Issue Description and Steps
I have this URL = https://thelot-lab.encoreent.rocks/bridge.php
with this content:
?php
header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: Cookie, X-API-KEY, Origin, X-CSRF-TOKEN, X-XSRF-TOKEN, X-Requested-With, Access-Control-Allow-Origin, Authorization, Content-Type, Accept, Access-Control-Request-Method");
header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE, PATCH");
header("Allow: GET, POST, OPTIONS, PUT, DELETE, PATCH");
header('Access-Control-Allow-Credentials: true');
echo "Hola Mundo";
And I have this code in flutter:
Dio _dio = Dio();
var result = await _dio.post(
"https://thelot-lab.encoreent.rocks/bridge.php",
options: Options(headers: {"token":"1234567890"}),
);
print(result.data);
And the browser console show me:
browser_adapter.dart:94 OPTIONS https://thelot-lab.encoreent.rocks/bridge.php net::ERR_HTTP2_PROTOCOL_ERROR
errors.dart:145 Uncaught (in promise) Error: DioError [DioErrorType.RESPONSE]: XMLHttpRequest error.
