golang 获取文件名称、后缀

• 通过文件路径，获取文件名称，后缀

func main(){
   var filePath="attachment/file/filename.txt"
   //获取文件名称带后缀
   fileNameWithSuffix:=path.Base(filePath)
   //获取文件的后缀(文件类型)
   fileType:=path.Ext(fileNameWithSuffix)
   //获取文件名称(不带后缀)
   fileNameOnly:=strings.TrimSuffix(fileNameWithSuffix, fileType)
  fmt.Printf("fileNameWithSuffix==%s\n fileType==%s;\n fileNameOnly==%s;",
             fileNameWithSuffix,fileType,fileNameOnly)
}

控制台打印:

fileNameWithSuffix==filename.txt
 fileType==.txt;
fileNameOnly=filename;
