What this category of data looks like
Residential development yield datasets are sourced from internal cost accounting systems of real estate enterprises, sales filing data from housing and construction authorities, and project progress ledgers. Data is updated on a regular monthly basis, with additional updates for major milestones such as project launch or completion. Single-project datasets are structured documents containing the following fields: project number, plot location, total investment, salable area, cumulative receipts, current period expenditure. The units for these fields are string, address text, Chinese Yuan (CNY), square meters, CNY, CNY respectively. No percentage-based statistical fields are included.
What constraints do these characteristics impose on the sharing and embedding workflow
Structured datasets bound to a single project require sharing links to carry a unique project ID parameter, to avoid mixing data across projects. The update rhythm of monthly updates plus milestone-based additional updates requires embedded components to set a fixed refresh cycle, to prevent displaying expired data. Multiple fields have strict unit attributes such as CNY and square meters. Embedded frontends must retain the original unit display, and must not perform unauthorized conversions. Data is associated with internal ledgers and filing information. Shared content must include a data update timestamp to clarify the timeliness boundary, and prevent recipients from using expired business data.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
shareLinkEnableParams | ["projectId", "updateTime"] | Matches the field requirements of single-project datasets, carrying project ID and update time to ensure accurate data positioning |
embedRefreshInterval | 2592000 seconds | Aligns with the monthly update rhythm; 2592000 seconds equals 30 days, preventing cached expired data |
embedAllowCrossOrigin | ["your-project-domain.com"] | Restricts valid domains for embedded pages, complying with security access requirements for internal systems |
shareMetadataDisplay | true | Displays the data update timestamp to clarify data timeliness, matching the update rhythm characteristics |
shareAuthMode | "apiKey" | Residential development data is internal business data; API key authentication prevents unauthorized access |
shareExpireDays | 30 days | Aligns with the monthly update cycle, automatically expiring after the set period to avoid sharing expired data |
The parameter values provided on this page are all common recommended 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 the configuration.
Three common mistakes
- Symptom: Embedded pages return a 403 status code when calling the interface, and cannot load residential development data. Cause:
shareAuthModeis not configured to authentication mode. The open-source version's default sharing link does not enable identity verification, resulting in unauthorized access being blocked. - Symptom: The login-free sharing dialog icon is not modified as required, and displays the default style. Cause: No custom icon parameter is set in the embedded configuration, or no compliant icon file has been uploaded.
- Symptom: Shared links fail to load historical conversation records after opening, and the conversation list field is empty. Cause: No session ID parameter is carried in the sharing link, or the
maxContextparameter is not configured to retain sufficient context length.
How to confirm the configuration is complete
- Access the configured sharing link, and check if the URL parameters include the project ID and update time fields.
- View the displayed data on the embedded page, and confirm that the original units of all fields are displayed normally.
- Use an unauthorized API key to access the embedded interface, and confirm that the interface returns an authentication failure prompt.
- Wait for the preset expiration period, then access the old sharing link again, and confirm that the link cannot load normally.
