What this category of data looks like
Railway operation service inquiry data comes from the official operation database, real-time ticket scheduling system, and standardized customer service knowledge base of China State Railway Group Co., Ltd. Ticket-related data is updated in real time alongside train scheduling and ticketing policies. Customer service response documents are updated regularly alongside new line openings and policy adjustments. Each data entry includes inquiry scenario classification, standardized response content, effective time range, and applicable train or station scope. Fields include: scenario classification (string), response content (rich text format), effective start date (YYYY-MM-DD format), applicable stations (list of strings). No additional mandatory statistical units are used; applicable scope is only marked per business scenario.
What constraints these characteristics impose on the "HTTP Interfaces and External Systems" link
Real-time railway ticket data requires interface response speeds to align with business scenarios, so HTTP request timeout settings must be controlled within a reasonable range. The scenario classification and applicable train or station fields require that interface requests carry corresponding parameters to accurately match data. Otherwise, irrelevant or incorrect responses will be returned. The regularly updated customer service knowledge base requires external systems to synchronize the latest documents periodically to avoid using outdated service inquiry content. Rich text format response content requires the interface return to support standard rich text parsing. Otherwise, formatting errors will occur. The authentication requirements of official railway interfaces are strict. Official issued keys must be used for authentication, otherwise normal calls cannot be made.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Authorization | Bearer Railway Operation Official API Key | Official railway interfaces require Bearer token authentication to ensure request legitimacy |
variables | JSON object containing departure station, arrival station, train number, and inquiry type | Matches the scenario classification and applicable scope fields of railway operation data to return targeted responses accurately |
responseData | Only return response content, applicable scope, and update time fields | Filters redundant data to improve interface response speed and align with the structure requirements of railway data |
| Single request timeout | 8–12 seconds | Aligns with the response requirements of real-time railway ticket data to avoid excessive timeout impacting business |
| Retry count | 2 times | Addresses occasional network fluctuations of railway interfaces and improves request success rate |
| Single response content limit | 5000 characters | Aligns with reasonable front-end display length requirements to avoid content overflow |
Three common configuration mistakes
- Symptom: The interface returns a 401 Unauthorized status code. Cause: The
Authorizationparameter is not configured correctly, or an expired official API key is used. - Symptom: No knowledge base-associated response content is returned after sending a conversation request. Cause: Scenario-related parameters are not included in
variables, making it impossible to match railway operation inquiry scenarios and corresponding knowledge base data. - Symptom: Formatting errors appear in the response content returned by the interface. Cause: The correct response format is not configured, or the rich text field requirements of railway data are not adapted.
How to confirm the configuration is correct
- Call the test interface, pass valid authentication parameters, and check that the returned HTTP status code is 200 to confirm authentication is successful.
- Pass preset inquiry scenario parameters, and verify that the returned response content matches the official public service guidelines of the railway operator.
- Check the interface response time to confirm it meets the response requirements of the business scenario with no obvious timeout issues.
- Check the structure of the returned fields to confirm that core fields such as response content and applicable scope are included, and the format matches expectations.
