Basic Auth

HTTP Basic Authentication using a username/password validator function.

Usage

import "github.com/Pavan-Silva/go-zen/auth"

basicAuth := &auth.BasicAuth{
    Validate: func(username, password string) (*auth.User, error) {
        if username == "admin" && password == "secret" {
            return &auth.User{
                ID:       "1",
                Username: "admin",
                Authorities: auth.Authorities("ROLE_ADMIN"),
            }, nil
        }
        return nil, fmt.Errorf("invalid credentials")
    },
}

r.Use(auth.RequireAuth(basicAuth))

How It Works

• Reads the Authorization: Basic <base64> header
• Decodes and extracts username/password
• Calls the validator function
• Returns 401 Unauthorized on failure
• Stores the returned User in the context on success
