Post request not working - post

i've got an android app and a really simple web service that make an insert in a DB with 3 values.
the titanium code is most like the example given on the docs
var xhr = Ti.Network.createHTTPClient();
xhr.onload = function(e) {};
xhr.open('POST','http://www.micheleantonaci.altervista.org/test/foobar.php');
xhr.send({
"latitude":00100,
"longitude":10000,
"type":'From Nexus'
});
and the web service is just
<?php
$con=mysql_connect('http://www.micheleantonaci.altervista.org/','***','***');
mysql_select_db('***',$con);
if(isset($_REQUEST['submit']))
{
$latitude=$_POST['latitude'];
$longitude=$_POST['longitude'];
$kind=$_POST['type'];
$sql="insert into foobar (latitude,longitude,type) values ('$latitude','$longitude','$kind')";
$res=mysql_query($sql) or die (mysql_error());
}
?>
now, when i try the webservice giving the values with the browser it works good, but with the app I get no results at all, any suggestions? tha app doesn't crash or log any error

You must use PHP function json_decode to get values.

Try adding the header like this:
xhr.setRequestHeader("Content-Type", "application/json");
You should also do a var_dump($_POST) in your PHP to see what's in it, not sure you'll get your stuff in separated variables...

When I see a problem like this, I setup 'Charles' or a similar proxy and have the device send it's request through the proxy. Then you can see if the device is send what is expected.
You could also try
xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

The code is right, the problem was on the framework itself, at that day the post method wasn't working.
Nowadays it has been fixed.

ios swift 2.1 - unable to send Patch request with body

I'm trying to write a http rest client for my webservice and i need to send some PATCH requestes with data in the body.
I'm using the JUST library for sending requests ( https://github.com/JustHTTP/Just )
My express application just doesn't see the request.
Here's some code (i'm testing in playground, and everything went fine with other kind of requests like put, post...)
headers = ["accept":"application/json","content-type":"application/json","authorization":"key"] //key is ok
var data = ["id":3, "quantity":6]
var r = Just.patch("http://api.marketcloud.it/v0/carts/1233", headers:headers, data:data) //1233 is a cart Id
print(r)
print(r.json)
The method Just.patch returns an HTTPResult Object.
this says 'OPTIONS http://api.marketcloud.it/v0/carts/13234 200'
Also this object should contain a json, but it's 'nil'.
On the server-side, my express applications doesn't receive the request (it just logs an 'OPTION', but nothing else).
Could this be a playground-related problem? Or a just-related one?
Thanks for any suggestion
I managed to contact the library's author via twitter and he fixed the bug and answered me in less than 24h!
Here's the new release of the library.

$.getJSON with Twitter rate_limit_api

I'm having trouble getting Twitter's rate_limit_status https://dev.twitter.com/docs/api/1/get/account/rate_limit_status to work correctly. I've used to curl and a web browser https://api.twitter.com/1/account/rate_limit_status.json to test it and it does returns a JSON object, but when I run the code below all I get is a 200 so I know I got the response successfully. It's not rated limited so even if I was over my limit it would still work. I've googled it and searched this forum but I can't seem to find why my specific code isn't working. As you can see I've put an alerts in the .getJSON function but neither goes off. I'm using the other Twitter APIs get Friends, get Followers successfully using basically the same code as below. I'm new to JQuery so I'm wondering if I'm missing something. Thanks in advance for any help!
function getRateLimit (){
var uri = "https://api.twitter.com/1/account/rate_limit_status.json";
$.getJSON(uri, function(data) {
alert("Alert before.");
console.log(data["reset_time"]);
console.log(data["remaining_hits"]);
alert("For testing purposes.");
});
}
The Same origin policy prevents that from working. Even if it would work, it would show the rate limit for each user and not for your application. (the rate limit status for the requester's IP address is returned)
You have to to get this data on server-side, everything else makes no sense.

backbone.js fetch error

I am facing a problem with getting a response in fetch function of backbone.js. I am using Backbone.js with rails.
$(document).ready(function(){
window.projectPerformanceReport.fetch({
success: function(e) {
$("#loading").hide();
window.questionListView = new QuestionListView;
window.questionListView.render();
window.headerView = new HeaderView;
window.headerView.render();
},
error: function() {
alert("Error");
}
});
});
There is already a URL set for the fetch method and it does make a request to online server which returns a JSON object. I checked by hitting that request independently in new tab and it worked fine. Also the JSON object returned is valid. But when i run this page i always get popup of 'Error'?
Any help would be great.
Thanks
Okay
I got what was the issue..... The thing that was happening was, The Java_Servlet which i was calling to get the JSON object was returning the data in text format instead of JSON... (But it was a valid JSON string)... and while calling the ajax method i had set the type as 'json' so it was failing.
Thanks to everyone who read my question and thought for a solution.
But one strange thing which i observed was, same code was working in production and not in my local machine??? Does anyone have some idea on why it could be behaving like that..???
Thanks :) Now i can sleep properly!!

Modify URL before loading page in firefox

I want to prefix URLs which match my patterns. When I open a new tab in Firefox and enter a matching URL the page should not be loaded normally, the URL should first be modified and then loading the page should start.
Is it possible to modify an URL through a Mozilla Firefox Addon before the page starts loading?
Browsing the HTTPS Everywhere add-on suggests the following steps:
Register an observer for the "http-on-modify-request" observer topic with nsIObserverService
Proceed if the subject of your observer notification is an instance of nsIHttpChannel and subject.URI.spec (the URL) matches your criteria
Create a new nsIStandardURL
Create a new nsIHttpChannel
Replace the old channel with the new. The code for doing this in HTTPS Everywhere is quite dense and probably much more than you need. I'd suggest starting with chrome/content/IOUtils.js.
Note that you should register a single "http-on-modify-request" observer for your entire application, which means you should put it in an XPCOM component (see HTTPS Everywhere for an example).
The following articles do not solve your problem directly, but they do contain a lot of sample code that you might find helpful:
https://developer.mozilla.org/en/Setting_HTTP_request_headers
https://developer.mozilla.org/en/XUL_School/Intercepting_Page_Loads
Thanks to Iwburk, I have been able to do this.
We can do this my overriding the nsiHttpChannel with a new one, doing this is slightly complicated but luckily the add-on https-everywhere implements this to force a https connection.
https-everywhere's source code is available here
Most of the code needed for this is in the files
IO Util.js
ChannelReplacement.js
We can work with the above files alone provided we have the basic variables like Cc,Ci set up and the function xpcom_generateQI defined.
var httpRequestObserver =
{
observe: function(subject, topic, data) {
if (topic == "http-on-modify-request") {
var httpChannel = subject.QueryInterface(Components.interfaces.nsIHttpChannel);
var requestURL = subject.URI.spec;
if(isToBeReplaced(requestURL)) {
var newURL = getURL(requestURL);
ChannelReplacement.runWhenPending(subject, function() {
var cr = new ChannelReplacement(subject, ch);
cr.replace(true,null);
cr.open();
});
}
}
},
get observerService() {
return Components.classes["#mozilla.org/observer-service;1"]
.getService(Components.interfaces.nsIObserverService);
},
register: function() {
this.observerService.addObserver(this, "http-on-modify-request", false);
},
unregister: function() {
this.observerService.removeObserver(this, "http-on-modify-request");
}
};
httpRequestObserver.register();
The code will replace the request not redirect.
While I have tested the above code well enough, I am not sure about its implementation. As far I can make out, it copies all the attributes of the requested channel and sets them to the channel to be overridden. After which somehow the output requested by original request is supplied using the new channel.
P.S. I had seen a SO post in which this approach was suggested.
You could listen for the page load event or maybe the DOMContentLoaded event instead. Or you can make an nsIURIContentListener but that's probably more complicated.
Is it possible to modify an URL through a Mozilla Firefox Addon before the page starts loading?
YES it is possible.
Use page-mod of the Addon-SDK by setting contentScriptWhen: "start"
Then after completely preventing the document from getting parsed you can either
fetch a different document from the same domain and inject it in the page.
after some document.URL processing do a location.replace() call
Here is an example of doing 1. https://stackoverflow.com/a/36097573/6085033

Twitter O-Auth Callback url

I am having a problem with Twitter's oauth authentication and using a callback url.
I am coding in php and using the sample code referenced by the twitter wiki, http://github.com/abraham/twitteroauth
I got that code, and tried a simple test and it worked nicely. However I want to programatically specify the callback url, and the example did not support that.
So I quickly modified the getRequestToken() method to take in a parameter and now it looks like this:
function getRequestToken($params = array()) {
$r = $this->oAuthRequest($this->requestTokenURL(), $params);
$token = $this->oAuthParseResponse($r);
$this->token = new OAuthConsumer($token['oauth_token'], $token['oauth_token_secret']);
return $token;
}
and my call looks like this
$tok = $to->getRequestToken(array('oauth_callback' => 'http://127.0.0.1/twitter_prompt/index.php'));
This is the only change I made, and the redirect works like a charm, however I am getting an error when I then try and use my newly granted access to try and make a call. I get a "Could not authenticate you" error. Also the application never actually gets added to the users authorized connections.
Now I read the specs and I thought all I had to do was specify the parameter when getting the request token. Could someone a little more seasoned in oauth and twitter possibly give me a hand? Thank You
I think this is fixed by twitter by now or you might have missed to provide a default callback url in your application settings, which is required for dynamic callback url to work as mentioned by others above.
Any case, I got this working by passing the oath_callback parameter while retrieving the request token. I am using twitter-async PHP library and had to make a small tweak to make the library pass the callback url.
If you are using twitter-async, the change is below:
modified getRequestToken and getAuthenticateURL functions to take callback url as parameter
public function getRequestToken($callback_url = null)
{
$params = empty($callback_url) ? null : array('oauth_callback'=>$callback_url);
$resp = $this->httpRequest('GET', $this->requestTokenUrl, $params);
return new EpiOAuthResponse($resp);
}
public function getAuthenticateUrl($callback_url = null)
{
$token = $this->getRequestToken($callback_url);
return $this->authenticateUrl . '?oauth_token=' . $token->oauth_token;
}
And pass the callback url from your PHP code.
$twitterObj->getAuthenticateUrl('http://localhost/twitter/confirm.php');
#Ian, twitter now allows 127.0.0.1 and has made some other recent changes.
#jtymann, check my answer here and see if it helps
Twitter oauth_callback parameter being ignored!
GL
jingles
even me to was getting 401 error.. but its resolved..
during registering your application to twitter you need to give callback url...
like http://localhost:8080.
i have done this using java...
so my code is: String CallbackURL="http://localhost:8080/tweetproj/index.jsp";
provider.retrieveRequestToken(consumer,CallbackURL);
where tweetproj is my project name
and index.jsp is just one jsp page...
Hope this may helps u...
After the user authorizes the application on twitter.com and they return to your callback URL you have to exchange the request token for an access token.
Twitter does not honor the oauth_callback parameter and will only use the one specified in the registered application settings.
It also doesn't allow for 127.0.0.1 or localhost names in that callback, so I've setup http://dev.twipler.com which is setup for 127.0.0.1 in DNS so you can safely use;
http://dev.twipler.com/twitter_prompt/index.php
