Flutter 网络请求框架封装，35岁老年程序员的绝地翻身之路

import 'package:dio/dio.dart';
 
class HttpClient {
  static const baseUrl = 'https://example.com/api';
  final Dio dio = Dio(BaseOptions(baseUrl: baseUrl));
 
  Future<Response> get(String path, {Map<String, dynamic>? queryParameters, Options? options}) async {
    return dio.get(path, queryParameters: queryParameters, options: options);
  }
 
  Future<Response> post(String path, {data, Options? options}) async {
    return dio.post(path, data: data, options: options);
  }
 
  Future<Response> put(String path, {data, Options? options}) async {
    return dio.put(path, data: data, options: options);
  }
 
  Future<Response> delete(String path, {data, Options? options}) async {
    return dio.delete(path, data: data, options: options);
  }
}
 
// 使用示例
void main() async {
  HttpClient httpClient = HttpClient();
  try {
    Response response = await httpClient.get('/some-endpoint');
    print('Response status: ${response.statusCode}');
    print('Response data: ${response.data}');
  } catch (e) {
    print('Error: $e');
  }
}

这个示例代码展示了如何使用Dio库来封装一个简单的HTTP客户端，并提供了对GET、POST、PUT和DELETE请求的支持。这样的封装可以减少重复代码，提高代码的可维护性和可读性。在实际项目中，可以根据具体需求添加更多功能，比如请求拦截器、响应拦截器、错误处理等。
