Azure Function 和 PowerShell：无法使用 Set-AzWebApp 设置连接字符串

Question

出于部署目的，我创建了一个 PowerShell 脚本来设置应用程序设置。这通过

$currentAppSettings = $app.SiteConfig.AppSettings

$appSettings = @{}
# Add existing App Settings
ForEach ($currentAppSetting in $currentAppSettings) {
    $appSettings[$currentAppSetting.Name] = $currentAppSetting.Value
}

# Add new App Settings
$appSettings["someKey"] = "someValue"

# Update App Settings
Set-AzWebApp -ResourceGroupName $resourceGroupName -Name $appName -AppSettings $appSettings

当我现在使用实体框架时，我还需要设置连接字符串。首先我认为这应该像应用程序设置一样工作，只需添加 ConnectionStrings 参数：

$currentConnectionStrings = $app.SiteConfig.ConnectionStrings

$connectionStrings = @{}

ForEach ($currentConnectionString in $currentConnectionStrings) {
    $connectionStrings[$currentConnectionString.Name] = $currentConnectionString.ConnectionString
}

$connectionStrings["someKey"] = "someValue"

Set-AzWebApp -ResourceGroupName $resourceGroupName -Name $appName -ConnectionStrings $connectionStrings

但这失败并出现错误

Set-AzWebApp：无法验证参数“ConnectionStrings”上的参数。连接字符串类型值对必须是“System.Collections.Hashtable”类型

尽管事实上它$connectionStrings是类型System.Collections.Hashtable

尝试使用自定义对象、数组等也失败了。

如何正确传递连接字符串？ 以及如何指定类型（例如 SQLAZURE）？

谢谢

根据 Set-AzwebApp 的文档ConnectionStrings应该是Hastable.

Set-AzWebApp
   [[-AppServicePlan] <String>]
   [[-DefaultDocuments] <String[]>]
   [[-NetFrameworkVersion] <String>]
   [[-PhpVersion] <String>]
   [[-RequestTracingEnabled] <Boolean>]
   [[-HttpLoggingEnabled] <Boolean>]
   [[-DetailedErrorLoggingEnabled] <Boolean>]
   [[-AppSettings] <Hashtable>]
   [[-ConnectionStrings] <Hashtable>]
   [[-HandlerMappings] <System.Collections.Generic.IList`1[Microsoft.Azure.Management.WebSites.Models.HandlerMapping]>]
   [[-ManagedPipelineMode] <String>]
   [[-WebSocketsEnabled] <Boolean>]
   [[-Use32BitWorkerProcess] <Boolean>]
   [[-AutoSwapSlotName] <String>]
   [-ContainerImageName <String>]
   [-ContainerRegistryUrl <String>]
   [-ContainerRegistryUser <String>]
   [-ContainerRegistryPassword <SecureString>]
   [-EnableContainerContinuousDeployment <Boolean>]
   [-HostNames <String[]>]
   [-NumberOfWorkers <Int32>]
   [-AsJob]
   [-AssignIdentity <Boolean>]
   [-HttpsOnly <Boolean>]
   [-AzureStoragePath <WebAppAzureStoragePath[]>]
   [-ResourceGroupName] <String>
   [-Name] <String>
   [-DefaultProfile <IAzureContextContainer>]
   [<CommonParameters>]

您应该connectionstring使用 a 进行设置Hashtable，如下所示：

$connectionStrings = @{connectionStrings = @{Name="<ConnectionStringName>";Value="<ConnectionSyring>";type="<SQLAzure/SQLServer/Custom/MySql>"}}

Set-AzWebApp -ResourceGroupName $resourceGroupName -Name $appName -ConnectionStrings $connectionStrings
