在 Windows 7 中切换 IE 浏览器代理的命令？

Question

我需要尽快打开和关闭代理。

我们可以用IE 代理切换没有病毒扫描要做到这一点，但我正在寻找一个内置的命令行。

该命令行是什么？

附言

目前我必须按照下面的快照手动执行此操作。

我在 Windows 8 上使用 IE10 测试了这个脚本，作者在 Windows 8.1 上使用 Internet Explorer 11 测试了这个脚本，但我认为它也应该适用于以前的版本……它是从这里

请记住，执行脚本后必须重新启动 Internet Explorer。

# This function toggle between the following Internet Explorer Settings 
# Explicit Proxy Disabled and automatically detect proxy set to ON 
# Explicit proxy Enabled and automatically detect proxy set to OFF

#provide your proxy here 
$proxyServerToDefine = "99.99.99.99:80"

function Set-AutomaticallyDetectProxySettings ($enable) 
{ 
    # Read connection settings from Internet Explorer. 
    $regKeyPath = "HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\" 
    $conSet = $(Get-ItemProperty $regKeyPath).DefaultConnectionSettings 

    # Index into DefaultConnectionSettings where the relevant flag resides. 
    $flagIndex = 8 

    # Bit inside the relevant flag which indicates whether or not to enable automatically detect proxy settings. 
    $autoProxyFlag = 8 

    if ($enable) 
    { 
         if ($($conSet[$flagIndex] -band $autoProxyFlag) -eq $autoProxyFlag) 
        { 
        } 
        else 
        { 
            Write-Host "Enabling 'Automatically detect proxy settings'." 
             $conSet[$flagIndex] = $conSet[$flagIndex] -bor $autoProxyFlag 
            $conSet[4]++ 
            Set-ItemProperty -Path $regKeyPath -Name DefaultConnectionSettings -Value $conSet 
         } 
    } 
    else 
    { 
        if ($($conSet[$flagIndex] -band $autoProxyFlag) -eq $autoProxyFlag) 
        { 
            # 'Automatically detect proxy settings' was enabled, adding one disables it. 
            Write-Host "Disabling 'Automatically detect proxy settings'." 
            $mask = -bnot $autoProxyFlag 
             $conSet[$flagIndex] = $conSet[$flagIndex] -band $mask 
            $conSet[4]++ 
            Set-ItemProperty -Path $regKeyPath -Name DefaultConnectionSettings -Value $conSet 
        } 
    }

     $conSet = $(Get-ItemProperty $regKeyPath).DefaultConnectionSettings 
        if ($($conSet[$flagIndex] -band $autoProxyFlag) -ne $autoProxyFlag) 
        { 
            Write-Host "'Automatically detect proxy settings' is disabled." 
        } 
         else 
        { 
            Write-Host "'Automatically detect proxy settings' is enabled." 
        } 
}

$regKey="HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings" 
$proxyServer = "" 
Write-Host "Retrieve the proxy server ..." 
$proxyServer = Get-ItemProperty -path $regKey ProxyServer -ErrorAction SilentlyContinue 
Write-Host $proxyServer 
if([string]::IsNullOrEmpty($proxyServer)) 
{ 
    Write-Host "Proxy is actually disabled" 
    Set-AutomaticallyDetectProxySettings ($false) 

    Set-ItemProperty -path $regKey ProxyEnable -value 1 
    Set-ItemProperty -path $regKey ProxyServer -value $proxyServerToDefine 
    Write-Host "Proxy is now enabled" 
} 
else 
{ 
    Write-Host "Proxy is actually enabled" 
    Set-AutomaticallyDetectProxySettings ($true)

    Set-ItemProperty -path $regKey ProxyEnable -value 0 
    Remove-ItemProperty -path $regKey -name ProxyServer 
    Write-Host "Proxy is now disabled" 
}
