Laravel：如何在重定向到获取方法路由URL时设置和获取自定义标头

Question

I am using Laravel 5.3 and trying to redirect to a url with custom headers. But some how I am not getting the header value in redirected page or we can say header value is not getting sent while redirecting.

I am using this code:

return redirect()->route('frontend.seller.signup')->header('referal_code', $referal_code);

and For fetch Header value I use below code but I not recieve header value

$referal_code = Request::header('referal_code');

Please let me know if I'm doing something wrong.

When you set headers for your response (even redirect is a response), headers are send to the client's browser.

The browser will process the response and redirect the page to the new URL and make a new request to server, so as you can figure out, your previous custom headers will not be available in the new request.

You can send any var using with() function to target url:

redirect()->route('frontend.seller.signup')->with('referral_code', $referral_code);

And get the variable in your target function using session:

$referral_code = session('referral_code');

By the way you can get the referrer in each request without setting any parameter in the referrer, if this is helpful in your case:

$referer = $request->headers->get('referer');
