## 1. API 구조 ### 기본 DIO 패턴 ```dart import 'package:dio/dio.dart'; class ApiService { static ApiService? _instance; late Dio _dio; ApiService._internal() { _dio = Dio( BaseOptions( baseUrl: 'baseurl', connectTimeout: const Duration(seconds: 30), receiveTimeout: const Duration(seconds: 30), headers: {'Content-Type': 'application/json'}, ), ); } static ApiService get instance { _instance ??= ApiService._internal(); return _instance!; } Future<Response> get( String path, { Map<String, dynamic>? queryParameters, Options? options, CancelToken? cancelToken, ProgressCallback? onReceiveProgress, }) async { try { final response = await _dio.get( path, queryParameters: queryParameters, options: options, cancelToken: cancelToken, onReceiveProgress: onReceiveProgress, ); return response; } catch (e) { rethrow; } } Future<Response> post( String path, { dynamic data, Map<String, dynamic>? queryParameters, Options? options, CancelToken? cancelToken, ProgressCallback? onSendProgress, ProgressCallback? onReceiveProgress, }) async { try { final response = await _dio.post( path, data: data, queryParameters: queryParameters, options: options, cancelToken: cancelToken, onSendProgress: onSendProgress, onReceiveProgress: onReceiveProgress, ); return response; } catch (e) { rethrow; } } } ``` ```dart class ApiRepository { static final ApiService _apiService = ApiService.instance; //리스트 형일때 static Future<List<Item>> fetchItemssData() async { List<Item> temp = []; try { final response = await _apiService.get('/items'); response.data.toList().forEach((element) { temp.add(Item.fromJson(element)); }); return temp; } catch (e) { return temp; } } //일반모델 static Future<Item> fetchItemssData() async { Item temp = Item(); try { final response = await _apiService.get('/items'); temp = Item.fromJson(response.data); return temp; } catch (e) { return temp; } } } ```
