Programmatically turn off logging revel framework
问题
你好！以下是翻译好的内容：
如何以编程方式关闭如下所示的日志记录。我需要这样做以便能够在运行测试套件时不会填充测试日志中的警告和信息日志。
revel.INFO.printf("")
谢谢你的帮助。

从revel包中，你有：
var (
// Loggers
TRACE = log.New(ioutil.Discard, "TRACE ", log.Ldate|log.Ltime|log.Lshortfile)
INFO = log.New(ioutil.Discard, "INFO ", log.Ldate|log.Ltime|log.Lshortfile)
WARN = log.New(ioutil.Discard, "WARN ", log.Ldate|log.Ltime|log.Lshortfile)
ERROR = log.New(&error_log, "ERROR ", log.Ldate|log.Ltime|log.Lshortfile)
)
从log包中，你有：
func New
func New(out io.Writer, prefix string, flag int) *Logger
New函数创建一个新的Logger。out变量设置日志数据将被写入的目标。prefix出现在每个生成的日志行的开头。flag参数定义了日志的属性。
从ioutil包中，你有：
var Discard io.Writer = devNull(0)
Discard是一个io.Writer，所有的写入调用都成功而不做任何操作。
因此，要关闭revel.INFO日志，请尝试：
revel.INFO = log.New(ioutil.Discard, "INFO ", log.Ldate|log.Ltime|log.Lshortfile)
英文:
From package revel you have:
> var (
> // Loggers
> TRACE = log.New(ioutil.Discard, "TRACE ", log.Ldate|log.Ltime|log.Lshortfile)
> INFO = log.New(ioutil.Discard, "INFO ", log.Ldate|log.Ltime|log.Lshortfile)
> WARN = log.New(ioutil.Discard, "WARN ", log.Ldate|log.Ltime|log.Lshortfile)
> ERROR = log.New(&error_log, "ERROR ", log.Ldate|log.Ltime|log.Lshortfile)
> )
From package log you have:
> func New
>
> func New(out io.Writer, prefix string, flag int) *Logger
>
> New creates a new Logger. The out variable sets the destination to

From package ioutil you have:
> var Discard io.Writer = devNull(0)
>
> Discard is an io.Writer on which all Write calls succeed without doing
> anything.
Therefore, to turn off the revel.INFO log try:
revel.INFO = log.New(ioutil.Discard, "INFO ", log.Ldate|log.Ltime|log.Lshortfile)
