Flask 보기에서 스트리밍된 실시간 데이터를 어떻게 표시할 수 있나요?

# App
app = flask.Flask(__name__)

# Streaming view
@app.route('/')
def index():
    def generate():
        # Simulate data generation
        for i in range(500):
            yield str(i) + '<br/>\n'
    return flask.Response(generate(), mimetype='text/html')

# Run the app
app.run(debug=True)

<!-- Template -->
<p>Latest output: <span>

<p>All output:</p>
<iframe src=&quot;{{ url_for('stream') }}&quot;></iframe>

@app.route('/stream')
def stream():
    @stream_with_context
    def generate():
        yield '<link rel=stylesheet href=&quot;{{ url_for('static', filename='stream.css') }}&quot;>'
        for i in range(500):
            yield '<p>{{ i }}: {{ s }}</p>\n'.format(i=i, s=math.sqrt(i))
            sleep(1)

body {
  font-family: sans-serif;
}
p {
  margin-bottom: 10px;
}
