我正在使用Play的ScalaOAuth documentation中的示例代码对twitter API进行身份验证。我的完整代码在这里：
object Twitter extends Controller {
val KEY = ConsumerKey("redacted")
val TWITTER = OAuth(ServiceInfo(
"https://api.twitter.com/oauth/request_token",
"https://api.twitter.com/oauth/access_token",
"https://api.twitter.com/oauth/authorize", KEY),
true)
def authenticate = Action { request =>
request.getQueryString("oauth_verifier").map { verifier =>
val tokenPair = sessionTokenPair(request).get
// We got the verifier; now get the access token, store it and back to index
TWITTER.retrieveAccessToken(tokenPair, verifier) match {
case Right(t) => {
// We received the authorized tokens in the OAuth object - store it before we proceed
Redirect(routes.Application.timeline).withSession("token" -> t.token, "secret" -> t.secret)
}
case Left(e) => throw e
}
}.getOrElse(
TWITTER.retrieveRequestToken("http://localhost:9000/auth") match {
case Right(t) => {
// We received the unauthorized tokens in the OAuth object - store it before we proceed
Redirect(TWITTER.redirectUrl(t.token)).withSession("token" -> t.token, "secret" -> t.secret)
}
case Left(e) => throw e
})
}
def sessionTokenPair(implicit request: RequestHeader): Option[RequestToken] = {
for {
token <- request.session.get("token")
secret <- request.session.get("secret")
} yield {
RequestToken(token, secret)
}
}
}
我启动了一个我想用来搜索Twitter API的演员。我还在该文档中使用其控制器的编辑版本来执行此操作：
class TwitterParse extends Actor {
private var buildURL: String = _
private val urlBoilerPlate = "https://api.twitter.com/1.1/users/search.json?q="
private val pageCount = "&page=1&count=3"
def receive = {
case rawName: (Long, String) => {
buildURL = urlBoilerPlate + rawName._2 + pageCount
Twitter.sessionTokenPair match {
case Some(credentials) => {
WS.url(buildURL)
.sign(OAuthCalculator(Twitter.KEY, credentials))
.get
.map(result => println(result.json))
}
}
}
当我编译时，我得到：“在这里找不到任何HTTP请求标题”在Twitter.sessionTokenPair调用上。这可能与他们的文档中包含
的事实有关Action.async { implicit request =>
在调用sessionTokenPair之前。我如何解决这个问题，以便它在Actor中起作用？
