Types

type BrowserConfig added in v0.5.0 

type BrowserConfig struct {
	// Issuer is the OIDC issuer/discovery base URL.
	Issuer string `json:"issuer" mapstructure:"issuer"`
	// ClientID is the OAuth2/OIDC client identifier registered with the provider.
	ClientID string `json:"client_id" mapstructure:"client-id"`
	// ClientSecret is the confidential client secret used in code exchange.
	ClientSecret string `json:"client_secret" mapstructure:"client-secret"`
	// Scopes controls requested OAuth2 scopes; defaults to openid/profile/email when omitted.
	Scopes []string `json:"scopes,omitzero" mapstructure:"scopes,omitzero"`
	// RedirectURI is the absolute callback URL registered with the OIDC provider.
	RedirectURI string `json:"redirect_uri" mapstructure:"redirect-uri"`

	// LoginPath is the local route that initiates login; defaults to /auth/login.
	LoginPath string `json:"login_path,omitzero" mapstructure:"login-path,omitzero"`

	// CookieDomain sets the optional cookie domain attribute for session cookies.
	CookieDomain string `json:"cookie_domain,omitzero" mapstructure:"cookie-domain,omitzero"`

}

BrowserConfig is a shared configuration contract for interactive, browser-based OIDC login flows.

Use BrowserConfig when your server application needs to:

  • redirect a human user to an OIDC provider login page,
  • exchange an authorization code for tokens server-side, and
  • keep the browser session in HTTP-only cookies.

Typical usage:

  • call Validate to fail fast on insecure or incomplete configuration,
  • call ToClientConfig to construct an oidc.Client, then
  • call ToOIDCConfig to configure this package's middleware Handler.

BrowserConfig is intentionally focused on browser sessions. For machine-to-machine APIs or bearer-token-only validation, prefer JWT validator configuration instead of browser login middleware.

Example (AuthenticatedConsoleDefaults) 
package main

import (
	"fmt"

	oidcmw "github.com/dioad/auth/http/middleware/oidc"
)

func main() {
	cfg := oidcmw.BrowserConfig{
		Issuer:       "https://auth.example.com/realms/connect",
		ClientID:     "connect-control-console",
		ClientSecret: "super-secret",
		RedirectURI:  "https://control.example.com/auth/callback",
		CookieSecure: true,
	}

	if err := cfg.Validate(); err != nil {
		fmt.Println("invalid config")
		return
	}

	clientCfg := cfg.ToClientConfig()
	mwCfg := cfg.ToOIDCConfig()

	fmt.Println(clientCfg.URL)
	fmt.Println(mwCfg.LoginPath)
	fmt.Println(mwCfg.Scopes)
	fmt.Println(mwCfg.TokenCookie.Secure)

}

Output:
https://auth.example.com/realms/connect
/auth/login
[openid profile email]
true
Example (CustomLoginPathAndScopes) 
package main

import (
	"fmt"

	oidcmw "github.com/dioad/auth/http/middleware/oidc"
)

func main() {
	cfg := oidcmw.BrowserConfig{
		Issuer:       "https://issuer.example",
		ClientID:     "admin-ui",
		ClientSecret: "secret",
		RedirectURI:  "https://admin.example/auth/callback",
		CookieSecure: true,
		LoginPath:    "/console/login",
		Scopes:       []string{"openid", "profile", "groups"},
	}

	mwCfg := cfg.ToOIDCConfig()
	fmt.Println(mwCfg.LoginPath)
	fmt.Println(mwCfg.Scopes)

}

Output:
/console/login
[openid profile groups]

func (BrowserConfig) ToClientConfig added in v0.5.0 

func (c BrowserConfig) ToClientConfig() authoidc.ClientConfig

ToClientConfig converts BrowserConfig into oidc.ClientConfig used to build an OIDC client for authorization-code token exchange.

func (BrowserConfig) ToOIDCConfig added in v0.5.0 

func (c BrowserConfig) ToOIDCConfig() OIDCConfig

ToOIDCConfig converts BrowserConfig into middleware OIDCConfig suitable for Handler.

Call Validate before using the converted configuration in production paths.

func (BrowserConfig) Validate added in v0.5.0 

func (c BrowserConfig) Validate() error

Validate checks that BrowserConfig is suitable for authenticated browser OIDC flows and enforces secure-cookie sessions.

Example (InsecureCookieRejected) 
package main

import (
	"fmt"

	oidcmw "github.com/dioad/auth/http/middleware/oidc"
)

func main() {
	cfg := oidcmw.BrowserConfig{
		Issuer:       "https://issuer.example",
		ClientID:     "admin-ui",
		ClientSecret: "secret",
		RedirectURI:  "https://admin.example/auth/callback",
		CookieSecure: false,
	}

	fmt.Println(cfg.Validate())

}

Output:
cookie-secure must be true for authenticated browser OIDC

type CookieConfig 

type CookieConfig struct {
	Name   string        `json:"name" mapstructure:"name"`
	Domain string        `json:"domain,omitzero" mapstructure:"domain,omitzero"`
	Secure bool          `json:"secure,omitzero" mapstructure:"secure,omitzero"`
	Path   string        `json:"path,omitzero" mapstructure:"path,omitzero"`
	MaxAge time.Duration `json:"max_age,omitzero" mapstructure:"max-age,omitzero"`
}

func (CookieConfig) Cookie 

func (c CookieConfig) Cookie(value string) *http.Cookie

func (CookieConfig) Delete 

func (c CookieConfig) Delete(w http.ResponseWriter)

func (CookieConfig) Set 

func (c CookieConfig) Set(w http.ResponseWriter, value string)

type Handler 

type Handler struct {
	Client *oidc.Client
	Config OIDCConfig
	// contains filtered or unexported fields
}

func NewHandler 

func NewHandler(client *oidc.Client, cfg OIDCConfig) *Handler

func (*Handler) AuthStart 

func (h *Handler) AuthStart() http.HandlerFunc

AuthStart initiates the OIDC authentication flow.

func (*Handler) Callback 

func (h *Handler) Callback() http.HandlerFunc

Callback handles the OIDC provider callback and sets cookies.

func (*Handler) CallbackPath added in v0.8.0 

func (h *Handler) CallbackPath() string

CallbackPath returns the URL path component of Config.RedirectURI that Callback should be registered at, or "" if RedirectURI is unset or unparseable.

func (*Handler) LoginPath added in v0.8.0 

func (h *Handler) LoginPath() string

LoginPath returns the path AuthStart should be registered at.

func (*Handler) Logout 

func (h *Handler) Logout() http.HandlerFunc

Logout clears all authentication cookies and redirects to root.

func (*Handler) LogoutPath added in v0.8.0 

func (h *Handler) LogoutPath() string

LogoutPath returns the path Logout should be registered at.

func (*Handler) WithBearerPassthrough added in v0.8.0 

func (h *Handler) WithBearerPassthrough(v bool) *Handler

WithBearerPassthrough configures whether Wrap forwards a request carrying a non-empty Authorization header to next without checking the OIDC session cookie, on the assumption a separately chained bearer-token validator (e.g. jwt.Handler) will authenticate that header itself. Defaults to false.

Only enable this when this Handler is explicitly chained ahead of another auth middleware that validates the Authorization header — never when it is used as a sole auth gate (e.g. via resolveOIDCHandler/WithServerAuth), since an unvalidated header would then let any request bypass authentication entirely.

func (*Handler) Wrap 

func (h *Handler) Wrap(next http.Handler) http.Handler

type OIDCConfig 

type OIDCConfig struct {
	Scopes      []string `json:"scopes,omitzero" mapstructure:"scopes,omitzero"`
	RedirectURI string   `json:"redirect_uri,omitzero" mapstructure:"redirect-uri,omitzero"`

	TokenCookie       CookieConfig `json:"token_cookie,omitzero" mapstructure:"token-cookie,omitzero"`
	StateCookie       CookieConfig `json:"state_cookie,omitzero" mapstructure:"state-cookie,omitzero"`

	RedirectCookie    CookieConfig `json:"redirect_cookie,omitzero" mapstructure:"redirect-cookie,omitzero"`
	IDTokenCookie     CookieConfig `json:"id_token_cookie,omitzero" mapstructure:"id-token-cookie,omitzero"`

	RefreshWindow time.Duration    `json:"refresh_window,omitzero" mapstructure:"refresh-window,omitzero"`
	Now           func() time.Time `json:"-" mapstructure:"-"`
	LoginPath     string           `json:"login_path,omitzero" mapstructure:"login-path,omitzero"`
	LogoutPath    string           `json:"logout_path,omitzero" mapstructure:"logout-path,omitzero"`

	// AllowInsecureCookies disables the default Secure attribute on session
	// cookies, allowing them to be sent over plain HTTP. Session cookies
	// carry live OAuth access and refresh tokens, so this must only be set
	// for local HTTP development — never in production. Mirrors
	// oidc.ValidatorConfig.AllowInsecureHMAC's explicit-opt-in shape.
	AllowInsecureCookies bool `json:"allow_insecure_cookies,omitzero" mapstructure:"allow-insecure-cookies,omitzero"`
