Dohun-choi commented 2 weeks ago

Steps to reproduce

I send a HTTP request to https://cataas.com/cat and i print request and response by using dio package.

[239, 191, 189, 239, 191, 189, 239, 191, 189, 239, 191, 189, 0, 67, 0, 6, 4, 5, 6, 5, 4, 6, 6, 5, 6, 7, 7, 6, 8, 10]

i really don't no about this issue...

Expected results

just print...

Actual results

Code sample

```dart import 'package:dio/dio.dart'; import 'package:flutter/material.dart'; import 'package:flutter_dotenv/flutter_dotenv.dart'; final api = Dio( BaseOptions( baseUrl: dotenv.get('BASE_URL'), ), ); final interceptors = InterceptorsWrapper( onRequest: (RequestOptions options, RequestInterceptorHandler handler) { debugPrint('REQUEST[${options.method}] => PATH: ${options.path}'); debugPrint("${options.data}"); return handler.next(options); }, onResponse: (Response response, ResponseInterceptorHandler handler) { debugPrint( 'RESPONSE[${response.statusCode}] => PATH: ${response.requestOptions.path}'); debugPrint("${response.data}"); return handler.next(response); }, onError: (DioException error, ErrorInterceptorHandler handler) { debugPrint( 'ERROR[${error.response?.statusCode}] => PATH: ${error.requestOptions.path}'); return handler.next(error); }, ); ```
