java - Spring API 中的日志请求和响应

Question

我想使用 Spring 为 API 实现 Rest 日志记录。我试过这个:

public static String readPayload(final HttpServletRequest request) throws IOException {
      String payloadData = null;
      ContentCachingRequestWrapper contentCachingRequestWrapper = WebUtils.getNativeRequest(request, ContentCachingRequestWrapper.class);
      if (null != contentCachingRequestWrapper) {
          byte[] buf = contentCachingRequestWrapper.getContentAsByteArray();
          if (buf.length > 0) {
              payloadData = new String(buf, 0, buf.length, contentCachingRequestWrapper.getCharacterEncoding());
          }
      }
      return payloadData;
  }  

  public static String getResponseData(final HttpServletResponse response) throws IOException {
        String payload = null;
        ContentCachingResponseWrapper wrapper =
            WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        if (wrapper != null) {
            byte[] buf = wrapper.getContentAsByteArray();
            if (buf.length > 0) {
                payload = new String(buf, 0, buf.length, wrapper.getCharacterEncoding());
                wrapper.copyBodyToResponse();
            }
        }
        return payload;
    }



  @PostMapping(value = "/v1", consumes = { MediaType.APPLICATION_XML_VALUE,
      MediaType.APPLICATION_JSON_VALUE }, produces = { MediaType.APPLICATION_XML_VALUE,
          MediaType.APPLICATION_JSON_VALUE })
  public PaymentResponse handleMessage(HttpServletRequest request, HttpServletResponse response) throws Exception {


      HttpServletRequest requestCacheWrapperObject = new ContentCachingRequestWrapper(request);
      requestCacheWrapperObject.getParameterMap();

      .raw_request(readPayload(requestCacheWrapperObject))
      .raw_response(getResponseData(response))
  }

但是我的请求和响应都为 NULL。您知道从请求和响应中获取有效负载的正确方法是什么吗？

所以你只需要拥有自己的拦截器即可。

@Component
public class HttpRequestResponseLoggingInterceptorAdapter extends HandlerInterceptorAdapter {

@Autowired
private LoggingUtils loggingutils;

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
        throws Exception {
    loggingutils.preHandle(request, response);
    return true;
}

@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
        @Nullable ModelAndView modelAndView) {
    try {
        loggingutils.postHandle(request, response);
    } catch(Exception e) {
        System.out.println("Exception while logging outgoing response");
    }
}

}

完成后，您需要将新拦截器绑定(bind)到现有拦截器。

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {

@Autowired
private HttpRequestResponseLoggingInterceptorAdapter httpRequestResponseLoggingInterceptorAdapter;

@Override
public void addInterceptors(InterceptorRegistry registry) {
    registry.addInterceptor(httpRequestResponseLoggingInterceptorAdapter);
}

}

完成后，您对 handlemessage 方法的传入请求将被拦截，并且可以执行您想要的任何前/后处理。在这种情况下登录。

请告诉我这是否有帮助。
