What the data for this category looks like
The data sources for shipping port financing daily reports are primarily port operation management systems, international shipping freight forwarding platforms, and shipping financing filing databases of local financial regulatory authorities. Data is updated once daily, covering all shipping financing transactions from the previous full calendar day. The document uses a structured table format, arranged by port, route, and financing entity. Core fields include port UNLOCODE, route name, vessel type, cargo category, single voyage financing amount, financing term, and loan disbursement date. Amount units are Renminbi or US dollars, and term units are calendar days or calendar months.
What constraints these characteristics impose on HTTP interfaces and external systems
Data sources are scattered and include multiple heterogeneous systems. HTTP interfaces must be used to connect at least 2-3 external data sources, so multi-source data aggregation logic must be configured. The daily update rhythm requires interface polling frequency to match the data source update cycle, to avoid excessive calls or delayed access to the latest data. The structured field format requires interface returned data to strictly match preset field names and units, otherwise subsequent parsing will fail. Cross-currency financing amounts require additional exchange rate conversion, which increases the complexity of interface data verification and cleaning.
How to set configurations
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
external_data_source_type | structured_api | Shipping port financing daily reports use standardized structured data, which is compatible with API pull and parsing mode |
api_polling_interval | 86400 seconds | Matches the daily update rhythm of data sources, avoids frequent calls that consume resources |
response_field_mapping | {"Port Code": "unlocode", "Financing Limit": "amount", "Loan Date": "loan_date"} | Matches the native field names returned by external data sources, ensures no deviation during data parsing |
api_timeout | 30 seconds | Covers the normal response duration of most shipping data interfaces, avoids unnecessary timeouts triggered by network fluctuations |
currency_conversion_switch | enabled | Adapts to the unified display requirement of multi-currency financing amounts, ensures data consistency |
max_retries | 3 times | Addresses temporary interface fluctuations, reduces the probability of single call failure |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- The platform knowledge base test results do not match the financing daily report data returned by API calls. The cause is incorrect configuration of
response_field_mapping, which causes the raw data pulled via the API to not be mapped to the standard fields used for knowledge base indexing. - The API call returns a
400 Bad Requesterror. The cause is passing field names that do not exist in the external data source, which violates the interface parameter verification rules. - Interface calls frequently trigger timeout errors. The cause is that
api_timeoutis set too short, failing to cover the normal response delay of shipping data interfaces.
How to confirm the configuration is complete
- Call the configured HTTP interface, check whether the returned JSON structure corresponds one-to-one with the fields preset in
response_field_mapping. - Check the daily pull task logs, confirm that the pull time matches the data source update time, and the pull frequency complies with the
api_polling_intervalsetting. - Simulate scenarios where the interface returns missing fields or abnormal currency units, check whether the system triggers the
max_retriesretry logic or the conversion logic corresponding tocurrency_conversion_switch. - Check the knowledge base index list, confirm that the financing daily report data pulled via the API has been successfully synchronized and can be retrieved.
