How can I handle NotFoundHttpException in Laravel 8? - laravel

I'm developing API in Laravel 8. I want to handle NotFoundHttpException to json response. But App\Exception\Handler updated in Laravel 8. By default render method does not exist. So I do not understand what I want to do. I have read in Laravel docs.

You can use a custom callback as per the documentation, App\Exceptions\Handler:
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
public function register()
{
$this->renderable(function (NotFoundHttpException $e, $request) {
return response()->json(...);
});
}
If you send the correct accept header with your request the exception handler will return a JSON response already though.

How can I use sub-directory?

I am new and install Laravel 6.x. And then I got a welcome(default) page.
But I didn't use the sub-directory in the website URL
I created the sub-directory like this below.
"www.test.com/test"
But that is not working.
/routes/web.php code source
It is working well.
Route::get('/', function () {
return view('./posts/test');
});
It is not working. So I got the "404" page.
Route::get('/test', function () {
return view('./posts/test');
});
How can I use sub-directory?
The problem was the Apache configuration:
<Directory "/home/....../public">
AllowOverride all
</Directory>

Laravel routes do not work

I am still new to PHP Laravel framework. The problem is that my Laravel routes do not work. Here is the simple code of my routes.php:
<?php
Route::get('/', function()
{
return View::make('hello'); //shows "Hello" page
});
Route::get('somepage', function()
{
return View::make('somepage'); // Apache server shows 404 error
});
I have configured my Apache param AllowOverride All and the mod_rewrite module is loaded. I have another installation of Laravel which works (throws 'NotFound' exception on undeclared route), but this one does not respond properly, on the same server. Where is the problem?
Make sure that your .htaccess file is setup correctly.
http://laravel.com/docs/installation#configuration
Please configure your Apache param AllowOverride All and ensure the mod_rewrite module is loaded.

Laravel Redirect All Requests To HTTPS

Our entire site is to be served over https. I have 'https' in each route. However, how do I redirect them to https if they attempt it over http?
Route::group(array('https'), function()
{
// all of our routes
}
Using App::before
You might be able to take advantage of the App::before() block in the app/filters.php file.
Change the block to include a simple check to see if the current request is secure, and if not, redirect it.
App::before(function($request)
{
if( ! Request::secure())
{
return Redirect::secure(Request::path());
}
});
Using Filters
Another option might be to create a filter like so. People generally store this also in app/filters.php.
Route::filter('force.ssl', function()
{
if( ! Request::secure())
{
return Redirect::secure(Request::path());
}
});
You can then enforce that new filter to any of your routes, route groups, or controllers like this.
Individual Route
Route::get('something', ['before' => 'force.ssl'], function()
{
return "This will be forced SSL";
});
Route Group
Route::group(['before' => 'force.ssl'], function()
{
// Routes here.
});
Controller
You'll need to do this in your controller's __construct() method.
public function __construct()
{
$this->beforeFilter('force.ssl');
}
Another answer might be to let your web server handle this. If you are using Apache, you can use the RedirectSSL feature to make sure all requests are going to the HTTPS version of your site, and if not redirect them. This will happen before Laravel even get's the request.
Apache RedirectSSL
If you're on NGINX, you can accomplish this by having two server blocks. One for normal HTTPS on port 80, and another for HTTPS on port 443. Then configure the normal server block to always redirect to ssl version.
server {
listen 80;
server_name mydomain.com;
rewrite ^ https://$server_name$request_uri? permanent;
}
server {
listen 443;
server_name mydomain.com;
ssl on;
# other server config stuff here.
}
I'd personally go with this option as PHP itself doesn't have to process anything. It's generally cheaper to process a check like this at the web server level.
For users using Laravel 4/5 and Elastic Beanstalk, forcing HTTPS is difficult using these methods because the isSecure() will return false. Further, using .htaccess redirects will result in a redirect loop for Chrome and delayed page load times in Firefox.
This set up is for
Laravel 5 and may work for Laravel 3 / 4
Application loaded onto Elastic Beanstalk running EC2 server instances
Route 53 used for DNS resolution
Cloudfront used for global CDN of all assets and enforcing HTTPS
I run aws on a Windows machine. Linux may vary slightly?
After hours of my own attempts, I managed to get all HTTP requests forwarded to HTTPS using the following steps:
Obtain an SSL certificate. Guides and providers are numerous and can be found via a Google search.
Upload the certificate to AWS using the aws console command. The command structure is:
aws iam upload-server-certificate --server-certificate-name CERTIFICATE_NAME --certificate-body "file://PATH_TO_CERTIFICATE.crt" --private-key "file://YOUR_PRIVATE_KEY.pem" --certificate-chain "file://YOUR_CERTIFICATE_CHAIN.ca-bundle" --path /cloudfront/
Create an Elastic Beanstalk application. Proceed through the setup process. Once the application is setup, go to Configuration -> Network Tier -> Load Balancing and click the gear icon.
Select Secure listener port as 443. Select Protocol as HTTPS. Select the CERTIFICATE_NAME from step 2 for SSL certificate ID. Save the configuration.
Go to your Console. Click EC2 Instances. Click Load Balancers. Click through the load balancers. Click Instances and scroll down to see the EC2 instances assigned to that load balancer. If the EC2 instance has the same name as your Application URL (or something close), take note of the DNS Name for the load balancer. It should be in the format awseb-e-...
Go back to your Console. Click CloudFront. Click Create Distribution. Select a Web distribution.
Set up the distribution. Set your Origin Domain Name to the load balancer DNS name you found in step 5. Set the Viewer Protocol Policy to Redirect HTTP to HTTPS. Set Forward Query Strings to Yes. Set Alternate Domain Names (CNAMEs) to the URL(s) you want to use for your application. Set SSL Certificate to the CERTIFICATE_NAME you uploaded in step 2. Create your distribution.
Click on your distribution name in CloudFront. Click Origins, select your origin, and click Edit. Ensure your Origin Protocol Policy is Match Viewer. Go back. Click Behaviors, select your origin, and click Edit. Change Forward Headers to Whitelist and add Host. Save.
Go to your Console. Click Route 53. Click Hosted Zones. Click Create Hosted Zone. Set up your domain name. Once set up, click Create Record Set. Enter your A record. Select Alias as Yes. Your Alias Target is your CloudFront distribution. Save the record.
Set up your nameservers for your domain to point to the Route 53 nameservers. Wait for everything to propagate, which could be a few hours. Go to your URL. You will be automatically redirected to HTTPS.
"But wait, my links don't go to HTTPS!?" You need to handle the X-Forwarded-Proto header that CloudFront will pass. For Laravel 4, follow this guide. For Laravel 5, run this:
php artisan make:middleware EB_SSL_Trust
And then add this to the EB_SSL_Trust file:
public function handle($request, Closure $next)
{
$request->setTrustedProxies( [ $request->getClientIp() ] );
return $next($request);
}
And add this to your App\Http\Kernel.php file:
protected $middleware = [
...
'App\Http\Middleware\EB_SSL_Trust',
...
];
Note: All your assets, such as CSS, JS or images, need to be sent over HTTPS. If you use Laravel to create these links, use secure_asset() to create the HTTPS URL in your View.
The use of filters has been deprecated in Laravel 5.1.*. This is a perfect job for a MiddleWare.
Create a Middleware and in the handle section put
public function handle($request, Closure $next)
{
if(! $request->secure()) {
return redirect()->secure($request->path());
}
return $next($request);
}
Then simply register your middleware in your Kernel.php and use it with your routes or controllers.
Using .htaccess Apache for laravel 4.2.X
Original File
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
# Redirect Trailing Slashes...
RewriteRule ^(.*)/$ /$1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
Edit File /public/.htaccess
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
# Redirect Trailing Slashes...
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
Combining previous answers and updating for Laravel 4.2:
Route::filter('secure', function () {
if (! Request::secure()) {
return Redirect::secure(
Request::path(),
in_array(Request::getMethod(), ['POST', 'PUT', 'DELETE']) ? 307 : 302
);
}
});
Route::when('*', 'secure');
If you want to redirect to the same URL but using https, you should use Request::getRequestUri() instead of Request::path():
App::before(function($request)
{
if( ! Request::secure())
{
return Redirect::secure(Request::getRequestUri());
}
});
This worked for me in Apache 2.4
I changed .htaccess in Laravel's root folder
From
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^(.*)$ public/$1 [L]
</IfModule>
To
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteRule ^(.*)$ public/$1 [L]
</IfModule>
If you have a problem, where for some reason Request::secure() returns false, even when the url is https, it could be because $_SERVER['HTTPS'] value doesn't exist.
This is a workaround:
App::before(function ($request){
// Force https
if(!Request::secure() && array_get($_SERVER, 'SERVER_PORT') != 443){
return Redirect::secure(Request::path());
}
});
I've had a problem with forcing ssl while doing POST request. It would always redirect to GET. This happens because Redirect::secure() is by default using a 302 redirect.
To make sure your POST request are redirected properly, use something like
return Redirect::secure("your/path/here", 307)
This will make sure your request will keep original request method after redirect occurs.
I don't understand about HTTP and HTTPS in detail, so I'm sorry if this answer isn't very good.
It's my understanding that there is an issue that even when client and (client specified) server are using HTTPS, Request::secure() can return false because your application may be running on a different server, which is possibly not receiving a https request.
I'm hosting my laravel app in heroku and it seems it does that. My guess is that the primary (client specified) server is a load balancer and when the request is forwarded, it arrives at the other server as a normal HTTP request.
When such forwarding can happen, you should not just check for Request::secure() to be true. I was instructed (by someone in #laravel # irc.freenode.com) to also check Request::server('HTTP_X_FORWARDED_PROTO') to see if it's equal to 'https'.
So if you intend to follow the other advice in here and perform a redirect in case of non-secure, try checking for this server parameter too.
For laravel 5.1 you should use given code in App\Http\Providers\RouteServiceProvider#boot
$router->filter('force.ssl', function () {
if ( ! request()->secure() ) {
return redirect()->secure(request()->path());
}
});
Now you can use this in routes file.
Route::group(['before' => 'force.ssl'], function () {
// Routes here
});
you can also add ['before' => 'force.ssl'] in $router->group() in
App\Http\Providers\RouteServiceProvider#map
If behind a proxy and Request::secure() is not working.
App::before( function( $request )
{
// set the current IP (REMOTE_ADDR) as a trusted proxy
Request::setTrustedProxies( [ $request->getClientIp() ] );
});
Combining previous answers to use constants and methods that are available in Laravel 4.2.
routes.php
Route::when('*', 'secure');
filters.php
use Illuminate\Http\Response as IlluminateResponse;
Route::filter('secure', function ()
{
if ( ! Request::secure() && Request::getPort() != 443)
{
return Redirect::secure(
Request::path(),
in_array(Request::getMethod(), ['POST', 'PUT', 'DELETE'])
? IlluminateResponse::HTTP_TEMPORARY_REDIRECT
: IlluminateResponse::HTTP_FOUND
);
}
});
If you have to use Laravel 4 itself to handle the redirecting (like me), I'd go for the following setup (explanation as comments in the code):
Route filter:
// app/filters.php
Route::filter('ssl.force', function()
{
if(App::environment('production') && !Request::secure())
{
// don't set a session cookie when redirecting to another scheme to
// avoid dropping the session when switching scheme
Config::set('session.driver', 'array');
// preserve query string while redirecting by using fullUrl()
// instead of Redirect::secure + Request::path()
$url = str_replace('http://', 'https://', Request::fullUrl());
return Redirect::to($url, 302, array(), true);
}
// secure cookies for https
Config::set('session.secure', Request::secure());
});
Then apply the filter as a before filter to your route or route group.
eg:
// app/routes.php
Route::group(array('before' => 'ssl.force'), function () {
// SSL routes
});

Serving static content from subdomain with codeigniter?

I’m in the process of splitting resources across domains. I’ve read a few different ways on how to handle this. From what I’ve read the correct way to handle is to use absolute paths versus relative. If this is true, how would I handle this as I push my local development live? The domains won’t match from local to live.
The base_url allows for a single domain only as far as I’ve read. Should I create an asset path helper and autoload that? Or, is there something I’m missing here?
http://www.example.com would operate normally.
http://images.example.com/assets would point to my asset folder that exists in the root.
Yeah, you're missing the part where the server configuration points stuff to certain places depending on the request that's made. This is before the request gets anywhere near codeigniter, so take a look at your server software manual and see what's up with that.
An example with Apache virtual hosts might be something like
#httpd.conf:
<VirtualHost *:80>
ServerName example.com
DocumentRoot /var/www/http
ErrorLog /var/log/httpd/error_log
TransferLog /var/log/httpd/access_log
</VirtualHost>
<VirtualHost *:80>
ServerName images.example.com
DocumentRoot /var/www/http/assets
ErrorLog /var/log/httpd/error_log
TransferLog /var/log/httpd/access_log
</VirtualHost>
In this example, a request to http://images.example.com/radical.gif would look in /var/www/assets/ for a gif called radical.
You could define a constant in config/constants.php for your assets url and use it:
define('ASSETS_URL', 'http://images.example.com/assets/');
Then of course you would go for it like that:
<img src="'.ASSETS_URL.'image1.png" />
After further research this is the way I solved my problem. Thanks to the Codeigniter forum for helping me get to this solution. Create a switch that checks which stage of development the site is in and set the base_url and asset_url config accordingly.
switch(ENVIRONMENT) //set in index.php
{
case 'development':
$config['base_url'] = 'http://localhost/';
$config['asset_url'] = 'http://localhost/assets/';
break;
case 'production':
$config['base_url'] = 'http://yoursite.com/';
$config['asset_url'] = 'http://assets.yoursite.com/';
break;
}
Then just extend the url_helper and create a function to get the asset_url
if ( ! function_exists('asset_url'))
{
function asset_url($uri = '')
{
$CI =& get_instance();
return $CI->config->item('asset_url') . ltrim($path, '/');
}
}

Is this a Sinatra config issue, or an Apache config issue?

I haven't decided if this is an Apache issue, or a Sinatra issue, basically, we have a bunch of little apps running on a single server, we deploy them with just built-in webrick instances and use apache to re-route those requests by subdomain to the right port. I am using gollum which is a sinatra app with a git persistence layer, but I am getting an unexpected app routing when it redirects (after edit action). I'm not sure if I can fix this by passing a startup option to Sinatra, or by configuring in the virtual host declaration for the app a rewrite rule. Please in your answer include which option you think is best and an example of how it might be accomplished.
Thanks,
# apache virtualhost declaration
<VirtualHost *:80>
ServerName wiki.domain.com
DocumentRoot "/var/www/html"
ProxyPass / http://localhost:3006
ProxyPassReverse / http://localhost:3006
</VirtualHost>
resolves with sinatra fine for GETs, eg
wiki.domain.com/Home
but fails on sinatra redirect
# expected
wiki.domain.com/Home
# actual
wiki.domain.com:3006/Home
and here is the Sinatra action (source: https://github.com/github/gollum/blob/master/lib/gollum/frontend/app.rb )
post '/edit/*' do
name = params[:splat].first
wiki = Gollum::Wiki.new(settings.gollum_path)
page = wiki.page(name)
format = params[:format].intern
name = params[:rename] if params[:rename]
wiki.update_page(page, name, format, params[:content], commit_message)
redirect "/#{CGI.escape(Gollum::Page.cname(name))}"
end
It’s a long shot, but perhaps the URLs in the ProxyPass directives need to have a trailing /? That’s how it is in the documentation, and I got some strange entries in error.log without them.
