從 Azure Runbook (Powershell) 調用 Rest API 來放大和縮小 Azure Synapse 數據庫

Question

我創建了一個 Azure Powershell Runbook 以使用 Invoke-RestMethod 向上或向下擴展數據倉庫專用 SQL 池，但失敗並出現以下錯誤：

At line:31 char:11 + $Body = @ + ~ Unrecognized token in source text. At line:36 char:6 + "name" = "DW500c" + ~~~~~~ The assignment expression is not valid. The input to an assignment operator must be an object that is able to accept assignments, such as a variable or a property.

這是正在使用的代碼

$Url = "https://management.azure.com/subscriptions/$SubscriptionId/resourceGroups/$resourceGroupName/providers/Microsoft.Sql/servers/$sqlServerName/databases/$SynapseSqlPoolName?api-version=2020-08-01-preview HTTP/1.1 Content-Type: application/json; charset=UTF-8"
    $Body = @ 
        {
            location: "West Europe",
            "sku":
            {
                "name" = "DW500c"
            }
        }       

    Invoke-RestMethod -Method POST -Uri $url -Body $body -UseBasicParsing

我試圖用“：”更改“=”，但它給出了相同的錯誤

我已經嘗試使用 Mathias 提供的以下解決方案，但我收到了一個新錯誤

$Body = @{
        location = "West Europe"
        sku = @{
            name = "DW500c"
        }
    }

錯誤：

遠程服務器返回錯誤 (400) Bad Request

Invoke-RestMethod : {"error":{"code":"MissingApiVersionParameter","message":"The api-version query parameter (?api-version=) is required for all requests."}} At line:38 char:3 + Invoke-RestMethod -Method POST -Uri $url -Body $body -UseBasi ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

最新代碼但出現“指定的內容類型無效”

$Url = "https://management.azure.com/subscriptions/$SubscriptionId/resourceGroups/$resourceGroupName/providers/Microsoft.Sql/servers/$sqlServerName/databases/$SynapseSqlPoolName?api-version=2020-08-01-preview" 
    $ContentType = "HTTP/1.1 Content-Type:application/json;charset=UTF-8"
    $Body = @{
        location = "West Europe"
        sku = @{
            name = "DW500c"
        }
    }       

    Invoke-RestMethod -Method POST -Uri $url -ContentType $ContentType -Body $body -UseBasicParsing

內容類型的問題已得到修復，但我仍然收到 api 版本錯誤。 下面是完整的代碼

    Invoke-RestMethod -Method POST -Uri $url -ContentType $ContentType -Body $body -UseBasicParsing

Answer 1

我試圖用“：”更改“=”，但它給出了相同的錯誤

這是正確的做法，但請確保您也對內部sku object 使用哈希表文字 ( @{... } )：

$Body = @{
    location = "West Europe"
    sku = @{
        name = "DW500c"
    }
}

似乎您分配給$Url的字符串值包含的不僅僅是 URL - 從 URL 中刪除尾隨的 HTTP header 垃圾，然后將 Content-Type header 值傳遞給Invoke-RestMethod -ContentType

$Url = "https://management.azure.com/subscriptions/$SubscriptionId/resourceGroups/$resourceGroupName/providers/Microsoft.Sql/servers/$sqlServerName/databases/$SynapseSqlPoolName?api-version=2020-08-01-preview" 
$ContentType = 'application/json;charset=UTF-8'

# ...

Invoke-RestMethod -Method POST -Uri $url -ContentType $ContentType -Body $body -UseBasicParsing

Answer 2

感謝 Mathias R.Jessen 的指導，感謝我審查過的 100 個網站以及今天進行的 100 次或更多次測試，我終於找到了讓它工作的方法。 我們需要記住，正常的 Azure 數據庫與 Synapse 數據庫（我的是 Synapse DB）有不同的 URL。

可以對代碼進行更多調整，例如自動獲取 subscriptionId 和 apiversion 而不是對其進行硬編碼，還可以使用一些 try、catch 和 IF 條件在未暫停但代碼時對 Synapse DB 進行縮放下面完成使用 Azure 中的 Powershell Runbook 擴展和縮小 Snapse DB 所需的操作（調用 API）
