  • 열거형(enum)에서는 저장 프로퍼티를 사용할 수 없다.
  static let user = UserDefaultService.shared.getUser()
  var baseURL: URL {
    return URL(string: "https://www.apple.com/")!
  }

위에 처럼 계산 프로퍼티나 static을 사용해서 구현한다.

  • alamofire 사용시 router 구현해 봤다.
import Foundation
import Alamofire
enum APIRouter: URLRequestConvertible {
 // MARK: - Property
  static let user = UserDefaultService.shared.getUser()
  var baseURL: URL {
    return URL(string: "http://localhost:8080/api")!
  }
  // MARK: - Cases
  // auth
  case emailSignIn(email: String, username: String, password: String)
  case emailLogin(email: String, password: String)
  // todo
  case getTasks
  case postTask(contents: String, date: String)
  case updateTodo(contents: String, taskId: Int)
  case deleteTodo(taskId: Int)
  case checkTodo(taskId: Int)
  // timer
  case postTime(second: Int)
  case getTodayTime
  // board, group
  case getClubs
  case createClub(memberID: Int, clubName: String, numberOfMember: Int, clubInfo: String)
  case singInClub(clubId: Int)
  // MARK: - End Point
  var endPoint: String {
    guard let userId = APIRouter.user?.userInfo.id else { return ""}
    switch self {
    // auth
    case .emailSignIn:

    case .emailLogin:

    case .getTasks, .postTask:

    case let .updateTodo(_, taskId), let .deleteTodo(taskId):

    }
  }
  // MARK: - Method

  var parameters: Parameters? {
    var params = Parameters()
    switch self {

    case let .emailSignIn(email, username, password):
      params["email"] = email
      params["username"] = username
      params["password"] = password

      params["email"] = email

      params["contents"] = contents
      params["date"] = date
    case let .updateTodo(contents, _):
      params["contents"] = contents
    case .deleteTodo:
      return nil
    case .checkTodo:
      return nil
    // timer
    case let .postTime(second):
      params["second"] = second
    case .getTodayTime:

    // board, group
    case .getClubs:
      return nil
    case let .createClub(memberID, clubName, numberOfMember, clubInfo):
      params["memberID"] = memberID
      params["clubName"] = clubName
      params["numberOfMember"] = numberOfMember
      params["clubInfo"] = clubInfo
    case .singInClub:
      return nil
    }
    return params
  }
  // MARK: - URL Request
  func asURLRequest() throws -> URLRequest {
    var urlRequest = URLRequest(url: baseURL.appendingPathComponent(endPoint))
    urlRequest.method = self.method
    switch self.method {
    case .get:
      return urlRequest
    case .post:
      if let parameters = parameters {
        urlRequest.httpBody = try JSONSerialization.data(withJSONObject: parameters)
      }
    case .put:
      urlRequest.httpBody = try JSONEncoding.default.encode(urlRequest, with: parameters).httpBody
    default:
      return urlRequest
    }
    return urlRequest
  }
}

asURLRequest() 함수에서 method별로 구현해주기도 하고 case 별로 구현해주는 방법도 있다.
header를 넣어 주는 과정에서

urlRequest.headers = self.headers

처럼 시도해서 오류가 발생했었다ㅜ

urlRequest.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")

setValue를 사용해서 구현해줘야한다.
