使用go简单实现从IIS日志统计web的访问量

package main

import (

    "bufio"

    "fmt"

    "io"

    "os"

    "strings"

)

var UrlMap = make(map[string]int)

func main() {

    inputFile, err := os.Open("ex14060609.log")

    if err != nil {

        fmt.Println(err)

    }

    defer inputFile.Close()

    bufRD := bufio.NewReader(inputFile)

    for {

        str, err := bufRD.ReadString('\n')

        if err == io.EOF {

            break

        }

        //以"#"开头的要跳过,iiS 日志前几行是做了注释的

        if strings.HasPrefix(str, "#") {

            continue

        }

        //fmt.Printf("%s", str)

        //tmpArr 定义临时数组

        tmpArr := strings.Split(str, " ")

        //fmt.Println(tmpArr[5])

        //通过日志文件可知temArr[5]在web日志里是URL

        //str1 = tmpArr[5]

        //var temp UrlItem

        //sw变量的作用是一个开关，用它来判断tmpArr[5]是否已经在map里，如果不在，就新建一个map键值对

        sw := true

        for k, _ := range UrlMap {

            if k == tmpArr[5] {

                UrlMap[k]++

                sw = false

                break

            }

        }

        if sw {

            UrlMap[tmpArr[5]] = 1

        }

    }

    for k, v := range UrlMap {

        fmt.Printf("%s : %d\n", k, v)

    }

    //fmt.Printf("ddd")

    //UrlMap[tmpArr[5]] = 1

}
