No idea what you are asking

For this request, I can get the response header and status code information when using JavaScript.
However, when using dio to send the request and parse the response, an exception is thrown, and I cannot get any information including the status code and response header except an error message in the onError method.

[Nondirectional]

The error is thrown when dio parses the response body. I want to know why the response cannot be parsed normally in dio/dart

Please provide a runnable minimal reproducible example.

Please provide a runnable minimal reproducible example.

sorry,my bad.

that is example:

      Dio dio = Dio(BaseOptions(
        baseUrl: "http://memos.w-wbr.space",
        connectTimeout: const Duration(seconds: 5),
        receiveTimeout: const Duration(seconds: 5),
      ));
      dio.interceptors.add(InterceptorsWrapper(onError: (error,handler) {
        print(error.message);
        print(error.stackTrace);
        print(error.response);
      }));
      Response? response = await dio.post("/api/v1/auth/status");
      print(response.data);

I realized that it might be a problem with the native http library. When I use the Dev tools running on a Windwos/Android device to view the request, I cannot see the response header.

[AlexV525]

The exception is thrown from the underlying HTTP foundation, rather than the dio itself.

void main() async {
  final client = HttpClient();
  final request = await client.postUrl(
    Uri.parse('http://memos.w-wbr.space/api/v1/auth/status'),
  );
  final response = await request.close();
  print(response);
}

Consider submitting the issue to the Dart SDK.
