如何使用alamofire swift解析此json

Question

我只想从此JSON响应中解析userID <- hash key total_connected <- Integer (Integer incremented on a connection from the same user id) status <- "online"/"offline" (If the total_connected is 0 then offline otherwise online) 怎么办

 secure = true
 transports = WebSocket
 reconnection = true
 forceNew = true

我正在使用alamofire

Answer 1

Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)
            .responseJSON { response in
                print(response) //to get status code
                if let status = response.response?.statusCode {
                    switch(status){
                    case 201:
                        print("example success")
                    default:
                        print("error with response status: \(status)")
                    }
                } //to get JSON return value
            if let result = response.result.value {
                let JSON = result as! NSDictionary
                print(JSON)
            }

        }

您可以使用此 JSON 生成器：Link

import Foundation

struct RootClass: Codable {

    let message: String
    let result: Result
    let status: Bool

    private enum CodingKeys: String, CodingKey {
           case message = "message"
        case result = "result"
        case status = "status"
    }

    init(from decoder: Decoder) throws {
        let values = try decoder.container(keyedBy: CodingKeys.self)
        message = try values.decode(String.self, forKey: .message)
        result = try values.decode(Result.self, forKey: .result)
        status = try values.decode(Bool.self, forKey: .status)
    }

}


struct Result: Codable {

    let address: String
    let cityName: String
    let countryName: String
    let createdAt: String
    let deviceType: Int
    let firstName: String
    let gender: Int
    let id: Int
    let isActive: Int
    let lastName: String
    let otp: Int
    let pincode: String
    let stateName: String
    let swithAddWithoutHub: Int
    let updatedAt: String
    let userEmail: String
    let userMobile: Int
    let userName: String
    let userPassword: String
    let verified: Int

    private enum CodingKeys: String, CodingKey {
        case address = "address"
        case cityName = "city_name"
        case countryName = "country_name"
        case createdAt = "created_at"
        case deviceType = "device_type"
        case firstName = "first_name"
        case gender = "gender"
        case id = "id"
        case isActive = "is_active"
        case lastName = "last_name"
        case otp = "otp"
        case pincode = "pincode"
        case stateName = "state_name"
        case swithAddWithoutHub = "swith_add_without_hub"
        case updatedAt = "updated_at"
        case userEmail = "user_email"
        case userMobile = "user_mobile"
        case userName = "user_name"
        case userPassword = "user_password"
        case verified = "verified"
    }    

    init(from decoder: Decoder) throws {
        let values = try decoder.container(keyedBy: CodingKeys.self)
        address = try values.decode(String.self, forKey: .address)
        cityName = try values.decode(String.self, forKey: .cityName)
        countryName = try values.decode(String.self, forKey: .countryName)
        createdAt = try values.decode(String.self, forKey: .createdAt)
        deviceType = try values.decode(Int.self, forKey: .deviceType)
        firstName = try values.decode(String.self, forKey: .firstName)
        gender = try values.decode(Int.self, forKey: .gender)
        id = try values.decode(Int.self, forKey: .id)
        isActive = try values.decode(Int.self, forKey: .isActive)
        lastName = try values.decode(String.self, forKey: .lastName)
        otp = try values.decode(Int.self, forKey: .otp)
        pincode = try values.decode(String.self, forKey: .pincode)
        stateName = try values.decode(String.self, forKey: .stateName)
        swithAddWithoutHub = try values.decode(Int.self, forKey: .swithAddWithoutHub)
        updatedAt = try values.decode(String.self, forKey: .updatedAt)
        userEmail = try values.decode(String.self, forKey: .userEmail)
        userMobile = try values.decode(Int.self, forKey: .userMobile)
        userName = try values.decode(String.self, forKey: .userName)
        userPassword = try values.decode(String.self, forKey: .userPassword)
        verified = try values.decode(Int.self, forKey: .verified)
    }
}

然后用alamofire解析

Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)
        .responseJSON { response in
            print(response) //to get status code
            if let status = response.response?.statusCode {
                switch(status){
                case 201:
                    print("example success")
                default:
                    print("error with response status: \(status)")
                }
            } //to get JSON return value
        if let result = response.result.value {
            let JSON = result as! RootClass
            print(JSON)
        }

    }

Answer 3

我的建议是使用SwiftyJSON： SwiftyJSON

看这个例子：

Alamofire.request(url, method: .get).validate().responseJSON { response in
    switch response.result {
    case .success(let value):
        let json = JSON(value)
        print("JSON: \(json)")
    case .failure(let error):
        print(error)
    }
}

之后，您可以说类似这样的话

json["id"]
