问题描述
输入JSON在下面 [ { “ correlationId”：“ 12345”， “ payloadFormat”：“金钱”， “有效载荷”：{ “ DE61”：“ 000001000150084063368”， “ location”：“ south”， “ name”：“ Dallas”， “ pop”：“ 2M” } }， { “ correlationId”：“ ed1e3”， “ payloadFormat”：“现金”， “有效载荷”：{ “ DE”：“ 000001000150084063368”， “ location”：“ west”， “ name”：“ LosAngeles”， “ pop”：“ 4M” } } ]
需要按照以下输出消息进行转换。
[ {
"payload": {
"correlationId": "12345","payloadFormat": "Money","DE61SF1": "00","DE61SF2": "100015008","DE61SF3": "4063368","location": "south","name": "Dallas","pop": "2M"
}
}， {
"payload": {
"correlationId": "ed1e3","payloadFormat": "Cash","location": "west","name": "LosAngeles","pop": "4M"
}
} ]

// Here it is moved as TMPDE
