Uncaught (in promise) SyntaxError: "[object Object]" is not valid JSON

A、数据格式为:
'{"switch": "true","version": "RSTP","age": "20","delay": "15","count": "6","hops": "20","mstName": "name","matRevision": "1"}'
B、json.parse() 操作后的数据为:
{ switch: 'true', version: 'RSTP', age: '20', delay: '15', count: '6', hops: "20", mstName: "name", matRevision: "1"}
C、数据展示为:
