HTTP Interfaces and External Systems for Auto Parts

What Data for This Category Looks Like

Marketing content data for auto parts comes primarily from internal enterprise product management systems, supply chain collaboration platforms, and original equipment manufacturer supporting documents. The data structure includes two parts: structured fields and rich-text marketing content.

Structured fields include part numbers, compatible vehicle ranges, materials, rated parameters, compliance certification marks, and more. Units cover physical quantities such as millimeters, newton-meters, volts, and others.

Update frequency varies by business scenario: full updates trigger when new auto parts launch, routine inventory changes sync at business nodes, and compliance certification updates trigger after internal audit processes complete.

Constraints Imposed by These Characteristics on HTTP Interfaces and External Systems

The unique identifier for structured fields (part number) requires external systems to carry accurate part numbers as query or creation parameters when calling interfaces, to avoid data confusion and duplicate entry.

The multi-value attribute of compatible vehicle ranges requires interfaces to support array-type filter parameters, to meet demand for batch querying marketing content by vehicle model.

Rich-text content comes with attachments such as high-definition product images and technical manuals. Interfaces must support multipart/form-data format requests, and require reasonable file size limits to be configured.

Differentiated update rhythms require interfaces to provide both single-item update and batch import endpoints, to adapt to full synchronization scenarios for new product launches and real-time updates for daily inventory.

How to Set Configurations

Configuration Item	Recommended Value	Rationale
`UPLOAD_FILE_MAX_SIZE`	`200 MB`	Auto parts marketing content often includes high-definition product images and technical manuals, which have large individual file sizes. 200 MB covers most scenarios
`PARSE_FILE_TIMEOUT_SECONDS`	`300 seconds`	Technical manual documents have long content, and parsing takes longer than general documents. Sufficient time must be reserved to complete parsing
`dataset_recall_topk`	`Top 8–12 entries`	Auto parts marketing content needs to cover multi-dimensional information such as compatible vehicles and parameters. Too many recalled entries increase context redundancy, while too few fail to cover user query needs
`api_request_timeout`	`60 seconds`	External system calls may involve batch data synchronization. 60 seconds balances request stability and response efficiency
`metadata_required_fields`	`["零件编号", "适配车型"]`	The core identifier of auto parts marketing content is the part number. Compatible vehicle models are a high-frequency filter condition for user queries. Mandatory verification is required to ensure data accuracy
`batch_import_max_count`	`500 entries per batch`	Large single batch sizes during bulk inventory or new product data synchronization easily cause interface timeouts. 500 entries balances synchronization efficiency and interface stability

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. It is recommended to test on your own samples before finalizing settings.

Three Common Mistakes

When calling the /api/core/dataset/collection/create/localFile interface, metadata fields are not correctly recognized. This occurs because required fields configured in metadata_required_fields are not passed as parameters, or field names do not match the configuration requirements.
A 415 Unsupported Media Type error occurs during Java integration. This occurs because the file and metadata are not submitted using multipart/form-data format, and pure JSON format is mistakenly used for the request.
Specified knowledge base content cannot be recalled when calling the chat interface. This occurs because the datasetIds field is not included in the request parameters to specify the target knowledge base ID, or the passed ID format does not meet system requirements.

How to Confirm Configurations Are Correct

Call the single-file upload interface, upload a parts technical document that matches the category characteristics, and check whether the returned result includes the preset required metadata fields.
Initiate a batch import request, import a preset number of structured data entries, and check that the number of successful entries returned by the interface matches the actual number of submitted entries.
Initiate a chat request, specify the target knowledge base ID, and check that the returned result only includes auto parts marketing content from that knowledge base.
View the system monitoring dashboard, confirm that the API request timeout rate meets the business preset tolerance range, and that there are no format error logs.
