```go
func GetMimeTypeFromFileExample() (string, error) {
	
    file, err := os.Open("./types.json")
        if err != nil {
            fmt.Println(err)
            return
        }
    defer func(file *os.File) {
        err := file.Close()
            if err != nil {
            fmt.Printf("error:%s", err)
        }
    }(file)
    return GetMimeTypeFromFile(file)
    // return "application/json"
}
