当标头为 0时， WebFilterdoOnSuccessOrError和doAfterSuccessOrError消费者不工作。Content-Length

我有一个 WebFilter 如下：

@Bean
WebFilter webFilter() {
  return (exchange, chain) ->
      chain.filter(exchange)
          .doOnRequest(value -> {
            logger.error("webFilter" + " doOnRequest");
          })
          .doOnSuccessOrError((aVoid, throwable) -> {
            logger.error("webFilter" + " doOnSuccessOrError");
          })
          .doAfterSuccessOrError((aVoid, throwable) -> {
            logger.error("webFilter" + " doAfterSuccessOrError");
          });
}

网关使用此配置将所有流量路由到 tomcat 应用程序：

@Bean
public RouteLocator routeLocator(RouteLocatorBuilder builder) {
  return builder.routes()
      .route(r -> r.path("/**")
          .uri("http://localhost:9001").filter(gatewayFilter()))
      .build();
}

我在 Spring Boot Tomcat 应用程序上有这三个端点：

@GetMapping("/redirect")
public ModelAndView redirectWithUsingRedirectPrefix(ModelMap model) {
  return new ModelAndView("redirect:http://google.com", model);
}

@GetMapping("/empty-response")
public ResponseEntity<Void> responseEntity() {
  return ResponseEntity.ok().build();
}

@GetMapping("/foo")
public ResponseEntity<String> string() {
  return ResponseEntity.ok("foo");
}

通过网关请求/foo它按预期工作

[ctor-http-nio-2] GatewayConfiguration  : webFilter doOnRequest
[ctor-http-nio-2] GatewayConfiguration  : globalFilter doOnRequest
[ctor-http-nio-3] GatewayConfiguration  : gatewayFilter doOnRequest
[ctor-http-nio-3] GatewayConfiguration  : gatewayFilter doOnSuccessOrError
[ctor-http-nio-3] GatewayConfiguration  : globalFilter doOnSuccessOrError
[ctor-http-nio-3] GatewayConfiguration  : globalFilter doAfterSuccessOrError
[ctor-http-nio-3] GatewayConfiguration  : gatewayFilter doAfterSuccessOrError
[ctor-http-nio-2] GatewayConfiguration  : webFilter doOnSuccessOrError
[ctor-http-nio-2] GatewayConfiguration  : webFilter doAfterSuccessOrError

为了/empty-response

[ctor-http-nio-4] GatewayConfiguration  : webFilter doOnRequest
[ctor-http-nio-4] GatewayConfiguration  : globalFilter doOnRequest
[ctor-http-nio-3] GatewayConfiguration  : gatewayFilter doOnRequest
[ctor-http-nio-3] GatewayConfiguration  : gatewayFilter doOnSuccessOrError
[ctor-http-nio-3] GatewayConfiguration  : globalFilter doOnSuccessOrError
[ctor-http-nio-3] GatewayConfiguration  : globalFilter doAfterSuccessOrError
[ctor-http-nio-3] GatewayConfiguration  : gatewayFilter doAfterSuccessOrError

GlobalFilter并按GatewayFilter预期工作。但是，如您所见，webFilter doOnSuccessOrError并且webFilter doAfterSuccessOrError缺少/empty-response. /redirect端点也是如此。

您可以使用https://github.com/hisener/sc-gateway-test来重现它。
