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

问题描述

我正在尝试使用 Akka-Http 来调用 REST url.我正在关注 这个 来自 akka 文档的例子.使用它，我可以拨打其余的电话.但我不知道如何添加自定义请求标头.我尝试使用 ModeledCustomHeader，但请求仍然没有标头.这是我的例子.

final class ApiTokenHeader(token: String) extends ModeledCustomHeader[ApiTokenHeader] {覆盖 def renderInRequests = false覆盖 def renderInResponses = false覆盖 val 伴侣 = ApiTokenHeader覆盖定义值:字符串 = 令牌}object ApiTokenHeader extends ModeledCustomHeaderCompanion[ApiTokenHeader] {覆盖 val 名称 = "apiKey"覆盖 def parse(value: String) = Try(new ApiTokenHeader(value))}

这就是我调用的方式，

def invokeHttpRequest(cmd: WSRequestCommand) = {val s: HttpRequest = HttpRequest(uri = cmd.url).addHeader(ApiTokenHeader(cmd.apiKey))发件人！http.singleRequest(s)}

我尝试使用 addHeaders() 而不是 addHeader，但是 Seq(ApiTokenHeader) 无法正常工作，因为它给出了编译错误.

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

<块引用>

错误:(55, 66) 类型不匹配；成立 :Seq[com.myapp.http.core.ApiTokenHeader] 需要: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?

解决方案

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

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

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))
}

This is how I am invoking,

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

    sender ! http.singleRequest(s)
  }

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)))

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))

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

解决方案

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

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