How can I identify requests made via AJAX in Python's Flask?

Question

I\'d like to detect if the browser made a request via AJAX (AngularJS) so that I can return a JSON array, or if I have to render the template. How can I do this?

Answer 1

for future readers: what I do is something like below:

request_xhr_key = request.headers.get('X-Requested-With')
if request_xhr_key and request_xhr_key == 'XMLHttpRequest':
   #mystuff

   return result
abort(404,description="only xhlhttprequest is allowed")

this will give an 404 error if the request header doesn't contain 'XMLHttpRequest' value.
