示例1: RegisterWebAPIService

/// This method needs to be called from a code behind of the SharePoint app startup page (default.aspx). It registers the calling
/// SharePoint app by calling a specific "Register" api in your WebAPI service.

/// Note:
/// Given that method is async you'll need to add the Async="true" page directive to the page that uses this method.
/// </summary>
/// <param name="page">The page object, needed to insert the services token cookie and read the querystring</param>
/// <param name="apiRequest">Route to the "Register" API</param>
/// <param name="serviceEndPoint">Optional Uri to the WebAPI service endpoint. If null then the assumption is taken that the WebAPI is hosted together with the page making this call</param>
