Struct www_authenticate::WwwAuthenticate

pub struct WwwAuthenticate(_);

WWW-Authenticate header, defined in RFC7235

The WWW-Authenticate header field indicates the authentication scheme(s) and parameters applicable to the target resource. This MUST be contained in HTTP responses whose status is 401.

ABNF

WWW-Authenticate = 1#challenge

Example values

• Basic realm="foo", charset="UTF-8"
• Digest realm="http-auth@example.org", qop="auth, auth-int", algorithm=MD5, nonce="7ypf/xlj9XXwfDPEoM4URrv/xwf94BcCAzFZH4GiTo0v", opaque="FQhe/qaU925kfnzjCev0ciny7QMkPqMAFRtzCUYo5tdS"

Examples

let auth = WwwAuthenticate::new(
    DigestChallenge {
        realm: Some("http-auth@example.org".into()),
        qop: Some(vec![Qop::Auth, Qop::AuthInt]),
        algorithm: Some(Algorithm::Sha256),
        nonce: Some("7ypf/xlj9XXwfDPEoM4URrv/xwf94BcCAzFZH4GiTo0v".into()),
        opaque: Some("FQhe/qaU925kfnzjCev0ciny7QMkPqMAFRtzCUYo5tdS"
                         .into()),
        domain: None,
        stale: None,
        userhash: None,
});
let mut headers = Headers::new();
headers.set(auth);

let auth = WwwAuthenticate::new(BasicChallenge{realm: "foo".into()});
let mut headers = Headers::new();
headers.set(auth);
let auth = headers.get::<WwwAuthenticate>().unwrap();
let basics = auth.get::<BasicChallenge>().unwrap();

Methods

impl WwwAuthenticate

fn new<C: Challenge>(c: C) -> Self

fn new_from_raw(scheme: String, raw: RawChallenge) -> Self

fn get<C: Challenge>(&self) -> Option<Vec<C>>

find challenges and convert them into C if found.

fn get_raw(&self, name: &str) -> Option<&[RawChallenge]>

find challenges and return it if found

fn set<C: Challenge>(&mut self, c: C) -> bool

fn append<C: Challenge>(&mut self, c: C)

append a challenge. This appends existing challenges of the same name.

fn append_raw(&mut self, scheme: String, raw: RawChallenge)

append a challenge. This appends existing challenges of the same name.

fn has<C: Challenge>(&self) -> bool

test if the challenge exists
