play2.0实现新浪OAuth2.0

最近有个项目要使用微博联合登录，看了下java版的 sdk， 太麻烦了，本来就不太懂java, 人都凌乱了，oauth2授权流程不是很复杂，就自己写实现下吧，就当练手了。

库代码

package libs.oauth2    import play.api.libs.concurrent._    import play.api.libs.ws._  import play.core.parsers._  import play.api.libs.json._    case class OAuthKey(key:String, secret:String)  case class AccessToken(token:String)  case class AccessTokenError(error:String, errorCode:Int, request:String)  case class OAuth2(authorizationUrl: String, accessToken: String, redirectUri: String, key:OAuthKey){    def authorization(responseType:String, params:Map[String, String]) = {      val ism = if(authorizationUrl.indexOf("?") > 0) "&" else "?"      authorizationUrl+ism+"client_id="+key.key+"&response_type="+responseType+"&redirect_uri="+java.net.URLEncoder.encode(redirectUri, "utf-8")    }        def getAccessToken(code:String):Either[AccessToken, AccessTokenError] = {      val rs = WS.url(accessToken).withQueryString(           ("client_id", key.key)          ,("client_secret", key.secret)          ,("grant_type", "authorization_code")          ,("redirect_uri", redirectUri)          ,("code", code)).post("content").value.get.body      var jsonRs = Json.parse(rs)      if(rs.indexOf("error") > 0){        Right(AccessTokenError((jsonRs \ "error").as[String],(jsonRs \ "error_code").as[Int], (jsonRs \ "request").as[String]  ))      }else{        Left(AccessToken((jsonRs \ "access_token").as[String]))      }    }        }

object login extends Controller {  val oauth2 = OAuth2(        "https://api.weibo.com/oauth2/authorize",        "https://api.weibo.com/oauth2/access_token",        "http://xx.com/login/sinare",        OAuthKey("key", "secret")        );  def sina = Action{      Redirect(oauth2.authorization("code",Map()))    }  def sinare = Action{ implicit request =>       request.queryString.getOrElse("code", "".toSeq).mkString match {        case code:String if !code.isEmpty => {          oauth2.getAccessToken(code) match{            case Left(t) => {               Ok("token:"+t.token)            }            case Right(error) => Ok("error"+error.error)          }        }        case _ => Ok("error")      }    }  }
