Retrieving the response body from an HttpClientResponse

Question

I\'m trying to write some tests for my Dart server application, and I\'ve been using the HttpClient class (along with the related HttpClientRequest and HttpClientResponse cl

Answer 1

The HttpClientResponse object is a Stream, so you can just read it with the listen() method:

response.listen((List data) {
  //data as bytes
});

You can also use the codecs from dart:convert to parse the data. The following example reads the response contents to a String:

import 'dart:io';
import 'dart:convert';
import 'dart:async';

Future readResponse(HttpClientResponse response) {
  final completer = Completer();
  final contents = StringBuffer();
  response.transform(utf8.decoder).listen((data) {
    contents.write(data);
  }, onDone: () => completer.complete(contents.toString()));
  return completer.future;
}
