How to send twitter to twitter using Powershell?

Has anyone used the following code? How can I post a tweet? I know that I need to use " $req.Context.RawUri = [Uri]'http://api.twitter.com/version/statuses/update.xml", but I cannot get " $res = [xml][DevDefined.OAuth.Consumer.ConsumerRequestExtensions]::ReadBody($req)".

Add-Type -Path C:\OAuthDevDefined\DevDefined.OAuth.dll

$cons = New-Object devdefined.oauth.consumer.oauthconsumercontext

$cons.ConsumerKey = 'key'

$cons.ConsumerSecret = 'key'

$cons.SignatureMethod = [devdefined.oauth.framework.signaturemethod]::HmacSha1

$session = new-object DevDefined.OAuth.Consumer.OAuthSession $cons, $null, $null, $null

$accessToken = new-object DevDefined.OAuth.Framework.TokenBase

$at = import-cliXml C:\temp\myTwitterAccessToken.clixml

$accessToken.ConsumerKey, $accessToken.Realm, $accessToken.Token, $accessToken.TokenSecret = `
  $at.ConsumerKey, $at.Realm, $at.Token, $at.TokenSecret

$req = $session.Request($accessToken)

$req.Context.RequestMethod = 'GET'

$req.Context.RawUri = [Uri]'http://api.twitter.com/1/statuses/friends_timeline.xml?count=5'

$res = [xml][DevDefined.OAuth.Consumer.ConsumerRequestExtensions]::ReadBody($req)

$res.statuses.status | % { $_.user.Name }

I use OAuth and DevDefined. My function looks like this:

function Post-Twitter {
    param(
        [Parameter(Mandatory=$true)][string]$url
    )
    if (!$script:accessToken) {
        throw 'token is not initialized'
    }

  try {
    $cons = New-Object devdefined.oauth.consumer.oauthconsumercontext
    $cons.ConsumerKey = $consumerKey
    $cons.ConsumerSecret = $consumerSecret
    $cons.SignatureMethod = [devdefined.oauth.framework.signaturemethod]::HmacSha1
    $session = new-object DevDefined.OAuth.Consumer.OAuthSession `
      $cons,
      "http://twitter.com/oauth/request_token",
      "http://twitter.com/oauth/authorize",
      "http://twitter.com/oauth/access_token"
    $token = Get-AccessToken 
    $req = $session.Request($token)
    $req.Context.RequestMethod = 'POST'
    $req.Context.RawUri = new-object Uri $url
    [DevDefined.OAuth.Consumer.ConsumerRequestExtensions]::ReadBody($req)
    } catch {
    Write-Warning "Exception: $_"
    $null
  }
}

Then for simplicity, I pass the status in the query string:

add-type -assembly System.Web
$status = [system.Web.Httputility]::UrlEncode('some tweet')
Post-Twitter "http://api.twitter.com/1/statuses/update.xml?status=$status"

It seems that you know about the client key / secret and token, so I will leave it without further explanation.

Ive just posted the Powershell PEST API REST API API module on TechNet ... You can send / receive from the Twitter API! https://goo.gl/s7pmmA
