我有以下代码,因为我使用了 gin 框架和 filewalk,所以无法在游戏中运行。
package main
import (
"fmt"
"os"
"path/filepath"
"time"
"regexp"
"github.com/gin-gonic/gin"
"sort"
"strings"
"github.com/davidscholberg/go-durationfmt"
)
var filext = regexp.MustCompile(`\.[mM][pP]4|\.[mM]4[vV]|\.jpg|\.[hH]264|\.go`)
var m map[int]string
var keys []int
func main() {
if gin.IsDebugging() {
fmt.Print("This progamm shows only the path and the age of a file in 'STARTDIR'\n")
fmt.Print("only the following files will be handled '.[mM][pP]4|.[mM]4[vV$|.[hH]264|.go'\n")
fmt.Print("The git repository: https://gitlab.com/aleks001/show-files-age \n")
}
if len(os.Getenv("LISTEN_IP_PORT")) == 0 {
fmt.Print("I need a ip and port on which I should listen.\n")
os.Exit(1)
}
router := gin.Default()
gin.DisableConsoleColor()
router.GET("/videoinfo",getInfo)
router.Run(os.Getenv("LISTEN_IP_PORT"))
}
func getInfo(c *gin.Context) {
loc, _ := time.LoadLocation("Europe/Vienna")
var startdir = ""
if os.Getenv("STARTDIR") != "" {
startdir = os.Getenv("STARTDIR")
} else if c.GetHeader("STARTDIR") != "" {
startdir = c.GetHeader("STARTDIR")
} else {
c.String(404,"Startdir not found <br>\n")
return
}
m = make(map[int]string)
keys = nil
filepath.Walk(startdir,walkpath)
for k := range m {
keys = append(keys, k)
}
sort.Ints(keys)
for _, k := range keys {
t := time.Date(time.Now().Year(),time.Now().Month(),time.Now().Day(),time.Now().Hour(),k,time.Now().Second(),time.Now().Nanosecond(),loc)
durStr, err := durationfmt.Format(time.Since(t), "%h:%m")
if err != nil {
fmt.Println(err)
} else {
//fmt.Println(durStr)
fmt.Printf("Key: %s Value: %s\n", durStr , m[k])
c.String(200,"Minutes: %s File: %s\n", durStr, m[k])
}
}
}
func walkpath(path string, f os.FileInfo, err error) error {
if err != nil {
fmt.Println(err)
} else {
if filext.MatchString(path) {
age := time.Now().Sub(f.ModTime())
path_new := strings.Replace(path,"/videos/","",1)
// path_new := strings.Replace(path,"..\\","",1)
/*
fmt.Printf("Path: %s, ModTime: %s, Age: %s <br>\n", walker.Path(), walker.Stat().ModTime(), age)
c.String(200,"Path: %s, ModTime: %s, Age: %s <br>\n", walker.Path(), walker.Stat().ModTime(), age)
*/
fmt.Printf("Path: %s, Age: %d age minutes %0.2f <br>\n", path_new, age, age.Minutes())
m[int(age.Minutes())]=path_new
//c.String(200,"Path: %s, Age: %0.2f <br>\n", path, age.Minutes())
}
//fmt.Printf("%s with %d bytes at motime %s\n", path,f.Size(), f.ModTime())
}
return nil
}
我想要做的是基于 filext
als 过滤器和 modtime 作为排序标准的文件排序输出。
我能够满足大部分请求,但输出看起来很难看,如下所示。
我使用 https://github.com/davidscholberg/go-durationfmt 来格式化持续时间,但输出看起来很难看,或者我想念图书馆。
Minutes: 0:6 File: upload/dir003/file1.m4v
Minutes: 0:5 File: transfer/dir5/file2.jpg
Minutes: -5:-48 File: transfer/dir001/file.mp4
Minutes: -6:-21 File: transfer/03.jpg
Minutes: -6:-22 File: transfer/02.mp4

例如,要为持续时间提供自定义格式,
游乐场:https: //play.golang.org/p/HT4bFfoA5r
输出:
如果您想按持续时间排序,请使用 Go
sort
包。我将对ModTime
进行排序以推迟持续时间的计算,Since(ModTime)
,以便在打印时准确无误。例如,游乐场:https: //play.golang.org/p/j2TUmJdAi4
