在HTTP服务之前添加过滤器来应用所有类型的传入HTTP请求预处理
即。
filter1 andThen httpService问题是，我想向Response添加标头。有售后服务过滤器吗？
你不能真正val addRequestHeaderFilter = new SimpleFilter[Request, Response] {
def apply(req: Request, service: Service[Request, Response]) = {
req.headerMap.add("header1","header_value")
service(req)
}
}
Http.serve(":5000", addRequestHeaderFilter andThen theActualHTTPService)
。
答案 0 :(得分：4)
我的错：我推测过滤器就像是溪流一样。所以这有效：
val addRequestHeaderFilter = new SimpleFilter[Request, Response] {
def apply(req: Request, service: Service[Request, Response]) = {
val respFuture = service(req)
respFuture.map(_.headerMap.add("header1","header_value"))
respFuture
}
}
Http.serve(":5000", addRequestHeaderFilter andThen theActualHTTPService)
在fitler中，我正在应用该服务并在返回之前操纵其响应。这就像一个预服务过滤器，也就是说，不需要反转andThen功能组合。
Finagle非常酷＆lt; 3
