.jar和javadoc的索引。这是一个很好的参考。如果您转到Github repo，还可以使用Maven、Gradle或其他方法将API集成到代码中：https://github.com/OfficeDev/ews-java-api.《入门指南》是……嗯……我没法说（有充分的理由）。这么说吧，你最好使用一下你的搜索引擎，以便弄清楚如何做其他事情！浏览Javadoc中的类对我帮助很大。够了，废话废话……关于代码：（哦，我包括了所有的导入！我总是讨厌当我得到一段代码样本时，我不得不去寻找和搜索导入。不过，我还是让你去连接实际的库吧！如果你能做到这一步，你就不会再穿代码尿布了！；-）

Answer 2

目前，我们只允许访问属于认证用户的邮件、日历和联系人。所以，你的场景是一个管理员访问conf。目前不支持房间日历。访问属于其他用户的资源，例如conf。房间日历在我们的支持路线图中，但我们还没有时间表与您分享。

同时，您有两种选择。

选项1:如果您能够在服务器上运行应用程序，您可以构建一个需要管理员同意的服务应用程序，但被授权访问Office 365租户中的任何邮箱。您将需要让您的本机应用程序与服务器上运行的应用程序进行对话。更多细节请看这个博客。

选项#2：您可以使用我们的Exchange Web Services SOAP API来实现您的方案。有关此选项和相关链接的更多详细信息，请参阅Office 365共享日历。
