Auth Middleware

The Auth Middleware, defined in auth.go, is responsible for extracting authentication tokens from incoming requests. It supports multiple authentication methods to provide flexibility in how clients can authenticate.

Key Features​

  • Checks multiple sources for authentication tokens
  • Supports different authentication methods
  • Sets extracted token information in the request context

Token Extraction Process​

  1. Check the Authorization header
  2. If not found, check the X-API-Key header
  3. If still not found, check the access_token query parameter

Usage in Routes​

protected := r.Group("/api/v1")
protected.Use(middleware.AuthMiddleware())

This middleware sets the stage for token validation, which is handled by the Token Middleware.
