What the data for this category looks like
Urban gas business processing data is sourced from the operator’s business management system, offline service window registration ledgers, and submission records from online processing portals. Data is synchronized in real time after a single business processing task is completed. Batch statistical data is updated daily. The document structure of a single business record includes item category, applicant identity identifier, processing node status, audit progress, and associated gas usage address information. Some fields such as processing duration use minutes or hours as units. Application volume uses "items" as the statistical unit. Fields have no unified fixed format and require flexible mapping based on business scenarios.
Constraints Imposed by These Characteristics on Deployment and Upgrade Processes
The multi-source access, real-time update, and high field association of urban gas business processing data create clear constraints for deployment and upgrade. Multi-source data access requires configuring protocol-compatible data synchronization nodes during deployment. This prevents incorrect guidance information caused by mismatched data formats across different systems. Real-time update requirements demand adjusting cache parameters. This ensures business node query delays meet user waiting expectations. The strong association of single records requires retaining original data mapping logic during upgrades. This avoids business process guidance failure from field misalignment. FastGPT v4.17.0 deployment requires additional adaptation for gas business batch data synchronization needs. This prevents data synchronization interruptions after upgrade.
Configuration Recommendations
| Configuration Item | Recommended Setup | Rationale |
|---|---|---|
MONGODB_URI | mongodb://username:password@host:27017/gas_service?authSource=admin | Urban gas business processing data is mostly unstructured business logs. MongoDB supports unstructured storage requirements. |
REDIS_URL | redis://:your_redis_password@host:6379/0 and configure maxmemory-policy allkeys-lru | Cache business processing node status and user sessions. This ensures real-time query delays meet business scenario requirements. |
FE_DOMAIN | https://your-gas-service-domain.com | Bind the access domain name of the business process guidance page. This ensures normal redirection of process links. |
FILE_TOKEN_KEY | Random 32-character string with no special characters | Validate uploads of business processing documents. This prevents unauthorized file access. |
DB_MAX_LINK | 20 | Adapt to daily concurrent volume of urban gas business. This avoids database connection exhaustion. |
STORAGE_S3_ENDPOINT | Endpoint address of local object storage | Store attachment materials for business processing, such as scanned copies of user identity documents. |
Three Common Misconfigurations
- Phenomenon: The model dropdown list in the workflow editor is empty, and pre-configured models cannot be selected. Cause:
ROOT_KEYpermissions were not correctly configured during deployment, or model cache was not synchronized and updated after version upgrade. - Phenomenon: A "file size exceeds limit" prompt pops up when uploading business processing attachments, returning a 413 status code. Cause: The upload file size limit inside the container was not adjusted. The default limit is 2MB, which cannot meet requirements for large files such as identity documents and pipeline drawings common in gas business.
- Phenomenon: A certificate error occurs when accessing the platform via
https://ip:3000, and the page fails to load. Cause: SSL certificates were not configured for local deployment. HTTPS was used directly to access an unencrypted HTTP port, leading the browser to block the insecure request.
How to Verify Successful Configuration
- Send a simulated POST request for urban gas business processing. Check that the interface returns a 200 status code and that data is successfully written to the specified storage medium.
- Enter the workflow editor. Check if the model dropdown list includes pre-configured model options, and confirm that permission configurations are effective.
- Upload business attachments of different sizes. Check upload progress and storage results, and confirm that the file size limit meets business requirements.
- Access the configured
FE_DOMAIN. Check that the business process guidance page loads normally, and that process redirection links have no abnormalities.
