What Data Looks Like for This Category
This category's data typically comes from ERP/WMS systems, barcode or RFID identification devices, procurement and production work orders, storage location management modules, AGV or material handling systems, and weighing equipment. Daily generated documents include receiving slips, putaway slips, material picking and return slips, inventory transfer slips, inventory count sheets, lot ledgers, first-in first-out (FIFO) and material expiration date records. Data update frequencies cover real-time scenarios (e.g., barcode-based receiving, AGV scheduling), daily updates (e.g., inventory summaries), and monthly inventory counts (e.g., book vs. physical stock reconciliation). Core fields include material code, lot number, storage location number, inspection status, expiration date, and inventory quantity.
Constraints Imposed on HTTP Interfaces and External Systems
Data sources for this category are scattered, with significant differences in update rhythms. They include both real-time data streams such as AGV scheduling and barcode-based receiving, and batch data such as daily inventory summaries and monthly inventory counts. Daily documents involve multi-dimensional fields including material code, lot number, inspection status, and expiration date. HTTP interfaces must support multi-dimensional filtering and querying by material, lot, storage location, and other criteria. They must also adapt to pagination requirements for batch data transmission. Additionally, the linked audit logic for material expiration dates and inspection status requires interface return data to include all fields needed for associated validation. This prevents downstream links from needing to supplement additional information.
Configuration Guidelines
This document adapts to the HTTP interface configuration process for FastGPT v4.17.0.
| Configuration Item | Recommended Practice | Rationale |
|---|---|---|
Authorization | Carry a Bearer token with a 1-hour validity period | Adapts to the API authentication rules of ERP/WMS systems. Avoids frequent token re-acquisition, and ensures authentication efficiency. |
variables | Bind material code and lot number as global variables | Simplifies parameter passing during multi-interface calls. Adapts to parameter reuse in batch audit scenarios, and reduces repetitive configuration workload. |
responseData | Return only four core fields: material code, lot number, inspection status, expiration date | Reduces data transmission volume. Lowers field parsing costs for downstream audit links, and aligns with core audit requirements for warehousing scenarios. |
| Interface timeout period | 600 seconds | Adapts to the transmission duration of monthly inventory batch data. Avoids timeout errors caused by excessive data volume. |
| Request retry count | 3 times | Addresses interface call failures caused by temporary network disconnections of AGV equipment. Ensures stability of real-time data synchronization. |
Three Common Configuration Mistakes
- An error of
column vector does not existis returned after calling the interface. The cause is that the vector extension initialization script was not re-executed in the associated PostgreSQL database, resulting in the vector type field not being created correctly. - When using an API to call the audit interface, the conversation log displays title content but the audit result is empty. The cause is that the lot number parameter was not bound in
variables, causing the interface to not filter inspection data for the corresponding lot. - A timeout error is triggered during batch synchronization of monthly inventory data. The cause is that pagination transmission configuration was not set, and the single transmission data volume exceeded the interface's carrying limit.
How to Verify Successful Configuration
- Call the test interface, check that the returned
responseDataonly includes the preset core fields, to verify that the parameter configuration takes effect. - Send a request containing an invalid lot number, confirm that the interface returns a clear parameter error prompt, to verify that the authentication and parameter verification logic is working normally.
- Simulate monthly batch data transmission, check that the interface response duration meets the preset timeout threshold, to verify that the pagination configuration adapts to batch scenarios.
- Disconnect the simulated AGV equipment network, retry the interface call, confirm that the preset number of retries is reached before an alarm is triggered, to verify that the retry mechanism is working.
