试图让一个 spray 端点协商邮递员对内容的请求。我的 XML 封送器似乎让我失望,即,它永远不会根据 Accept 标头和字符集解析正确的封送器选项。
我有以下几点:
object ResponseVO {
val NodeSeqMarshaller = Marshaller.delegate[ResponseVO, NodeSeq](ContentType(`text/xml`, `UTF-8`)) { respVO => <ussd><type>{ respVO.respType }</type><message>{ respVO.message }</message></ussd> }
val supportedContentTypes = List[ContentType](ContentType(`text/xml`, `UTF-8`))
implicit val marshaller = Marshaller[ResponseVO] { (respVO, ctx) =>
ctx.tryAccept(supportedContentTypes) match {
case Some(ContentType(`text/xml`, `UTF-8`)) => NodeSeqMarshaller(respVO, ctx)
case whatever => println(whatever); ctx.rejectMarshalling(supportedContentTypes);
}
}
}
和以下路线:
trait USSDRoute {
this: SimpleRoutingApp with BootStrappedActorSystem =>
val ussdRoute = path("ussd") {
parameters('msisdn.as[Long], 'session.as[String], 'type.as[Int], 'msg.as[String], 'network.as[Int]) { (msisdn, session, reqType, msg, network) =>
complete {
val reqVO = RequestVO(msisdn, session, reqType, msg, network)
println(s"received $reqVO")
ResponseVO(1, "Spirit midget medium escapes from prison, headlines read: Small medium at large!")
}
}
}
}
不幸的是,我似乎从来没有正确谈判过,即,我的编组器分辨率会将炸弹潜入"任何"块并以 406 响应
"Resource representation is only available with these Content-Types:
text/xml; charset=UTF-8"
我正在使用邮递员,我的请求标头为:
GET /ussd?msisdn=0794138690&type=1&network=4&msg=hello&session=99 HTTP/1.1
Host: localhost:9999
Connection: keep-alive
Accept: text/xml; charset=UTF-8
Cache-Control: no-cache
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML,
like Gecko) Chrome/40.0.2214.91 Safari/537.36
Accept-Encoding: gzip, deflate, sdch
Accept-Language: en-US,en;q=0.8,nl;q=0.6
这可能是一件小而愚蠢的事情 - 希望有人可以帮助引导我朝着正确的方向前进。
谢谢
看看案例类ContentType
是如何定义的:
case class ContentType(mediaType: MediaType, definedCharset: Option[HttpCharset])
请注意,definedCharset
被定义为Option[HttpCharset]
,因此您的模式匹配通过
case Some(ContentType(`text/xml`, `UTF-8`)) => ...
永远不可能成功。因此,您需要使用Some
来成功执行模式匹配:
case Some(ContentType(`text/xml`, Some(`UTF-8`))) => ...
