SOLVED Python get HTTP

pavelprosto

I am trying to accessing web resources.
Main.qml

import QtQuick 2.7
import Ubuntu.Components 1.3
//import QtQuick.Controls 2.2
import QtQuick.Layouts 1.3
import Qt.labs.settings 1.0
import io.thp.pyotherside 1.3

MainView {
    id: root
    objectName: 'mainView'
    applicationName: 'example-web.yourname'
    automaticOrientation: true

    width: units.gu(45)
    height: units.gu(75)

    Page {
        anchors.fill: parent

        header: PageHeader {
            id: header
            title: i18n.tr('Example Web')
        }

        Label {
            id: label1
            anchors {
                top: header.bottom
                left: parent.left
                right: parent.right
                bottom: parent.bottom
            }
            text: 'Get Web'
            verticalAlignment: Label.AlignVCenter
            horizontalAlignment: Label.AlignHCenter
        }
    }

    Python {
        id: python
        Component.onCompleted: {
            addImportPath(Qt.resolvedUrl('../src/'));

            importModule('example', function() {
                python.call('example.speak',[], function(returnValue) {
                    console.log(returnValue);
                    label1.text=returnValue;
                })
            });
        }

        onError: {
            console.log('python error: ' + traceback);
        }
    }
}

example.py

import urllib.request
import urllib3

def speak():
  try:
    source = urllib.request.urlopen("http://webcode.me")
  except Exception as e:
    return str(e)
  else:
    html_bytes = source.read()
    html_str = html_bytes.decode("utf8")
    source.close()
    return html_str

def speak2():
  http = urllib3.PoolManager()
  try:
    source = http.request('GET', 'http://webcode.me')
  except Exception as e:
    return str(e)
  else:
    html_str = source.data.decode('utf-8')
    return html_str

Both examples work on a computer(clickable desktop), but when I run them on a phone, I get errors:
on urllib:

<urlopen error [Errno -3] Temporary failure in name resolution>

on urllib3:

HTTPConnectionPool(host='webcode.me', port=80): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0xa8111390>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution',))

How can fix it? Help me please.

Find the * .apparmor file in the project folder.
Add permissions:

{
    "policy_groups": [
        "content_exchange",
        "content_exchange_source",
        "networking",
        "webview"
    ],
    "policy_version": 16.04
}

After that the program will work
