Android模拟器运行Flutter代码调用OpenAI API时连接超时求助

环境信息 #

• Android Studio版本：Electric Eel | 2022.1.1 Patch 2
• Flutter版本：3.7.8

问题描述 #

代码在本地运行正常，但在模拟器中调用https://api.openai.com/v1/chat/completions接口时，始终返回connection timed out错误。

相关代码 #

Future<Album> fetchAlbum() async {
  final response = await http.post(
    Uri.parse('https://api.openai.com/v1/chat/completions'),

    headers: {
      'Content-Type': 'application/json',
      'Authorization': 'Bearer $apiKey',
    },
    body: jsonEncode({
      "model": "gpt-3.5-turbo",

      "messages": [
        {
          "role": "user",
          "content": '$prompt',
        }
      ]
    }),
  );

  if (response.statusCode == 200) {
    return Album.fromJson(jsonDecode(response.body));
  } else {
    throw Exception('Failed to load album');
  }

}


class Album{ ... }    //details omitted


void main() => runApp(const MyApp());

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override

    super.initState();
    futureAlbum = fetchAlbum();
  }

  @override

    return MaterialApp(

      theme: ThemeData(
        primarySwatch: Colors.blue,

                  ],
                );
              } else if (snapshot.hasError) {
                  return Text('${snapshot.error}');
              }

              // By default, show a loading spinner.
              return const CircularProgressIndicator();
            },
          ),
        ),
      ),
