程序分为站点端和中心端(相当于一个proxy).
这个小功能主要是解决,程序经常让我们去拖日志,特别烦.所以做个小程序.使程序可以自己去线上查看.
有个问题是,不能把游戏服务器暴露出来,还有就是不能占用业务机器的公网带宽.
这个小程序主要就是中心端(proxy)通过内网获取文件,然后转发给访问端.
中心端主要有两个文件,一个是程序文件.一个是我命名为json的文件(主要是根据ID来分辨分站)

分站程序：
目录结构我使用的是： --agent -|
---http.go
---sort.go
--maste.go
http.go内容：
package agent
import (
"errors"
"fmt"
"net/http"
"net/rpc"
"os"
)
var Http_path string
type Info_list int
func HttpServer(port,path string) {
Http_path = path
rpc.Register(new(Info_list))
rpc.HandleHTTP()
http.Handle("/",http.FileServer(http.Dir(path)))
err := http.ListenAndServe(fmt.Sprintf(port),nil)
fmt.Println(err)
}
func (i *Info_list) List(path string,result *Newlist) error {
path_l := Http_path + "/" + path
info,e := os.Stat(path_l)
if e != nil {
return e
}
if info.IsDir() {
L,_ := GetFilelist(path_l)
*result = L
return nil
} else {
return errors.New(path)
}
}
sort.go内容：
package agent import ( "io/IoUtil" "sort" "time" ) type Info struct { Name string Time time.Time } type Newlist []*Info func GetFilelist(path string) (Newlist,error) { l,err := IoUtil.ReadDir(path) if err != nil { return []*Info{},err } var list []*Info for _,v := range l { list = append(list,&Info{v.Name(),v.ModTime()}) } sort.Sort(Newlist(list)) return list,nil } func (I Newlist) Len() int { return len(I) } func (I Newlist) Less(i,j int) bool { return I[i].Time.Unix() < I[j].Time.Unix() } func (I Newlist) Swap(i,j int) { I[i],I[j] = I[j],I[i] }
maste.go内容：
package main
import (
"agent"
"flag"
)
func main() {
var port *string = flag.String("l",":1789","-l :1789 或者 -l 127.0.0.1:1789 默认是监听在1789的端口上")
var path *string = flag.String("p","./","-p ./ 或者 -p D:\\code")
flag.Parse()
go agent.HttpServer(*port,*path)
select {}
}
var configlist map[string]string var re *regexp.Regexp
