在DSC脚本中添加入站重写规则无效

正如标题所述,我正在使用以下配置反向代理功能的重写规则:

• IIS 8.5
• URL重写2.1
• Powershell 5.1

当尝试在其上设置属性时(在后面的3行上),会显示一条警告,表示无法找到入站规则,顺便说一句,还会显示正确使用的变量名)。在IIS管理控制台中,它也不可见(是的,我在上面使用了F5)。

我已经试过了:

• 在不同凭据下运行脚本
• 使用URL重写2.0
• 重新启动IIS
• 重新启动服务器

然后是脚本本身。(为了便于参考,还添加了一条出站规则):

SetScript = {
            Write-Verbose "Checking if inbound rewrite rule is present..."

            $inbound = (Get-WebConfiguration -Filter "//System.webServer/rewrite/rules" -PSPath "IIS:\Sites\$using:frontendSiteName").Collection | Where-Object {$_.Name -eq "$using:inboundRuleName"}

            if($inbound -eq $null) {
                Write-Verbose "Inbound rewrite rule not present, configuring..."

        >>>>    Add-WebConfigurationProperty -Filter "//System.webServer/rewrite/rules" -Name "." -Value @{name=$using:inboundRuleName;stopProcessing="True"} -PSPath "IIS:\Sites\$using:frontendSiteName"

            }

            Write-Verbose "Checking if outbound HTML rule is present..."

            if($outboundHTML -eq $null) {
                Write-Verbose "Outbound HTML rule not present, configuring..."

                Add-WebConfigurationProperty -Filter "//System.webServer/rewrite/outboundRules/preConditions" -Name "." -Value @{name='IsHTML'} -PSPath "IIS:\Sites\$using:frontendSiteName"
                Add-WebConfigurationProperty -Filter "//System.webServer/rewrite/outboundRules/preConditions/preCondition[@name='IsHTML']" -Name "." -Value @{input='{RESPONSE_CONTENT_TYPE}';pattern='^text/html'} -PSPath "IIS:\Sites\$using:frontendSiteName"

                Add-WebConfigurationProperty -Filter "//System.webServer/rewrite/outboundRules" -Name "." -Value @{name=$using:outboundHTMLRuleName;preCondition='IsHTML'} -PSPath "IIS:\Sites\$using:frontendSiteName"

                Add-WebConfigurationProperty -Filter "//System.webServer/rewrite/outboundRules/rule[@name='$using:outboundHTMLRuleName']/conditions" -Name "." -Value @{input='{URL}';pattern='^/api/.*'} -PSPath "IIS:\Sites\$using:frontendSiteName"

                Set-WebConfigurationProperty -Filter "//System.webServer/rewrite/outboundRules/rule[@name='$using:outboundHTMLRuleName']/action" -Name "value" -Value "/{C:1}/{R:1}" -PSPath "IIS:\Sites\$using:frontendSiteName"

                Write-Verbose "Outbound HTML rewrite rule configured"
            }
}

我希望有人知道为什么会这样,因为我在试图解决这个问题时感到非常沮丧。
