Widget js callback - Ajax POST violates same-origin policy?!

Community Support
1

Hello

I have embedded a bokeh slider into a flask template, and would like to send a POST Ajax request within its callback.

However that seems to infringe the same-origin policy, even if it all is happening on localhost. (see here and here for details of the issue).

Any clue why is that, and if it could be solved? Thanks

Code snippet from the slider’s callback:

$.ajax({

type: 'POST',

contentType: 'application/json',

url: "http://127.0.0.1:5000/server_calculations",

data: slider_value, //this is simply the value of the slider's position

dataType: 'json',

});

And as a side note, this is calling to the same page where the widget is embedded

data: slider_value, //this is simply the value of the slider's position

dataType: 'json',

And problem solved credit to this SO post:

solution is to remove the URL from the post request

$.ajax({

type: 'POST',

contentType: 'application/json',

// comment this out: url: "[http://127.0.0.1:5000/server_calculations](http://127.0.0.1:5000/server_calculations)",

data: slider_value, //this is simply the value of the slider's position

dataType: 'json',

});
