Laravel 5 / Lumen Request Header?

Question

So I am not really sure how to go about this I have tried a few things and I will list one below however what I am trying to do is store information sent in a http request in a PHP variable.

Here is a view from Chrome Postman of me sending the request I want ot send. Note "pubapi" is a "header".

I have been messing around with Lumen requests as you can see documented here ( http://lumen.laravel.com/docs/requests ) and have tried using the following below to possibly display them but its not working obviously.

echo Request::all();

I am putting this in my controller and I have ...

use Illuminate\Http\Request;

in my controller.

So how could I say store the header I am sending "pubapi" into a php variable in my controller?

EDIT

Not sure if this will help, however looking at the Laravel frameworks docs I see this http://laravel.com/api/5.0/Illuminate/Http/Request.html#method_header trying this throws the same error in my code. So for example I tried the following and reached the same error.

echo Request::header('pubapi');

Answer 1

You misunderstand the Laravel request object on two levels.

First, the error you are getting is because you were referencing the object instead of the Facade. Facades have a way of forwarding static method calls to non-static methods.

Second, you are sending the value as a header but are trying to access the request parameters. This will never give you what you want.

Here is a simple way to see an example of what you want by creating a test route like so:

Route::match(['get','post'], '/test', function (Illuminate\Http\Request $request) {
    dd($request->headers->all());
});

Post to this route and you will see your headers, one of which will be pubapi . Pay attention that the route method definition matches how you are submitting the request (ie GET or POST).

Let's apply this to the controller, ArticleController:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ArticleController extends Controller
{
    public function index(Request $request)
    {
        $pubapi = $request->header('pubapi'); // string
        $headers = $request->headers->all(); // array
        /*
          $pubapi === $headers['pubapi']
        */
    }
}

Answer 2

Try to change the Illuminate\\Http\\Request to Request .

- use Illuminate\Http\Request;
+ use Request;

Answer 3

Using

echo app('request')->header('pubapi');

Instead of

echo Request::header('pubapi');

Seemed to work perfect. Could someone provide additional explanation to why this worked and my original method didn't?

Answer 4

Actually you are calling it statically, that's why it is not getting appropriate Request class and throwing error, can do as follows

use Illuminate\Http\Request;

//inside your controller
class YourClass extends Controller{
   public function yourFunction(Request $request){
        //for getting all the request
        dd($request->all());

        //for getting header content
        dd($request->header('pubapi'));
   }
}

Answer 5

You can do it by request()->header('pubapi') also.

I prefer to use request() helper function than Request class its self. Because it can be used without use /import any class in the controller.
