我无法将我的Django后端连接到Web上的Flutter前端。我还没有在Android或iOS上测试过。

我希望能够进行API调用并让它返回一个可以转换为json的响应。然而，无论我尝试过什么，它都会抛出错误。我尝试过将其转换为https请求，但没有成功。

如果有人需要Django方面的任何东西，请告诉我

这是错误的样子：

这是一个代码片段

import 'package:http/http.dart' as http;

var url2 = 'https://0.0.0.0:8809/test/';
              try{
                response = await http.get(Uri.parse(url2));
                print(response.body);
              }
              catch(exception){
                print('could not access');
                    response = await http.get(Uri.parse(url2));
              }

            },

我让它把错误打印出来了。
