Golang determines whether the file exists:
// 判断所给路径文件/文件夹是否存在
func Exists(path string) bool {
_, err := os.Stat(path) //os.Stat获取文件信息
if err != nil {
if os.IsExist(err) {
return true
}
return false
}
return true
}
// 判断所给路径是否为文件夹
func IsDir(path string) bool {
s, err := os.Stat(path)
if err != nil {
return false
}
return s.IsDir()
}
// 判断所给路径是否为文件
func IsFile(path string) bool {
return !IsDir(path)
}os.Stat(): can be used to obtain file information.
IsExist(): Determine whether the file or directory exists based on the error.
