go实现按行读取文件内容

func ReadLineFile(fileName string) ([]string,error) {
    var lines []string
    file, err := os.Open(fileName)
    if err != nil {
        return nil,errors.New("Read Line File: Open file error " + err.Error())
    }
    //scan line
    scanner := bufio.NewScanner(file)
    for scanner.Scan() {
        lines=append(lines,scanner.Text()
    }
    return lines,nil
}

func main() {
    service.ReadLineFile("attachment/css/montserrat.css")
}
