Windows Phone-获取用户ID

Question

I need to store and share a user's list of favorites across a Windows Phone 8.1 Silverlight app, and a Windows 8.1 RT app. I have been using Roaming Settings up to this point, but it doesn't work for all connected devices. I have tested my app across a few devices and it syncs for most but not all devices. I have also received some user complaints about this too.

So instead I want to store a user's list of favorites in Azure Blob Storage, with the key being an anonymized user ID. But I can't seem to find any way of determining a user's ID. I have found information about DeviceUniqueId and there is ID_cap_identify_user capability in the manifest file for the Silverlight App (but not for the RT App) but I can't find any documentation on how to utilize this. Any help here would be apprciated.

PS - Does anyone have any theories as to why Roaming Settings isn't working correctly on some devices?

Answer 1

There is an UserInformationClass , BUT take note if you want to use it in reference to windows 10!

If you have a Windows 8 app that uses the UserInformation class, you should migrate your app to the Universal Windows Platform (UWP) and access the User class instead. Universal Windows Platform (UWP) apps that access user information are now expected to declare a new capability, uap:userAccountInformation, and call new APIs, Windows.System.User.FindAllAsync and User.GetPropertiesAsync, to get the data.

There is also an MSDN example on how to use it: https://code.msdn.microsoft.com/windowsapps/Account-picture-name-sample-912baff1
