'Axios' The requested resource /gallery was not found on this server.

And you dont have any other routes at all, which are not listed here?

If not, can you then show the content of the store method?

actually i used /gallery in the axios thats why i only put gallery resource here. and I never use gallery resource anywhere. and controller i just echo "ok";

public function store(Request $request)
    {
    echo "ok";
    }

It should be (not that it whats causing the problem)

public function store(Request $request)
    {
    return "ok";
    }

But what I mean is do you have any routes that are not related to the gallery? My guess would be that you hit some other route instead of gallery.

Perhaps consider posting the content of web.php

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/logout', 'Auth\LoginController@logout');

Route::view('/form', 'student.login');
Route::view('/tform', 'Teacher.login');

//admin

Route::Resource('/teacherattendence', 'TeacherAttendenceController');

here is my web.php file

Route::post('/images', 'ImageController@store');

Route::delete('/images/delete', 'ImageController@destroy');

but if i use /images i have been created for that also shows 404 error

That is indeed strange. i dont see any issues in the web.php

If you open developer tools (f12) in chrome (under network tab) and then run the uploadfile method. Does it the hit the right url ?

it shows

Not Found
The requested resource /images was not found on this server.

If you click on it do you see something like this?

Nope it shows as following,

Request URL: http://127.0.0.1:8000/gallery
Request Method: POST
Status Code: 404 Not Found
Remote Address: 127.0.0.1:8000

did you set the csrf token for axios? check out https://laravel.com/docs/5.7/csrf#csrf-x-csrf-token

Yeah i did but i dont think it will be shown 404 error for csrf token
