身份驗證上下文令牌緩存未定義

Question

我試圖將無聲身份驗證實現到Sharepoint Online到我的應用程序中。我已經添加了Office365連接的服務。我正在使用一個測試頁面，它使用令牌和失效日期來填充2個文本框。我有以下代碼（非無聲AUTH）的作品就好了：

document.addEventListener('deviceready', function() { 
$(document).ready(function() { 
    var authContext = Microsoft.ADAL.AuthenticationContext; 
    authContext.createAsync("https://login.microsoftonline.com/common/") 
     .then(function (authContext) { 
      authContext.acquireTokenAsync(
       "https://my.sharepoint.com",  // Resource URI 
       "4be098f8-2184-4831-9ef7-3d17dbbef6a0",  // Client ID 
       "http://localhost:4400/services/office365/redirectTarget.html" // Redirect URI 
      ).then(function (authResult) { 
       $('#token').value = authResult.accessToken; 
       $('#expire').value = authResult.expiresOn; 
      }, function (err) { 
       console.log(err); 
      }); 
     }, function (err) { 
      console.log(err); 
     }); 
}); 
}); 

我則想實現無聲AUTH使用下面的代碼：當試圖

document.addEventListener('deviceready', function() { 
$(document).ready(function() { 
    var authContext = Microsoft.ADAL.AuthenticationContext; 
    authContext.tokenCache.readItems().then(function (items) { 
     if (items.length > 0) { 
      authority = items[0].authority; 
      authContext = new Microsoft.ADAL.AuthenticationContext(authority); 
     } 
     authContext.acquireTokenSilentAsync("https://my.sharepoint.com", "4be098f8-2184-4831-9ef7-3d17dbbef6a0").then 
     (function (authResult) { 
      $('#token').value = authResult.accessToken; 
      $('#expire').value = authResult.expiresOn; 
     }, 
     function (authContext) { 
      authContext.acquireTokenAsync(
       "https://my.sharepoint.com",  // Resource URI 
       "4be098f8-2184-4831-9ef7-3d17dbbef6a0",  // Client ID 
       "http://localhost:4400/services/office365/redirectTarget.html" // Redirect URI 
      ).then(function (authResult) { 
       $('#token').value = authResult.accessToken; 
       $('#expire').value = authResult.expiresOn; 
      }, function (err) { 
       console.log(err); 
      }); 
     }, function (err) { 
      console.log(err); 
     } 
     ) 
    }); 
}); 
}); 

我收到錯誤讀取令牌緩存，我得到的未定義的令牌緩存。我看過的每個示例都提到了令牌緩存，所以只是想知道它爲什麼會不明確？

我需要創建async my authContext對象，然後才能訪問tokenCache ...哎呦
