How to find whether a file exists in golang

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)
}

Copy after login

os.Stat(): can be used to obtain file information.

IsExist(): Determine whether the file or directory exists based on the error.
