HTTP Interfaces and External Systems for Power Grid

What this category of data looks like

Data for power grid equipment financing daily reports comes from power supply chain finance platforms, grid company bidding filing systems, and financing application ledgers of equipment manufacturers. Data is updated via full synchronization of the previous day’s data every early morning, and supports incremental pulling. Each individual data entry has 12 fixed fields: full manufacturer name, project number, equipment type (e.g., transformer, switchgear, transmission tower), financing amount, financing term, lending bank, project location, application time, disbursement time, approval status, update time, associated project number.

Financing amount is measured in ten thousand RMB. Financing term is measured in natural months. Project number is an 18-character alphanumeric unique code. Update time uses ISO 8601 format timestamps.

What constraints do these characteristics impose on HTTP interfaces and external system integration

The dedicated fields and update schedule of power grid equipment financing daily reports impose multiple constraints for HTTP interface and external system integration. First, equipment type has fixed enumeration values. The interface must validate that incoming equipment type parameters are included in the preset enumeration list, otherwise return a 400 Bad Request error. Second, project number is a unique code. The interface must support exact queries by project number to avoid returning unrelated data. The daily update schedule requires the interface to support incremental pulling via the update_time parameter, reducing bandwidth consumption from full data transfers. Additionally, the fixed units for financing amount and financing term require the interface to return data with unified unit formats, with no mixed units. External systems do not need to perform additional unit conversion when connecting.

How to configure

Configuration Item	Recommended Value	Rationale
`pageSize`	`20–50`	Power grid equipment financing daily reports have many fields per entry. Limiting the number of entries per page to 20-50 prevents interface response timeouts
`update_time_start`	`Current time minus 24 hours`	Adapts to the daily update rhythm of daily reports, enables incremental pulling and reduces duplicate data transfers
`PARSE_FILE_TIMEOUT_SECONDS`	`300 seconds`	Processing structured financing daily report documents requires parsing multiple industry-specific fields. Setting the timeout to 300 seconds covers complex parsing scenarios
`UPLOAD_FILE_MAX_SIZE`	`50 MB`	Original financing daily report files are mostly Excel or CSV format, and single files typically do not exceed 50 MB to avoid upload failures
`recall_top_k`	`Top 10 entries`	Targets the core business fields of financing daily reports (financing amount, project location) for recall, prioritizing alignment with business scenarios
`FILE_PARSE_HTML_ENABLE`	`Enabled`	Supports parsing HTML interface documents generated by Javadoc, extracting interface parameters, return fields and other content

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to test against your own samples before finalizing.

Three common errors

Symptom: When passing different pageNum parameters, the interface returns an identical dataset with no pagination differences. Cause: The interface does not correctly implement pagination logic, does not slice data based on pageNum and pageSize, and only returns the full dataset.
Symptom: After uploading a Javadoc-format HTML interface document, the knowledge base contains no parsed content. Cause: The FILE_PARSE_HTML_ENABLE configuration is not enabled, and only plain text or Markdown format files are recognized.
Symptom: After enabling the file upload function in the frontend interface, the conversation interface cannot receive uploaded files. Cause: The file upload permission for the conversation interface is not configured, or the request does not carry the Content-Type request header of type multipart/form-data.

How to verify correct configuration

Call the interface with different pageNum and pageSize parameters, check if the number of returned dataset entries and offset meet expectations, to confirm the pagination logic works correctly.
Upload a small Javadoc-format HTML document, check if the knowledge base extracts interface fields, parameter descriptions, return examples and other content, to confirm the HTML parsing configuration is active.
After configuring the file upload permission for the conversation interface, send a simulated request with valid file parameters, check if the interface returns structured data parsed from the file.
Set the update_time_start parameter to a timestamp from the last 24 hours, call the interface to check if all returned data are financing daily reports updated within that time period, to confirm the incremental pulling logic works correctly.
