我可以使用SharePoint 2013应用程序吗？

Question

我真的是SharePoint 2013的新手，只在5年前在SharePoint 2007中短暂工作（所以我不记得太多）。

我现在必须计划外联网，它可能基于SharePoint 2013。

我已经阅读了有关新云应用程序模型的大量信息，但我无法弄清楚我可以使用应用程序。

我了解应用程序无法访问服务器端对象模型。但这意味着在实际术语中是什么？

例如，我们的外联网将在访问和查看的菜单上有几个自定义部分，并通过不同类型的用户查看。并且有一个能量用户，确定他的机构上的WICH人可以查看哪些部分。

这是相当复杂的，您可以看到。我可以为这种情况做一个应用吗？或者我访问无法访问的用户列表，这应该是农场解决方案？

how long is a pice of string? ;)

only joking, its a vauge question so im going to try to answer without being so vauge!

Your talking about user/group policy:

•User-only policy—This user-only policy is the authorization policy that was always applied in SharePoint 2010. When the user-only policy is used, the authorization checks take into account only the user identity. An example of when this policy is enforced is when the user is accessing resources directly without using the app.

•User + app policy—When the user + app policy is used, the authorization checks take into account both the user identity and the app identity. In particular, when this policy is used, authorization checks succeed only if both the current user and the app have sufficient permissions to perform the action in question.

An example of when this policy is used is when a SharePoint site has an embedded IFRAME that links to a Office Store app, and the app calls back to SharePoint to access SharePoint resources on behalf of the user. That is, when a Office Store app, which does not run in SharePoint Server, wants to act on behalf of the user to get access to the user's resources.

•App-only policy—When the app-only policy is used, the content database authorization checks take into account only the app identity. In particular, when this policy is used, an authorization check succeeds only if the current app has sufficient permissions to perform the action in question, regardless of the permissions of the current user (if any).

An example of when this policy is enforced is when the app is not acting on behalf of the user. An example of an app that might use this app-only policy is an expense submission app.

In the app-only policy app type, the person who installs the app (for example, a human resources manager) has the rights that the app needs, even though users who actually use the app might not have those rights.

For example, the person who installs the app allows the app to approve an expense submission that is equal to or less than $50, even though the users who submit the expense have no rights or authority to approve it. And, if the expense is more than $50, the app routes it to the appropriate manager for approval.

and also app permissions is i think what your also refering too:

SharePoint 2013 apps provide a wide variety of powerful tools and enhanced functionality that can increase the usefulness of your SharePoint 2013 deployment. When you decide to support the implementation of SharePoint 2013 apps within your deployment, you need to determine who will be installing the apps and who will be using them. You also need to determine the appropriate scope and permission levels for each app, based on how the app is intended to be used.

App permission request scopes

SharePoint 2013 apps use app permission request scopes and permission requests to specify the level at which the app is intended to run, and the permission level that is assigned to the app. The app permission request scope indicates the location within the SharePoint 2013 hierarchy where a permission request will apply. SharePoint 2013 supports the following permission request scopes:

•SPSite Defines the app permission request scope as a SharePoint 2013 site collection.

•SPWeb Defines the app permission request scope as a SharePoint 2013 web site.

•SPList Defines the app permission request scope as a SharePoint 2013 list.

•Tenancy Defines the app permission request scope as a SharePoint 2013 tenancy.

If an app is granted permission to one scope, the permission also applies to the children of that scope. For example, if an app is granted permission to a web site by using the SPWeb scope, the app is also granted permission to each list (SPList scope) that is contained within the SPWeb scope and all list items within each list. Because permission requests are made without information about the topology of the site collection where the app is installed, the scope is expressed as a type rather than as the URL of a specific instance. These scope types are expressed as URIs. Content database related permissions are organized under this URI: http://sharepoint/content. The following table provides an URI example for each app permission request scope.

What your refering to as complex is not really complex and is part of sharepoint standard practice, otherwise not many people would develop apps in the first place if there was no security involved!
