标签: powershell azure kudu

作为CI流程的一部分,我想在部署新代码之前清除App Service上的所有日志文件。我相信最好的方法是使用PowerShell脚本进行KUDU API调用。我相信我需要传递一个命令。所以这是我到目前为止基于其他一些类似问题提出的问题。但是,当我运行此操作时,我得到一个错误403 - 此Web应用程序已停止。"回复。所以我做错了。

重要的部分是" $ kudoApiCommand"。

param(
    [string]$resourceGroupName,
    [string]$webAppName,
    [string]$slotName=""
)
function Get-AzureRmWebAppPublishingCredentials($resourceGroupName, $webAppName, $slotName = $null){
    if ([string]::IsNullOrWhiteSpace($slotName)){
        $resourceType = "Microsoft.Web/sites/config"
        $resourceName = "$webAppName/publishingcredentials"
    }
    else{
        $resourceType = "Microsoft.Web/sites/slots/config"
        $resourceName = "$webAppName/$slotName/publishingcredentials"
    }
    $publishingCredentials = Invoke-AzureRmResourceAction -ResourceGroupName 
    $resourceGroupName -ResourceType $resourceType -ResourceName 
    $resourceName -Action list -ApiVersion 2015-08-01 -Force
    Write-Host $publishingCredentials   
    return $publishingCredentials
}

function Get-KuduApiAuthorisationHeaderValue($resourceGroupName,$webAppName, $slotName = $null){
    $publishingCredentials = Get-AzureRmWebAppPublishingCredentials $resourceGroupName $webAppName $slotName
    Write-Host $publishingCredentials.Properties.PublishingUserName
    Write-Host $publishingCredentials.Properties.PublishingPassword
    return ("Basic {0}" -f [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $publishingCredentials.Properties.PublishingUserName, $publishingCredentials.Properties.PublishingPassword))))
}

function Delete-WebAppLogFiles($resourceGroupName, $webAppName, $slotName = ""){

    $kuduApiAuthorisationToken = Get-KuduApiAuthorisationHeaderValue 
    $resourceGroupName $webAppName $slotName
    if ($slotName -eq ""){
        $kuduApiUrl = "https://$webAppName.scm.azurewebsites.net/api/command"
    }
    else{
        $kuduApiUrl = "https://$webAppName`-$slotName.scm.azurewebsites.net/api/command"
    }

    $kudoApiCommand = @{
        command='del * /S /Q'
        dir='d:\\home\\LogFiles'
    }

    Write-Output $kuduApiUrl
    Write-Output $kuduApiAuthorisationToken
    Invoke-RestMethod -Uri $kuduApiUrl `
                    -Headers @{"Authorization"=$kuduApiAuthorisationToken;"If-Match"="*"} `
                    -Method POST
                    -Body $kudoApiCommand
}

Delete-WebAppLogFiles $resourceGroupName $webAppName $slotName

知道了。这对我有用:

param(
    [string]$resourceGroupName,
    [string]$webAppName,
    [string]$slotName=""
)
function Get-AzureRmWebAppPublishingCredentials($resourceGroupName, $webAppName, $slotName = $null){
    if ([string]::IsNullOrWhiteSpace($slotName)){
        $resourceType = "Microsoft.Web/sites/config"
        $resourceName = "$webAppName/publishingcredentials"
    }
    else{
        $resourceType = "Microsoft.Web/sites/slots/config"
        $resourceName = "$webAppName/$slotName/publishingcredentials"
    }
    $publishingCredentials = Invoke-AzureRmResourceAction -ResourceGroupName $resourceGroupName -ResourceType $resourceType -ResourceName $resourceName -Action list -ApiVersion 2015-08-01 -Force
    Write-Host $publishingCredentials   
    return $publishingCredentials
}
function Get-KuduApiAuthorizationHeaderValue($resourceGroupName, $webAppName, $slotName = $null){
    $publishingCredentials = Get-AzureRmWebAppPublishingCredentials $resourceGroupName $webAppName $slotName
    Write-Host $publishingCredentials.Properties.PublishingUserName
    Write-Host $publishingCredentials.Properties.PublishingPassword
    return ("Basic {0}" -f [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $publishingCredentials.Properties.PublishingUserName, $publishingCredentials.Properties.PublishingPassword))))
}
function Delete-WebAppLogFiles($resourceGroupName, $webAppName, $slotName = ""){

    $apiAuthorizationToken = Get-KuduApiAuthorizationHeaderValue $resourceGroupName $webAppName $slotName
    if ($slotName -eq ""){
        $apiUrl = "https://$webAppName.scm.azurewebsites.net/api/command"
    }
    else{
        $apiUrl = "https://$webAppName`-$slotName.scm.azurewebsites.net/api/command"
    }

    $apiCommand = @{
        #command='del *.* /S /Q /F'
        command = 'powershell.exe -command "Remove-Item -path d:\\home\\LogFiles\\* -recurse"'
        dir='d:\\home\\LogFiles'
    }

    Write-Output $apiUrl
    Write-Output $apiAuthorizationToken
    Write-Output $apiCommand
    Invoke-RestMethod -Uri $apiUrl -Headers @{"Authorization"=$apiAuthorizationToken;"If-Match"="*"} -Method POST -ContentType "application/json" -Body (ConvertTo-Json $apiCommand)

}

Delete-WebAppLogFiles $resourceGroupName $webAppName $slotName
