Hi Daniel,
There are two possible solutions maybe.
C# Script to validate a URL)
PowerShell script to validate a URL)
There are two possible solutions maybe.
- Using the
.NET Script Heater
and the short below listed C# script. Very fast and recommended. In this case you have to move one
.NET Script Heater
on the Designer and copy the script below into. Now switch to the “Advanced tab” and add the following line, like the screenshot below.
using System.Net;
At least you have to connect the field containing the URLs to this Heater, the output contains the HTTP status code.
- Using the
CMD Heater
and a simple PowerShell script (geturl.ps1). In this case you have to move one
CMD Heater
on the Designer. To execute PowerShell scripts you have to use “powershell.exe” for the execute parameter. For the “Parameter” part you have to use the following line like the screenshot below.
-ExecutionPolicy bypass -File geturl.ps1 "$1"
Note: $1 will be dynamically replaced with the value off the first input parameter! The Heater output contains the HTTP status code.
C# Script to validate a URL)
Code:
public object DoWork()
{
int statuscode = 404;
// get first input parameter = url to validate
string url = (string)InValues[0].GetString();
var request = HttpWebRequest.Create(url);
request.Method = "HEAD";
try
{
using (var response = request.GetResponse() as HttpWebResponse)
{
if (response != null)
{
statuscode = Convert.ToInt32(response.StatusCode);
response.Close();
}
}
}
catch(WebException ex)
{
var response = ex.Response as HttpWebResponse;
statuscode = Convert.ToInt32(response.StatusCode);
}
return statuscode;
}
PowerShell script to validate a URL)
Code:
param([string]$url)
Write-Host -NoNewline "Check URL $url ... "
$request = [system.Net.WebRequest]::Create($url)
try
{
$response = $request.GetResponse()
}
catch [System.Net.WebException]
{
$response = $_.Exception.Response
}
Write-Host "done"
# return current http status code
exit [int]$response.StatusCode
