In my Laravel 5.2 application, I'm trying to post some URLs via ajax in a loop but I get problems with both:
No supported encrypter found. The cipher and / or key length are invalid.
and
TokenMismatchException
Javascript code:
urls.each(function(url) {
var data = {
urls: url.value
};
$.ajax({
type: "POST",
url: "/ajax/checkUrl",
data: data,
headers: {'X-CSRF-TOKEN': '{!! csrf_token() !!}'},
success: function (data) {
var result = $.parseJSON(data);
console.log(result['msg']);
},
error: function (xhr, ajaxOptions, thrownError) {
console.log('Error: ' + thrownError);
}
});
});
routes.php
Route::group(['domain' => env('APP_URI')], function() {
Route::group(['middleware' => ['auth']], function () {
Route::post('ajax/checkUrl', 'AjaxController#checkUrl');
});
});
My AjaxController method is just following each URL with cURL, get some data and passing it back to the view.
Usually, I get the error
production.ERROR: exception 'RuntimeException' with message 'No supported encrypter found. The cipher and / or key length are invalid.' in C:\wamp\www\app\vendor\laravel\framework\src\Illuminate\Encryption\EncryptionServiceProvider.php:45
It works first but after ~50 ajax requests, some of them starts to fail with 500 (Internal Server Error).
I have tried with:
Excluded the ajax URL in VerifyCsrfToken Middleware.
Modified VerifyCsrfToken Middleware as some people at Stackoverflow suggested
Generated a new App key
In my config/app.php I have:
'key' => env('APP_KEY'),
'cipher' => 'AES-256-CBC',
My code works fine standalone outside the Laravel application so I don't know why I get these errors, even if I exclude the URL from CSRF protection?
These errors occurs on localhost. The production server generates 401 Unauthorized after ~100 ajax requests and sometimes logs me out.
Any suggestions why this occurs?

I've been trying to send ajax request to my laravel backend from my framework7 frontend using ajax.
$.ajax({
url: 'localhost:8000/server_file/grabtracks',
data: {task: "tracks"},
method: 'get',
async: false,
}).done(function(data) {
grabbedTracks = data;
});
Here is the code on my Laravel 5.4 routes
Route::get('/grabtracks', 'HomeController#grab_track');
And here is from my controller
public function grab_track()
{
$tracks = Track::all('id','title','location','price','track_file','track_img');
return response()->json($tracks);
}
I've disabled the CSRF tokens for the meantime, but i keep getting
Unauthorized error from my request
I'm at a loss, i've tried searching but only angularJS and laravel comes up.
It's probably your Controller has Auth middleware in your constructor remove the middleware and everything should work fine:
So you can remove this instructor or modify it to web auth:
public function __construct()
{
$this->middleware('auth');
}
I have a Laravel app that I recently uploaded on the server.
From this Question I found that I should add these to end of htaccess file (after all laravel configurations) in public directory:
<Limit GET POST PUT DELETE>
Allow from all
</Limit>
But server can not recognize requests that sent via PUT or DELETE methods and shows this error :
501
Not Implemented
The requested method is not implemented by the server.
Apache version is 2.2.31 and operating system is linux.
What is problem and does remain something that I should be add?
Update:
This is a part of my routes related to issue:
Route::group(['prefix' => 'post'], function () {
Route::resource('/category', 'CategoryController');
});
In the other hand I used a $.delete user defined function like this to send DELETE requests:
$.delete = function (url, data, callback, type) {
if ($.isFunction(data)) {
type = type || callback,
callback = data,
data = {}
}
return $.ajax({
url: url,
type: 'DELETE',
success: callback,
data: data,
dataType: type
});
}
And I used it to delete a category by it's ID:
$.delete('http://mysite.ir/post/category/20'+ , {}, function (res) {
// console.log(res);
}, 'json');
And destroy method that delete selected category:
public function destroy ($id, Request $request)
{
Category::destroy($id);
return ['success' => true, 'msg' => 'category removed.'];
}
It might be something you also need to change in your apache config file?
I have a fresh 5.3 installation and want to make api calls with postman. I also tried it with angular2 to make sure it's not a problem with postman.
In my routes/api.php I got a simple route:
Route::post('test', function(\App\Http\Requests\LoginRequest $request) {
return $request->all();
});
LoginRequest is checking if the fields email and password are there. If so, the output is as excepted. But when it's missing it redirects to /.
Do I have to add some information for form validation for ajax calls? I thought laravel would return a json error object when there is an ajax call.
Update:
I found out that I missed the Accept application/json header in Postman. With it it works finde. But is there a way to say that all api/* calls should be treated as a json call?
I created a new parent class for my Requests. It checks if the route belongs to the api group or not. I tried to add a Middleware to the group to add the header, but this trick failed.
class JsonRequest extends FormRequest
{
public function expectsJson()
{
return ($this->route()->getAction()['middleware'] == 'api');
}
}
You can response to ajax call like this
return response()->json(array('error' => $validator->getMessageBag()->toArray()), 400);
response status 400 indicates error and you will get in error section
error: function(jqXHR, textStatus, errorThrown){
var errResponse = JSON.parse(jqXHR.responseText);
if (errResponse.error) {
$.each(errResponse.error, function(index, value)
{
console.log(value);
});
}
}
I am using laravel 5 POST route in an AJAX call, I have defined it as,
Route::post('user/save-draft', ['as' => 'user/save-draft', 'uses' => 'UserController#saveDraft']);
I am also using Route::resource for the same controller above this save-draft route as,
Route::resource('user', 'UserController', ['except' => 'index']);
I am posting a form using AJAX with loading icon, what I am having strange here is that, data get save in the database, but I receive 404 error in the console like,
jquery.js:9664 POST http://www.example.com/user/save-draft 404 (Not Found)
So strange, and loading icon never get disappear which I do in ajax.done function.
While, my AJAX call is something like that,
var postData = {};
postData['frmSaveDraft'] = $frmSaveDraft.serialize();
startAjaxLoading()
$.ajax({
url: "http://www.example.com/user/save-draft",
type: "POST",
data: postData,
success: function (data) {
alert('success')
stopAjaxLoading();
}
});
UPDATE: Sorry, I missed url in AJAX here in above question,
Any thoughts ?
In controller method, I was returning response as,
echo json_encode(array('response' => true)); exit;
which was causing this issue may be exit keyword.
I have returned the response like,
return Response::json(array('response' => true));
which works great.
I'm trying to make a DELETE request within a Laravel app using ajax
I have a function to make the request - using the right verb - to a resource but keeps coming up method not allowed:
Here's my ajax request:
$.ajax({
type: 'DELETE',
url:'/user/58',
data: {
'_method': 'DELETE',
'id': id
},
dataType: 'json',
success: function (data) {
// do something with ajax data
if (data.result) {
return true;
}
return false;
},
error: function (xhr, ajaxOptions, thrownError) {
console.log('error...', xhr);
return false;
//error logging
},
complete: function () {
//afer ajax call is completed
}
});
id is supplied within a function and for the test is 58.
Watching the network panel in Chrome I can see it starts with the expected url of user/58 but then quickly gets shortened to user
I know that to get the resource route to pick up the request it needs to be user/58 and the method DELETE so it will go to the destroy method and because of this it is being routed to the Index method which expects a GET request hence the method not allowed.
Why is my request url being changed?
What is the correct approach to make a DELETE request in Laravel?
Thanks
Edit:
Here's my route:
Route::group( [ 'middleware' => [ 'auth' , 'admin' ] ] , function ()
{
Route::resource( 'user' , 'UserController' );
} );
The csrf token is being taken care of in the headers - fairly certain this isn't the cause of problem as I do not get an invalid token exception
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
Thanks
Two possible things that can happen here, I need to write this in a longer post than a comment so hopefully I got it right.
First thing that pops in my mind is an auth check that fails while doing the ajax request. At least I would redirect you back to the main resource if you wouldn't have enough rights.
However, my second guess is maybe even more likely. Have you thought of the X-CSRF-TOKEN that you need to send with an ajax request? See https://laravel.com/docs/5.2/routing#csrf-x-csrf-token
From the docs:
In addition to checking for the CSRF token as a POST parameter, the Laravel VerifyCsrfToken middleware will also check for the X-CSRF-TOKEN request header. You could, for example, store the token in a "meta" tag:
<meta name="csrf-token" content="{{ csrf_token() }}">
Once you have created the meta tag, you can instruct a library like jQuery to add the token to all request headers. This provides simple, convenient CSRF protection for your AJAX based applications:
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
