TrustAPP_httpdns_example

Demonstrates how to use the TrustAPP_httpdns plugin with various network libraries.

Features

This example demonstrates:

• HTTPDNS initialization and configuration
• Domain name resolution (IPv4 and IPv6)
• Integration with multiple network libraries:
  • Dio
  • HttpClient
  • http package
• Custom HTTP client adapter for HTTPDNS
• Real HTTP requests using HTTPDNS resolution

Getting Started

1. Replace the SDK init parameters in lib/main.dart with your own values:

   await TrustAPPHttpdns.init(
     appId: 'YOUR_APP_ID',
     primaryServiceHost: 'httpdns-a.example.com',
     backupServiceHost: 'httpdns-b.example.com',
     servicePort: 443,
     secretKey: 'YOUR_SIGN_SECRET', // optional if sign is enabled
   );
   

2. Install dependencies:

   flutter pub get
   

3. Run the app:

   flutter run
   

4. Try the features:

   • Enter a URL and select a network library (Dio/HttpClient/http)
   • Tap "Send Request" to make an HTTP request using HTTPDNS
   • Tap "HTTPDNS Resolve" to test domain resolution directly

Implementation Details

The example uses a modern approach with HttpClient.connectionFactory to integrate HTTPDNS:

• See lib/net/httpdns_http_client_adapter.dart for the implementation
• This approach avoids the complexity of local proxy servers
• Works seamlessly with Dio, HttpClient, and http package

Note

The values in this example are placeholders. Use your own platform app configuration.
