Create a Laravel Request object on the fly

Question

I'm handling data in one controller and want to pass it further into another controller to avoid duplicate code.

Is there a way to set up a Request object that is needed in the other controller's store -method? I've traced down the Request inheritance and came to Symfony's Request object which has a request property that is in fact a ParameterBag that holds a method add to add parameters with values to it.

I've tried the following but I'm getting null as result:

$myRequest = new Request();
$myRequest->request->add(['foo' => 'bar']);
var_dump($myRequest->foo);

I'm on Laravel 5.1 for this project.

You can use replace() :

$request = new \Illuminate\Http\Request();

$request->replace(['foo' => 'bar']);

dd($request->foo);

Alternatively, it would make more sense to create a Job for whatever is going on in your second controller and remove the ShouldQueue interface to make it run synchronously.

Hope this helps!

Creating a request object with $myRequest = new Request(); creates the object with method = 'GET' . You can check your request's method with $myRequest->getMethod() . As the request property holds data for POST requests you cannot use $myRequest->request->add() by default. First you have to set the request's method to POST:

$myRequest = new \Illuminate\Http\Request();
$myRequest->setMethod('POST');
$myRequest->request->add(['foo' => 'bar']);
dd($request->foo);

By the way using $myRequest->query->add() you can add data to a GET request.

To "avoid duplicate code" you need to abstract the common functionality into a dedicated class, give it a proper mnemonic name, write a set of unit tests around it, and then mock it in controllers when unittesting controllers.

but if you still need to make requests:

use Illuminate\Http\Request;

$request = new Request([
        'name'   => 'unit test',
        'number' => 123,
    ]);

and if you need the full functionality of the Request, you need to add some extra lines

$request
    ->setContainer(app())
    ->setRedirector(app(\Illuminate\Routing\Redirector::class))
    ->validateResolved();

您可以克隆现有请求并用新数据填充它：

$request = (clone request())->replace(['foo' => 'bar']);

Answer 5

You can add the request parameter on the fly using these methods.

Replace

replace function doc

If you are in controller then, pass Request object in paramter of the function like

  function createUser(Illuminate\Http\Request $request){
     $request->replace(array_merge(array("new_key1"=>"new_value1","new_key_n"=>"new_value_n"), $request->all()));
}

Merge function

merge function doc

function createUser(Illuminate\Http\Request $request){
     $request->merge(array("new_key1"=>"new_value1","new_key_n"=>"new_value_n"));
}

add function

 function createUser(Illuminate\Http\Request $request){
     $request->request->add(array_merge(array("new_key1"=>"new_value1","new_key_n"=>"new_value_n"), $request->all()));
}

Note:: in all function we are extending the request, mean previous parameter will remain there. You will be adding your own. You can replace them all.

You have to change

this

$myRequest = new Request();
$myRequest->request->add(['foo' => 'bar']);
var_dump($myRequest->foo);

to

$myRequest = new Request();
$myRequest->merge(['foo' => 'bar']);
echo $myRequest->input('foo');
