如何在JAX-RS客户端中记录请求正文 [英] How to log request body in JAX-RS client

问题描述

我需要查看带有客户端JAX-RS请求的请求主体，以验证序列化工作是否正确，并将请求重新用于测试客户端，例如邮递员.

I need to see my request body with a client JAX-RS request in order to verify that the serialization works correct and reuse the request for test clients like Postman.

我知道可以使用例如resource.addFilter(new com.sun.jersey.api.client.filter.LoggingFilter());的Jersey激活日志记录.但是，我不直接使用Jersey或RESTEasy实现，而是通过JAX-RS API进行抽象:

I know it's possible to activate logging with Jersey using for example resource.addFilter(new com.sun.jersey.api.client.filter.LoggingFilter());. However, I don't use Jersey or RESTEasy implementation directly, but abstracted via JAX-RS API:

final WebTarget target = 
        ClientBuilder.newBuilder().build().target("http://localhost:8080");

如何在此处启用日志记录?

How can I enable logging here?

@peeskillet的答案 + 但是，有时JAX-RS实现不会调用摘录中的close()方法(在本例中为org.jboss.resteasy:resteasy-client-3.0.11.FINAL).

However sometimes the close() method from the snippet is not being invoked by the JAX-RS implementation (org.jboss.resteasy:resteasy-client-3.0.11.FINAL in this case).

推荐答案

JAX-RS 2.0(看起来像您正在使用的)具有

JAX-RS 2.0 (which it looks like you're using), has the ClientRequestFilter. You can register it with the Client or even the WebTarget. From the filter method, you can get the entity, and do your logging

public class LoggingFilter implements ClientRequestFilter {
    private static final Logger LOG = Logger.getLogger(LoggingFilter.class.getName());

    @Override
    public void filter(ClientRequestContext requestContext) throws IOException {
        LOG.log(Level.INFO, requestContext.getEntity().toString());
    }
}

[...]

Client client = ClientBuilder.newClient();
client.register(new LoggingFilter());
