使用 akka 路由 dsl 获取 http headers
Get http headers with akka routing dsl
我是 Scala 的新手,这个问题让我很沮丧。我如何从请求中获取所有 headers?
val route = {
path("lol") {
//get httpHeaders
complete(HttpResponse())
}
}
您至少有两个选择:
a) 使用 extractRequest
指令:
val route = {
path("example") {
extractRequest { request =>
request.headers // Returns `Seq[HttpHeader]`; do anything you want here
complete(HttpResponse())
}
}
}
b) 显式访问 RequestContext
:
val route = {
path("example") { ctx =>
ctx.request.headers // Returns `Seq[HttpHeader]`; do anything you want here
ctx.complete(...)
}
}
还有一整套与 headers 相关的指令,例如 headerValueByName
或 optionalHeaderValueByName
。您可以找到详细信息 here.
