vertx路由器没有响应

Question

我编写了一个调度程序，它将请求路由到后端服务器，来自后端的响应是加密的。当我解密响应体并写入RoutingContext响应时。客户端无法收到响应。

代码如下

Router router;
router.routeWithRegex(patter).failureHandler(this::onFailure).handler(this::onRequest);

private void onRequest(Routing context){
  ...
  HttpClient client = vertx.createHttpClient(new HttpClientOptions());
  HttpClientRequest requestToBackend =
            client.request(method, port, backendHost, uri, backendRsp -> onBackendResponse(context, backendRsp));
  context.request().handler(body -> handleReq(requestToBackend));
  context.request().endHandler((v) -> requestToBackend.end());
}

private void onBackendResponse(RoutingContext context, io.vertx.core.http.HttpClientResponse backendRsp) {
    ....
    backendRsp.handler(data -> {
        byte[] decrypt = decrypt(data);
        context.request().response().write(data);     // this works fine
        // context.request().response().write(Buffer.buffer(decrypt)); // change to this, client can't receive response then
    });
    backendRsp.endHandler((v) -> context.request().response().end());
}

最后，我更改了响应体(比原版更短)，但没有修改标题“内容长度”。所以客户继续等..。
