Struct actix_web::dev::ConnectionInfo

pub struct ConnectionInfo { /* fields omitted */ }

HTTP connection information.

ConnectionInfo implements FromRequest and can be extracted in handlers.

Examples

use actix_web::dev::ConnectionInfo;

async fn handler(conn: ConnectionInfo) -> impl Responder {
    match conn.host() {
        "actix.rs" => HttpResponse::Ok().body("Welcome!"),
        "admin.actix.rs" => HttpResponse::Ok().body("Admin portal."),
        _ => HttpResponse::NotFound().finish()
    }
}

Implementation Notes

Parses Forwarded header information according to RFC 7239 but does not try to interpret the values for each property. As such, the getter methods on ConnectionInfo return strings instead of IP addresses or other types to acknowledge that they may be obfuscated or unknown.

If the older, related headers are also present (eg. X-Forwarded-For), then Forwarded is preferred.

Implementations

impl ConnectionInfo

pub fn scheme(&self) -> &str

Scheme of the request.

Scheme is resolved through the following headers, in this order:

• Forwarded
• X-Forwarded-Proto
• Uri

pub fn host(&self) -> &str

Hostname of the request.

Hostname is resolved through the following headers, in this order:

• Forwarded
• X-Forwarded-Host
• Host
• Uri
• Server hostname

pub fn remote_addr(&self) -> Option<&str>

Remote address of the connection.

Get remote_addr address from socket address.

pub fn realip_remote_addr(&self) -> Option<&str>

Real IP (remote address) of client that initiated request.

The address is resolved through the following headers, in this order:

• Forwarded
• X-Forwarded-For
• remote_addr name of opened socket

Security

Do not use this function for security purposes, unless you can ensure the Forwarded and X-Forwarded-For headers cannot be spoofed by the client. If you want the client’s socket address explicitly, use HttpRequest::peer_addr() instead.
