Class ProxyAuthorization.Builder

java.lang.Object
org.apache.juneau.http.header.ProxyAuthorization.Builder
Enclosing class:
ProxyAuthorization
public static class ProxyAuthorization.Builder extends Object
Fluent builder for assembling an HTTP Proxy-Authorization credentials value.

Composes the scheme 1*SP ( token68 / #auth-param ) credentials form defined by RFC 7235 ยง4.4. The basic(String, String) and bearer(String) presets render the opaque token68 form; the digest() preset enables the typed Digest auth-params, which apply the correct quoting (quoted-string vs token). param(String, String) is a generic escape hatch so new params never require an API change. Setting a scheme preset or token(String) clears any previously-registered auth-params and vice versa, so a built value carries either a token68 or an auth-param list, never both.

Example:

String value = ProxyAuthorization.create() .digest() .username("Mufasa") .realm("http-auth@example.org") .uri("/dir/index.html") .qop("auth") .nc("00000001") .response("8ca523f5e9506fed4657c9700eebdbec") .build(); // => "Digest username=\"Mufasa\", realm=\"...\", uri=\"/dir/index.html\", qop=auth, nc=00000001, response=\"...\""

      Returns:
      This object.

    • username

      public ProxyAuthorization.Builder username(String value)
      Sets the username auth-param (rendered as a quoted-string).
      Parameters:
      value - The username. Must not be null.
      Returns:
      This object.
