HTTP Interfaces and External Systems for Infrastructure Construction Marketing Content

Data for infrastructure construction marketing content primarily originates from government housing and urban-rural development department bidding

What the data for this category looks like

Data for infrastructure construction marketing content primarily originates from government housing and urban-rural development department bidding announcements, internal enterprise project case libraries, qualification filing documents, and shared data from industry partners. Data updates follow three schedules: bidding projects receive real-time push updates, project case libraries are synchronized quarterly, and qualification documents are updated after annual audits are completed. Each individual document uses a fixed structure, including fields such as project name, construction location, budget amount, construction period requirements, qualification thresholds, winning bidder, and coordination contact person. Budget amount is measured in ten thousand yuan, construction period in calendar days, and floor area in square meters.

What constraints these characteristics impose on HTTP interfaces and external systems

The multi-source nature, fixed but comprehensive field structure, and real-time update requirements of infrastructure construction marketing content create multiple constraints for HTTP interfaces and external systems. The real-time update need for bidding projects requires interfaces to support high-frequency requests or event push mechanisms, to avoid missing new customer acquisition leads. The fixed, comprehensive field structure requires interface requests to validate required fields: construction location and budget amount cannot be left empty. Differences in data formats across multiple sources require the interface layer to configure field mapping rules, to adapt to the return structures of different external systems. The relatively lengthy nature of individual documents requires adjusting interface timeout thresholds and request body size limits, to accommodate long-text transmission and parsing.

How to set configurations

Configuration ItemRecommended SettingRationale
API_KEYApplication-specific secret key to restrict access permissionsOnly allows authorized external systems to call the designated infrastructure construction marketing content application, to prevent unauthorized access
UPLOAD_FILE_MAX_SIZE10 MBAdapts to the single-file size of infrastructure construction bidding announcements and case documents, to avoid failures when uploading large files
PARSE_FILE_TIMEOUT_SECONDS300 secondsAdapts to the parsing requirements of long-text marketing documents, to avoid parsing timeouts caused by large document content
RECALL_TOP_KTop 8 entriesMatches the multi-field characteristics of infrastructure construction marketing content, to recall a sufficient number of relevant projects and cases
HTTP_REQUEST_TIMEOUT120 secondsAdapts to the data synchronization and field mapping processes when connecting to external systems, to avoid timeouts for long-link requests
FIELD_MAPPING_RULESMap internal fields according to government announcement standardsUnifies the format of multi-source infrastructure data, to ensure consistent field structures obtained by external systems

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

Three common configuration errors

  • Calling the /api/v1/chat/completions interface returns a 401 status code, with the interface response indicating unauthorized access. The cause is that API_KEY is not configured or is configured incorrectly, and the access permission for the corresponding application is not bound.
  • After uploading an infrastructure construction bidding document, a parsing timeout error is returned, with the interface prompting parsing failure. The cause is that the PARSE_FILE_TIMEOUT_SECONDS configuration was not adjusted, and the default value was used, resulting in incomplete parsing of long text.
  • External systems receive field data missing construction location information, with the address field appearing empty in returned data. The cause is that FIELD_MAPPING_RULES were not configured, and corresponding fields from internal data sources were not mapped to standard formats.

How to confirm configurations are correct

  • Call the /api/v1/chat/completions interface, initiate a request with a valid API_KEY, and check that the response status code is 200 and includes expected conversation content.
  • Upload a single long-text infrastructure construction document, wait for parsing to complete, and check that the parsing progress prompt contains no timeout errors, confirming that the configuration adapts to the current document length.
  • Connect to an external bidding data source, initiate a data synchronization request, and check that returned fields include required items such as construction location and budget amount, confirming that the field mapping configuration takes effect.
  • Simulate high-frequency requests to obtain real-time bidding projects, check that the interface response frequency meets business requirements, confirming that timeout and request frequency configurations match the business scenario.
