I like and upvoted  Simon Sapin s answer   I ended up taking a slightly different tack  however  and created my own decorator   from flask import Response from functools import wraps  def returns xml f        wraps f      def decorated function  args    kwargs           r   f  args    kwargs          return Response r  content type  text xml  charset utf-8       return decorated function   and use it thus    app route   ajax ddl    returns xml def ajax ddl        xml    foo      return xml   I think this is slightly more comfortable

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

You can try the following method python3 6 2    case one    app route   hello   def hello         headers    content-type   text plain    location   http   www stackoverflow       response   make response   lt h1 gt hello world lt  h1 gt   301      response headers   headers     return response   case two    app route   hello   def hello         headers    content-type   text plain    location   http   www stackoverflow com       return   lt h1 gt hello world lt  h1 gt   301 headers   I am using Flask  And if you want to  return json you can write this   import json     app route   search  lt keyword gt    def search keyword        result   Book search by keyword keyword      return json dumps result  200   content-type   application json     from flask import jsonify  app route   search  lt keyword gt    def search keyword        result   Book search by keyword keyword      return jsonify result

Usually you don   t have to create the Response object yourself because make response   will take care of that for you   from flask import Flask  make response                                       app   Flask   name                                                             app route                                                                   def index                                                                        bar     lt body gt foo lt  body gt                                                       response   make response bar                                                 response headers  Content-Type      text xml  charset utf-8                  return response     One more thing  it seems that no one mentioned the after this request  I want to say something   after this request     Executes a function after this request  This is useful to modify response objects  The function is passed the response object and has to return the same or a new one    so we can do it with after this request  the code should look like this   from flask import Flask  after this request app   Flask   name      app route      def index         after this request     def add header response           response headers  Content-Type      text xml  charset utf-8          return response     return   lt body gt foobar lt  body gt

As simple as this  x    some data you want to return  return x  200    Content-Type    text css  charset utf-8     Hope it helps  Update  Use this method because it will work with both python 2 x and python 3 x  and secondly it also eliminates multiple header problem   from flask import Response r   Response response  TEST OK   status 200  mimetype  application xml   r headers  Content-Type      text xml  charset utf-8  return r

Use the make response method to get a response with your data  Then set the mimetype attribute  Finally return this response    app route   ajax ddl   def ajax ddl        xml    foo      resp   app make response xml      resp mimetype    text xml      return resp   If you use Response directly  you lose the chance to customize the responses by setting app response class  The make response method uses the app responses class to make the response object  In this you can create your own class  add make your application uses it globally   class MyResponse app response class       def   init   self   args    kwargs           super MyResponse  self    init    args    kwargs          self set cookie  last-visit   time ctime     app response class   MyResponse
