使用swift中的字符串列表构造JSON有效内容

Question

我会为POST服务调用动态构造下面的有效负载。我不知道如何在字典中创建字符串列表

{
    "Id":"2025",
    "deviceType": "iphone",
    "category": ["Dental", "Vision"] 
}

我的代码

var categoryList = ["Dental", "Vision"]
let json = ["Id": "2025", "deviceType": "iphone", "category": categoryList] as! Dictionary<String, String>     
let jsonData = try? JSONSerialization.data(withJSONObject: json)

Answer 1

你可以这样做： -

并且无需将json转换为数据，您可以直接在SERVICE CAll中将此json发布为参数

let jsonToSend:[String:Any] = [
    "Id":"pass your id here",
    "deviceType":"device type here",
    "category":"category array here"
]
