Yet another "Failed to validate oauth signature and token" - scala

Question

I've this problem that many others have been through. I'm doing everything correct but still i get this annoying "Failed to validate oauth signature and token" error :)
Well, something got to be wrong I guess..
I'm trying to obtain a request_token by making a post to "https://api.twitter.com/oauth/request_token" with headers:
Authorization:
OAuth oauth_consumer_key="MYVq....................ywj2g",
oauth_nonce="m8NG0s4oc87AOIpuILafAeI1YoMv5Mu9",
oauth_signature="Bxb%252FFIfOG9KLVj%252FUNdV%252FycVlGPs%253D",
oauth_signature_method="HMAC-SHA1",
oauth_timestamp="1378976842",
oauth_version="1.0"
But it complains about signature and token.
Is my signature invalid somehow?
And for this request I dont need a token right??
I can't figure out whats wrong.
Here's some of my getRequestToken code:
val oauth_consumer_key: String = CONSUMER_KEY
val oauth_nonce: String = generateNonce()
val oauth_timestamp: String = (System.currentTimeMillis / 1000).toString
var oauth_signature: String = ""
val oauth_signature_method: String = "HMAC-SHA1"
val oauth_version: String = "1.0"
val PARAMETER_STRING: String =
"oauth_consumer_key=" + oauth_consumer_key + "&" +
"oauth_nonce=" + oauth_nonce + "&" +
"oauth_signature_method=" + oauth_signature_method + "&" +
"oauth_timestamp=" + oauth_timestamp + "&" +
"oauth_version=" + oauth_version
val BASE_STRING: String =
"POST&" + URLEncoder.encode("https://api.twitter.com/oauth/request_token", "UTF-8") + "&" + URLEncoder.encode(PARAMETER_STRING, "UTF-8")
oauth_signature = getSignature(CONSUMER_SECRET, BASE_STRING, "HmacSHA1")
val AUTHORIZATION = "OAuth " +
"oauth_consumer_key=\"" + URLEncoder.encode(oauth_consumer_key, "UTF-8") +
"\", oauth_nonce=\"" + URLEncoder.encode(oauth_nonce, "UTF-8") +
"\", oauth_signature=\"" + URLEncoder.encode(oauth_signature, "UTF-8") +
"\", oauth_signature_method=\"" + URLEncoder.encode(oauth_signature_method, "UTF-8") +
"\", oauth_timestamp=\"" + URLEncoder.encode(oauth_timestamp, "UTF-8") +
"\", oauth_version=\"" + URLEncoder.encode(oauth_version, "UTF-8") + "\""
WS.url("https://api.twitter.com/oauth/request_token").withHeaders("Authorization" -> AUTHORIZATION).post(Results.EmptyContent()).map(response => {
if(response.status != 200) Logger.error(response.body) //THIS IS WHERE I GET THE ERROR
else {
if((response.json \ "oauth_callback_confirmed").as[String] == "true") {
REQUEST_TOKEN = (response.json \ "oauth_token").as[String]
REQUEST_SECRET = (response.json \ "oauth_token_secret").as[String]
requestDone.success(true)
}
}
})
Ok so I've got everyting to work (without the oauth_callback parameter, because if I add this I get the error again).
I get the Request_token, which is valid because when I manually paste the authenticate url in the browser together with the generated request token I get redirected to twitter authenticate page and then a correct callback is made and the result is correct also. (token, token_secret, user_id and screen_name)
But my code seem to ignore my redirect to this authorize page.
requestToken_future.map { result =>
Redirect("https://api.twitter.com/oauth/authenticate?oauth_token="+REQUEST_TOKEN)
}
If I put a Logger inside the brackets it shows the log in my terminal window. But that Redirect seems to just be ignored. Never goes off.

You haven't included the oauth_callback parameter which is required. See the documentation here.
