Error de CSRF de codeigniter: "La acción que ha solicitado no está permitida".

runtime-error csrf-protection

Question

habilité la opción csrf_protection en el archivo de configuración de codeigniter y usé la función form_open () para crear mis formularios. pero cuando envío el formulario, se produce este error:

The action you have requested is not allowed.

He hecho las respuestas como este tema (el que está más relacionado con mi pregunta): question

Answer 1

Simplemente incluya esto en su formulario y todo estará bien entonces.

<input type="hidden" name="<?php echo $this->security->get_csrf_token_name();?>" value="<?php echo $this->security->get_csrf_hash();?>">

Answer 2

A todos los que probaron todo lo que se sugirió aquí, y todavía tiene este problema.

Mi problema fue el tiempo de expiración de la cookie.

$config[''csrf_expire''] = 7200;

Después de que la cookie caduque y el usuario intente enviar un formulario, recibirá el error.

The action you have requested is not allowed.

Agregué un javascript simple a cada página, que soluciona el problema para el 99% de sus usuarios. (el 1% son usuarios que tienen JS desactivado en su navegador)

setInterval(function () {
  if(alert(''Your session has expired!'')){}
  else    window.location.reload(); 
}, 7200000);

Answer 3

Asegúrese de que su BASE_URL coincida con la URL que está viendo. Tengo dos alias (uno fue creado para oauth) y el proyecto funciona en ambos alias, pero CSRF fallará si BASE_URL no coincide con la URL en el navegador.

Answer 4

Cuando todo lo demás falló, noté que tenía mis variables de cookie establecidas, eliminar el nombre de la cookie, etc., resolví mi problema.

Answer 5

El problema resuelto por esta Solución:

establezca $config[''cookie_secure''] en el archivo de configuración en FALSE si está usando HTTP.

Answer 6

En config / config.php tengo

$config[''csrf_token_name''] = ''my.token.name'';

Pero cuando uso var_dump para $ _POST veo:

 ["my_token_name"]=> string(32) "f5d78f8c8bb1800d10af59df8c302515"

CI cambiar mi csrf_token_name (sic!)

Solución: cambié

$config[''csrf_token_name''] = ''my.token.name'';

a

$config[''csrf_token_name''] = ''my_token_name'';

Ahora funciona.

Answer 7

En la configuración si ha configurado el nombre de dominio de la cookie.

$config[''cookie_domain'']    = ''xyz.com'';

y navegas usando localhost . obtendrás el error

La acción que has solicitado no está permitida.

comprueba que si ayuda

Answer 8

He encontrado una solución a este problema que es bastante simple. Quité el div con la pantalla: ningún estilo que rodea la entrada csrf_protection. El div no es relevante ya que el tipo de entrada se establece en oculto. En CodeIginiterFolder / system / helpers / form_helper.php, cambié el siguiente contenido (alrededor de la línea 75):

if (is_array($hidden) AND count($hidden) > 0)
{
    $form .= sprintf("<div style=/"display:none/">%s</div>", form_hidden($hidden));
}

para el siguiente:

if (is_array($hidden) AND count($hidden) > 0)
{
    $form .= form_hidden($hidden);
}

Answer 9

La más fácil para mí fue incluir en la lista blanca el URI como se explica en la Guía del usuario de CodeIgniter ( here )

Los URI seleccionados se pueden incluir en la lista blanca de la protección csrf (por ejemplo, los puntos finales de la API que esperan contenido POSTed externo). Puede agregar estos URI editando el parámetro de configuración ''csrf_exclude_uris'':

$config[''csrf_exclude_uris''] = array(''api/person/add'');

Answer 10

URL EXCLUIR EN CONFIGURACIÓN DE ARCHIVO:

EJEMPLO:

$config[''csrf_exclude_uris''] = array(''main/registration'',''main/login'');

Answer 11

cambiar línea no 451

$config[''csrf_protection''] = true;

a

$config[''csrf_protection''] = false;

Debido a que csrf_protection está en desuso en CodeIgniter .

Answer 12

si permite true en $config[''csrf_protection''] = true; dentro del archivo de configuración y también está agregando un formulario de autoload que podemos usar.

Paso 1. dentro de la carpeta config.

$autoload[''helper''] = array(''url'', ''file'',''form'');

Paso 2.

$config[''csrf_protection''] = true; 

Paso 3. mientras se carga en la carpeta de vista

<?php echo form_open_multipart(''admin/file_upload''); ?>

De lo contrario, puede utilizar sólo

$config[''csrf_protection''] = false;
