android – Outlook – 读取另一个用户的日历
作者:互联网
我正在开发基于Outlook-SDK-Android的Android应用程序.该应用程序与Outlook Calendar REST API进行对话以检索,预订和删除事件(请参阅代码示例here和here).现在我需要阅读其他人的日历,并且我已经向其他用户提供了具有委托访问权限(author permission level)的Office365帐户.
我已经使用new portal上提供的帐户注册了我的应用程序.在我的应用程序中,我使用范围“https://outlook.office.com/Calendars.ReadWrite”.
(该范围在com.microsoft.aad.adal.AuthenticationContext.acquireToken()中用于初始化Office REST Client for Android OutlookClient,即orc-for-android提供的共享客户端堆栈)
当我尝试读取我有委托访问权限的另一个用户的日历时,我只收到403响应:
{
"error": {
"code": "ErrorAccessDenied",
"message": "Access is denied. Check credentials and try again."
}
}
有帮助吗?
这是API的限制吗?如果是这样,为什么提供以下方法调用链呢?
outlookClient.getUsers()
.getById("meetingRoom@company.com")
.getCalendarView()
更新:
似乎正在进行的工作将允许这种情况,如下所述:Office 365 REST API – Access meeting rooms calendars
因此,如果在这方面取得进展,我可以在不使用“admin service app”的情况下实现我的目标吗? (见Office 365 API or Azure AD Graph API – Get Someone Elses Calendar)
我可以使用here建议的基本身份验证吗?
解决方法:
日历委派是Exchange的一项功能,Graph API和Outlook API不允许用户访问委派的日历.
目前,替代解决方法可以使用EWS.以下是供您参考的示例:
static void DelegateAccessSearchWithFilter(ExchangeService service, SearchFilter filter)
{
// Limit the result set to 10 items.
ItemView view = new ItemView(10);
view.PropertySet = new PropertySet(ItemSchema.Subject,
ItemSchema.DateTimeReceived,
EmailMessageSchema.IsRead);
// Item searches do not support deep traversal.
view.Traversal = ItemTraversal.Shallow;
// Define the sort order.
view.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending);
try
{
// Call FindItems to find matching calendar items.
// The FindItems parameters must denote the mailbox owner,
// mailbox, and Calendar folder.
// This method call results in a FindItem call to EWS.
FindItemsResults<Item> results = service.FindItems(
new FolderId(WellKnownFolderName.Calendar,
"fx@msdnofficedev.onmicrosoft.com"),
filter,
view);
foreach (Item item in results.Items)
{
Console.WriteLine("Subject: {0}", item.Subject);
Console.WriteLine("Id: {0}", item.Id.ToString());
}
}
catch (Exception ex)
{
Console.WriteLine("Exception while enumerating results: { 0}", ex.Message);
}
}
private static void GetDeligateCalendar(string mailAddress, string password)
{
ExchangeService service = new ExchangeService();
service.Credentials = new WebCredentials(mailAddress, password);
service.TraceEnabled = true;
service.TraceFlags = TraceFlags.All;
service.AutodiscoverUrl(mailAddress, RedirectionUrlValidationCallback);
SearchFilter sf = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(AppointmentSchema.Subject, "Discuss the Calendar REST API"));
DelegateAccessSearchWithFilter(service, sf);
}
