package main

import (
  "fmt"
  "log"
  "os"
)

func main(){
  logfile,err := os.OpenFile("d:/workspace/golang/test.log",os.O\_RDWR|os.O\_CREATE|os.O_APPEND,0);
  if err!=nil {
    fmt.Printf("%s\r\n",err.Error());
    os.Exit(-1);
  }
  defer logfile.Close();
  
  logger := log.New(logfile,"\r\n",log.Ldate|log.Ltime|log.Llongfile);
  logger.Println("hello");
  logger.Println("oh….");
  logger.Fatal("test");
  logger.Fatal("test2");
}

这里打开日志文件的时候,同时使用了””os.O_APPEND”这个,这样的话,日志会一直在文件最后面打印出来.
