Question

我正在下载生成的ics日历，在下载ics日历时，它正在下载名称，如＆＃34; ics＆＃34;。我想添加像＆＃34; test.ics＆＃34;这样的名字，但我无法添加名称。请帮我动态添加名称到下载的ics文件。使用下面的代码将ics文件转换为字节。

private byte[] calendarAsByteArray(net.fortuna.ical4j.model.Calendar calendar) throws FileNotFoundException {
    byte[] bytes;
    try {
        ByteArrayOutputStream output =  new ByteArrayOutputStream();
        CalendarOutputter outputter = new CalendarOutputter();
        outputter.setValidating(false);
        outputter.output(calendar, output);
        bytes = output.toByteArray();

    } catch (Exception e) {
        throw new IllegalStateException("can't convert calendar to bytes: "+e);
    }
    return bytes;
}

您可以将您的bytes数组写入文件并指定所需的文件名：

    private byte[] calendarAsByteArray(net.fortuna.ical4j.model.Calendar calendar) throws FileNotFoundException {
        byte[] bytes;
        try {
            ByteArrayOutputStream output =  new ByteArrayOutputStream();
            CalendarOutputter outputter = new CalendarOutputter();
            outputter.setValidating(false);
            outputter.output(calendar, output);
            bytes = output.toByteArray();

            FileOutputStream fos = new FileOutputStream("test.ics");
            fos.write(bytes);
            fos.close()

    } catch (Exception e) {
        throw new IllegalStateException("can't convert calendar to bytes: "+e);
    }
    return bytes;
}

如何将文件名添加到转换后的字节文件中
