}

好的，这是我从服务器收到的 json 格式

现在我想将它解码到我的结构中，但仍然没有运气。

struct ChildrenTable: Decodable {
    var values: [[String]]?
}

我在 URLSession 上的调用者方法看起来像这样

URLSession.shared.dataTask(with: request) { (data, response, err) in
        guard let data = data else { return }

        let dataAsString = String(data: data, encoding: .utf8)
        print(dataAsString)

        do {
            let children  = try
                JSONDecoder().decode(ChildrenTable.self, from: data)
                print (children)
        } catch let jsonErr {
            print ("Error serializing json: ", jsonErr)
        }
    }.resume()

我得到的错误是

Error serializing json:
