It depends on what code you have in those actions. Usually you return a Response object in an action middleware. Which basically means you will not execute the second action but go back through all the previous middleware.
What you can have in that middleware is something like this:
'middleware' => [
Middleware\SessionMiddleware::class,
Middleware\AuthMiddleware::class,
Action\PostAction::class
],
Both actions return $next(...) if there is $next. Here an example case:
test.global.php
<?php
return [
'dependencies' => [
'invokables' => [
App\ErrorHandler::class => App\ErrorHandler::class,
App\TestAction::class => App\TestAction::class,
App\TestAction2::class => App\TestAction2::class,
],
],
'routes' => [
[
'name' => 'test',
'path' => '/test',
'middleware' => [
App\TestAction::class,
App\TestAction2::class,
],
'allowed_methods' => ['POST'],
],
],
'middleware_pipeline' => [
[
'middleware' => App\ErrorHandler::class,
'priority' => PHP_INT_MAX, // always first
],
],
];
App\ErrorHandler.php
<?php
namespace App;
use Zend\Stratigility\MiddlewareInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\ResponseInterface;
class ErrorHandler implements MiddlewareInterface
{
public function __invoke(
ServerRequestInterface $request,
ResponseInterface $response,
callable $next = null
) {
file_put_contents('data/test.txt', __METHOD__ . PHP_EOL, FILE_APPEND);
set_error_handler(
function (
$errorNumber,
$errorString,
$errorFile = '',
$errorLine = ''
) {
file_put_contents(
'data/set_error_handler.txt',
implode(
', ',
[
$errorNumber,
$errorString,
$errorFile,
$errorLine
]
) . PHP_EOL, FILE_APPEND
);
}
);
register_shutdown_function(
function () {
$errorLast = error_get_last();
if ($errorLast) {
file_put_contents(
'data/register_shutdown_function.txt',
implode(', ', $errorLast) . PHP_EOL, FILE_APPEND
);
}
}
);
if ($next) {
$response = $next($request, $response);
}
return $response;
}
}
App\TextAction.php
<?php
namespace App;
use Zend\Stratigility\MiddlewareInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\ResponseInterface;
class TestAction implements MiddlewareInterface
{
public function __invoke(
ServerRequestInterface $request,
ResponseInterface $response,
callable $next = null
) {
file_put_contents('data/test.txt', __METHOD__ . PHP_EOL, FILE_APPEND);
$response = $response->withHeader('test', 'test');
if ($next) {
$response = $next($request, $response);
}
return $response;
}
}
App\TestAction2.php
<?php
namespace App;
use Zend\Stratigility\MiddlewareInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\ResponseInterface;
class TestAction2 implements MiddlewareInterface
{
public function __invoke(
ServerRequestInterface $request,
ResponseInterface $response,
callable $next = null
) {
file_put_contents('data/test.txt', __METHOD__ . PHP_EOL, FILE_APPEND);
$response = $response->withHeader('test2', 'test2');
if ($next) {
$response = $next($request, $response);
}
return $response;
}
}
Without any error you will get an data/text.txt
with content:
App\ErrorHandler::__invoke
App\TestAction::__invoke
App\TestAction2::__invoke
If you now force an fatal error in App\TestAction.php
the App\ErrorHandler.php
wont get invoked.
Expected:
App\ErrorHandler::__invoke
Got: empty
If you now force an fatal error in App\TestAction2.php
the App\ErrorHandler.php
will get invoked.
Expected:
App\ErrorHandler::__invoke
App\TestAction::__invoke
Got:
App\ErrorHandler::__invoke
App\TestAction::__invoke
_For some reason the register_shutdown_function
wont get executed at all in this cases oO?_
@sergu44o What version are you using? This issue is almost 2 years old.
This repository has been closed and moved to mezzio/mezzio; a new issue has been opened at https://github.com/mezzio/mezzio/issues/18.
Example: config
Im using a middleware _(priority PHP_INTMAX) to catch fatal error (
register_shutdown_function
). When im using one action only in the config and when i force an fatal error in that action the registered shutdown function gets called.If im using two actions as shown above then no registered shutdown function gets called. The middleware im using wont be invoked/loaded before the action.
