Spring WebClient - 记录 Uri 和响应方法

Question

我已经定义了WebClient:

  @Bean
  WebClient myWebClient() {
    return WebClient.builder()
        .baseUrl(baseUrl)
        .filter(logRequest())
        .filter(logResponse())
        .build();
  }

  private ExchangeFilterFunction logRequest() {
    return ExchangeFilterFunction.ofRequestProcessor(clientRequest -> {
      log.info("MY_WEB_CLIENT | Performing {} {} request", clientRequest.method(), clientRequest.url());
      return Mono.just(clientRequest);
    });
  }

  private ExchangeFilterFunction logResponse() {
    return ExchangeFilterFunction.ofResponseProcessor(clientResponse -> {
      log.info("MY_WEB_CLIENT | Respond with {} status code", clientResponse.rawStatusCode());
      return Mono.just(clientResponse);
    });
  }

在logResponse 过滤方法中，我记录响应httpStatusCode，但我还想在执行请求的地方添加httpMethod + uri。我知道我可以在请求之前访问这些数据（使用ExchangeFilterFunction.ofRequestProcessor()），但是有没有办法将这些数据添加到我的logResponse 过滤器中？

找到路了：

private static ExchangeFilterFunction log() {
    return (ClientRequest request, ExchangeFunction next) -> {
      log.info("MY_WEB_CLIENT | Performing {} {} request", request.method(), request.url());
      return next.exchange(request)
          .doOnNext((ClientResponse response) -> {
            log.info("MY_WEB_CLIENT | {} {} Respond with {} status code",request.method(), request.url(),
                response.rawStatusCode());
          });
    };
