What the data for this category looks like
Relevant data for urban environmental sanitation and urban management law enforcement cases comes from urban management law enforcement platforms, urban operation grid platforms, video surveillance, and public complaint work orders. It updates daily. Daily business documents include inspection records, case filing approval forms, on-site photos, rectification orders, penalty decisions, and case closure reports. These documents cover core fields such as case number, violation type, responsible entity, and rectification progress. Some documents include multimedia attachments from on-site evidence collection.
What constraints these characteristics impose on deployment and upgrade
The data for this category comes from scattered sources, has diverse types, and updates daily. During deployment, configure multi-data source access and incremental synchronization logic to avoid excessive system resource usage from full-volume data pulls. Law enforcement documents include multimedia attachments. Adapt parsing and storage configurations for different formats. Law enforcement entities at different levels require isolated data access permissions. Configure layered permission rules during deployment. During upgrades, retain field mapping relationships for existing case data to avoid data synchronization errors caused by configuration changes.
How to Configure the Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 20–30 records per second | Adapt to concurrent pulls of case data from multiple data sources daily, avoid overloading database connections |
REDIS_URL | Local Redis instance address, cache validity period 3600 seconds | Cache frequently queried party building Q&A and case association data to reduce database access pressure |
STORAGE_S3_ENDPOINT | Local object storage endpoint address, maximum single file size 1000 MB | Store multimedia law enforcement documents such as inspection photos and penalty decisions, cover most on-site evidence collection scenarios |
FILE_TOKEN_KEY | Custom random string | Generate temporary access tokens for law enforcement documents to prevent unauthorized access to sensitive materials |
ROOT_KEY | Layered secret configured according to team permissions | Differentiate access ranges for Q&A data across different law enforcement levels, comply with confidentiality management requirements |
Three Common Configuration Errors
- Symptom: After local deployment, when uploading documents such as inspection photos and case filing approval forms, the system prompts file parsing failure or returns status code 413. Cause: The storage bucket limit corresponding to
STORAGE_S3_ENDPOINTis not configured correctly, or theFILE_TOKEN_KEYgeneration rule is incorrect, resulting in failed file upload verification. - Symptom: After upgrading to FastGPT v4.17.0, calling the party building Q&A interface returns a context overflow error. Cause: The concurrent connection configuration of
DB_MAX_LINKis not adjusted, causing the case data pulled from multiple data sources to exceed the Q&A context window limit. - Symptom: After cloud version deployment, WeChat scan code login fails to generate an initial login password, and administrators cannot access the backend configuration page. Cause: The initial permission secret corresponding to
ROOT_KEYis not configured, causing the permission verification logic of the login process to not trigger normally.
How to Verify Successful Configuration
- Log in to the FastGPT backend, enter the data source configuration page, and verify that the values of parameters such as
DB_MAX_LINK,REDIS_URL, andSTORAGE_S3_ENDPOINTmatch the local deployment environment. - Upload a typical law enforcement document such as an on-site photo or case closure report to confirm that the file can be parsed normally and associated with the party building Q&A knowledge base, with no parsing failure prompts.
- Log in with test accounts at different levels to verify that only law enforcement documents and party building Q&A content within the corresponding permission range can be accessed, confirming that the permission configuration takes effect.
- Manually trigger an incremental data synchronization task to check that the system can pull the latest case data according to the daily update schedule, with no synchronization blocking or data omission.
