Sentry.io JavaScript tunnel on Laravel route?

The issue:
Because of issues with the JavaScript code loading I am trying to integrate sentry with the tunnel option. This would prevent the blocking, if a user has an ad-blocker enabled.
https://docs.sentry.io/platforms/javascript/troubleshooting/#using-the-tunnel-option
Now they provide an example code for this tunnel in their documentation:
<?php
// Change $host appropriately if you run your own Sentry instance.
$host = "sentry.io";
// Set $known_project_ids to an array with your Sentry project IDs which you
// want to accept through this proxy.
$known_project_ids = array( );
$envelope = stream_get_contents(STDIN);
$pieces = explode("\n", $envelope, 2);
$header = json_decode($pieces[0], true);
if (isset($header["dsn"])) {
$dsn = parse_url($header["dsn"]);
$project_id = intval(trim($dsn["path"], "/"));
if (in_array($project_id, $known_project_ids)) {
$options = array(
'http' => array(
'header' => "Content-type: application/x-sentry-envelope\r\n",
'method' => 'POST',
'content' => $envelope
)
);
echo file_get_contents(
"https://$host/api/$project_id/envelope/",
false,
stream_context_create($options));
}
}
In the app.php, the layout file of my project, I am calling the JavaScript Sentry like this:
<script src="{{ asset('/assets/js/app.js') }}" crossorigin="anonymous"></script>
My question:
What I don't understand is how to integrate this into the web.php as a route. So it gets called everytime an JavaScript error occured.

You should be able to define a route like this:
Route::post('/sentry-tunnel', function (Request $request) {
// Change $host appropriately if you run your own Sentry instance.
$host = "sentry.io";
// Set $known_project_ids to an array with your Sentry project IDs which you
// want to accept through this proxy.
$known_project_ids = [];
$envelope = $request->getContent();
$pieces = explode("\n", $envelope, 2);
$header = json_decode($pieces[0], true);
if (isset($header['dsn'])) {
$dsn = parse_url($header['dsn']);
$project_id = intval(trim($dsn['path'], '/'));
if (in_array($project_id, $known_project_ids)) {
return Http::withBody($envelope, "application/x-sentry-envelope")
->post("https://$host/api/$project_id/envelope/");
}
}
});
And then call the URL '/sentry-tunnel' from your JavaScript. Don't forget to add your project ID and credentials if necessary.

On click echo attribute

I am trying to create a gallery that uses PHP to go through asset folders and serve as sort of an album system. The code below retrieves files as albums :
<?php
include_once("../PhpScript/RetAlbInfo.php");
$files = array_slice(scandir('../Assets/Gallery/'), 2);
for($albflcnt = 0;$albflcnt<count($files);$albflcnt++){
echo "<div style='...'><div class='albm' style='...' onmousedown='gotoalbum();albnm();'></div><p style='...'>".$files[$albflcnt]."</p></div>";
}
?>
The problem is that I cannot find a way to get folder names from each <p> tag and append it to the url so it would show it's sub folder.

you can use glob() with GLOB_ONLYDIR option
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>
or
<?php
$dirs = array_filter(glob('*'), 'is_dir');
print_r( $dirs);
?>

You might be wanting a RecursiveDirectoryIterator? Not 100% sure. Here is a basic example. There are portions that may or may not be relevant. This basically builds a bread crumb system of sorts, but there may be parts you are looking for:
<?php
# Create some defines in the root of the website if not already done
# This is your url
define('SITE_URL','http://www.example.com');
# This is the root path
define('BASE_DIR',__DIR__);
# This is where everyour files are stored
define('MEDIA_DIR',__DIR__.'/media/');
/*
** #description This is just a link builder, there may be some functionality you could use here
** #param $path [string] Relative path
** #param $pathStr [string] Absolute path
** #param $append [string | empty] This is just append to whatever page processes this script
*/
function createLinks($path,$pathStr,$append = '/index.php')
{
# Used for the link
$url = SITE_URL.$append;
# Explodes relative path
$arr = array_filter(explode('/',$path));
# Loop through to create break crumb
foreach($arr as $dir) {
$pathStr .= '/'.$dir;
$new[] = '/'.$dir.'';
}
# Return final bread crumb
return implode('',$new);
}
# Decodes the path name, you should probably do a more secure encryption / decription method
function getPathFromRequest($path)
{
return base64_decode(urldecode($path));
}
# Set base absolute path
$core = MEDIA_DIR;
# Process the absolute path
if(!empty($_GET['goto'])) {
$base = str_replace('//','/',getPathFromRequest($_GET['goto']));
if(is_dir($base))
$base = $base.'/';
}
else
$base = $core;
# If is a directory, recurse and show the bread crumbs
if(is_dir($base)){
$skip = RecursiveDirectoryIterator::SKIP_DOTS;
$sFirst = RecursiveIteratorIterator::SELF_FIRST;
$dir = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($base,$skip),$sFirst);
# Loop through the file paths
foreach($dir as $file) {
$fname = $file->__toString();
if(is_file($fname)) {
$abs = str_replace($base,'',$fname);
$useType = (!empty($_GET['goto']))? $base : $core;
echo createLinks($abs,$useType).'<br />';
}
}
}
else {
# Redirect to file if is a file
if(is_file($base)) {
header('Location: '.SITE_URL.'/'.str_replace(BASE_DIR,'',$base));
exit;
}
}
Base view in the browser gives you something like (this is just from a directory I have):
/css/form.css
/css/styles.css
/images/bkg/bkg_white.png
/images/bkg/row_grad01.png
Then html source would look like:
/css/form.css<br />
/css/styles.css<br />
/images/bkg/bkg_white.png<br />
/images/bkg/row_grad01.png<br />
If you were to click the bkg in the 3rd or 4th link, it would display:
/bkg_white.png
/row_grad01.png
Clicking one of those would open the file in the browser. Anyway, you might be interested in some of this, all of it, or none of it! It's hard to guess with out seeing what you currently have vs what you are trying to achieve.

Magento "Headers already sent" after Upgrade

I've searched the web for days but can't find a solution. I upgraded Magento from 1.5 to 1.9 and everything works fine. Except the checkout. On the last step it gets stuck every single time on "submitting order information".
System log says the following (but a minute before the error occurs. In the stuck position I don't get any error)

Simultaneous connections on GTK Broadway backed

I'm new to GTK Broadway and I succeeded creating an instance of gedit running under it. I can access the interface using any browser and http://localhost:8080 but I can't open two different tabs on the same address. When I try to connect from another tab, the previous disconnects.
What I wish to do is to create a server running a GTK application on one side and serving this application for multiple users, they will be able to visualize the GUI and what's happening but only one user will be able to interact (I'm working on it).
Edit: I thought about a workaround where the server loads the page with the Websockets and the HTML5 Canvas then acts like a proxy and serves the same content to the clients, the proxy would then handle the incoming input from the clients (and manage the parallel connections). Is it technically possible?
Thanks in advance.

I found this on waybackmachine:

Server returning empty response on ajax call probably routing error

I have a simple search input that i want to POST data with an ajax call on click out using jquery on blur. The ajax call is the following code:
$(".ajax").blur(function(){
$.ajax({
type: "POST",
url : "adminController.php",
data : {
searchInput: $(this).val()
},
dataType : "json",
context : $("#searchResults"),
success: function(data)
{
$(this).text(data);
alert(data);
},
error: function (xhr,textStatus,err)
{
console.log("readyState: " + xhr.readyState);
console.log("responseText: "+ xhr.responseText);
console.log("status: " + xhr.status);
console.log("text status: " + textStatus);
console.log("error: " + err);
}
});
});
When the post call is made, i get a redirect (302 found) to my custom 404 page. However, the adminController.php is located correctly when i checked in chrome's console. If I remove the redirecting condition manually I get a 200 ok server response but with empty response. In my adminController.php I have the following code(code after the return in the constructor is not really necessary here): `
class adminController
{
private $postData;
private $errorMessage;
public function __construct()
{
$this->postData=array();
$this->errorMessage='';
session_start();
if(sessionClass::get('Username')== false || loginModel::checkAdmin()== false)
{
header('Location: /Costing/login');
exit();
}
if(($_POST)) {
//$this->handlePostData(); I entered the following
simple code to make sure my json return array is not the issue for my problems
$cars=array("Volvo","BMW","Toyota");
return json_encode($cars);
}
}
public function __destruct(){ }
public function displayPage()
{
$admin = new adminModel();
$nonAdminUsers = $admin->databaseInteract(sqlQueries::getNonAdmin());
$adminView = new adminView();
$adminView = $adminView->createAdminPage($nonAdminUsers);
echo $adminView;
}
private function handlePostData()
{
foreach($_POST as $key => $value)
{
if(!empty($value)) {
$sanitized_value = filter_var($value,FILTER_SANITIZE_FULL_SPECIAL_CHARS);
$sanitized_value = filter_var($sanitized_value,FILTER_SANITIZE_STRING);
$sanitized_value = filter_var($sanitized_value,FILTER_SANITIZE_MAGIC_QUOTES);
$this->postData[$key] = $sanitized_value;
}
else
$this->errorMessage.= $key.' is empty.';
}
if(!empty($this->postData))
{
$admin = new adminModel();
foreach ($this->postData as $key => $value)
{
if($key == 'Seller' || $key == 'Customer' || $key == 'Product')
{
$adminQuery = sqlQueries::searchOrders();
$tempArray['field']=$key;
$tempArray['value']=$value;
$result = $admin->databaseInteract($adminQuery,$tempArray);
$adminView = new adminView($result);
}
else if($key == 'nonAdmins')
{
$adminQuery = sqlQueries::promoteToAdmin();
$tempArray['Username']=$value;
$result = $admin->databaseInteract($adminQuery,$tempArray);
$adminView = new adminView();
$adminView->displayErrors($result);
}
else
{
$tempArray['value']=$value;
$adminQuery = sqlQueries::setConstants($key);
$result = $admin->databaseInteract($adminQuery, $tempArray);
$adminView = new adminView();
$adminView->displayErrors($result);
}
}
}
}
}`
what I am trying to achieve is instead of having a submit button, just post everything on blur and dump the results on the #searchResults div.
I think the problem has to do with my router class. The redirect in the first place on a post request did not seem healthy, so I will paste the code of my router and bootstrap files.
bootstrap.php:
<?php
/**
* #param $className
* bootstrap file for autoload function and router calling
*
*/
function my_autoloader($class) {
if (file_exists(realpath(__DIR__). DIRECTORY_SEPARATOR . $class . '.php'))
include realpath(__DIR__). DIRECTORY_SEPARATOR . $class . '.php';
else if (file_exists(realpath(__DIR__). '\\Classes\\' . $class . '.php'))
include realpath(__DIR__). '\\Classes\\' . $class . '.php';
else if (file_exists(realpath(__DIR__). '\\Classes\\Controller\\' . $class. '.php'))
include realpath(__DIR__). '\\Classes\\Controller\\' . $class. '.php';
else if (file_exists(realpath(__DIR__). '\\Classes\\Model\\' . $class. '.php'))
include realpath(__DIR__). '\\Classes\\Model\\' . $class. '.php';
else if (file_exists(realpath(__DIR__). '\\Classes\\View\\' . $class. '.php'))
include realpath(__DIR__). '\\Classes\\View\\' . $class. '.php';
else
{
$error = new errorController('classNotFound');
}
}
spl_autoload_register('my_autoloader');
$routes = new router();
$routes->add('/home', 'homeController');
$routes->add('/login', 'loginController');

$routes->add('/index.php', 'homeController');
$routes->add('/invoicing','invoiceController');
$routes->add('/admin','adminController');
$routes->add('/404','errorController');
$routes->submit();
and router.php
class router
{
private $routes = array();
private $method = array();
public function __construct(){}
public function __destruct(){}
/**

*/
public function add($uri, $method = null)
{
$this->routes[] =trim($uri,'/');
if ($method!= null)
$this->method[]= $method;
else
throw new exception();
}
/**

*/
public function submit()
{
$count=0;
if(isset($_GET['uri'])) {
$uri = $_GET['uri'];
}
else
$uri = '/home';
foreach( $this->routes as $key => $value)
{
if (preg_match("#^$value$#", $uri))

}
last but not least, my .htaccess
ReWriteEngine On
ReWriteRule ^public/ - [L,NC]
ReWriteBase /Costing/
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
RewriteRule ^(.+)$ index.php?uri=$1 [QSA,L]
Edit 1: I'm using Xampp and my domain is localhost/Costing/. I tried changing the url to Costing/admin so i got rid of the redirect. But still, unless I remove the dataType = "json" I get empty response back (if i remove json i get back the full html page with the scripts, aka adminView file). Using MVC architecture
Edit 2: I found a way around. Seems like i was right and the routing is causing the issue. So I created an ajaxHandler.php file and placed it outside the Costing directory and edited the ajax url like this: "http:// localhost/ajaxHandler.php". I get a valid response from this file but I can't really work with a file outside the root directory. So I need to change the htaccess. Any ideas are welcome

I found the solution myself, the problem was on htaccess. Basically the lines
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
Did not allow my urls to ask for files or directories, so anything ending on .php was forbidden. I had to create a folder and place my ajax handling file in there and add an exception like so:
ReWriteRule ^ajax/ - [L,NC]
Now the htaccess allows calls to this file and I can use it properly. I'm not sure this is secure though and I still have no idea why the url Costing/admin didn't work as marian correctly noted. If anyone finds out why it would be great

Aside from your bootstrap.php I do not see any actual executing php code (i.e. index.php).
For a single server side entry point, as it looks like you are working towards, you will want all requests to end up on the entry point with the full route request intact. From this entry point, you can then call the router which will then call the adminController class.
The order of operation then becomes:
Ajax request sent to /admin
Request is directed to the index.php
Index.php fires the bootstrap to load up the autoloader
Index.php calls the router with the incoming path
Router calls the actual AdminController class.
The empty response is likely because the server is only executing the adminController.php which does not appear to echo out anything (the class is never initialized in just that file).
