04_hw_signup_server

1. Create NetworkResult.swift

import Foundation

enum NetworkResult<T>{
    case success(T)
    case requestErr(T)
    case pathErr
    case serverErr
    case networkFail
}

2. Create ResponseString.swift

• 성공했을 때 response body 작성

import Foundation

struct ResponseString2: Codable {
    let success: Bool
    let message: String
    let data: Int
}

3. Create APIService

    static let shared = SignupService()

• singleton pattern : 모든 프로그램 생애 주기에서 딱 한 번 생성
• 모든 파일에서 전역으로 접근 가능

Alamofire.request(APIConstants.SignupURL, method: .post, parameters: body, encoding: JSONEncoding.default, headers: header)
            .responseData { response in // response 에 결과값 저장 -> print 해보기
                
                // parameter 위치
                switch response.result {
                    
                // 통신 성공 - 네트워크 연결
                case .success:
                    if let value = response.result.value {
                        
                        if let status = response.response?.statusCode {
                            switch status {
                            case 200:
                                do {
                                    let decoder = JSONDecoder()
                                    print("value", value)
                                    let result = try decoder.decode(ResponseString2.self, from: value)
                                    
                                    // ResponseString에 있는 success로 분기 처리
                                    switch result.success {

                                        print("success")
                                        completion(.success(result.data)) // NetworkResult 에서 접근
                                    case false:
                                        completion(.requestErr(result.message))
                                    }

                                    print(APIConstants.SignupURL)
                                }
                            case 400:
                                completion(.pathErr)
                            case 500:
                                completion(.serverErr)

            data in
            switch data {
                    
            case .success(let data):
                
                print(data)
                print ("success")
                break
            case .requestErr(_):
                print(".requestErr")
                break
            case .pathErr:
                print("pathErr")
                break
            case .serverErr:
                print("serverErr")
                break
            case .networkFail:
                print("networkErr")
                break
            }
        }
