我一直在尝试使用不同的函数,如sub & join将参数资源的默认值连接到变量(其他输入参数)。加入资源参数字符串与变量 - CFN
一个例子是:
"RuleQuery": {
"Description" : "rule query",
"Type" : "String",
"Default" : "SELECT parse_time(\"yyyy.MM.dd G 'at' HH:mm:ss
z\", timestamp(), \"Australia/Sydney\") AS
timestamp, * FROM {\"Ref\": \"TopicFilter\"}
WHERE CustomerId={\"Ref\": \"CustomerID\"}"
},
"TopicFilter": {
"Description" : "topic filter",
"Type" : "String",
"Default" : "001"
},
"CustomerID": {
"Description" : "condition",
"Type" : "String",
"Default" : "0001"
},
每次我得到一个错误,默认值应保持一个字符串。想知道是否有可能实现这一点?
谢谢
