Flutter add client certificate to request using http.dart


I'm trying to load a client certificate to a http.client from the http.dart package.

I'v seen multiple answers on how to do it using the HttpClient class, like this answer: Flutter add self signed certificate from asset folder, which basicaly suggests to do the following code

ByteData data = await rootBundle.load('assets/raw/certificate.pfx');
SecurityContext context = SecurityContext.defaultContext;
context.useCertificateChainBytes(data.buffer.asUint8List());
context.usePrivateKeyBytes(data.buffer.asUint8List());
client = HttpClient(context: context);

But I must use the http.dart package since i have a function that accepts a http.client something like this

import 'package:http/http.dart' as http;

var httpClient = http.Client();
// i'd like to configure this httpClient to use a specific client certificate

var client = MyClient(httpClient);

....

MyClient (http.Client? httpClient) {
    -- some constructor logic --
}

Is there any way to configure a http.client to use a client certificate?

Thanks.


Solution

  • Don't use the http.Client() constructor. Instead, construct an IOClient (which is a subclass of Client as can be used instead). Pass in your HttpClient.

    import 'dart:io';
    
    import 'package:http/io_client.dart';
    
    void main() async {
      final context = SecurityContext.defaultContext;
      // modify context as needed
      final httpClient = HttpClient(context: context);
      final client = IOClient(httpClient);
    
      await client.get(Uri.parse('https://somewhere.io'));
    }
