关于请求头中x-api-idtoken与x-api-key是否随时间变更/过期的问询

Let’s break down whether these two headers change or expire over time:

1. x-api-idtoken (current value: null) #

• Right now, since it’s set to null, it’s likely indicating no user authentication token is being passed (maybe you’re accessing public fare data without logging in).
• If this parameter were to hold a valid ID token (like a JWT) once you log in, these tokens almost always have an expiration time (usually minutes to hours). Once expired, it would become invalid, and you’d need to obtain a new or refreshed token to continue authenticated requests.
• For now, though, the null value itself doesn’t "expire"—it just means no active auth token is present.

2. x-api-key (current value: l7xx944d175ea25f4b9c903a583ea82a1c4c) #

• This is typically a static API key tied to your application or developer account on the travel platform. These keys are designed to be long-lived in most cases.
• It won’t automatically change or expire over time unless:
  • The platform enforces a key rotation policy (requiring you to generate a new key periodically for security).
  • The key gets revoked (e.g., if it’s exposed publicly, or you violate the platform’s API terms of service).
• Important note: Keep this key private—sharing it could let others use your API quota or make unauthorized requests in your name.
