我想用不同的内容类型代理所有类型的请求。我想出了：
private def proxy(path: String, req: Request[_]) = {
proxyRequest(path, req).map { data =>
wsResponseToPlayResponse(data)
}
}
def proxyRequest(path: String, req: Request[_]): Future[WSResponse] = {
Logger.debug(s"Method: ${req.method}")
val request = ws.url(path)
.withMethod(req.method)
.withHeaders(req.headers.headers: _*)
.withBody(req.body.toString)
request.execute()
}
private def wsResponseToPlayResponse(data: WSResponse): Result = {
val transformHeaders = data.allHeaders.map {
case (key, values) => (key, values.reduce(_ + _))
}
Result(
ResponseHeader(data.status, transformHeaders),
Enumerator(data.bodyAsBytes)
)
}
private def genLink(service: String, host: String, port: String, path: String) = path match {
case "" => s"$host:$port/api/$service"
case knownPath => s"$host:$port/api/$service/$path"
}
但它不适用于图像。所以试着这样做：
def postImage(ref:String) = Action.async(parse.raw) { req =>
ws.url(s"$BASE_URL/api/images/$ref").withHeaders(req.headers.headers:_*)
.post(req.body.asFile)
.map(wsResponseToPlayResponse)
}
但这是错误的文件，因为外部服务正在报告：

这可能很难重现。有谁知道如何制作通用代理功能？
