Struct Acceptable

pub struct Acceptable { /* private fields */ }

A guard that verifies that an Accept header is present and it contains a compatible MIME type.

An exception is that matching */* must be explicitly enabled because most browsers send this as part of their Accept header for almost every request.

Examples

use actix_web::{guard::Acceptable, web, HttpResponse};

web::resource("/images")
    .guard(Acceptable::new(mime::IMAGE_STAR))
    .default_service(web::to(|| async {
        HttpResponse::Ok().body("only called when images responses are acceptable")
    }));
