Question

执行下面的代码以获取Web服务器的值时，我收到此错误。

我已经阅读了一些可能的解决方案，涉及更改Web服务器上的设置，但这不是我的选择，因为我没有服务器。

错误

使用“1”参数调用“DownloadString”的异常：“服务器提交了协议违规。 Section = ResponseStatusLine“At C：\ get.ps1：28 char：60 + $ ramPage =（New-Object System.Net.WebClient）.DownloadString＆lt;＆lt;＆lt;＆lt; （“http：//”+ $ server +“/ RAM /”+ $ evalRAMStars） + CategoryInfo：NotSpecified：（:) []，MethodInvocationException + FullyQualifiedErrorId：DotNetMethodException

Powershell代码

Function Get-Performance(){
$CPU = Get-WmiObject win32_processor | Measure-Object -property LoadPercentage -Average | Select Average

$SystemInfo = Get-WmiObject -Class Win32_OperatingSystem | Select-Object Name, TotalVisibleMemorySize, FreePhysicalMemory
$perRam = (($SystemInfo.FreePhysicalMemory/1MB) / ($systeminfo.totalvisiblememorysize/1MB)) * 100
$perRam = 100 - $perRam

Write-host ("CPU:  " + $CPU.Average + "%")
Write-host ("Ram:  " + $perRam + "%")

$CPUStars = $CPU.Average / 10
$RAMStars = $perRam /10

if($CPUStars -lt 1){$CPUStars = 1}

Write-host ("{0:N0}" -f $CPUStars)
Write-host ("{0:N0}" -f $RAMStars)

$evalCPUStars = "{0:N0}" -f $CPUStars
$evalRAMStars = "{0:N0}" -f $RAMStars

$server = "10.0.0.188"

#this will get our page for later
$cpuPage = (New-Object System.Net.WebClient).DownloadString("http://" + $server + "/CPU/" + $evalCPUStars)
$ramPage = (New-Object System.Net.WebClient).DownloadString("http://" + $server + "/RAM/" + $evalRAMStars)
Write-host("http://" + $server + "/CPU/" + $evalCPUStars)
Write-host("http://" + $server + "/RAM/" + $evalRAMStars)
}

While($x -ne 0)
{
    Get-Performance
    Start-Sleep -s 10   #this will run the powershell script every 10 seconds.
}

$ evalRAMStars的值可能导致不安全的头解析阻止消息。检查其值是否有效。否则，请参阅The server committed a protocol violation. Section=ResponseStatusLine ERROR以获取更多解决方案。
