aia_chaser_http 0.1.0

package:http client adapter for aia_chaser, enabling scoped AIA intermediate certificate chasing and transparent retry-once.

aia_chaser_http

A drop-in http.Client implementation for aia_chaser that enables scoped Authority Information Access (AIA) intermediate certificate chasing and transparent retry-once resilience for Flutter and Dart.

---

The Problem

When interacting with backend servers that omit intermediate CA certificates, package:http throws:

ClientException: HandshakeException: CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate

aia_chaser_http safely resolves this by chasing intermediate certificates via AIA, validating against the system root store, and retrying failed requests once upon successful chain completion.

Quick Start

1. Initialize AIA Chaser

import 'package:aia_chaser/aia_chaser.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await AiaChaser.initialize(AiaConfig(
    hosts: {
      'api.example.com': const HostPolicy(
        chase: true,
        retryOnce: true, // Transparently retry upon validation
      ),
    },
  ));

  runApp(const MyApp());
}

2. Use AiaHttpClient

import 'package:aia_chaser_http/aia_chaser_http.dart';

final client = AiaHttpClient();

// Safe requests with automatic AIA recovery
final response = await client.get(Uri.parse('https://api.example.com/v1/data'));
print(response.body);

client.close();

You can also pass an existing http.Client to wrap:

final customClient = AiaHttpClient(myExistingClient);
