See http://technet.microsoft.com/en-us/library/hh849901.aspx for details. .PARAMETER Uri Uniform Resource Identifier .PARAMETER Method Get/Post .PARAMETER Body Request body .PARAMETER ContentType Content type .PARAMETER SessionVariable Session variable .PARAMETER TimeoutSec Timeout in seconds .PARAMETER Credential Credentials .PARAMETER UseDefaultCredentials Set if you want default credentials .PARAMETER WebSession Web session .PARAMETER OutFile Saves the response body in the specified output file .PARAMETER Proxy Uses a proxy server for the request, rather than connecting directly to the Internet resource. Enter the URI of a network proxy server. .PARAMETER FailOnErrorResponse If true and response is not OK, an exception will be thrown (default Invoke-WebRequest behavior). Otherwise, normal response will be returned. .EXAMPLE Invoke-WebRequestWrapper "http://www.google.com" "Get" $body $contentType #> [CmdletBinding()] [OutputType([void])] param( [Parameter(Mandatory=$true)] [uri] $Uri, [Parameter(Mandatory=$false)] [string] $Method, [Parameter(Mandatory=$false)] [object] $Body, [Parameter(Mandatory=$false)] [string] $ContentType, [Parameter(Mandatory=$false)] [string] $SessionVariable, [Parameter(Mandatory=$false)] [int] $TimeoutSec, [Parameter(Mandatory=$false)] [System.Management.Automation.PSCredential] $Credential, [Parameter(Mandatory=$false)] [switch] $UseDefaultCredentials, [Parameter(Mandatory=$false)] [object] $WebSession, [Parameter(Mandatory=$false)] [object] $OutFile, [Parameter(Mandatory=$false)] [Uri] $Proxy, [Parameter(Mandatory=$false)] [switch] $FailOnErrorResponse = $true ) $msg = "Issuing HTTP request: {0} {1}" -f $Method.ToString(), $Uri if ($contentType) { $msg += ", contentType=$contentType" } if ($useDefaultCredentials) { $msg += (", using default Windows credentials (user: '{0}')" -f (Get-CurrentUser)) } Write-Log -Info $msg if ($body) { Write-Log -_debug "Body: $Body" } [void]($PSBoundParameters.Remove('FailOnErrorResponse')) try { Invoke-WebRequest @PSBoundParameters } catch { $response = $_.Exception.Response if (!$response) { Write-ErrorRecord -StopExecution -Message ("HTTP request failed with no response data.") } else { if ($FailOnErrorResponse) { Write-ErrorRecord -StopExecution -Message ("HTTP request failed with code {0} ({1}).`n RawContent: {2}" -f [int]$response.StatusCode, $response.StatusDescription, $response.RawContent) } else { $response } } } if ($sessionVariable) { # Need to rescope the session variable to parent scope $val = (Get-Variable $SessionVariable).Value Set-Variable -Name $SessionVariable -Scope 2 -Value $val } } |
