jQuery Ajax Post not posting data due to access control - javascript

I tried to post a form content to a remote hosted PHP page, this is my code:
$.ajax({
type: "POST",
url: "http://url/page.php",
data: formstring, // formstring=form.serialze();
dataType: "text",
success: function (data) { alert(data);},
error: function () {}
});
I started my PHP file with:
<?php
header('Access-Control-Allow-Origin: *');
print("hi");
die();
I see in Firebug only OPTIONS request:
Response Headers:

for that you should enable the cors in your ajax request
Example,
$.ajax({
url: "http://url/page.php",
type: "POST",
crossDomain: true,
data: formstring,
success: function (response) {
},
error: function (xhr, status) {
alert("error");
}
});

AJAX POST, why is data sent over URL?

I make an Ajax Post and get the following error:
414 Request-URI Too Large
Why is the data still sent over the URL and not only in the body?
In Chrome is see param1 data in the request URL, query string parameters and in request payload, how to remove it from the URL?
routes = JSON.stringify(routes);
$.ajax({
type: "POST",
url: "http://127.0.0.1:3000/s",
data: {
param1: routes
},
success: function(data) {
$('div.home-products').html(
data);
}
});
This is the full routes object after stringify:

view: grid

This is just a wild guess, but see if this helps:
url: window.location.href.replace(/\?.*$/, ''),
You definitely don't need to be passing along the get parameters that are in your href value, and this will strip them off. Perhaps the presence of any get parameters, even if it's just view-grid causes ajax to send your POST parameters as query parameters as well.

It turned out to be the missing contentType: "json", option.

Ajax Request not triggering success, Response 200

I am trying to request data by ajax from ripe.net, but the ajax request never triggers the success function, even through I get an http Response 200. My current code looks like this:
$.ajax({
headers: {
Accept : "application/json; charset=utf-8",
},
type: 'GET',
url: 'http://rest.db.ripe.net/search',
data: {
'source' : 'ripe',
'query-string': '172.217.16.67',
'type-filter': 'inetnum'
},
success: function(res) {
console.log(res);
}
});
(I changed the IP to google.com)
Currently I've tried the following things:
set no headers (I need to set a header with Accept : "application/json" because I need the JSON format
set the header in beforeSend
set dataType to json
set dataType to jsonp (throws an error)
set dataType to text
set contentType to "application/json; charset=utf-8"
add crossDomain: true
add processData: false
None of the above worked for me. Do you have an idea why the success function isn't called, or what i am doing wrong?
Edit:

Sending OAuth access token in Jquery Ajax request

Following documentation i put together this simple request. Every time i run this request i still get a 401 Authorization Required. I know the access token is fine because i use the same token using get to populate my models and it works fine it's only when i use post and place my token in the request headers.
Anyone else had this issue before?
jQuery.ajax( {
url: 'http://customer-server-2.dev/api/documents/add/.json',
type: 'POST',
data : {
guid : $('.guid-input').val(),
title : $('.title-input').val(),
payload : $('.payload-input').val()
},
beforeSend : function( xhr ) {
xhr.setRequestHeader( 'Authorization', 'BEARER ' + app.AccessToken );
},
success: function( response ) {
console.log(response);
},
error : function(error) {
console.log(error);
}
} );

JSON get result null

I'm developing an app using HTML5 with jQuery, and I am using Sync Framework for the synchronization and it consumes a service in the cloud (Windows Azure).
The problem is when I send the Request frame to the service:
$.ajax({
dataType: "json",
Accept: 'application / json',
url: serviceUri,
crossDomain: true,
success: function (json) {
console.log(" reponse :" + json);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
console.log("error :" + XMLHttpRequest.responseText);
}
});
The Request frame is:
GET http://157.56.8.203/DefaultScopeSyncService.svc/defaultscope /DownloadChanges?id=7AE7C771-0A98-4A5D-A046-430DDB0A7917 HTTP/1.1

The "data" object in the script is always null, but the reply frame has the correct data.
Can somebody help me?

You must write the call function with this code, the reponse data you can get with json.d.results if the response has more than one object if you will get single object than you reach them with json.d[0].
$.ajax({
dataType: "json",
Accept: 'application / json',
url: serviceUri,
crossDomain: true,
success: function (json) {
if (json.d.results == undefined)
{
// to do
}
else {
console.log(" response :" + json.d.results);
}
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
console.log("error :" + XMLHttpRequest.responseText);
}
});
Best Regards.

Cross domain requests doesn't allowing in ALL modern browsers and it is not good to use them. In any case if you would like to receive your data you need to user your server like proxy, so it will work like this:
You implement request from server (YOUR SERVER) to another server
You call request to YOUR server, not to another (cross domain server)
Other ways is hucking.
I.e. you can use this link (BUT I don't suggest it) http://james.padolsey.com/javascript/cross-domain-requests-with-jquery/

Ajax call to web service - success in method but forbids data access

I am trying to call a web service from an ajax jquery. It is successfully entering the success method but unfortunately a 403 error is being triggered and thus won't allow me to access the data.
This is my code:
try {
$.ajax({
type: "POST",
url: urlAddress,
data: dataa,
contentType: "text/xml; charset=utf-8",
success: function(Msg) {
// $("#Result").text(msg.d);
alert("ok");
alert("hi "+Msg.responseText + " How are you?");
},
error: function(request, status, error) {
alert("Error "+request.statusText.toString());
alert("ERROR");
}
});
}
catch (e)
{}
Msg.ResponseText comes back "undefined"
From Live Http Headers I get the following:
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip,deflate

Smells like urlAddress is not located on the same domain you're running that script.
That would breach the same origin policy and therefore, fail.
If I'm wrong here with that assumption, your're webservice might require a login (username+password) which you might missing to pass through .ajax().
