What the data for this category looks like
Advanced chemical materials policy and regulatory basis data is primarily sourced from official announcements and normative documents issued by the Ministry of Industry and Information Technology, the National Development and Reform Commission, and relevant industry regulatory authorities. Updates align with the official release of policies. Each individual policy document includes fields such as release document number, issuing authority, effective date, applicable advanced chemical material categories, and core regulatory and support clauses. There are no unified units for these fields. Some clauses involve quantitative indicators including production capacity and capacity utilization rate. Document lengths range from hundreds to thousands of words. Supplementary standard documents from some industry associations have minor format differences compared to official announcements.
What constraints these characteristics impose on HTTP interfaces and external systems
Policy data for advanced chemical materials is sourced from multiple dispersed locations, covering official APIs of multiple regulatory authorities. HTTP interfaces must adapt to different authentication rules. Independent Authorization parameters must be configured for each data source. Single policy document lengths vary significantly. Interfaces must support pagination to prevent single response bodies from exceeding reasonable transmission thresholds. There is no unified standard for field naming. After calling an interface, perform field mapping on responseData to adapt to field differences across data sources. Some policies include quantitative indicators. Interfaces must support filtering by applicable category, effective date, and other fields to ensure returned data matches business requirements.
How to configure the settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Exclusive token generated for the connected data source, or left blank for public data sources | Authentication requirements for policy APIs of different regulatory authorities vary; some public data sources do not require authentication |
variables | {"apply_category": "specialty fibers", "effective_date": "2024-01-01"} | Used to filter applicable categories and effective dates of advanced chemical material policies to narrow returned data scope |
responseData | Extract the policy list under the data field in the response body | Most official policy APIs wrap core data in the data field with outer metadata, which aligns with the interface configuration logic of FastGPT v4.17.0 |
| Timeout period | 10-30 seconds | Policy API response latency is affected by data source concurrency; this range covers most normal response scenarios |
| Pagination parameters | Concatenate in the format page=1&size=20 | Returning 20 policy data entries per page balances transmission efficiency and data integrity |
Three common mistakes
- Phenomenon: The interface returns status code 401, and the returned policy data is empty or displays a permission denied prompt. Cause: The
Authorizationparameter is not configured correctly, or the connected authentication token has expired and become invalid. - Phenomenon: The number of returned policy entries does not match expectations after calling the interface. Cause: The
sizevalue of the pagination parameter is not set correctly, or the correct filter conditions are not configured invariables. - Phenomenon: Unable to read cookie fields in the HTTP response. Cause: The cookie persistence option in the interface configuration is not enabled, or the corresponding cookie field is not specified in subsequent process nodes.
How to confirm the configuration is complete
- Send a test request, view the interface response body, and confirm that the fields extracted from
responseDatamatch the expected policy data structure. - Check whether the
Authorizationparameter matches the authentication requirements of the connected data source. Verify authentication validity by calling the test address provided in the official interface documentation. - Pass preset
variablesfilter conditions, and confirm that the returned policy data only includes entries that meet the applicable category and effective date requirements. - View the interface call logs, confirm that the response duration falls within the 10-30 second range, and there are no timeout error prompts.
