What the Data for This Category Looks Like
The data sources for packaging and printing intelligent due diligence reports include enterprise industrial and commercial public information, printing production capacity equipment ledgers, raw material purchase records, downstream customer order fulfillment data, and industry printing qualification documents. Update rhythms vary across data types: raw material purchase and order data is updated weekly, industrial and commercial entity information is updated monthly, and qualification documents are updated quarterly. Each report has a fixed document structure, including four modules: enterprise entity information, production capacity parameters, compliance qualifications, and upstream and downstream cooperation details. Fields and units follow clear specifications: print format unit is millimeters (mm), annual production capacity unit is ten thousand color impressions, raw material purchase volume unit is tons, and printed product grammage unit is grams per square meter (gsm).
Constraints Imposed on HTTP Interfaces and External Systems
The multi-source, modular data characteristics of packaging and printing due diligence reports create clear constraints for HTTP interface and external system interactions. Fields with defined units require the interface to support unit verification, to prevent parameter parsing errors from cross-unit transmission. Data modules with different update frequencies require the interface to support configurable differentiated synchronization cycles, to adapt to weekly, monthly, and quarterly updated data sources. The fixed document structure requires the interface to return data mapped by module, without disrupting the original content order of the report. Large-volume equipment ledgers and order attachments require the interface to support large file transfers and extended parsing timeouts.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Packaging and printing due diligence reports often contain large-volume equipment ledgers and order attachments. The default timeout is insufficient to complete full parsing |
UPLOAD_FILE_MAX_SIZE | 2000 MB | A single packaging and printing production capacity ledger PDF may exceed 1 GB, requiring adaptation to large file upload requirements |
SYNC_INTERVAL_DAYS | 7, 30, 90 | Corresponds to the update rhythm of weekly order data updates, monthly industrial and commercial information updates, and quarterly qualification document updates |
BASE64_IMAGE_SUPPORT | Enabled | Packaging and printing due diligence reports often include printing proofs. When local files cannot be directly passed via links, base64 encoding support is required |
AI_PROXY_ENABLED | Configure as needed | Enable only when external systems cannot directly connect to FastGPT services. Supports direct integration with oneapi |
MULTI_FILE_UPLOAD_MAX_COUNT | 10 | Adapts to the batch upload requirement of multiple proof and ledger files attached to packaging and printing due diligence reports |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing.
Three Common Configuration Errors
- Scenario: Interface requests time out after 1 minute, returning status code 504. Cause: The
PARSE_FILE_TIMEOUT_SECONDSconfiguration was not adjusted. The default timeout, optimized for general documents, cannot handle large-volume packaging and printing due diligence reports. - Scenario: Only the first file is received during multi-file upload, with subsequent file parameters missing. Cause: The multi-file upload parameter format was not configured correctly. Independent content objects were not assigned to each file according to standard formats.
- Scenario: The interface returns a parsing failure when passing a base64-encoded printing proof. Cause: The
BASE64_IMAGE_SUPPORTconfiguration was not enabled. Only image links are supported, and base64-encoded content cannot be recognized.
How to Confirm Configurations Are Set Correctly
- Initiate an upload request for a single large-volume packaging and printing due diligence report. Check the parsing status returned by the interface to confirm the timeout configuration meets business requirements.
- Pass multiple printing proofs and ledger files. Check whether the interface receives all file parameters completely to confirm the multi-file upload configuration is correct.
- Pass a base64-encoded printing proof. Check whether the interface successfully parses the image content to confirm the base64 support configuration is enabled.
- View interface call logs. Verify that parameters such as timeout time and synchronization cycle match the configured items, with no abnormal errors.
