在下文中一共展示了ParseGroupFilter函数的2个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于系统推荐出更棒的Golang代码示例。
示例1: lookupGidByName
func lookupGidByName(nameOrGid string) (int, error) {
groups, err := user.ParseGroupFilter(func(g *user.Group) bool {
return g.Name == nameOrGid || strconv.Itoa(g.Gid) == nameOrGid
})
if err != nil {
return -1, err
}
if groups != nil && len(groups) > 0 {
return groups[0].Gid, nil
}
return -1, fmt.Errorf("Group %s not found", nameOrGid)
}示例2: ListenAndServe
// ListenAndServe sets up the required http.Server and gets it listening for
// each addr passed in and does protocol specific checking.
func ListenAndServe(proto, addr string, eng *engine.Engine, logging, enableCors bool, dockerVersion string) error {
r, err := createRouter(eng, logging, enableCors, dockerVersion)
if err != nil {
return err
}
if proto == "fd" {
return ServeFd(addr, r)
}
if proto == "unix" {
if err := syscall.Unlink(addr); err != nil && !os.IsNotExist(err) {
return err
}
}
l, err := listenbuffer.NewListenBuffer(proto, addr, activationLock, 15*time.Minute)
if err != nil {
return err
}
// Basic error and sanity checking
switch proto {
case "tcp":
if !strings.HasPrefix(addr, "127.0.0.1") {
log.Println("/!\\ DON'T BIND ON ANOTHER IP ADDRESS THAN 127.0.0.1 IF YOU DON'T KNOW WHAT YOU'RE DOING /!\\")
}
case "unix":
if err := os.Chmod(addr, 0660); err != nil {
return err
}
groups, err := user.ParseGroupFilter(func(g *user.Group) bool {
return g.Name == "docker"
})
if err != nil {
return err
}
if len(groups) > 0 {
utils.Debugf("docker group found. gid: %d", groups[0].Gid)
if err := os.Chown(addr, 0, groups[0].Gid); err != nil {
return err
}
}
default:
return fmt.Errorf("Invalid protocol format.")
}
httpSrv := http.Server{Addr: addr, Handler: r}
return httpSrv.Serve(l)
}
