What this type of data looks like
Data for urban gas application materials and case review is sourced from enterprise business acceptance systems and archive management systems. It includes user application materials for services such as gas connection installation, ownership transfer, pipeline modification, and similar tasks (such as identification documents, site certificates, construction drawings), as well as review records and approval workflow data for corresponding services. The data exists as structured fields combined with attachments. Core fields include business ID, application time, applicant information, gas usage address, review status, and approval opinions. Business ID uses a string format, application time uses ISO standard timestamps, and review status uses fixed enumerated values. Application materials are generated in real time when work orders are submitted. Case data is updated along with audit process nodes. Archived data is synchronized to external interfaces once per natural day.
Constraints imposed on HTTP interfaces and external systems
The mixed structure of structured fields and attachments requires HTTP interfaces to support both structured parameter transmission in JSON format and binary file uploads. Fixed enumerated values and standard time formats for fields require interface parameters and return values to strictly match preset field formats and enumerated ranges, to avoid knowledge base import failures caused by incorrect field formats. Real-time generated application work orders require interfaces to support low-latency responses to meet the real-time demands of business submissions. Incremental synchronization requirements for archived cases require interfaces to provide parameters for pulling data within a specified time range, to facilitate regular synchronized updates. Application materials and case data contain sensitive personal information, so interfaces must use HTTPS encrypted transmission and be configured with identity authentication mechanisms.
Configuration Guidelines
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {custom service key} | Matches the interface authentication rules of the gas business system to ensure data transmission security |
| Maximum number of attachments per request | 3 | Adapts to the upper limit of supporting documents attached to a single gas application business |
| Request timeout period | 600 seconds | Covers the longest waiting duration for manual approval in the gas review process |
responseData | Map business fields to knowledge base indexes | Ensures extracted case and application material fields conform to FastGPT knowledge base import formats |
variables | Bind business ID and gas usage address as context variables | Helps the AI agent accurately match review case data for the corresponding business |
| Reordering | Calibrated based on actual testing | Adapts to long text content sorting requirements for gas case reviews |
Three Common Misconfigurations
- Symptom: 401 Unauthorized error is returned when calling the interface. Cause: The authentication parameter in the
Authorizationheader is not configured correctly, or the key does not match the authentication rules of the gas business system. - Symptom: The file b.md under dir1 in the API knowledge base is displayed in the upper-level folder. Cause: The file path field in the HTTP interface's returned
responseDatadoes not correctly carry directory hierarchy information, causing FastGPT to fail to recognize the directory structure. - Symptom: The AI agent shared as an API cannot retrieve corresponding knowledge base results, but matching works normally in the debug page. Cause: The
variablesparameter binding business information is not correctly passed during API calls, causing the AI agent to fail to associate case data for the corresponding business.
How to Confirm Successful Configuration
- Call the pre-configured HTTP interface, check that the returned
responseDatafield fully includes core information such as business ID, gas usage address, and review status, and that the attachment path field correctly marks the directory hierarchy. - Configure the
Authorizationheader to carry the correct authentication key and send a request, confirm that the return status code is 200 with no authentication-related errors. - Pass the
variablesparameter bound to a specific business ID in the API call request, verify that the AI agent can retrieve case review data for the corresponding business. - Upload the maximum allowed number of attachments per single request, confirm that the interface can receive the files normally and correctly import them into the knowledge base directory.
