I making an Ionic 3 app. I have the following JSON object:
{
"player": {
"username": "thelegend",
"platform": "xbox",
"stats": {
"normal": {
"shots": 5,
"wins": 66
},
"hard": {
"shots": 5,
"wins": 77
}
}
}
}
I want to acces the following data from the JSON object:
stats: {normal:{ shots: "58", wins: "54"}, hard: {shots "34", wins: "43"}
This is my rest provider method in my Ionic 3 app:
getStats(){
return this.http.get(this.apiUrl).subscribe(data => {
console.log(data);
});
}
I call this method at a specific page:
ionViewDidLoad() {
this.getData();
}
getData(){
return this.results = this.rest.getStats();
}
The api is working great and I can see the data in my Chrome developer tools. Now I want to bind this data on the view like this:
<ion-card>
<ion-card-header>
Wins
</ion-card-header>
<ion-card-content>
{{results}}
</ion-card-content>
</ion-card>
When I run the app it shows [object object]. I tried {{results.player.stats}} but it didn't work.
How can I bind the stats values on my view and access this?
Kind regards
you need to convert http response to json:
getStats(){
return this.http.get(this.apiUrl).map(res => res.json()).subscribe(data => {
console.log(data);
});
}
The api that I used is not working properly I changed to another api and everything was working fine. Thanks for the help!

I am making an Android app using Rest API and getting data from my WordPress website.
I have implemented a post views functionality on my app and I am using the Post Views Counter plugin on my WordPress website. Now the problem is that when I browse post on desktop the number of post views is increasing but on my Android app when I open a post it doesn’t increase.
Is there any method that I can use in my Android app to increase post view as well?
I have tried this code i found on internet but not working:
add_action( 'rest_api_init', function () {
register_rest_route( 'base', '/views/(?P<id>\d+)', array(
'methods' => 'GET',
'callback' => 'post_view_counter_function',
));
});
function post_view_counter_function( WP_REST_Request $request ) {
$post_id = $request['id'];
if ( FALSE === get_post_status( $post_id ) ) {
return new WP_Error( 'error_no_post', 'Not a post id', array( 'status' => 404 ) );
} else {
$current_views = get_post_meta( $post_id, 'views', true );
$views = $current_views + 1;
update_post_meta( $post_id, 'views', $views );
return $views;
}
}
please help
I am working on HTML5 mobile app using jQuery mobile.
This is my code:
$(document).on("click","#send_mobile_number",function(){
var mobile = $('#mobile_number').val();
var user_id = sessionStorage.getItem("user_id");
$('.ui-loader').show();
$.ajax({
url: BASE_URL+'users/send_sms_code.php',
type: 'POST',
datatype: 'json',
data: "user_id="+user_id+"&mobile="+mobile+"&type=1",
async:false,
success: function (response) {
var data = jQuery.parseJSON(response);
$('.ui-loader').hide();
if(data.status == 'Fail') {
$('.very_mob_no_message').html('Sorry some error occurred,try again.');
}else{
$('#close_mob_popup').trigger('click');
setTimeout(function()
{
$('.click_mobile_verify').trigger('click');
}, 500);
$('#send_mobile_verify_span').hide();
$('#after_mobile_send_span').show();
$('#moble_number_div').hide();
$('#user_code_div').show();
$('#user_code').val(data.sms_code);
//alert(window.localStorage.getItem('mobile'));
//sessionStorage.setItem("mobile",mobile);
window.localStorage.setItem("mobile",mobile); // IT IS NOT WORKING
$('.very_mobile_message').html('Enter code which is <br/> sent to your mobile number.');
}
},
error: function (jqXHR, textStatus, errorThrown) {
//alert(jqXHR.status);
}
});
});
I want to store mobile number in session using window.localStorage.setItem("mobile",mobile);. It is working when I run on my browser but when I runt on mobile phone as APP it stop working. Why this happening. I am checking android phone.
Just use localStorage.mobile = "mobile". It's as simple as that. localStorage is a global object and can be accessed and manipulated as any other object. The only difference with regular objects is that it can store only strings.
You can then retrieve your value using alert( localStorage.mobile ); // will alert "mobile"
So finally found the solution, I need to set webSettings.setDomStorageEnabled(true); on android code and after this localstorage is working perfectlly.
I encountered a problem when I try to package my sencha-touch app using phonegap. Everything works fine except accessing WFS in phonegap. (And the app has no problem running in browser, WFS access is OK)
My phonegap version is 2.9; openlayer version is 2.13
Here I present my simple code. You can also check the example codes in the following site: http://openlayers.org/dev/examples/wfs-filter.html
var rootUrl = window.location.protocol + "//" + window.location.host + '/';
var map;
function init() {
map = new OpenLayers.Map({
div: "map",
layers: [
new OpenLayers.Layer.WMS(
"Natural Earth",
"http://demo.opengeo.org/geoserver/wms",
{ layers: "topp:naturalearth" }
),
new OpenLayers.Layer.Vector("WFS", {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
url: rootUrl + 'proxy.py?url=http://demo.opengeo.org/geoserver/wfs',
featureType: "tasmania_roads",
featureNS: "http://www.openplans.org/topp"
}),
styleMap: new OpenLayers.StyleMap({
strokeWidth: 3,
strokeColor: "#333333"
}),
})
],
center: new OpenLayers.LonLat(146.7, -41.8),
zoom: 6
});
}
In phonegap there's no problem accessing WMS, but when I try WFS, it never work.
Comparing to the link I showed you before, there's a road displayed in the map, and it is obtained through WFS. In my phonegap app, the road will not be displayed.
I'm wondering whether it is a WFS issue, or phonegap issue. Something is blocking my access to WFS in my phonegap app.
Please give me some suggestions and hints, guys! I will really appreciate it.
function getLayerList() {
$.ajax({ url: rootUrl + 'proxy.py?url=http://192.168.0.23/LBEService/Service1.svc/GetEventList',
//async: false,
data: JSON.stringify({}),
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (result) {
console.log(result);
$("#demo").html(result[0].event_NAME);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(thrownError);
}
}).done(function () {
});
}
Have you added the domain that is hosting the WFS to the white list?
http://docs.phonegap.com/en/1.9.0/guide_whitelist_index.md.html
On android PhoneGap window.location.protocol is 'file:' and window.location.hostname is "", so your app will probably be looking for file://proxy.py? which doesn't exist on your device.
To solve this issue I test the protocol, and set up OpenLayers.Proxy accordingly, thus:
if( location.protocol == 'file:' ) {
OpenLayers.ProxyHost = "";
} else {
OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";
}
So in your case, if protocol is 'file:', I think you need to drop 'proxy.py?'
Tip: debug your android app using Chrome on your PC (chrome://inspect/#devices) and you'll see the request that android is making.
i'm new at phonegap. any guide or example of the process of linking an api such as http://openweathermap.org/. want to get data from this api on android app
Use jQuery mobile to parse data from any API.
Follow the code and example JSON given below.
$.getJSON('ajax/test.json', function(data) {
var items = [];
$.each(data, function(key, val) {
items.push('<li id="' + key + '">' + val + '</li>');
});
$('<ul/>', {
'class': 'my-new-list',
html: items.join('')
}).appendTo('body');
});
This example, of course, relies on the structure of the JSON file:
{
"one": "Singular sensation",
"two": "Beady little eyes",
"three": "Little birds pitch by my doorstep"
}
Is it possible to communicate an android Application with cakePhp website and share data? If it is possible, I want to create an application that can login into the website; my doubt is:
How to pass user name and password from our application to cakephp websites login page? Can anybody show me an example program?
How cakephp controller handle this request and respond to this request? Please show me an example program?
(I am a beginner in android and cakephp.)
Quick answer -- YES!
We just finished pushing an Android app to the market place that does this exact thing. Here's how we did it:
1) Download and learn to use Cordova PhoneGap (2.2.0 is the latest version) within Eclipse. This makes the whole thing so much easier with just some HTML and a lot of Javascript.
2) In your JS, create methods that push the login information using AJAX parameters. Example:
document.addEventListener('deviceready', onDeviceReady, false);
function onDeviceReady() {
$("#login").click(function() {
$email = $("#UserEmail").val();
$pass = $("#UserPassword").val();
$.ajax({
url : yourURL + 'api/users/login',
async : false,
data : {
'email' : $email,
'password' : $pass
},
dataType : 'json',
type : 'post',
success : function(result) {
/**
* do your login redirects or
* use localStorage to store your data
* on the phone. Keep in mind the limitations of
* per domain localStorage of 5MB
*/
// you are officially "logged in"
window.location.href = "yourUrl.html";
return;
},
error : function(xhr, status, err) {
// do your stuff when the login fails
}
});
}
}
3) In Cake / PHP, your Users controller here will take the username and password data in the AJAX call and use that for its authentication.
<?php
class UsersController extends AppController {
public $name = 'Users';
public function beforeFilter() {
parent::beforeFilter();
$this->Auth->allow('api_login');
}
public function api_login() {
$this->autoRender = false;
if ($this->request->data && isset($this->request->data['email']) && isset($this->request->data['password'])) {
$arrUser = $this->User->find('all',array(
'conditions'=>array(
'email'=> $this->request->data['email'],
'password' => $this->Auth->password($this->request->data['password']),
)
)
);
if (count($arrUser) > 0) {
$this->Session->write('Auth.User',$arrUser[0]['User']);
// Do your login functions
$arrReturn['status'] = 'SUCCESS';
$arrReturn['data'] = array( 'loginSuccess' => 1,'user_id' => $arrUser[0]['User']['id'] );
} else {
$arrReturn['status'] = 'NOTLOGGEDIN';
$arrReturn['data'] = array( 'loginSuccess' => 0 );
}
} else {
$arrReturn['status'] = 'NOTLOGGEDIN';
$arrReturn['data'] = array( 'loginSuccess' => 0 );
}
echo json_encode($arrReturn);
}
}
?>
That's pretty much it. You are now authenticated to CakePHP.
You do not need to use "api_", you can use any function name you want, but this helped us keep a handle on what we allowed mobile users to do versus web users.
Now, these are just the building blocks. You basically have to create a whole version of your site on the phone using HTML and Javascript, so depending on your application it may be easier just to create a responsive design to your site and allow mobile browsing.
HTH!
Use Admad JWT Auth Plugin
If you use cakephp3 change your login function with this one :
public function token() {
$user = $this->Auth->identify();
if (!$user) {
throw new UnauthorizedException('Invalid username (email) or password');
}
$this->set([
'success' => true,
'data' => [
'token' => JWT::encode([
'sub' => $user['id'],
'exp' => time() + 604800
],
Security::salt())
],
'_serialize' => ['success', 'data']
]);
}
You can read this tutorial about REST Api and JWT Auth Implementation
http://www.bravo-kernel.com/2015/04/how-to-add-jwt-authentication-to-a-cakephp-3-rest-api/
if rebuild most of the view pages in cakephp into ajax will seem defeat the purposes of using cakephp as it is.
