(PowerShell) Manually Follow HTTP RedirectsDemonstrates how to manually follow redirects for an HTTP GET. Note: This example requires Chilkat v11.0.0 or greater.

The default behavior is to # automatically follow redirects. # Explicitly set FollowRedirects so that redirects are NOT automatically taken: $http.FollowRedirects = $false $resp = New-Object Chilkat.HttpResponse $success = $http.HttpNoBody("GET","http://yandex.ru/",$resp) if ($success -eq $false) { $($http.LastErrorText) exit } $status = $resp.StatusCode $("HTTP Response Status: " + $status) # The FinalRedirectUrl property will contain the redirect URL # If FollowRedirects was equal to $true, then all of the # intermediate redirects (if any) would be followed until # there were no more redirects. However, because # FollowRedirects is not $true, FinalRedirectUrl contains # the next redirect URL. $loopCount = 0 while (($status -eq 302)) { $("Redirect URL: " + $http.FinalRedirectUrl) $nextUrl = $http.FinalRedirectUrl $success = $http.HttpNoBody("GET",$nextUrl,$resp) if ($success -eq $false) { $($http.LastErrorText) exit } $status = $resp.StatusCode $("HTTP Response Status: " + $status) # For safety, prevent infinite loops by # keeping a loopCount and only allows following a max # of 10 redirects: $loopCount = $loopCount + 1 if ($loopCount -gt 10) { $("Too many redirects.") exit } } |
