我正在从API中获取JSON数据，并且成功获得了响应，但是对我来说，有一个问题，即如何在没有密钥的情况下获得直接价值，让我向您展示我的响应

这是我的回复，现在我将向您展示我正在成功获取message_list数组的数据，但问题是如何获取电话号码（即您在我的回复中显示的主要数组），我希望数字列表是数组在辅助消息列表数组中
func messageListAPI(){
let preferences = UserDefaults.standard
let uid = "u_id"
let acTkn = "acc_tkn"
let u_ID = preferences.object(forKey: uid)
let A_Token = preferences.object(forKey: acTkn)
let params = ["user_id": u_ID!,"access_token": A_Token!,"twilio_number": "+13344313181"]
// print(params)
Alamofire.request(messagelist, method: .post, parameters: params).responseJSON(completionHandler: {(response) in
switch response.result{
case.success(let value):
let json = JSON(value)
print(json)
let message = json["message"].stringValue
let success = json["success"].stringValue
let data = json["message_list"]
let model = ResponseModel(message: message, success: success, messageList: data) // Here i am getting error
case.failure(let error):
print(error.localizedDescription)
}
})
}
这是我成功获得message_list的API调用方法，谁能帮助我获取数字列表

您应创建以下模型以进行响应：
/// Main response model
struct ResponseModel: Codable {
let message: String
let success: String
let messageList: [[String: [MessageList]]]
enum CodingKeys: String, CodingKey {
case message, success
case messageList = "message_list"
}
}
/// MessageList Model
struct MessageList: Codable {
let body: String
let from: String
let sid: String
let status: Status
let dateSent: String
let dateCreated
let dateUpdated
let to: String
enum CodingKeys: String, CodingKey {
case body, from, sid, status
case dateSent = "date_sent"
case dateCreated = "date_created"
case dateUpdated = "date_updated"
case to
}
}
/// For status field
enum Status: String, Codable {
case delivered = "delivered"
case received = "received"
case sent = "sent"
}
您可以将这些模型与 Alamofire
一起使用/// YOU MUST CHANGE 'ResponseType' with the real type of response
func messageListAPI(_ completion: @escaping (ResponseType) -> Void) {
let urlString = "http://yourUrl"
Alamofire.request(urlString).response { response in
guard let data = response.data else { return }
do {
let decoder = JSONDecoder()
let response: ResponseType = try decoder.decode(ResponseModel.self, from: data)
let numberList = response.messageList.compactMap({ $0.keys })
print("my numberList -> \(numberList)")
completion(response)
} catch let error {
print(error)
completion(nil)
}
}
}
用法：
messageListAPI { response in
/// If response is nil it's means error appear.
/// Otherwise it is successful
print(response)
}
您还可以使用 URLSession
guard let yourUrl = URL(string: "https://myUrl") else { return }
URLSession.shared.dataTask(with: yourUrl) { (data, response , error) in
guard let data = data else { return }
do {
let decoder = JSONDecoder()
let data = try decoder.decode(ResponseModel.self, from: data)
print(data)
} catch let error {
print("Err", error)
}
}.resume()
您可以使用这些模型来解析响应JSON。然后，您将获得这样的号码列表：
let numberList = ResponseModel.messageList.compactMap({ $0.keys })
如果对将Codable模型用于API响应有任何疑问，请立即询问。
享受。

只需粘贴您的json响应，即可从https://app.quicktype.io/
获得模型URLSession.shared.dataTask(with: yourURL) { (data, resonse, err) in
if err == nil{
}else{
do{
let model = JSONDecoder().decode(YourModel.self, from: data!)
}catch(let decodeErr){
print(decodeErr)
}
}
}.resume()

由于消息列表是一个数组，因此您可以尝试执行此操作-
let data = json["message_list"]
for (index, item) in data.enumerated() {
print(item[index])
}
