Question

在定制共享点网站时，我们使用了Share-point Hosted App Model。我在使用App Model时遇到了一个问题。

以下是我所做的步骤。

使用Visual Studio创建了一个Share-point Hosted App Model。
创建应用程序时，会有内置文件名为App.js和default.aspx
App.js文件中的代码将获取当前上下文，并在default.aspx中存在的p标记内显示当前登录人名。
此时我收到了用户名，我可以在p标签内看到它。
在default.aspx中，我添加了文本区域，按钮，文本框等控件，构建成功，我部署了解决方案。
现在，在我的共享点网站上，我创建了一个新页面并添加了应用程序部分，但未在我的页面中显示。它显示为

AppManifest文件

<AppPrincipal>
<Internal/>
</AppPrincipal>
<AppPermissionRequests AllowAppOnlyPolicy="false">
<AppPermissionRequest Scope="http://sharepoint/content/tenant" Right="Manage" />
</AppPermissionRequests>

Default.aspx的
