Struct CsrfPlugin 

pub struct CsrfPlugin { /* private fields */ }

CSRF protection plugin.

Validates the Origin or Referer header on state-changing requests (POST, PATCH, DELETE, PUT) against a list of allowed origins. This is complementary to CORS: CORS controls which origins can read responses, while CSRF protection ensures that state-changing requests originate from trusted sources.

Implementations

impl CsrfPlugin

pub fn new(allowed_origins: Vec<String>) -> Self

Create a CSRF plugin with explicit allowed origins.

pub fn with_localhost(port: u16) -> Self

Convenience constructor for local development. Allows both localhost and 127.0.0.1 on the given port.

pub fn check( &self, method: &str, origin: Option<&str>, referer: Option<&str>, ) -> Result<(), PluginError>

Validate an incoming request.

For safe methods this always succeeds. For state-changing methods the Origin header is checked first; if absent the origin is derived from the Referer header. If neither header provides a trusted origin the request is rejected.

Trait Implementations

impl Plugin for CsrfPlugin

fn name(&self) -> &str

Unique name for this plugin.

fn on_request( &self, _method: &str, _path: &str, _auth: &AuthContext, ) -> Result<(), PluginError>

Called on every incoming request (middleware).

fn on_init(&self, _ctx: &PluginContext)

Called once when the plugin is registered.

fn routes(&self) -> Vec<PluginRoute>

Custom API routes this plugin handles.

fn before_insert( &self, _entity: &str, _data: &mut Value, _auth: &AuthContext, ) -> Result<(), PluginError>

Called before an entity insert. Return Err to reject.

fn after_insert( &self, _entity: &str, _id: &str, _data: &Value, _auth: &AuthContext, )

Called after a successful insert.

fn before_update( &self, _entity: &str, _id: &str, _data: &mut Value, _auth: &AuthContext, ) -> Result<(), PluginError>

Called before an entity update. Return Err to reject.

fn after_update( &self, _entity: &str, _id: &str, _data: &Value, _auth: &AuthContext, )

Called after a successful update.

fn before_delete( &self, _entity: &str, _id: &str, _auth: &AuthContext, ) -> Result<(), PluginError>

Called before an entity delete. Return Err to reject.

fn after_delete(&self, _entity: &str, _id: &str, _auth: &AuthContext)

Called after a successful delete.

fn on_request_with_meta( &self, method: &str, path: &str, auth: &AuthContext, _meta: &RequestMeta<'_>, ) -> Result<(), PluginError>

Richer variant of [on_request] that also receives per-request metadata (peer IP today; more fields may be added later). The default implementation delegates to on_request so existing plugins keep working without changes. Plugins that care about IP — notably rate limiting — override this hook.

fn on_session_create(&self, _user_id: &str, _token: &str)

Called when a new session is created.

fn entities(&self) -> Vec<ManifestEntity>

Additional manifest entities this plugin contributes.
