Question

I am using Flask and I return an XML file from a get request. How do I set the content type to xml ?

e.g.

@app.route('/ajax_ddl')
def ajax_ddl():
    xml = 'foo'
    header("Content-type: text/xml")
    return xml

Answer 1

Try like this:

from flask import Response
@app.route('/ajax_ddl')
def ajax_ddl():
    xml = 'foo'
    return Response(xml, mimetype='text/xml')

The actual Content-Type is based on the mimetype parameter and the charset (defaults to UTF-8).

Response (and request) objects are documented here: http://werkzeug.pocoo.org/docs/wrappers/
