以下是浏览器中的有效查询(例如Firefox):
http://www.freesound.org/api/sounds/search/?q=barking&api_key=074c0b328aea46adb3ee76f6918f8fae
产生JSON文档:

我正在尝试使用Dispatch 0.9.4执行此查询。这是一个build.sbt
:
scalaVersion := "2.10.0"
libraryDependencies += "net.databinder.dispatch" %% "dispatch-core" % "0.9.4"
从sbt console
开始,我执行以下操作:
import dispatch._
val q = url("http://www.freesound.org/api/sounds/search")
.addQueryParameter("q", "barking")
.addQueryParameter("api_key", "074c0b328aea46adb3ee76f6918f8fae")
val res = Http(q OK as.String)
但承诺总是以下列错误完成:
res0: dispatch.Promise[String] = Promise(!Unexpected response status: 301!)
那么我做错了什么? Here is the API documentation以防万一。
答案 0 :(得分:13)
您可以使用configure
执行程序上的Http
方法启用重定向:
Http.configure(_ setFollowRedirects true)(q OK as.String)
你也可以手动从Location
响应中取出301
,但这样做会不太方便。
