winston.info('Hello again distributed logs', { app: 'test', sid: 1 })
pino.info('Hello again distributed logs', { app: 'test', sid: 1 })

输出：

{"app":"test","sid":1,"level":"info","message":"Hello again distributed logs","timestamp":"2017-02-16T03:34:06.186Z"}
{"pid":4269,"hostname":"Macchiato.local","level":30,"time":1487216046197,"msg":"Hello again distributed logs {\"app\":\"test\",\"sid\":1}","v":1}

我有fluentd守护进程来拾取容器stdout并将其发送到cloudwatch。
在上面的示例中，cloudwatchlogs可以正确地从pino中检测元数据，我将能够像这样查询日志

{$.app = "test"}

然而，温斯顿控制台不是这样工作的，一切都推到log属性。
有谁知道怎么解决这个问题。我使用winston控制台和json: true和stringify: true
