TrafficManagerEndpoint cmdlet：获取错误请求 (400) 和 NullReferenceExceptions

Question

我正在尝试通过 Powershell enable/disable 流量管理器端点来帮助进行环境配置。在我们的一个资源组中，cmdlet 运行良好，但我们在其他资源组中看到了一些奇怪的行为。

在一种情况下，将 TrafficManagerEndpoint 直接传递给 cmdlet（通过管道或参数）returns 400 并吐出完整的 HTML:

> $tm = Get-AzureRmTrafficManagerProfile -Name <tm-name> -ResourceGroupname <rg-name>
> $tm.Endpoints[0] | Disable-AzureRmTrafficManagerEndpoint

Confirm
Are you sure you want to disable endpoint '<tm-endpoint-name>' of Profile '<tm-name>'?

使用 Enable-AzureRmTrafficManagerEndpoint 和 Set-AzureRmTrafficManagerEndpoint 时也会发生同样的情况。

当使用资源名称调用 cmdlet 时，Diable-AzureRmTrafficManagerEndpoint 工作得很好，但是当以这种方式调用 Enable-AzureRmTrafficManagerEndpoint 时，我得到一个 NullReferenceException:

> Disable-AzureRmTrafficManagerEndpoint -Name <tm-endpoint-name> -ProfileName <tm-name> -ResourceGroupName <rg-name> -Type AzureEndpoints

Confirm

我确定名字是正确的。对此有任何见解吗？似乎我的 AzureRM.TrafficManager 模块与 Azure 不同步，但我已经尝试安装 Web 平台安装程序中可用的任何内容，但没有任何进展。（模块版本为 3.0.0）。谢谢！

根据您的描述，我们可以像这样使用 Azure PowerShell 脚本来启用或禁用流量管理器端点。

使用此脚本禁用 Azure 流量管理器端点：

PS C:\Users> $endpoint1 = Get-AzureRmTrafficManagerEndpoint -Name web1 -Type AzureEndpoints -ProfileName jasontm -ResourceGroupName jason
PS C:\Users> $endpoint1.EndpointStatus
Enabled
PS C:\Users> $endpoint1.EndpointStatus = "Disabled"
PS C:\Users> $endpoint1.EndpointStatus
Disabled
PS C:\Users> $endpoint1 | Set-AzureRmTrafficManagerEndpoint


Id                    : /subscriptions/5384xxxx-xxxx-xxxx-xxxx-xxxxe29axxxx/resourceGroups/jason/providers/Microsoft.Network/trafficManagerProfiles/jasontm/azureEndpoints/web1
Name                  : web1
ProfileName           : jasontm
ResourceGroupName     : jason
Type                  : AzureEndpoints
TargetResourceId      : /subscriptions/5384xxxx-xxxx-xxx-xxxx-xxxxe29axxxx/resourceGroups/jason/providers/Microsoft.Network/publicIPAddresses/jasonweb1-ip
Target                : jasonweb1.eastus.cloudapp.azure.com
EndpointStatus        : Disabled
Weight                : 1
Priority              : 1
Location              : East US
EndpointMonitorStatus : Disabled
MinChildEndpoints     :

使用此脚本启用 Azure 流量管理器端点：

PS C:\Users> $endpoint1 = Get-AzureRmTrafficManagerEndpoint -Name web1 -Type AzureEndpoints -ProfileName jasontm -ResourceGroupName jason
PS C:\Users> $endpoint1.EndpointStatus
Disabled
PS C:\Users> $endpoint1.EndpointStatus = "Enabled"
PS C:\Users> $endpoint1.EndpointStatus
Enabled
PS C:\Users> $endpoint1 | Set-AzureRmTrafficManagerEndpoint


Id                    : /subscriptions/5384xxxx-xxxx-xxxx-xxxx-xxxxe29axxxx/resourceGroups/jason/providers/Microsoft.Network/trafficManagerProfiles/jasontm/azureEndpoints/web1
Name                  : web1
ProfileName           : jasontm
ResourceGroupName     : jason
Type                  : AzureEndpoints
TargetResourceId      : /subscriptions/5384xxxx-xxxx-xxxx-xxxx-xxxxe29axxxx/resourceGroups/jason/providers/Microsoft.Network/publicIPAddresses/jasonweb1-ip
Target                : jasonweb1.eastus.cloudapp.azure.com
EndpointStatus        : Enabled
Weight                : 1
Priority              : 1
Location              : East US
EndpointMonitorStatus : CheckingEndpoint
MinChildEndpoints     :

顺便说一下，我使用的是 Azure PowerShell 3.7.0 版：

PS C:\Users> Get-Module -ListAvailable -Name Azure -Refresh


    Directory: C:\Program Files (x86)\Microsoft SDKs\Azure\PowerShell\ServiceManagement


ModuleType Version    Name                                ExportedCommands
