Question

我有akkka http服务器（版本10.0）用于将邮件请求上传文件从邮递员到另一个服务（它连接亚马逊s3）

使用图片文件（图片大小= 275 KB），它有例外

akka.stream.impl.SubscriptionTimeoutException：子流源尚未在5000毫秒内实现

使用图像尺寸＆lt; 20 KB，它的工作

为什么??

这是我的代码

(post &
        entity(as[Multipart.FormData])) { (formData) =>
        val fileNamesFuture = formData.parts.mapAsync(1) { p =>
          Future.successful(p.entity, p.name, p.filename)
        }.runFold(List.empty[(BodyPartEntity, String, Option[String])])(_ :+ _)

        val req = fileNamesFuture flatMap { a => createRequestUploadImage(a.find(x => x._2 == "image").get, Url, token) }
        onComplete(req flatMap {
          HttpService.response
        }) {
          case Success(data) =>
            println(data)
            complete("OK")
        }}

制作请求方法

def createRequestUploadImage(file: (BodyPartEntity, String, Option[String]), url: String, token: Option[String] = None): Future[HttpRequest] = {
val formData =
  Multipart.FormData(
    Source.single(
      Multipart.FormData.BodyPart(
        "data",
        file._1,
        Map("filename" -> file._3.getOrElse("")))))

Marshal(formData).to[RequestEntity]
  .map(e => HttpRequest(HttpMethods.POST, uri = url, entity = e)
    .withHeaders(RawHeader("Authorization", token.getOrElse(""))))}

从其他服务获取网址（上传后）

def response(req: HttpRequest): Future[Response] = {
val connectionFlow: Flow[HttpRequest, HttpResponse, Future[Http.OutgoingConnection]] =
  Http().outgoingConnection(host = req.uri.authority.host.address(), port = req.uri.effectivePort).async

for {
  res <- Source.single(req).via(connectionFlow).runWith(Sink.head)
  data <- Unmarshal(res.entity).to[String]
} yield (res, data)}

这会对你有所帮助

将它放在application.conf文件中

100m表示100 MB

akka.http.server.parsing.max-content-length = 100m

如何以akka http 10文件大小上传文件＆gt; 100 KB
