Summary

OAuth Proxy Service - OAuth 2.0 Proxy Service

Description:

This service provides proxy context management functionality for OAuth 2.0 authorization flows,
primarily used to prevent CSRF (Cross-Site Request Forgery) attacks.

Main Features:

  1. create_proxy_context(): Create proxy context

    • Generate unique context_id (UUID)
    • Store user session information in Redis cache
    • Set 5-minute expiration time
    • Return context_id for OAuth authorization URL

  2. use_proxy_context(): Validate proxy context

    • Retrieve and delete stored context data from Redis
    • Validate context_id validity and expiration time
    • Return user session information for subsequent processing

Security Features:

  • Use Redis distributed cache for session state storage
  • Implement one-time use mechanism (getdel operation)
  • Timestamp-based expiration validation
  • Protection against replay attacks and CSRF attacks

Use Cases:

  • OAuth 2.0 authorisation code flow
  • OAuth callback processing requiring state validation
