使用Codable解析json数据

Question

我刚开始使用Codable来解析来自JSON的数据，并且我的JSON格式遇到了问题。我无法将正确的字段解析为我的Employee对象。这是我第一次使用codable来处理一个复杂的URL。下面是我的JSON url的结构：https://ibb.co/WgDNMNT

{
  "students": [
    {
      "uuid": "0djkdjjf734783749c",
      "full_name": "Joe Morris",
      "phone_number": "44445399",
      "email_address": "jm99@jfgj.com",
      "biography": "student of arts"
    },
    {
      "uuid": "0djkdjjf734783749c",
      "full_name": "Joe Morris",
      "phone_number": "44445399",
      "email_address": "jm99@jfgj.com",
      "biography": "student of arts"
    }
  ]
}

下面是我的代码：

struct Students: Codable {
    var uuid: String?
    var fullName: String?
    var phoneNumber: String?
    var emailAddress: String?
    var biography: String?

}
//Custom Keys
enum CodingKeys: String, CodingKey{
    case uuid
    case fullname = "full_name"
    case phoneNumber = "phone_number"
    case emailAddress = "email_address"
    case biography = "biography"
}


func parseData(){
    guard let url = URL(string: "xxxxxxxxxx") else {return}
    let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
        guard let dataResponse = data,
            error == nil else {
                print(error?.localizedDescription ?? "Error")
                return }
        do{
            let decoder = JSONDecoder()
            let model = try decoder.decode([Students].self, from: dataResponse)

        } catch let parsingError {
            print("Error", parsingError)
        }
    }
    task.resume()
}

替换

let model = try decoder.decode([Students].self, from: dataResponse)

使用

let model = try decoder.decode([String:[Students]].self, from: dataResponse)
print(model["students"])
