在PowerShell输出表中添加自定义值

Question

I have a list of application web URLs, wherein I am trying to monitor HTTP statuscode of the web URL by Invoke-WebRequest command method.

I got the list objects by below command:

Invoke-WebRequest https://example.com/123 | Get-Member

Here, I am using statuscode and statusdescription fields to include it in output:

Invoke-WebRequest https://example.com/123 |
    Select-Object StatusCode, StatusDescription |
    ft -a

Now I wish to include a custom name of URL in output before statuscode and statusdescription so that output will look like below

URL          StatusCode StatusDescription
---          ---------- -----------------
abc web page        200 OK

Answer 1

If you dont need to store data in variables, and just print is fine for you

$URLsources = "http://fooo/fooURL1:800","http://fooo/fooURL2:800","http://fooo/fooURL2:800"

#table definition
    $tabName = "Output table"

    #Create Table object
    $table = New-Object system.Data.DataTable “$tabName”

    #columns definition
    $col1URL = New-Object system.Data.DataColumn URL,([string])
    $col2Status = New-Object system.Data.DataColumn Status,([string])
    $col3Desc = New-Object system.Data.DataColumn Desc,([string])

    #add columns
    $table.Columns.Add($col1URL)
    $table.Columns.Add($col2Status)
    $table.Columns.Add($col3Desc)


foreach($url in $URLsources){
  $result = Invoke-WebRequest $url 

  #preparation of the row
      $row = $table.NewRow()
      $row.URL= $url
      $row.Status= $result.StatusCode
      $row.Desc= $result.StatusDescription

  #add row to the table  
  $table.Rows.Add($row)

}

#print out the table
$table | format-table -AutoSize

You can add everything to your output:

Invoke-WebRequest www.google.com | Select-Object -Property @{n="URL";e={'Any Name'}},StatusCode, StatusDescription

If you want the real url which you checked in your output you could do it like that:

Invoke-WebRequest www.google.com | Select-Object -Property @{n="URL";e={$_.BaseResponse.ResponseUri.Host}},StatusCode, StatusDescription
