WebSocket, Invalid request method, uri = http://127.0.0.1:8989/

[Jon Kleiser]

Hi,

I have written (stolen) a simple stand-alone WebSocket client that works fine when connecting to e.g. ws://demos.kaazing.com/echo, but when I try to connect to a local WebSocket server written i Pony, I get this:

Unhandled exception:

HttpException: Invalid request method, uri = http://127.0.0.1:8989/

#0      _HttpParser._doParse (dart:io/http_parser.dart:428)

#1      _HttpParser._parse (dart:io/http_parser.dart:318)

#2      _HttpParser._onData (dart:io/http_parser.dart:804)

My Dart progam looks like this:

import "dart:io";

void receivedData(data) {

  print("Received: $data");

}

main() async {

  var socket = await WebSocket.connect("ws://127.0.0.1:8989/");

  socket.listen((data) {

    receivedData(data);

  });

  

  for (int i=1; i<4; i++) {

    socket.add("dart-$i");

  }

}

Can you spot any problems with this code?

I have reported the problem to the developer of the Pony WebSocket library, here:

The "Invalid request method" problem was solved by converting all headers to lower case in the Pony WebSocket library.

Thanks for following up with the Pony developers.

Looks like Dart and Pony now work well together.
