我有这样的 JSON 响应:
我目前将我的可解码结构设计如下:
struct PortfolioResponseModel: Decodable {
var dataset: Dataset
struct Dataset: Decodable {
var data: Array<PortfolioData> //I cannot use [Any] here...
struct PortfolioData: Decodable {
//how to extract this data ?
}
}
}
问题是,我如何提取数组中的数据,它的值可以是 Double 或 String。
这是在操场上进行这项工作的示例字符串:
let myJSONArray =
"""
{
"dataset": {
"data": [
[
"2018-01-19",
181.29
],
[
"2018-01-18",
179.8
],
[
"2018-01-17",
177.6
],
[
"2018-01-16",
178.39
]
]
}
}
"""
提取数据:
do {
let details2: PortfolioResponseModel = try JSONDecoder().decode(PortfolioResponseModel.self, from: myJSONArray.data(using: .utf8)!)
//print(details2)
//print(details2.dataset.data[0]) //somehow get "2018-01-19"
} catch {
print(error)
}
