可以新增一个function节点,然后这个节点的msg.payload为Call service需要的变量信息。如你提到的data,一般可以点近call service这个节点,里面有“load example data”,这样你就可以看需要传入哪些变量了。
如load example data的示意数据如下:
{"summary":"Department Party","description":"Meeting to provide technical review for 'Phoenix' design.","start_date_time":"2022-03-22 20:00:00","end_date_time":"2022-03-22 22:00:00","start_date":"2022-03-22","end_date":"2022-03-23","in":"{"days": 2} or {"weeks": 2}"}
