如何快速在模型中存储 JSON 响应 [英] How to store JSON response in Model in swift

问题描述

我已经为 loginviewcontroller 响应创建了模型

I have created model for loginviewcontroller response

我收到如下响应，如何在 loginviewcontroller 中向此模式添加值.. 我收到此响应的位置

I am getting response like below, how to add values to this mode in loginviewcontroller.. where i am getting this response

struct Employees: Codable {
let jsonrpc: String
let result: Result
  }

 // MARK: - Result
 struct Result: Codable {
let userdata: Userdata
let token: String
}

// MARK: - Userdata
struct Userdata: Codable {
let id: Int
let fname, lname, email: String
.......
}

loginviewcontroller APICall:

loginviewcontroller APICall:

 func loginService(){

let url = URL(string: "https://apkool.com")!
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")

let jsonpost = LoginData(jsonrpc: "2.0", params: (PostLogin(email: nameTf.text!, password: passwordTf.text!, device_id: "2")))
    
do {
    let jsonBody = try JSONEncoder().encode(jsonpost)
    request.httpBody = jsonBody
} catch {
    print("Error while encoding parameter: \(error)")
}
    let session = URLSession.shared
let task = session.dataTask(with: request) { [self] (data, response, error) in
        
        guard let data = data else {return}
        
    do{
        let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String:Any]
        print("the json output \(String(describing: json))")
        
        let error = json!["error"] as? [String : Any]
        
        let status = error?["status"] as? [String : Any]
                        
        DispatchQueue.main.sync{
        if error != nil{
            let controller = UIAlertController(title: "Alert", message: "Your email is not verified", preferredStyle: .alert)
            let ok = UIAlertAction(title: "OK", style: .default, handler: nil)
            let cancel = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)

            controller.addAction(ok)
            controller.addAction(cancel)

            self.present(controller, animated: true, completion: nil)
        }
            
            
        else{
            
            let res = json?["result"] as? [String : Any]

            let uData = res?["userdata"] as? [String : Any]
            var nameLogin = uData?["slug"] as? String
            var emailLogin = uData?["email"] as? String
            print("login name \(String(describing: nameLogin))")
            
            let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "ProfileViewController1") as? ProfileViewController1
            vc?.name = nameLogin
            vc?.email = emailLogin
            self.navigationController?.pushViewController(vc!, animated: true)
            
        }
        }
        print("the error is \(error)")
    }catch{ print("Error while decoding: \(error.localizedDescription)") }
    }
    task.resume()

  }

我想向模型添加登录响应，以便在另一个视图控制器中使用这些值..请帮忙..我被困在这里很久了

i want to add login response to model to use these values in another viewcontroller.. pls do help.. i got stuck here from long time

对于上述 api，我收到登录响应:

for above api i am getting response for login:

  {
"jsonrpc": "2.0",
"result": {
    "userdata": {
        "id": 47,
        "fname": "sample",
        "lname": "test",
        "last_login": "2021-02-23 15:04:56",
        "created_at": "2021-02-17 20:22:49",
        "updated_at": "2021-02-23 15:04:56",
        "deleted_at": null
    },
    "devicetoken": fasfcsdfdsfsdfsd
}
}

推荐答案

因为您可能会从服务器收到这样的错误:

Since you may get an error from the server like so:

{
   "jsonrpc": "2.0",
   "error": {
       "status": {
           "code": "-32706",
           "message": "Not Verified",
           "meaning": "Your email is not verified."
      }
   }
}

改变你的模型:

struct Employees: Codable {
    let jsonrpc:String
    let result:Result?
    let error:ResponseError?
}

struct ResponseError:Codable {
    let status:ErrorStatus
}

struct ErrorStatus:Codable {
    let code:String?
    let message:String?
    let meaning:String?
}

// MARK: - Result
struct Result: Codable {
    let userdata: Userdata
    let token: String
}
  
// MARK: - Userdata
struct Userdata: Codable {
let id: Int
let fname, lname, slug, email: String
......

//IMPORTANT: MAKE SURE YOUR CONSTANT NAMES ARE EXACTLY THE SAME AS YOUR 
            //RESPONSE, OTHERWISE YOU MUST ADD AN ENUM like so: 

private enum CodingKeys: String, CodingKey {
        case firstName = "fname"
}

然后在你的 api

func loginService(){
        
        let url = URL(string: "https://appleskool.com/preview/appleskool_code/api/login")!
        var request = URLRequest(url: url)
        request.httpMethod = "POST"
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        
        let jsonpost = LoginData(jsonrpc: "2.0", params: (PostLogin(email: nameTf.text!, password: passwordTf.text!, device_id: "2")))
        
    let session = URLSession.shared
    let task = session.dataTask(with: request) { [self] (data, response, error) in
        guard let data = data else {return}
        let decoder = JSONDecoder()
        guard let employees = try? decoder.decode(Employees.self, from: data) else { return }
        //then you can access your result
        if let error = employees.error {
            //use your error
            print(error.status.message)
            print(error.status.meaning)
        }else{
            //use your data
            guard let user = employees.result else {return }
            print(user.userdata.fname)
            print(user.userdata.lname)
            print(user.userdata.email)
            print(user.userdata.slug)
            // or your can do what you already doing in your code 
            let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "ProfileViewController1") as? ProfileViewController1
            vc?.name = ser.userdata.fname
            vc?.lastName = ser.userdata.lname
            //if you want to pass the token
            vc?.token = user.token
            self.navigationController?.pushViewController(vc!, animated: true)
            // etc
        }
    }
    task.resume()
}
