Http2Adapter

A Dio HttpClientAdapter which implements Http/2.0 .

Getting Started

Install

dependencies:
  dio_http2_adapter: x.x.x  #latest version

Usage

import 'package:dio/dio.dart';
import 'package:dio_http2_adapter/http2.dart'; 

main() async {
  var dio = Dio()
    ..options.baseUrl = "https://www.ustc.edu.cn/"
    ..httpClientAdapter = Http2Adapter();

  Response<String> response;
  response = await dio.get("/?xx=6");
  print(response.data);
  response = await dio.get("2062/list.htm");
  print(response.data);
}

ConnectionManager

ConnectionManager is used to manager the connections that should be reusable. The main responsibility of ConnectionManager is to implement a connection reuse strategy for http2.

dio.httpClientAdapter = Http2Adapter(
  ConnectionManager(
    idleTimeout: 10000,
    /// Ignore bad certificate
    onClientCreate: (_, clientSetting) => clientSetting.onBadCertificate = (_) => true,
  ),
);

• idleTimeout： Sets the idle timeout(milliseconds) of non-active persistent connections. For the sake of socket reuse feature with http/2, the value should not be less than 1000 (1s).
• onClientCreate：Callback when socket created. We can set trusted certificates and handler for unverifiable certificates.

You can also custom a connection manager with a specific connection reuse strategy by implementing the ConnectionManager.
