golang 获取当前路径和上一级父路径(目录)
package main import ( "fmt" "log" "os" "path/filepath" "strings" ) func substr(s string,pos,length int) string { runes := []rune(s) l := pos + length if l > len(runes) { l = len(runes) } return string(runes[pos:l]) } func getParentDirectory(dirctory string) string { return substr(dirctory,strings.LastIndex(dirctory,"/")) } func getCurrentDirectory() string { dir,err := filepath.Abs(filepath.Dir(os.Args[0])) if err != nil { log.Fatal(err) } return strings.Replace(dir,"\\","/",-1) } func main() { var str1,str2 string str1 = getCurrentDirectory() str2 = getParentDirectory(str1) fmt.Println(str2) }原文链接:https://www.f2er.com/go/191028.html
