Using flask, ajax - get response header value

Question

I'm sending request through ajax, sending response through Flask.

This is my code

ajax

'''

$.ajax({
    url:'/get',
    type: "post",
    data: {"hi":"hello"},
    success(function(data, textStatus, jqXHR){
        console.log(jqXHR.getResponseHeader('token'));
    })
})

'''

Flask '''

@app.route('/get', methods=['POST'])
def hello():
    data = {'result': 0}
    resp = make_response(data)
    resp.headers['hi'] = 123
    return resp'''

If I run this, I can see response header ('hi', 123) in chrome inspection. But NO CONSOLE LOG.

Is there anything wrong with my code?

There's no token response header in your server response, try reading hi header:

$.ajax({
    url:'/get',
    type: "post",
    data: {"hi":"hello"},
    success(function(data, textStatus, jqXHR){
        // this line: 
        console.log(jqXHR.getResponseHeader('hi'));
    })
})
