Question

我有一个代码可以正常工作。我希望它发送不同的结果，而不是我已有的结果。

代码：

function SpeedTest{}
C:\Users\yigal\Desktop\Tester\speedtest.exe > C:\Users\yigal\Desktop\Results\file.txt
Start-Sleep -s 45 
function Send-Email() {
    param(
        [Parameter(mandatory=$true)][string]$To
        
    )
    $username   = (Get-Content -Path 'C:\credentials.txt')[0]
    $password   = (Get-Content -Path 'C:\credentials.txt')[1]
    $secstr     = New-Object -TypeName System.Security.SecureString
    $password.ToCharArray() | ForEach-Object {$secstr.AppendChar($_)}

    $hash = @{
        from       = $username
        to         = $To
        smtpserver = "smtp.gmail.com"
        subject = Get-Date
        body = (Get-Content -Path 'C:\Users\yigal\Desktop\Results\file.txt')[7] + (Get-Content -Path 'C:\Users\yigal\Desktop\Results\file.txt')[9] 
        credential = New-Object -typename System.Management.Automation.PSCredential -argumentlist $username, $secstr
        usessl     = $true
        verbose    = $true
    }

    Send-MailMessage @hash
}
Start-Sleep -s 45
Send-Email -To "Fake@gmail.com"

此脚本通过 smtp 将其输出发送到我的邮件。如果某些字段的下载和上传速度低于 50（向下）和 5（向上），我希望它给我发送邮件。 Speedtest.exe 脚本的输出如下所示：

"

   Speedtest by Ookla

     Server: ******** - ******** (id = ********)
        ISP: ********
    Latency:    13.18 ms   (2.14 ms jitter)

   Download:    30.47 Mbps (data used: 27.1 MB)                               

     Upload:    10.04 Mbps (data used: 11.7 MB)                               
Packet Loss:     0.0%
 Result URL: https://www.speedtest.net/result/c/********
 "

我想从 speedtest.exe 输出查询下载和上传速度。

类似于：

if ($DownloadSpeed < 50 && $UploadSpeed <5 )
  {
Send-Email -To "Fake@gmail.com" -Body False
  }

我知道我需要声明 $body 但它与我尝试构建的 IF 无关。

继续我的评论，您需要继续阅读 PowerShell operators，因为在您的代码尝试中您使用的是 C# 风格的运算符。

接下来，您将函数 Send-Email 与未在此处定义的参数 -Body 一起使用。
相反，为测量的下载和上传速度添加参数：

function Send-Email {
    param(
        [Parameter(mandatory=$true)][string]$To
        [Parameter(mandatory=$true)][double]$DownloadSpeed
        [Parameter(mandatory=$true)][double]$UploadSpeed
    )
    # rest of the code (I didn't check if that works or not..)
}

要从结果文件中解析出速度值，您可以这样做：

# read the results written by the speedtest.exe as single multi-line string (use -Raw)
$speedResult = Get-Content -Path 'C:\Users\yigal\Desktop\Results\file.txt' -Raw
# test if we can parse out the values for down- and upload speed
if ($speedResult -match '(?s)Download:\s*(?<down>\d+(?:\.\d+)?) Mbps.*Upload:\s*(?<up>\d+(?:\.\d+)?) Mbps') {
    $downloadSpeed = [double]$matches['down']
    $uploadSpeed   = [double]$matches['up']
    # if down speed less than 50 AND up speed less than 5
    if ($downloadSpeed -lt 50 -and $uploadSpeed -lt 5) {
        # send your email here.
        Send-Email -To "Fake@gmail.com" -DownloadSpeed $downloadSpeed -UploadSpeed $uploadSpeed
    }
}

(?s)             The dot also matches newline characters
Download:        Match the characters “Download:” literally
\s               Match a single character that is a “whitespace character” (spaces, tabs, line breaks, etc.)
   *             Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
(?<down>         Match the regular expression below and capture its match into backreference with name “down”
   \d            Match a single digit 0..9
      +          Between one and unlimited times, as many times as possible, giving back as needed (greedy)
   (?:           Match the regular expression below
      \.         Match the character “.” literally
      \d         Match a single digit 0..9

\ Mbps           Match the characters “ Mbps” literally
