我想以编程方式启用/禁用登录。我试过了
启用：

client.property ( LoggingFeature.LOGGING_FEATURE_VERBOSITY_CLIENT, LoggingFeature.Verbosity.PAYLOAD_ANY ); 
client.property ( LoggingFeature.LOGGING_FEATURE_LOGGER_LEVEL_CLIENT,  "INFO");

禁用：

client.property ( LoggingFeature.LOGGING_FEATURE_VERBOSITY_CLIENT,  null) ;
    client.property ( LoggingFeature.LOGGING_FEATURE_LOGGER_LEVEL_CLIENT,  null);

但运气不好。日志记录本身是有效的。
属性更改时是否必须重新创建客户端？
有人有线索吗？
向格里问好
