Bottle + GEVENT Unicode-Codierung Fehler

Ich versuche, den WebSocket-Beispiel-Code aus diesem Handbuch auszuführen: http://bottlepy.org/docs/dev/async.html Bottle + GEVENT Unicode-Codierung Fehler

Den Code, die auf der Website funktioniert nicht. Ich habe versucht, es so minimal wie möglich zu schreiben, aber es hat nichts verändert. Hier ist meine endgültige Version.

Server-Seite:

from bottle import request, Bottle, abort 
app = Bottle() 

@app.route('/websocket') 
def handle_websocket(): 
    return "Hello" 

from gevent.pywsgi import WSGIServer 
from geventwebsocket import WebSocketError 
from geventwebsocket.handler import WebSocketHandler 
server = WSGIServer(("0.0.0.0", 8080), app, 
       handler_class=WebSocketHandler) 
server.serve_forever()

Client-Seite:

<!DOCTYPE html> 
<html> 
<head> 
<meta charset="UTF-8"> 
    <script type="text/javascript"> 
    var ws = new WebSocket("ws://localhost:8080/websocket"); 
    </script> 
</head> 
</html>

Der Server druckt die folgenden Fehler Spur. Was läuft falsch?

geventwebsocket hat Python 3 noch nicht vollständig unterstützt (Stand 2. Mai 2016).

Nur eine Vermutung, aber haben Sie versucht:

@app.route('/websocket') 
def handle_websocket(): 
    return b"Hello"

(Auf einer Seite beachten, wenn Sie über die Leistung kümmern, dann sollten Sie einen Array zurück, keinen String return [b"Hello"].)

Das Problem ist nicht mit OPs app, es mit geventwebsocket ist. –
