What the data for this category looks like
The core data for this category is the full-lifecycle documentation of 12345 citizen hotline tickets. Daily documents include request registration forms, dispatch records, handling responses, follow-up visit records, delay applications, return explanations, and knowledge base entries. Data sources cover the 12345 hotline platform, contracting unit business systems, official knowledge bases, follow-up visit evaluation data, and local hotline management regulations. Update frequency is full daily synchronization. Each ticket is associated with multiple types of related documents. Core fields include request number, contracting unit, response content, follow-up visit evaluation, and other key information.
What constraints these characteristics impose during deployment and upgrade
The high-frequency daily ticket data requires that the database connection pool configured during deployment be adapted to high-concurrency read and write scenarios. This prevents connection exhaustion that causes ticket backlogs. Multi-source data synchronization requires configuring multi-data source adaptation rules. This ensures data consistency across request registration, dispatch, response, and other stages. The feature of multiple associated documents per ticket requires retaining the original field mapping logic during upgrades. This prevents ticket data loss from data structure changes. Additionally, ticket errors can lead to overdue deadlines, rejected tickets, or repeated public complaints. Deployment must configure exception alerting and retry mechanisms. This ensures the normal operation of the ticket closed-loop process.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 20–30 | Adapts to daily high-frequency ticket read and write requests, prevents connection pool exhaustion |
MONGODB_URI | Points to a dedicated ticket business MongoDB instance | Isolates ticket data from other business data, ensures data compliance |
REDIS_URL | Configures the address of a local cache instance | Caches frequently called dispatch rules and knowledge base content, reduces database load |
FILE_TOKEN_KEY | Bind to a validity period of 1800 seconds | Controls access validity of ticket attachments, prevents long-term abuse after token leakage |
ROOT_KEY | Generates a random key compliant with operation and maintenance specifications | Ensures access security of backend management interfaces, prevents unauthorized operations |
FE_DOMAIN | Set to the official domain name of the hotline inquiry frontend | Ensures callback notifications and page jump paths match business scenarios |
Three common mistakes
- Backend displays old version number after upgrade. For example, after deploying FastGPT v4.17.0, the interface still shows an old version number. The cause is failure to correctly replace frontend static resource files, or failure to restart backend services to load new version configuration files.
- Secondary development instance upgrade failure. For example, a ticket system developed on an older version fails to synchronize ticket data normally after upgrading to a new version. The cause is failure to retain original custom field mapping rules, leading to incompatibility between new code and old data structures.
- MongoDB connection error. For example, a security vulnerability-related error prompt appears when connecting to a MongoDB instance. The cause is using a MongoDB version with security risks, failing to update to a compliant version per operation and maintenance specifications, and failing to adjust the
DB_MAX_LINKparameter to adapt to high-frequency ticket requests.
How to confirm configurations are correct
- Log in to the FastGPT backend management interface. Check if the version number matches the deployed FastGPT v4.17.0. This confirms frontend resources and backend services have been updated correctly.
- Submit a test ticket. Check if data is correctly written to the specified MongoDB instance. This verifies that the
MONGODB_URIconfiguration is valid. - Generate an access link for a ticket attachment. Wait 1800 seconds, then attempt to access it. This confirms the token expiration logic is working correctly.
- Attempt to access the backend management interface with an unauthorized key. This confirms the security verification mechanism configured via
ROOT_KEYis operating normally.
