I am trying to use ajax in my laravel project. but it's showing me an error while dealing with ajax request like
POST http://localhost/hr_management/user/process-Requisition-Form 404 (Not Found)
can you please help me out?
Do you have a valid route entry for /hr_management/user/process-Requisition-Form in routes.php? If so, ensure that it uses post instead of get, for example:
Route::post('/hr_management/user/process-Requisition-Form', 'HomeController#processAjaxRequest');
If you're using a library like jQuery, for example, ensure you're specifying 'post'.
$.ajax({
url: '/hr_management/user/process-Requisition-Form',
method: 'post'
})
Make Ajax request in laravel 5.1
first register your route in routes.php
Route::post('/your/ajax/url','yourController#ajaxProcessFunction');
And make a ajax request with your favorite javascript library and don't forget to send X-CSRF-TOKEN in request header and valid request type.
Here is example for jQuery
$.ajax({
method:'post',
url:'{!!url('/') !!}/your/ajax/url',
data:yourdata
headers:{'X-CSRF-TOKEN':'{!! csrf_token() !!}'}
})

I pass the url to perform http request using $.ajax()
var url = document.location.hostname == "localhost" ? "http://localhost/mydomain.pl/admin/request": "/admin/request";
$.ajax({
type : "POST",
url : url
...
});
Everything is working fine, unless I change url for: http://www.mydomain.pl/admin/request. Why then it stop working? What is wrong?
I'm assuming you're trying to make an AJAX call from localhost to mydomain.pl.
By default, AJAX (or actually, XHR) cross-domain requests are blocked by the browser as a security measure.
There are ways to make that work - look into either JSONP or adding an appropriate CORS header, depending on your use case.
I am having a rather frustrating problem with the jquery post function that probably stems from not understanding how it works correctly.
I have a function that should post some form information to a php script that I wrote and that script then runs curl requests against an API to get around the cross-domain policy of javascript. It seems to work fine as long as it submits to "http" but when I send it to "https" the form never gets submitted.
I ran wireshark on my computer and it showed no traffic towards the destination ip until I made the url use http. I have basic auth on the server so I am passing the user and password through the url, but tested without that there and got the same results.
Here is the not working code:
$j.post("https://<api user>:<password>#<ip>:444/ProxyScript.php",
$j("#spoke_ticket").serialize(),
function(msg) {
log_status(msg);
fade_status();
$j(':input','#createtheticket')
.not(':button, :submit, :reset, :hidden')
.val('')
.removeAttr('checked')
.removeAttr('selected');
});
Here is the working function:
$j.post("http://<other ip>/ProxyScript.php",
$j("#spoke_ticket").serialize(),
function(msg) {
log_status(msg);
fade_status();
$j(':input','#createtheticket')
.not(':button, :submit, :reset, :hidden')
.val('')
.removeAttr('checked')
.removeAttr('selected');
});
Any ideas as to why the traffic is not being sent?
Let me know if I left out some key information or anything.
Thanks for the help
If you are doing the AJAX post from a http page to a https URL then the Cross-Domain policy kicks in because the protocol is also part of the origin specification, as it is described here. The browser will refuse to make the AJAX call, so that's why you're not seeing any traffic.
A solution is discussed here:
Ajax using https on an http page
So your best bet is the Access-Control-Allow-Origin header which should be supported on most modern browsers now.
So make your server add the following header to the responses:
Access-Control-Allow-Origin: https://www.mysite.com
If for some reason you cannot enforce this, then the only choice left would be JSONP.
Why not use a proxy to get over the cross-domain issue? It sounds more easy. An simple example is when i want to retrieve the danish administration national geo-data for counties,road names and so on (lucky for me, their data is in json or XML optional)
simplified proxy.php
<?
header('Content-type: application/json');
$url=$_GET['url'];
$html=file_get_contents($url);
echo $html;
?>
in ajax, get the lat/longs for a county borderline
var url= "proxy.php?url=https://geo.oiorest.dk/"+type+"/"+nr+"/graense.json";
$.ajax({
url: url,
dataType: 'json',
success: function (data) {
...
});
notice the https - the url could be, real example, https://geo.oiorest.dk/kommuner/0810/graense.json
I trying to do a DELETE, PUT, GET and POST a request with ajax and jquery.
The method POST works well by creating a new record, but I cannot make it work the other methods (PUT, DELETE and GET).
This is the code (it works fine, it creates the new record but it doesn't reach the "success" event):
var jsonExample = {"advertisement":{"title":"test"}};
$.ajax({
type: "POST",
url: "http://example.com/advertisements.json",
data:jsonExample,
success: function(response){
alert("test");
}
});
When I change the type "POST" to "DELETE" or "PUT" I have the follow error:
NetworkError: 404 Not Found
And when I change it to "GET" it throws the following message:
200 OK
But it don't any other responses. It should be something like this:
{"advertisement":{"created_at":"2012-04-17T13:20:17Z","from_age":null,"neighbourhood_id":null,"title":null,"date_to":null,"days":null,"promotion_id":null,"updated_at":"2012-04-17T13:20:17Z","date_from":null,"gender":null,"id":3,"display":null,"desc":null,"budget":null,"image":null,"to_age":null,"department_id":null,"town_id":null}}
The
Please note: my app is getting this info from a remote server, but I don't know if that has something to do with this problem. Because I've run it in Google Chrome and I've received the Access-Control-Allow-Origin message on the browser's console.
Any ideas?
You cannot make cross-domain AJAX requests using jQuery for security reasons. You may however be able to use jsonp providing that the URL you are requesting the data from is set up to handle jsonp requests.
This article should help you out alot more than I'm able to: http://www.fbloggs.com/2010/07/09/how-to-access-cross-domain-data-with-ajax-using-jsonp-jquery-and-php/
I want to get xml data from google server using it's API. so, i can't make any changes to response. So, How do I make this call that work for me:
$.ajax({
type: 'POST',
url: 'https://www.google.com/accounts/ClientLogin',
contentType: 'application/x-www-form-urlencoded',
data: { accountType : "HOSTED", Email : ""+Adminemail+"", Passwd : ""+adminpass+"", service : "cp"}, // cp for contact service..
success: function (response) {
alert(response); });
I want make some GET, PUT, DELETE call as well so, I don't want to use any function like $.getJSON();I want to make it possible through $.ajax() only.
I think only way to do this is use of server side scripting language.
Most browsers won't allow cross site scripting. (An ajax call that is not in your own domain).
So if you want to call such an url (https://www.google.com/accounts/ClientLogin), do it server side.
Cross domain posting is blocked by the browser. You could write your own browser. Since this is probably not an option, you could post to your own server and from there post to the other server. I think you can post data to another server using cUrl if you're using PHP.
There's a nice example here.
The third party must provide a jsonp api.
I am trying to make a RESTful webservice call using Extjs. Below is the code i am using:
Ext.Ajax.request({ url: incomingURL ,
method: 'POST',
params: {param1:p1, param2:p2},
success: function(responseObject){
var obj = Ext.decode(responseObject.responseText);
alert(obj);
},
failure: function(responseObject){
var obj = Ext.decode(responseObject.responseText);
alert(obj);
}
});
but it does not work, the request is sent using OPTIONS method instead of POST.
I also tried to do the same thing using below code but result is the same:
var conn = new Ext.data.Connection();
conn.request({
url: incomingURL,
method: 'POST',
params: {param1:p1, param2:p2},
success: function(responseObject)
{
Ext.Msg.alert('Status', 'success');
},
failure: function(responseObject)
{
Ext.Msg.alert('Status', 'Failure');
}
});
But when i tried to do the same thing using basic ajax call ( using the browser objects directly i.e. XMLHttpRequest() or ActiveXObject("Microsoft.XMLHTTP")) it works fine and i get the response as expected.
Can anyone please help me, as i am not able to understand what i am doing wrong with extjs ajax call?
You can't make a standard AJAX call between domains. The URL for Ext.Ajax.request should be a relative one (relative to the script's origin).
If you want to do cross-domain calls, use a ScriptTagProxy or such.
The problem is exactly because of the reason ob1 and Chuck Hinson described.
I have an RESTful service, wich is running on Tomcat.
And i made a static client(no deployed to Tomcat) using ExtJs with Json reader.
I just made an html page with ExtJs integrated consuming REST service like url: http://localhost:8080/service/invoices/
And all the time ExtJs was making OPTIONS request, not GET or POST even if i was setting them as being used methods. The problem is this security feature, because Client is not the part of same application and i am doing AJAX call between domains.
As soon as i put my client to my Web application and deployed to Tomcat and started using relative calls it started working.
if you don't want cross-domain request, please remove the website prefix 'http://website' from propery url of ajax proxy.
