我有几个对象:
{
"product":"bike",
"ExpectedDeliveryDate": "2018-11-05T00:00:00"
},
{
"product":"flowers",
"ExpectedDeliveryDate": "2018-11-05T00:00:00"
},
{
"product":"balls",
"ExpectedDeliveryDate": "2018-11-10T00:00:00"
},
{
"product":"phones",
"ExpectedDeliveryDate": "2018-11-10T00:00:00"
},
{
"product":"microphones",
"ExpectedDeliveryDate": "2018-11-08T00:00:00"
},
{
"product":"monitors",
"ExpectedDeliveryDate": "2018-11-08T00:00:00"
},
我想要一个不同日期的列表,删除重复的。如何在这里提取三个唯一日期
- 2018-11-05T00:00:00
- 2018-11-10T00:00:00
- 2018-11-08T00:00:00
使用工作流表达式?
