使用脚本计算 WSO2 6.1.1 中传递日期的下一个日期

Question

我正在尝试将日期的第二天设为已通过的日期。

正在从注册表文件中读取日期。

使用冒号分隔符拆分以上内容，并将其视为开始日期和结束日期。使用脚本调解器为两个日期添加日期的第二天。因为处理完成后，我需要使用下一天日期更新注册表。（此处尚未包含，仅包含日期转换）

预期输出：

下一个开始日期：2020-12-02 下一个结束日期：2021-01-01

您不需要调用 new Date()，因为您已经有了日期字符串并且您使用的日期对象是 javascript 对象。试用这段代码。日期在此处硬编码

<script language="js"><![CDATA[var log = mc.getServiceLog(); 
            log.info("Logging inside Script Mediator"); 

            var startDate = '2020-12-01';
            var endDate = '2020-12-31';   
            var nextStartDate=addNextDay(startDate);
            mc.setProperty("nextStartDate", nextStartDate);
            var nextEndDate=addNextDay(endDate);
             mc.setProperty("nextEndDate", nextEndDate);
            log.info("startDate:  " + startDate);
            log.info("endDate:  " + endDate);
            function addNextDay(dateString) {
            var  simpleDateFormat = Packages.java.text.SimpleDateFormat;
            var fomatter = new simpleDateFormat("yyyy-MM-dd");
            var currentDate = dateString;
            
            var calendar = Packages.java.util.Calendar.getInstance();
            calendar.setTime(fomatter.parse(currentDate));
            var daysToAdd = mc.getProperty("days");
            calendar.add(Packages.java.util.Calendar.DATE, 1);
            var destDate = fomatter.format(calendar.getTime()); 
            log.info("Destination date : " + destDate );
            return destDate;
            }]]></script>
