如何在Dropwizard 1.0.2中使用LoggingFeature打印服务器响应?

问题描述

以下代码导致在Dropwizard 0.9.2和1.0.2中打印JSON服务器响应:

The following code results in JSON server responses being printed in Dropwizard 0.9.2 and 1.0.2:

return ClientBuilder
        .newBuilder()
        .build()
        .register(new LoggingFilter(Logger.getLogger(LoggingFilter.class.getName()), true))

例如:

Oct 21, 2016 7:57:42 AM org.glassfish.jersey.filter.LoggingFilter log
INFO: 1 * Client response received on thread main
1 < 401
1 < Connection: keep-alive
1 < Content-Length: 49
1 < Content-Type: text/plain
1 < Date: Fri, 21 Oct 2016 07:57:42 GMT
1 < Server: […]
1 < WWW-Authenticate: Basic realm="[…]"
Credentials are required to access this resource.

javax.ws.rs.NotAuthorizedException: HTTP 401 Unauthorized

但是，在1.0.2中不推荐使用LoggingFilter，建议改用LoggingFeature.在 LoggingFeature文档中说默认的详细程度是LoggingFeature.Verbosity.PAYLOAD_TEXT，所以我期望以下代码仍能在Dropwizard 1.0.2中打印JSON服务器响应:

However, LoggingFilter is deprecated in 1.0.2, and it's recommended to use LoggingFeature instead. In the documentation of LoggingFeature it says that the default verbosity is LoggingFeature.Verbosity.PAYLOAD_TEXT, so I was expecting the following code to still print JSON server responses in Dropwizard 1.0.2:

return ClientBuilder
        .newBuilder()
        .build()
        .register(new LoggingFeature(Logger.getLogger(getClass().getName())))

相反，日志仅包含以下内容:

Instead the log contains just this:

javax.ws.rs.NotAuthorizedException: HTTP 401 Unauthorized

推荐答案

这可以解决问题:

new LoggingFeature(Logger.getLogger(getClass().getName()), Level.OFF, LoggingFeature.Verbosity.PAYLOAD_TEXT, 8192)

我猜想客户端中的日志记录功能就像一个过滤器，而不是预期的包含功能.

I'm guessing the logging feature in the client acts like a filter, rather than as an include as expected.
