4주차

4주차 세미나에서는 Alamofire 를 통해 날씨API 를 연결하였습니다. TableView Cell 에 날씨 API를 연결하여 네트워크 통신을 구현하였습니다.

주요코드

네트워크 통신에서 가장 주요한 코드는 WeatherService 입니다 :)

final class WeatherService {
    
    let baseURL = "https://api.openweathermap.org/data/2.5/weather?"
    static let shared = WeatherService()

    private init() {}

    func getWeather(city : String, completion : @escaping (NetworkResult<Any>) -> Void) {
        let url = "https://api.openweathermap.org/data/2.5/weather"
        let header: HTTPHeaders = ["Content-Type" : "application/json"]
        let body: Parameters = [
            "q": city,
            "appid": "9c7fa18b50b00954d1159672fb66a924",
        ]

        let dataRequest = AF.request(url, method: .get,
                                     parameters : body,
                                     headers: header)

        dataRequest.responseData { response in
            switch response.result {
            case .success:
                guard let statusCode = response.response?.statusCode else { return }
                guard let value = response.value else { return }
                let networkResult = self.judgeStatus(by: statusCode, value)
                completion(networkResult)
            case .failure:
                completion(.networkErr)
            }
        }
    }
    private func judgeStatus(by statusCode: Int, _ data: Data) -> NetworkResult<Any> {
        switch statusCode {
        case 200: return isValidData(data: data)
        case 400...409: return isValidData(data: data)
        case 500: return .serverErr
        default: return .networkErr
        }
    }

    private func isValidData(data: Data) -> NetworkResult<Any> {
        let decoder = JSONDecoder()

        guard let decodedData = try? decoder.decode(Weathers.self, from: data) else { return .pathErr }

        return .success(decodedData as Any)
    }
}
