Data Structure for This Category
Data sources include the road transport administration system, the national public service platform for dynamic information of road transport vehicles, and the vehicle and practitioner database. The update frequency is daily. Daily documents include business license application materials, vehicle technical files, driver qualification materials, work safety management systems, and the original and duplicate copies of the road transport business license. Data fields include the unified social credit code of the operating entity, license number, vehicle license plate number, qualification certificate number, license effective and expiration dates, business scope filing items, and other related fields. All fields use standard government system formats, with no custom units added.
Constraints Imposed on HTTP Interfaces and External Systems
Since data sources come from multiple government systems, HTTP interfaces must adapt to a unified identity authentication logic. The Authorization header must carry the token format required by the government platform. The daily updated data source requires that interface call tasks be set with a daily scheduled trigger rule to avoid high-frequency calls triggering current limiting on government systems. Multiple types of business documents require the interface to support parsing both structured and unstructured data. variables must predefine standard field mapping rules for government documents. Data fields follow government standard formats, so the responseData returned by the interface must strictly match preset fields. Otherwise, ledger summary errors will occur. In addition, errors in license handling have serious consequences. A retry and alert mechanism must be configured for interface failures to avoid data synchronization interruptions affecting normal enterprise operations.
Configuration Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Carry the token issued by the government platform, valid for 7 days | Adapt to the identity authentication requirements of multiple government systems |
variables | Pre-map 12 standard government fields including operating entity name and license number | Match the fixed field structure of business documents |
responseData | Verify the completeness and format compliance of returned fields | Prevent ledger summary errors caused by missing fields |
| Retry Count | 3 times | Address request failures caused by temporary current limiting on government systems |
| Timeout Period | 30–60 seconds | Adapt to the interface response delay of government systems |
| Scheduled Trigger Frequency | Trigger at 2:00 daily | Match the daily update rhythm of the data source |
Three Common Errors
- Phenomenon: A database tool interface call returns a 400 status code with no response body. Cause: The
Authorizationheader is not correctly configured to carry the government system token, or the fields mapped byvariablesdo not match the database table structure. - Phenomenon: When embedding into a front-end page, the original component cannot be loaded, and only the API address can be accessed. Cause: FastGPT's API-only deployment mode is not enabled, or cross-domain access rules for the external system are not configured.
- Phenomenon: After uploading business documents, binary data cannot be obtained directly to initiate external HTTP requests. Cause: The binary data return switch is not enabled in the interface configuration, or the
responseDataverification rule filters binary stream fields.
How to Confirm Configuration Completion
- Use the API debugging tool of FastGPT v4.17.0 to initiate a test call, check whether the
Authorizationheader carries a valid token, and confirm the interface returns a 200 status code. - Check whether the fields returned by
responseDatainclude the preset license-related fields, with no missing or format errors. - Trigger the scheduled task to confirm that the interface automatically calls at the set time and completes data synchronization.
- Simulate an interface failure scenario to check whether the preset retry and alert mechanism is triggered.
