PowerShell Method for Telling NewRelic of Deployment

gistfile1.ps1

if ($OctopusEnvironmentName -eq "Production") {
	# in production, we need to
	#Create a URI instance since the HttpWebRequest.Create Method will escape the URL by default.
	$URL = "http://api.newrelic.com/deployments.xml"
	$post = "deployment[account_id]=<id here>&deployment[user]=OctopusDeploy&deployment[app_id]=<app id here>&deployment[revision]=($OctopusPackageVersion)"
	$URI = New-Object System.Uri($URL,$true)
 
	#Create a request object using the URI
	$request = [System.Net.HttpWebRequest]::Create($URI)
 
	#Build up a nice User Agent
	$request.UserAgent = $(
	"{0} (PowerShell {1}; .NET CLR {2}; {3})" -f $UserAgent, 
	$(if($Host.Version){$Host.Version}else{"1.0"}),
	[Environment]::Version,
	[Environment]::OSVersion.ToString().Replace("Microsoft Windows ", "Win")
	)
  
	# $creds = New-Object System.Net.NetworkCredential($Username,$Password)
	# $request.Credentials = $creds
 
	#Since this is a POST we need to set the method type
	$request.Method = "POST"
	$request.Headers.Add("x-api-key", "<api key here>");
 
	#Set the Content Type as text/xml since the content will be a block of xml.
	$request.ContentType = "application/x-www-form-urlencoded"
	$request.Accept = "text/xml"

	try {
		#Create a new stream writer to write the xml to the request stream.
		$stream = New-Object IO.StreamWriter $request.GetRequestStream()
		$stream.AutoFlush = $True
		$PostStr = [System.Text.Encoding]::UTF8.GetBytes($Post)
		$stream.Write($PostStr, 0,$PostStr.length)
		$stream.Close()
     
		#Make the request and get the response
		$response = $request.GetResponse()    
		$response.Close()
   
		if ([int]$response.StatusCode -eq 201) {
			Write-Host "NewRelic Deploy API called succeeded."
		} else {
			Write-Host "NewRelic Deploy API called failed."
		}
	} catch [System.Net.WebException] {
		$res = $_.Exception.Response
		 Write-Host "NewRelic Deploy API called failed." 
	}
}

thanks for the starting point

This is awesome, thanks!
Soon I'll try to do it with the Invoke-WebRequest cmdlet for posh 3+. :)
