What Data for This Category Looks Like
Data for this category comes from three sources:
- Official guide prices from public construction machinery complete machine manufacturers
- Real-time transaction records from second-hand equipment trading platforms
- Rental records from industry rental platforms
Two update schedules are in use:
- New machine guide prices are updated weekly
- Second-hand transaction and rental data are updated daily
Each data entry includes these fields: equipment model, production year identifier, current transaction price, benchmark reference price, and revenue-related calculation fields. All units use RMB yuan, units, and rental hours. No custom units are employed.
Constraints Imposed on Sharing and Embedding Workflows
The data characteristics of this category impose several core constraints on the sharing and embedding workflow:
- Data update frequencies differ. Cache configuration after embedding must distinguish between new machine data and second-hand/rental data to avoid displaying outdated information.
- Fields include multiple price and duration units. Embedding templates must retain dynamic unit binding logic, and unit text must not be hardcoded.
- Individual data entries rely on identifiers such as equipment model and production year for accurate matching. Sharing links must carry unique device identification parameters to avoid mixing market data across different equipment.
- Data sources include multiple public platforms. Shared content must include data source traceability identifiers to ensure embedded content can trace back to original information.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
share_auth_type | signed_url | Matches the traceability requirement for construction machinery data, prevents unauthorized embedding calls |
cache_expire_seconds | 86400 seconds or 604800 seconds | Differentiate based on data update frequency: use 86400 seconds for daily updated data, 604800 seconds for weekly updated data |
embed_query_params | device_id,data_source | Matches the requirements for unique device identification and data source traceability, ensures embedded content accurately matches target equipment |
data_source_tag_display | true | Display data source identifiers, complies with data traceability constraints and improves content credibility |
error_page_template | Query failed by device ID, please check if parameters are correct | Provides clear error prompts for scenarios where device identifiers are missing or invalid |
max_embed_response_length | 1200 characters | Adapts to the large number of fields in construction machinery data, avoids content truncation that affects display |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing values.
Three Common Configuration Mistakes
- Embedded sharing interface calls return a 403 Forbidden status code. Cause: The
signed_urlauthentication type is not configured, or no signed sharing link with a valid signature is generated. - Units displayed on the embedded page do not match the actual data units. Cause: Unit text is hardcoded, and unit parameters for dynamic fields are not bound.
- The embedded page displays market data for other equipment. Cause: The
device_idparameter is not configured inembed_query_params, or the passeddevice_idis invalid.
How to Confirm Configuration is Complete
- Open the generated sharing link, check that the link parameters include the fields specified in
embed_query_params, such asdevice_idanddata_source. - Modify the
device_idparameter value in the link, verify that the embedded page switches to the market data of the corresponding equipment. - Check the content area of the embedded page, confirm that the data source identifier is displayed, and verify that the
data_source_tag_displayconfiguration takes effect. - Wait for the corresponding data update cycle, refresh the embedded page, and verify that the page data is updated synchronously.
