本文档仅为测试目的提供参考文档以及设计脚本范例，如您在生产环境中部署，请勿直接使用
Ø Get token
方法一（通过service principle即SPN）：
请参开如下文档：
内中有很详细的步骤，其中基本是分步执行的，即分解脚本逐步执行。
其中，
Set-AzureRmContext -SubscriptionId $subscription.subscriptionId -TenantId $subscription.TenantID
这一步中的TenantID可以在portal中，AAD->Properties中的directoryID中找到：
其次，请将其中提到的Assign the Contributor role to the service principal给位reader role：
New-AzureRmRoleAssignment -RoleDefinitionName Contributor -ServicePrincipalName $app.ApplicationId.Guid
Contributor->reader
另外，注意请将如下两个URL略作改动：
1.如果您使用第三方类curl工具，请将
curl --request POST "https://login.windows.net/[tennantid]/oauth2/token" --data-urlencode "resource=https://management.core.windows.net" --data-urlencode "client_id=[clientid]" --data-urlencode "grant_type=client_credentials" --data-urlencode "client_secret=[clientsecret]"
[/sourcecode]
这一步中的login URL改为：
https://login.chinacloudapi.cn/common/oauth2/token
2. 如果您使用power shell，请将
[sourcecode language=‘powershell‘ ]
#Azure Authtentication Token
#requires -Version 3
#SPN ClientId and Secret
$ClientID = "clientid" #ApplicationID
$ClientSecret = "ClientSecret" #key from Application
$tennantid = "TennantID"
$TokenEndpoint = {https://login.windows.net/{0}/oauth2/token} -f $tennantid
$ARMResource = "https://management.core.windows.net/";
$Body = @{
‘resource‘= $ARMResource
‘client_id‘ = $ClientID
‘grant_type‘ = ‘client_credentials‘
‘client_secret‘ = $ClientSecret
}
$params = @{
ContentType = ‘application/x-www-form-urlencoded‘
Headers = @{‘accept‘=‘application/json‘}
Body = $Body
Method = ‘Post‘
URI = $TokenEndpoint
}
$token = Invoke-RestMethod @params
$token | select access_token, @{L=‘Expires‘;E={[timezone]::CurrentTimeZone.ToLocalTime(([datetime]‘1/1/1970‘).AddSeconds($_.expires_on))}} | fl *
这一步中的
$TokenEndpoint = {https://login.windows.net/{0}/oauth2/token} -f $tennantid
URL改为https://login.chinacloudapi.cn/common/oauth2/token
结尾的-f $tenantid不变
$ARMResource =URL改为：
https://management.chinacloudapi.cn/
=====================================================================================
方法二（AAD用户名密码方式）：
通过如下函数：
## get-token 函数会获取应用的安全口令
function get-token {
??? $username = "xxxx@mcpod.partner.onmschina.cn";???? ## 订阅账号
??? $password = "xxxxx"; ????????????????????????????? ## 订阅密码
??? $client_id = "1950a258-227b-4e31-a9cf-717495945fc2"
??? $resource = "https://management.chinacloudapi.cn/"
??? $creds = @{
??????? grant_type = "password"
??????? username = $username
??????? password = $password???????
????????client_id = $client_id
??????? resource = $resource
?
??? };
?
??? $headers = $null
?
??? try
??? {
??????? $response = Invoke-RestMethod "https://login.chinacloudapi.cn/common/oauth2/token" -Method Post -Body $creds -Headers $headers;
??????? $token = $response.access_token;
??????? return $token;
??? }
??? catch
??? {
??????? $result = $_.Exception.Response.GetResponseStream();
??????? $reader = New-Object System.IO.StreamReader($result);
??????? $reader.BaseStream.Position = 0;
??????? $reader.DiscardBufferedData();
??????? $responseBody = $reader.ReadToEnd() | ConvertFrom-Json
??????? Write-Host "ERROR: $($responseBody.error)"
??????? return;
??? }
}
?
$bearer = get-token
?
???
$header = @{
??????? Authorization = "Bearer " + $bearer
??????? }
?
?
?
======================================================================================
Ø 通过token从metric api中获取需要的监控数值：
##How to
## 通过powershell，或者登陆portal查看应用程序网关的属性，获取虚拟机的resource uri，并替换如下命令中的高亮显示部分
$uri = "https://management.chinacloudapi.cn/<resource uri>/providers/microsoft.insights/metrics?api-version=2018-01-01&metricnames=TotalRequests"
?
## 调用Rest API，获取虚拟机的历史状态数据
$result = Invoke-RestMethod -Method GET -Uri $uri -Headers $header -Body $null
?
## 打印虚拟机的历史状态数据
$result.value
## 范例
以我的测试环境资源ID为例：
https://management.chinacloudapi.cn/subscriptions/test-fbfe-4f11-9af2-b81f0ee26453/resourceGroups/testresourcegroup-E/providers/Microsoft.Network/applicationGateways/TESTAPPGW/providers/microsoft.insights/metrics?api-version=2018-01-01&metricnames=TotalRequests
可以替换高亮部分为其他metric:
?
$result = Invoke-RestMethod -Method GET -Uri $uri -Headers $header -Body $null
?
$result.value
