Akka Http客户端：自定义标题 [英] Akka Http Client :Custom headers

问题描述

我正在尝试使用Akka-Http来调用REST URL。我正在追踪这个示例来自akka文档。
使用这个我可以打剩下的电话。但是我不知道如何添加自定义请求标头。我尝试使用ModeledCustomHeader，但请求仍然没有标题。这是我的例子。

I am trying to use Akka-Http for invoking REST url. I am following this example from the akka documentation. Using this I am able to make the rest call. But I am not able to find out how to add custom request headers. I tried using ModeledCustomHeader, but still request is not having header. Here is my example.

final class ApiTokenHeader(token: String) extends ModeledCustomHeader[ApiTokenHeader] {
  override def renderInRequests = false
  override def renderInResponses = false
  override val companion = ApiTokenHeader
  override def value: String = token
}
object ApiTokenHeader extends ModeledCustomHeaderCompanion[ApiTokenHeader] {
  override val name = "apiKey"
  override def parse(value: String) = Try(new ApiTokenHeader(value))
}

这就是我的调用方式，

def invokeHttpRequest(cmd: WSRequestCommand) = {
    val s: HttpRequest = HttpRequest(uri = cmd.url).addHeader(ApiTokenHeader(cmd.apiKey))

    sender ! http.singleRequest(s)
  }

我尝试使用addHeaders（）代替addHeader ，但Seq（ApiTokenHeader）无法正常工作，因为它给出了编译错误。

Instead of addHeader, i tried with addHeaders(), but Seq(ApiTokenHeader) is not working as it is giving compilation error.

val s: HttpRequest = HttpRequest(uri = cmd.url, headers = Seq(ApiTokenHeader(cmd.apiKey)))

错误：（55，66）类型不匹配；找到：
Seq [com.myapp.http.core.ApiTokenHeader]必需：
scala.collection.immutable.Seq [akka.http.scaladsl.model.HttpHeader]
val s：HttpRequest = HttpRequest（uri = cmd.url，标头= Seq（ApiTokenHeader（cmd.apiKey）））
//。addHeader（ApiTokenHeader（cmd.apiKey））

Error:(55, 66) type mismatch; found : Seq[com.myapp.http.core.ApiTokenHeader] required: scala.collection.immutable.Seq[akka.http.scaladsl.model.HttpHeader] val s: HttpRequest = HttpRequest(uri = cmd.url, headers = Seq(ApiTokenHeader(cmd.apiKey))) //.addHeader(ApiTokenHeader(cmd.apiKey))

有人可以帮助我为我的请求添加多个自定义标头吗？我在这里做错了什么？

Can someone help me to add multiple custom headers for my request ? What am I doing wrong here ?

推荐答案

尝试简单地
可以将HttpMessage上的方法与RawHeaders一起使用：

try do it simply you can use the methods on HttpMessage with RawHeaders instead:

HttpRequest(GET, "/example.com/some")
   .withHeaders(
     RawHeader("X-CSRF-TOKEN", ...))
