Go 普通LOG输出

因为Go 语言中没有自带的宏, 来表示行号和文件, 需要从方法中去获取,麻烦.所以封装了一个函数,用于输出平时程序的打印日志

package main
import (
    "fmt"
    "runtime"
    "strconv"
)
func AddLog(msg string) string {
    _, _, line, ok := runtime.Caller(1)
    s := ""
    if ok {
        s = " [" + strconv.Itoa(line) + "]"   
        msg = "Log : " + msg  + s     
        return msg
    }
    return ""
}
  // **第一种输出格式**, 只有行号和自定义错误信息
  //输出格式[Log] : dial Ok [47]


func AddLog(msg string) string {
    _, _, line, ok := runtime.Caller(1)
    s := ""
    if ok {
        t := time.Now()
        s = " " + t.String() + " " + file + ":" + strconv.Itoa(line)
         msg = "Log : " + msg  + s 
        //logBuffer.Log = append(logBuffer.Log, msg)
        return msg
    }
    return ""
}
      // **第二种输出格式**, 包含当前LOG日志的日期,行号,文件,自定义错误信息
       //输出格式为: [Log] : dial Ok 2017-03-17 13:45:38.4388648 +0800 CST F:/Go/src/socket_test_dial.go:45
