Struggling to view embedded script from running bokeh server app w/o Flask

Jonas_Grave_Kristens · March 2, 2018, 3:52pm

Hi,

I’m trying to embed a running app from bokeh server into a html page without the use of Flask. I’m able to get the script into the part of the Jinja2 template, but connection is refused when I open the created html file. The error I get is:

2018-03-02 16:42:32,788 Refusing websocket connection from Origin ‘file://’; use --allow-websocket-origin= to permit this; currently we allow origins set([‘localhost:5003’])

My script for running and making the html document is as follows:

import io

from bokeh.plotting import figure
from bokeh.resources import INLINE
from bokeh.embed import file_html, server_document, server_session
from bokeh.client import pull_session

TEMPLATE = Template(’’’

</head>
<body>

    <h1>Header</h1>
    <p>Test embed slider.py</p>

    {{ script|safe }}

</body>

''' )

url = ‘http://localhost:5003/sliders’
#session = pull_session(url=url)
#script = server_session(None, session.id, url=url)
script = server_document(url)

html = TEMPLATE.render(script = script)
with io.open(“sliders_embed.html”, mode=‘w+’, encoding=‘utf-8’) as f:
f.write(html)

``

Hence when I view sliders_embed.html in the browser I get the error stated in the beginning. I have tried using server_document or a combination of pull_session and server_session, but it gives the same error.

Any help would be appreciated. Thanks.

Hi,

You need to tell the Bokeh server to accept WebSocket connections from whatever the URL of the embedding page is. By default the Bokeh server is conservative and does not allow arbitrary connections. As the console error message mentions, you can use --allow-websocket-origin to specify allowed origin URLs when you run "bokeh serve"

Thanks,

Bryan

Of course… I needed to use --allow-websocket-origin=* in order to get to work. Thanks!

That will certainly work, but note that it will allow WS connections from anywhere. If you can be more specific than that, I would recommend it. Generally speaking, the value should be URL that users will navigate to, i.e. the "Origin" (you can add multiple on the command line too, if needed)

Thanks,

Sorry, I am not so good at this network syntax… From other bokeh apps/scripts I have worked on I have figured out using the --allow-websocket-orign=ip:port when I run the bokeh serve command.

However, in this case I try to generate a html file with the link to the server embedded (without Flask). Hence, one points a browser to a file://<name_of_file.html> (the reason for doing it this way is just the way the framework is where I’ll try and use it)

The only way I could the the bokeh server to allow the embedded link to read the server doc was by using --allow-websocket-origin=*

If I use bokeh serve sliders.py --allow-websocket-origin=‘file:///xxxxx/xxx/sliders_embed.html’ I get an error: ERROR:Invalid port in host value: file:///xxxxx/xxx/sliders_embed.html

Oh, if you are just viewing local HTML files in a browser directly then * may be the best bet after all. My previous advice was assuming the apps were being embedded in a page that was served, not a local HTML file loaded directly.

THanks,

Sorry, I am not so good at this network syntax.... From other bokeh apps/scripts I have worked on I have figured out using the --allow-websocket-orign=ip:port when I run the bokeh serve command.

However, in this case I try to generate a html file with the link to the server embedded (without Flask). Hence, one points a browser to a file://<name_of_file.html> (the reason for doing it this way is just the way the framework is where I'll try and use it)

The only way I could the the bokeh server to allow the embedded link to read the server doc was by using --allow-websocket-origin=*

If I use bokeh serve sliders.py --allow-websocket-origin='file:///xxxxx/xxx/sliders_embed.html' I get an error: ERROR:Invalid port in host value: file:///xxxxx/xxx/sliders_embed.html

That will certainly work, but note that it will allow WS connections from anywhere. If you can be more specific than that, I would recommend it. Generally speaking, the value should be URL that users will navigate to, i.e. the "Origin" (you can add multiple on the command line too, if needed)

Thanks,

Bryan

By default the Bokeh server is conservative and does not allow arbitrary connections. As the console error message mentions, you can use --allow-websocket-origin to specify allowed origin URLs when you run "bokeh serve"
