对象中的数组如何转成字符串后在重新拼接？？

Question

原数据

{
    "app_name": "测试1231",
    "app_id": "3123123",
    "secret": "31213123",
    "app_role": 2,
    "scope": [
        "report_service",
        "account_service"
    ]
}

期望：

{
   "app_name": "测试1231",
    "app_id": "3123123",
    "secret": "31213123",
    "app_role": 2,
    "scope": 'report_service,account_service'
}

Answer 1

const json = {
    "app_name": "测试1231",
    "app_id": "3123123",
    "secret": "31213123",
    "app_role": 2,
    "scope": [
        "report_service",
        "account_service"
    ]
};

json.scope = json.scope.join(',');
console.log( json );

Answer 2

let obj = {
    "app_name": "测试1231",
    "app_id": "3123123",
    "secret": "31213123",
    "app_role": 2,
    "scope": [
        "report_service",
        "account_service"
    ]
}

for (let key of obj) {
    if(Array.isArray(obj[key])){
        obj[key] = obj[key].join(',')
    }
}
