一个QlikSense脚本，用于通过Rest API以JSON格式从JIRA加载带有问题和工作日志的数据

Question

QlikSense中有两个连接API，分别称为URL1（问题数据）和URL2（工作日志）。从URL1获取工作日志记录是有限制的，只有20条记录，分页没有分发，因此您必须从URL2加载工作日志。

如何执行以下操作：

从URL1加载数据时，脚本将分析[worklog]部分中“ total”字段的值，如果该值大于20，则来自字段[__KEY_fields]的键将采用相应的值[worklogs]部分中的[self_u4]字段并将其作为URL2传递给它，以加载数据。然后，该控件将从URL1返回到“ total“> 20之后的下一条记录，继续加载并分析数据。
