What Data for This Category Looks Like
Data sources for coal chemical marketing content include internal enterprise marketing material libraries, public databases from coal industry associations, and third-party supply chain trading platforms. Three update frequency categories apply: quote data is synchronized daily, product parameter data is updated quarterly, and customer acquisition script templates are iterated every two months. Document structure is split into structured parameter tables and unstructured graphic materials. Structured fields include unique material identifier, applicable downstream scenarios, measurement unit, and effective date. Unstructured materials include associated project numbers and customer connection labels. Units primarily use tons and standard cubic meters, with some chemical derivatives marked in kilograms.
Constraints Imposed on HTTP Interfaces and External Systems
Multiple update frequency data sources require interfaces to support incremental pulling via timestamps, to avoid excessive bandwidth usage from full synchronization. Mixed structured and unstructured material types require interfaces to support both JSON format parameter requests and attachment upload capabilities. Coal chemical industry-specific measurement unit requirements mandate that numerical fields returned by interfaces include unit identifiers, to prevent parsing errors in downstream systems. Field design for associated project numbers requires interfaces to support precise filtering by project number, to adapt to targeted push scenarios in customer acquisition. Additionally, daily updated quote data requires interfaces to have low-latency response capabilities, to ensure the timeliness of marketing content.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
plugin_http_timeout | 300 seconds | Interface requests for coal chemical marketing content include structured parameters and attachments. Typical full response time ranges from 2 to 5 minutes |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Coal chemical product manuals and project tender documents often contain multiple high-definition drawings and tables, resulting in large single-file sizes |
incremental_sync_interval | 86400 seconds | Daily updated quote data requires daily incremental synchronization to avoid resource waste from full pull requests |
filter_field | ["project_id", "effective_date"] | Coal chemical marketing content needs to be filtered by project number and effective date to adapt to precise pushes in customer acquisition scenarios |
response_unit_append | true | Coal chemical data has diverse measurement units. Unit identifiers must be automatically attached to returned fields to prevent downstream parsing errors |
api_auth_type | api_key | External system interfaces require fixed key authentication to ensure access security for coal chemical marketing data |
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 on-site analysis, and it is recommended to test against your own samples before finalizing.
Three Common Mistakes
- Phenomenon: Custom HTTP plugin request parameters and response content only show partial fields, with no complete debug logs. Cause: The detailed log switch of the plugin is not enabled. The platform only records basic request links, and does not expose complete external system interaction details.
- Phenomenon: Interface call returns
400 Bad Request, with the prompt "Missing measurement unit field". Cause:response_unit_appendis not configured astrue, so the interface does not automatically attach unit identifiers such as tons and standard cubic meters for coal chemical data. - Phenomenon: Interface call times out, returning
504 Gateway Timeoutstatus code. Cause: The setplugin_http_timeoutis less than the response time of the external system, and does not adapt to the full loading cycle of coal chemical multi-attachment requests.
How to Confirm Proper Configuration
- Initiate an incremental synchronization request, check whether the time range of the returned material data matches the configured
incremental_sync_interval. - Upload a coal chemical product manual containing high-definition drawings, check whether the upload progress complies with the
UPLOAD_FILE_MAX_SIZElimit. - Call the interface to obtain quote data, check whether the numerical fields in the returned result have corresponding measurement units attached.
- Initiate a request filtered by project number, check whether the returned materials only include content from the target project.
