What this category of data looks like
Coal transportation and sales policy and regulatory basis data comes mainly from public documents of the National Energy Administration, provincial energy regulatory departments, and industry associations. It also comes from internal transportation and sales management specifications of coal transportation and sales enterprises. Data updates do not follow a fixed schedule. Sync updates when new policies release or internal regulations are revised. Most documents use structured official formats. They include fields such as policy document number, issuing authority, effective date, applicable transportation and sales links, and quantitative requirements. Units include tons, train trips, settlement cycles, and other relevant units.
What constraints these characteristics impose on HTTP interfaces and external systems
Coal transportation and sales policy data comes from multiple scattered sources. Connect multiple official and internal enterprise data sources via HTTP interfaces. Interfaces support filtering queries by region, transportation and sales link, and release time. Data updates follow no fixed cycle. Configure trigger-based synchronization or polling intervals calibrated to actual usage to avoid data lag. Structured policy document fields have clear definitions. Match interface return parameters to fields such as policy document number and effective date. This ensures downstream systems can directly extract key information. Single policy text lengths vary widely. Support returning full text or segmented content on demand via interfaces. This adapts to content calls for different scenarios.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
| Request timeout | 600 seconds | Coal transportation and sales policy documents are mostly long texts, interface return data volume is large, so sufficient response time must be reserved |
Authorization | Fill in the exclusive key allocated by the connected data source | Used for identity verification when connecting to official policy data sources |
variables | Pass regional codes and transportation and sales link type parameters | Adapt to policy queries for different provinces and cities and different transportation and sales links |
responseData | Extract policy document number, effective date, core clause fields | Match the structured data call requirements of downstream systems |
| Data source sync interval | 24 hours | Policy update frequency is low, daily sync balances timeliness and resource usage |
| Result return limit | Top 5 entries | Avoid returning too much data in a single call that exceeds the conversation context capacity |
Three Common Misconfigurations
- Calling an interface returns a 403 Forbidden status code, and policy data cannot be obtained. The cause is that the
Authorizationparameter is not configured correctly, or the key permission does not cover the target official data source scope. - Calling a configured external proxy interface returns a 404 status code, and the query cannot be triggered. The cause is that the interface address does not match the FastGPT external system configuration format correctly, resulting in route resolution failure.
- The policy data fields received by the external system are incomplete. The cause is that the fields to be extracted are not specified in the
responseDataparameter, and returning full raw text by default causes downstream parsing failures.
How to Confirm Proper Configuration
- Manually trigger an interface call, and check if the returned
responseDatafield includes preset key information such as policy document number and effective date. - View the external system's call logs, confirm that the
Authorizationparameter is correctly carried, and there are no identity verification failure records. - Adjust the filter conditions in the
variablesparameter, and verify whether the interface returned policy data meets the specified regional or transportation and sales link requirements. - Test consecutive interface calls, confirm that the request timeout configuration covers the response duration of most scenarios, and there are no continuous timeout errors.
