引子
这是一篇计划外的文章。我们都知道要进行Microsoft Graph的开发的话，需要进行应用程序注册。这个在此前我已经有专门的文章写过了。但这里存在一个小的问题：国内版的Office 365在申请好之后，并没有像国际版那样，有一个对应的可以注册和管理应用程序的Azure的界面。说起来有点绕，国际版的Office 365管理员可以直接登陆到portal.azure.com进行应用程序注册和管理，但国内版却不行。这个问题目前来说还是一个know issue。不过，在帮助一些客户解决这个问题的过程中，我们也有一些变通的做法，例如我下面的这篇文章就是摘自于世纪互联技术支持的标准做法。
国内版Office 365和Azure AAD绑定的问题及解决方案
上述方案中建议客户要另外在购买一个Azure AD的订阅，然后可以跟Office 365那个Tenant绑定起来。这个从一定程度上解决了问题，但不是那么完美。本文给大家分享的是我们另外研究出来的一些经验做法。
理解Office 365与Azure AD的关系
从逻辑上说，Azure是微软的智能云平台，在这个平台上，不光是运行了全球不计其数的客户的应用程序，也承载着包括Office 365在内的规模庞大的一些SaaS平台。而Office 365的用户管理和应用管理，本质上就是用Azure AD来实现的。当然，国外的版本，Azure AD还可以做到更多，包括组织配置文件、设备管理、按条件的访问控制等等。限于篇幅，本文不对这些高级功能进行展开，我们仅仅针对用户管理和应用管理，尤其是应用管理这块来一探究竟。
本文的例子，因为主要是要演示如何解决国内版的问题，所以截图全部采用国内版Office 365或者Azure 请注意，登陆国内版本的Azure，有两种方式，一种是传统门户(manage.windowsazure.cn)，一种是新门户（portal.azure.cn)。新门户毫无疑问带来了一些新的功能，例如支持使用最新的Resource Management的方式创建和管理资源。但是，要进行Azure AD的操作的话，目前还只能在传统门户中进行
这就是我们喜闻乐见的Azure AD管理界面，用户管理不用多说了，这里可以增加和删除用户，修改用户的一些基本信息。我们重点关注的是应用管理的这个部分。
稍微简单地回顾一下相关的概念，注册应用程序（application）有两种不同类型（本机或者Web），除了提供一些基本信息（对于Web应用程序而言，关键一点在于提供ReplyUrl）之外，最重要的就是定义该应用程序需要访问的资源，以及申请的权限了。资源，在Azure AD内部的技术范畴来说，是较为ServicePrinciple的一个对象，而所谓的权限，又分为两种，一种是delegated permission，一种是application permission。前者也称为oauth权限，这是需要用户授权，并且模拟用户的身份去进行操作，适合于一些有用户交互的应用程序，而后者（也称为role权限）则适合于一些在后台运行的服务或者自动运行的脚本。
必须承认，就算是有图形化界面，要完全理解上面这些东西也多少需要一定的时间。与此同时，如果我们连图形化界面都没有的话，怎么来创建应用程序并且为其申请相关资源的权限呢，这有点挑战，但是谢天谢地，我们还是找到了一些方法。
通过PowerShell来创建应用程序并且定义服务和权限声明
我旗帜鲜明地喜欢PowerShell，尤其是用来管理Azure AD以及Office 365的时候，它总是能让我们事半功倍。为了演示下面的功能，我需要提醒你准备如下的软件环境。
请在Windows 10的机器上面，安装如下的几个组件
- 下载安装官方提供的Microsoft Online Service Sign-in Assistant for IT Professionals https://go.microsoft.com/fwlink/p/?LinkId=286152
- 下载安装官方提供的Azure Active Directory Connection http://connect.microsoft.com/site1164/Downloads/DownloadDetails.aspx?DownloadID=59185
- 请在本地用管理员身份打开PowerShell，并运行命令 Install-Module -Name AzureAD
当然，你还得需要有一个Office 365 的管理员账号信息
为了验证你是否安装成功如上的组件，请重新打开一个PowerShell窗口，运行下面的命令
$credential = Get-Credential
# 此时会弹出一个登陆框，请输入Office 365管理员和密码信息，如果没有错误请继续
Connect-AzureAD -Credential $credential -AzureEnvironmentName AzureChinaCloud
# 如果没有错误请继续
Get-AzureADApplication
查询所有的服务定义信息
我们需要通过脚本获取到当前这个Azure AD中已经定义好的服务信息
Get-AzureADServicePrincipal
正常情况下将返回下面的结果

创建应用程序
创建应用程序的PowerShell命令是New-AzureADApplication,它的详细用法请参考这里 https://docs.microsoft.com/en-us/powershell/module/azuread/new-azureadapplication?view=azureadps-2.0
$app= New-AzureADApplication -DisplayName "yourapplicationname" -ReplyUrls "https://websample.com/replyurl" -Homepage "https://websample.com" -IdentifierUris "https://websample.com"
# 这是用来创建Web应用程序的
$app= New-AzureADApplication -DisplayName "yourapplicationname" -PublicClient $true
# 这是用来创建本地应用程序的，设置PublicClient属性为true即可
$app
#请保存app的具体信息，尤其是AppId
创建密钥
如果上面创建的是Web 应用程序，还需要为应用程序创建密钥。这里会用到的PowerShell命令是New-AzureADApplicationPasswordCredential，它的详细用法请参考这里 https://docs.microsoft.com/en-us/powershell/module/azuread/new-azureadapplicationpasswordcredential?view=azureadps-2.0
New-AzureADApplicationPasswordCredential -ObjectId $app.ObjectId
# 正常情况下，将返回一个为期一年的密钥信息
CustomKeyIdentifier :
EndDate : 7/12/2018 10:25:28 AM
KeyId :
StartDate : 7/12/2017 10:25:28 AM
Value : /TD0rbE5gwm/a6TGqUhqVY46LA16rir6Zwm7pK69prI=
# 请保存这个Value信息
绑定服务和设定权限
我们已经创建了应用程序，也为他申请了一个密钥，下面就是最后也是最关键的环节————为应用程序绑定服务并且设定权限了。下面这个代码段是为上面创建好的应用程序，并且为其申请了四个delegated permission。（具体这四个权限对应的是什么，请参考上面的表格）
$graphrequest = New-Object -TypeName "Microsoft.Open.AzureAD.Model.RequiredResourceAccess"
$graphrequest.ResourceAccess = New-Object -TypeName "System.Collections.Generic.List[Microsoft.Open.AzureAD.Model.ResourceAccess]"
$ids =@("024d486e-b451-40bb-833d-3e66d98c5c73","e383f46e-2787-4529-855e-0e479a3ffac0","e1fe6dd8-ba31-4d61-89e7-88639da4683d","b340eb25-3456-403f-be2f-af7a0d370277")
foreach($id in $ids){
$obj = New-Object -TypeName "Microsoft.Open.AzureAD.Model.ResourceAccess" -ArgumentList $id,"Scope"
# 如果是AppRole权限，则第二个参数为Role
$graphrequest.ResourceAccess.Add($obj)
}
$graphrequest.ResourceAppId = "00000003-0000-0000-c000-000000000000"
Set-AzureADApplication -ObjectId $app.ObjectId -RequiredResourceAccess ($graphrequest)
# 这句命令的RequiredResourceAccess 参数中可以有多个对象
结语
这篇文章的篇幅较长，我尽可能详细地展示了很多Azure AD中注册应用程序，绑定服务和设定权限的细节，尤其是对于国内的Office 365客户以及合作伙伴来说应该有较高的实用价值。 当我们没有图形化界面可以使用的时候，你就会由衷地感慨，脚本（例如PowerShell）确实是很强大的，而且通过脚本的探索过程，你可以更加清晰地理解其背后的逻辑。
