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;
}
}
}
