美好的一天!我想下载自动生成的文件qwerty.csv,但它只返回文本"12345"(没有文件).你能帮助我吗？

UI

<script type="text/javascript">
function getCsv() {
    var ids = getSelectedRecordIds();
    $.post('/payments/form_csv.csv', { ids: ids }, function(data) {});
}
</script>

调节器

def form_csv
    csv_string = CSV.generate do |csv|
        csv << ["12345"]
    end

    respond_to do |format|
        format.csv {
            send_data csv_string, :type => 'text/csv; charset=utf-8; header=present', :disposition => "attachment; filename=qwerty.csv", :filename => "qwerty.csv"
        }
    end
end

在控制台中
