I want to make a POST request to the remote server from jQuery. When I write code like this
$.ajax({
type: 'POST',
url: 'http://mysite:8080/orderService/order/send',
crossDomain: true,
data: JSON.stringify(orderSendRequest),
dataType: 'json',
success: function(responseData, textStatus, jqXHR) {
var value = responseData.someKey;
},
error: function (responseData, textStatus, errorThrown) {
alert('POST failed.');
}
});
Everything is ok, but I want ContextType to be application/json, and when I add this line to the code the request doesn't work and I have the following error:
XMLHttpRequest cannot load http://mysite:8080/orderService/order/send. Origin null is not allowed by Access-Control-Allow-Origin.
$.ajax({
type: 'POST',
url: 'http://mysite:8080/orderService/order/send',
crossDomain: true,
data: JSON.stringify(orderSendRequest),
dataType: 'json',
contentType : 'application/json; charset=utf-8',
success: function(responseData, textStatus, jqXHR) {
var value = responseData.someKey;
},
error: function (responseData, textStatus, errorThrown) {
alert('POST failed.');
}
});
I don't believe json supports crossDomain. Research using jsonp datatype instead.

I am using cookie authentication in ASP.NET Core Web API. When I am requesting for login from Postman, cookie is shown in Postman.
But when I am requesting it from ajax, the cookie does not get stored in the browser.
Here is my Ajax request - am I missing anything in Ajax?
$.ajax({
url: 'http://localhost:61610/api/auth/login',
method: 'POST',
xhrFields: {
'Access-Control-Allow-Credentials': true
},
data: JSON.stringify(para),
dataType: 'application/json',
contentType: 'application/json; charset=utf-8',
success: function (result, status, jqXHR) {
console.log(result);
alert(status);
},
error: function (jqXHR, textStatus, errorThrown) {
alert(textStatus);
}
});
you should try this
xhrFields: {
withCredentials: true
}
You need do some change in your ajax:
$.ajax({
url: 'http://localhost:61610/api/auth/login',
method: 'POST',
xhrFields: {
withCredentials: true
},
data: JSON.stringify(a),
dataType: 'application/json',
contentType: 'application/json; charset=utf-8',
success: function (result, status, jqXHR) {
console.log(result);
alert(status);
},
error: function (jqXHR, textStatus, errorThrown) {
alert(textStatus);
}
});
then you can send ajax with cookie
Here is a link with a more detailed explanation：

I am having a problem while using cross-origin ajax.
I know it's a common question but did not get any solution for it yet.
$.ajax({
type: "GET",
url: url,
data: {id:id},
dataType: "jsonp",
crossDomain: true,
contentType: "application/jsonp; charset=utf-8",
async: false,
success: fnsuccesscallbackk,
error: function(xhr, error){
alert(error);
},
jsonpCallback: fnsuccesscallback
});
function fnsuccesscallback(data){
alert(data)
}
…but getting undefined response in callback function.
Is there anything wrong what I am doing.
After a lots of RND finally i got the solution of this.
Ajax function:
$.ajax({
type:"GET",
url:'https://www.url.com/welcome/test_js',
data:{name:'xyz'},
crossDomain:true,
dataType: "jsonp",
jsonp: 'fnsuccesscallback',
success: function(data) {
alert(data.name)
}
});
In the Php function:
function test_js() {
echo $_GET['fnsuccesscallback'] . "(" . json_encode($_GET) . ")";
}
I am trying to fetch the data from php file by passing dynamic query string on ajax URL section.But while I changing datatype html to json. It is popping up error
jQuery(".nks_cc_trigger_element").click(function(){
var str = jQuery(this).attr("data-product_id");
jQuery.ajax({
url: "/ajax_product.php?q="+parseInt(str),
type: 'POST',
dataType: 'json',
success: function(result){
jQuery("#nks-content-1 > div").html(result);
console.log(result);
},
error: function(jqXHR,error, errorThrown) {
if(jqXHR.status&&jqXHR.status==400){
alert(jqXHR.responseText);
}else{
alert("Something went wrong");
alert(jqXHR.responseText);
}
}
}).done(function() {
});
>>PHP CODE
echo json_encode($data) ;
Use the data key/attribute and use the POST method, but don't pass the queries through the URL.
$(".nks_cc_trigger_element").click(function(){
var str = $(this).attr("data-product_id");
$.ajax({
url: "ajax_product.php",
type: 'POST',
dataType: 'json',
data: //json data,
success: function(result){
//success code
},
error: function(jqXHR, error, errorThrown) {
//error code
}
});
});
I have the following code which I wish to use for inserting a record into an entity of an ODATA service.
The post request throws a XMLHttpRequest cannot load Invalid HTTP status code 501.
Apparently GET request works fine. Can anyone suggest a way to find out the problem ? Does my WCF Service has a problem ?
var data = { application_id: 777 , user_id: 'test' };
var data = JSON.stringify(data);
$.ajax({
type: 'POST',
contentType: 'application/json; charset=utf-8',
datatype: 'json',
url: oDataURL + 'application_admins',
data: data,
beforeSend: function (XMLHttpRequest) {
XMLHttpRequest.setRequestHeader("Accept", "application/json");
},
success: function (data, textStatus, XmlHttpRequest) {
account = data.d;
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
}
});
I'm trying to get response header using AJAX, but it doesn't work. Apparently I did't do it right:
$.ajax({
type: 'GET',
url:'http://www.somesite.com/',
data: formData,
success: function(data, textStatus, XMLHttpRequest){
alert(XMLHttpRequest.getResponseHeader('some_header'));
}
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.getResponseHeader('some_header'));
}
});
I also try this one:
$.ajax({
type: "GET",
url: 'http://www.somesite.com/',
complete: function(xhr) {
alert(xhr.getAllResponseHeaders());
}
});
Any help?
You are missing a comma.
success: function(data, textStatus, XMLHttpRequest){
alert(XMLHttpRequest.getResponseHeader('some_header'));
}, // <-------------
