Question:
Has anyone used the following code? How do I make it post a tweet? I know I have to use the “$req.Context.RawUri = [Uri]'http://api.twitter.com/version/statuses/update.xml” but I can’t get the “$res = [xml][DevDefined.OAuth.Consumer.ConsumerRequestExtensions]::ReadBody($req)” right.

Answer:
I use OAuth by DevDefined as well. My function looks like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
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 status in query string:
|
1 2 3 4 |
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 consumer key/secret and the token thing, so I’ll leave it without further explanation.
