如何在Flutter中实现网络请求

在Flutter中实现网络请求有很多模块，可以使用http模块，也可以使用dio模块。

具体的用法在https://pub.dev/上面有，我们以前的的项目中用的是Dio库，它支持get post put delete还支持文件的上传下载

import 'package:dio/dio.dart';

final dio = Dio();

void getHttp() async {
  final response = await dio.get('https://dart.dev');
  print(response);
}


import 'package:dio/dio.dart';

class HttpsClient {
  static String domain = "https://xiaomi.itying.com/";
  static Dio dio = Dio();
  HttpsClient() {
    dio.options.baseUrl = domain;
    dio.options.connectTimeout = const Duration(milliseconds: 5000); //5s
    dio.options.receiveTimeout = const Duration(milliseconds: 5000);
  }

  Future get(apiUrl) async {
    try {
      var response = await dio.get(apiUrl);
      return response;
    } catch (e) {
      print("请求超时");
      return null;
    }
  }

  Future post(String apiUrl, {Map? data}) async {
    try {
      var response = await dio.post(apiUrl, data: data);
      return response;
    } catch (e) {
      print("请求超时");
      return null;
    }
  }
}
