import dispatch.classic._ val req = :/("https://accounts.google.com/o/oauth2/token").secure val params = map( "code" -> code, "client_id" -> googleclientid, "client_secret" -> googleclientsecret, "redirect_uri" -> googleauthuri, "grant_type" -> "authorization_code" ) val res = parse(h(req << params as_str)) where,
code auth code returned in pervious request https://accounts.google.com/o/oauth2/auth [step 2 on here ]
googleauthuri "https://localhost/portal/google/login" have specified in google api developer console.
also using scala , dispatch implement this.
turns out problem how dispatch finds out hostname request url. in case
val req = :/("https://accounts.google.com/o/oauth2/token").secure
dispatch interprets hostname "https://accounts.google.com/o/oauth2/token" not available , hence throws exception. counter need structure req url as,
val req = :/("accounts.google.com"/"o"/"oauth2"/"token").secure
