Call to undefined method Symfony\Component\HttpFoundation\StreamedResponse::header()

Question

Can't Download File as CSV

I'm trying to export some data as CSV & every time i try to export data i got this error - Call to undefined method Symfony\Component\HttpFoundation\StreamedResponse::header()

I have tried different possible ways but they aren't working

My Function (Controller File)

public function exportd(Request $request)
{
    $fileName = 'data.csv';
    $data = json_decode($request->data);

    $headers = array(
        "Content-type"        => "text/csv",
        "Content-Disposition" => "attachment; filename=$fileName",
        "Pragma"              => "no-cache",
        "Cache-Control"       => "must-revalidate, post-check=0, pre-check=0",
        "Expires"             => "0"
    );

    $columns = array('Name', 'Gender', 'experrience', 'location', 'Pref Location', 'Salary'
    ...
    );

    $callback = function() use($data, $columns) {
        $file = fopen('php://output', 'w');
        fputcsv($file, $columns);

        foreach ($data as $da) {
            $row['Name']  = $da->name;
            $row['Gender']  = $da->gender;
            $row['experrience']    = $task->experrience;
            $row['Pref Location']  = $task->pref_loc;
            $row['Salary']  = $task->salary;
            ...



                fputcsv($file, array($row['Name'], $row['Gender'],$row['experrience'], $row['location'], $row['Pref Location'], $row['Salary'] 
                ...
                   ));
            }

            fclose($file);
        };

    return Response()->stream($callback, 200, $headers);
}

My Middleware (AuthCheck)

public function handle(Request $request, Closure $next)
{

    if(!session()->has('LoggedUser') && ($request->path() !='auth/login' && $request->path() !='auth/register' )){
        return redirect('auth/login')->with('fail','You must be logged in');
    }

    if(session()->has('LoggedUser') && ($request->path() == 'auth/login' || $request->path() == 'auth/register' ) ){
        return back();
    }
    return $next($request)->header('Cache-Control','no-cache, no-store, max-age=0, must-revalidate')
                          ->header('Pragma','no-cache')
                          ->header('Expires','0');
}

I suppose you want to add the headers only when $next($request) is an instance of Illuminate\Http\Response (Not sure that the right class though) — Clément Baconnier

$next($request) is an instance of Symfony\Component\HttpFoundation\StreamedResponse in your scenario.

StreamedResponse does not support ->header(...). If you want to preserve your ->header(...) call, you must verify that the response is an instance of Illuminate\Http\Response


public function handle(Request $request, Closure $next)
{

    if(!session()->has('LoggedUser') && ($request->path() !='auth/login' && $request->path() !='auth/register' )){
        return redirect('auth/login')->with('fail','You must be logged in');
    }

    if(session()->has('LoggedUser') && ($request->path() == 'auth/login' || $request->path() == 'auth/register' ) ){
        return back();
    }

    $response = $next($request);

    if($response instanceof \Illuminate\Http\Response) {
        return $response->header('Cache-Control','no-cache, no-store, max-age=0, must-revalidate')
                          ->header('Pragma','no-cache')
                          ->header('Expires','0');
    }

    return $response;

}

An alternative worth to mention is that headers can be configured at your HTTP server level (nginx / Apache)

getting this error - This site can’t be reached ERR_INVALID_RESPONSE

ERR_INVALID_RESPONSE is usually a DNS issue. Are you certain this error come from the if condition ?

when i paste ur code i got this issue - ERR_INVALID_RESPONSE

The webpage at http://127.0.0.1:8000/exportd might be temporarily down or it may have moved permanently to a new web address.

What if you don't use the middleware ?

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class CorsMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
        $response = $next($request);
        $request->header('Access-Control-Allow-Headers', 'Origin, Content-Type, Content-Range, Content-Disposition, Content-Description, X-Auth-Token');
        $request->header('Access-Control-Allow-Origin', '*'); 
        return $response->prepare($request);
 
    }
}

Use above snip code. it has prepare() function in response object that you should add header on it and return it to the handle function.
