Laravel 5.4：当我有3个帖子页面使用相同的网址时，如何重定向回正确的页面？

Question

I want to keep the same url across 3 pages that have POST forms. When a form fails validation i'm doing \\Redirect::back()->withErrors() but if i'm on the second page it's returning to the 1st page. How can I return to the 2nd page instead of the 1st?

My routes are:

Route::post("/test",['as'=>'test','uses'=>'TestController@post']);
Route::get("/test",function(){ return View::make("pages.test"); });

My controller is:

class TestController extends Controller
{

function post(Request $request){
    if($request->has("test1")){
        return view('/pages/test2');
    }elseif($request->has("test2")){
        return \Redirect::back()->withErrors(["my error"]);
    }else{
        return "unknown test";
    }
}

}

My blade files are test.blade.php:

{{ Form::open(['action' => ['TestController@post']]) }}
Test1
{{ Form::hidden('test1', "test1")}}
{{ Form::submit('CONTINUE')}}
{{ Form::close() }}

test2.blade.php :

{{ Form::open(['action' => ['TestController@post']]) }}
test2
{{ Form::hidden('test2', "test2") }}
{{ Form::submit('CONTINUE')}}
{{ Form::close() }}

When return \\Redirect::back()->withErrors(["my error"]); executes i'm expecting to return to test2.blade.php but i'm returning to test.blade.php. How can I fix this?

You shouldn't be using return view() inside a post request.

This is an example of a request cycle from a shop:

GET  - show view 1 (shopping-cart)

POST - it's a form submmited from view 1
     - if it fails, it redirect to view 1
     - after doing the app logic, it redirects to view 2

GET  - show view 2 (payment-method)

POST - it's a form submmited from view 2
     - if it fails, redirect back will go to view 2
     - if it succeded, should redirect to view 3

GET  - show view 3 (order confirmation)

Your problem will disappear with this route structure
