What this category of data looks like
Non-ferrous metal smelting policy and regulatory basis data is primarily sourced from official public documents of the Ministry of Industry and Information Technology, the Ministry of Ecology and Environment, local industry and information departments, and the China Nonferrous Metals Industry Association. Data updates are adjusted according to the pace of policy releases. Immediate updates are made after major industry compliance policies are issued, and routine details are supplemented and revised quarterly. Each individual policy document includes fields such as policy number, issuing authority, effective date, applicable smelting categories (such as copper, aluminum, lead-zinc smelting), core clauses, penalty standards, and more. Field formats are unified and standardized. Some documents include industry-specific quantitative indicators and operational guidelines.
What constraints these characteristics impose on HTTP interfaces and external systems
Official policy data sources require interfaces to use legitimate authentication to prevent unauthorized scraping. The standardized fields and binding to specific smelting sub-categories require interface requests to pass clear smelting sub-type parameters, ensuring returned results accurately match business scenarios. The non-fixed update rhythm means external systems must regularly pull full policy packages or incremental update entries, and cannot rely on fixed hourly or daily automatic synchronization. Long document structures require interface returns to be simplified and extracted, to avoid redundant data occupying transmission bandwidth and context processing space.
How to configure settings
The following configurations apply to FastGPT v4.17.0:
| Configuration Item | Recommended Setting | Basis for This Setting |
|---|---|---|
Authorization | Bearer official policy data source secret | Identity authentication is required when connecting to official public policy interfaces, to comply with interface access specifications |
variables | {"sub_category": "copper smelting", "policy_type": "environmental compliance"} | Non-ferrous metal smelting policies are differentiated by sub-category and type. Passing precise parameters narrows the matching scope |
responseData | Only extract policy_code, publish_date, content_summary | Policy documents have redundant fields. Retaining only core fields reduces interface transmission load |
| Maximum number of returned entries per request | Top 10 | Individual policy documents have lengthy content. Too many returned entries will exceed context processing limits |
| Interface pull interval | 7200 seconds | Policy update frequency is relatively stable. This interval balances data timeliness and interface call costs |
Three common configuration errors
- When calling the interface to upload policy documents, an error is returned and file submission cannot be completed. The cause is incorrect configuration of interface file transfer parameters, which do not match the upload format requirements of the official policy data source.
- A single API key can only initiate one request per second, failing to meet concurrent query requirements. The cause is failure to configure multi-key load balancing, and failure to switch keys to implement concurrent calls.
- Other devices on the local area network return
net::ERR_INCOMPwhen accessing the interface, and pages fail to load. The cause is that the local IP bound to the interface has not been configured with local area network access permissions, resulting in interception of cross-device requests.
How to confirm correct configuration
- Initiate a test request, check whether the returned
responseDataincludes preset core fields such as policycode and publishdate. - Pass the specified non-ferrous metal smelting sub-category parameter, verify that returned results only match policy content for the corresponding category.
- After configuring multiple API keys, initiate concurrent requests, confirm that interface call rates meet expected requirements.
- Check local area network firewall settings, confirm that the local port is open, and no interception occurs for cross-device interface access.
