如何使用scala喷雾分离器？ [英] how to use scala spray detach?
问题描述
我正在尝试使用喷雾分离器，如下所示：
i'm trying to use spray detach as following:
path("") {
get {
detach {
respondWithMediaType(`text/html`) { // XML is marshalled to `text/xml` by default, so we simply override here
complete {
<html>
<body>
<h1>Say hello to <i>spray-routing</i> on <i>Jetty</i>!</h1>
</body>
</html>
}
}
}
}
}
，但出现以下编译错误：
but i get following compilation error:
类型不匹配；找到：spray.routing.RequestContext =>需要的单位
：spray.routing.directives.DetachMagnet
responseWithMediaType（text / html）{// XML默认情况下被编组为text / xml，因此我们只需在此处覆盖
^
type mismatch; found : spray.routing.RequestContext => Unit required: spray.routing.directives.DetachMagnet respondWithMediaType(
text/html) { // XML is marshalled totext/xmlby default, so we simply override here ^
我查看了： https://github.com/spray/spray/wiki/分离，我仍然不知道我在做什么错...
I looked at: https://github.com/spray/spray/wiki/Detach and I still have no idea what i'm doing wrong...
推荐答案
不推荐使用的文档。如果要阅读当前文档，则必须查看 spray.io 网站。
You are looking at a deprecated documentation. If you to want to read the current documentation you have to look at the spray.io website.
关于您的问题，当前文档为 detach 指令指定了不同的签名-请参阅此处
Regarding your problem, the current documentation specifies a different signature for the detach directive - see here
def detach()(implicit ec: ExecutionContext): Directive0
def detach()(implicit refFactory: ActorRefFactory): Directive0
def detach(ec: ExecutionContext): Directive0
当我隐式传递ExecutionContext时，您必须写上括号：
As you are passing your ExecutionContext implicitly I guess, you have to write the parenthesis:
detach() {
respondWithMediaType(`text/html`) { // XML is marshalled to `text/xml` by default, so we simply override here
complete { ...
