如何在GAE Go运行时中记录消息？

Question

I am using the following simple code snippet to log messages in my application and during local testing I see all my logs.

However, I do not see any application logs when I deploy the app to GAE. Do I need to set logging properties anywhere? Or am I using the wrong logging library?

import (
    "log"
)

func Info(logMessage string, v ...interface{}) {
    if v != nil {
        log.Printf("[INFO]  "+logMessage, v)
    } else {
        log.Printf("[INFO]  " + logMessage)
    }
}

You should be using the app engine logging provided with the Context interface.
It provides several Debugf, Infof, Warningf, Errorf, and Criticalf.
