请问我这websocket推送过来的是什么格式

Question

可以把转化成常规的数据格式吗
我使用console.log(JSON.parse(greeting.body).content);无法解析

    {"content":"{\"lineCode\":\"CX20190901170607\",\"lineName\":\"产线1\",\"workstationCode\":\"GW20190903132744\",\"workstationName\":\"压槽工位\",\"deviceCode\":\"SBXX20190828101942\",\"deviceName\":\"22\",\"status\":\"BREAKDOWN\",\"faultCode\":\"333\",\"costTime\":0,\"sumCostTime\":14842,\"count\":2,\"maintainStatus\":\"0\"}"}

Answer 1

let data = {"content":"{"lineCode":"CX20190901170607","lineName":"产线1","workstationCode":"GW20190903132744","workstationName":"压槽工位","deviceCode":"SBXX20190828101942","deviceName":"22","status":"BREAKDOWN","faultCode":"333","costTime":0,"sumCostTime":14842,"count":2,"maintainStatus":"0"}"}
let result = data.content
JSON.parse(result)

Answer 2

JSON.parse只能解析字符串
JSON.parse(greeting.body.content);

Answer 3

这是字符串格式(对象->字符串)啊，你需要JSON.parse(str)来将其转化为对象
