python - Can't to get data from flask restful api. Angularjs -

i have simple restful api on flask.

#!flask/bin/python flask import flask, jsonify, response  app = flask(__name__)  @app.route('/todo/api/v1.0/notes', methods=['get']) def get_tasks():     return jsonify({'key': 'value'})  if __name__ == '__main__':     app.run(debug=true) 

and have angularjs controller this:

var app = angular.module('notesapp',['angular-markdown-editable']);  app.controller('notescontroller',function($scope, $http, $window){      $http({         method: 'get',         url: "http://127.0.0.1:5000/hello"     }).then(function successcallback(response) {         $window.alert(":)");      }, function errorcallback(response) {         $window.alert(":(");     }); }); 

problem: not receive objects (errorcallback executes).

when try:

curl -i http://127.0.0.1:5000/hello 

i have result:`

http/1.0 200 ok content-type: text/html; charset=utf-8 content-length: 5 server: werkzeug/0.11.10 python/2.7.6 date: wed, 25 may 2016 03:09:54 gmt  hello 

when app send request server have:

 * running on http://127.0.0.1:5000/ (press ctrl+c quit)  * restarting stat  * debugger active!  * debugger pin code: 319-334-341  127.0.0.1 - - [25/may/2016 05:58:20] "get /hello http/1.1" 200 -
