What the data for this category looks like
The data for oil and gas extraction financing daily reports primarily comes from third-party oil and gas industry financing databases, public announcements of listed companies on domestic and overseas exchanges, and project financing information publicly disclosed by oil and gas industry associations. It updates the previous calendar day’s public financing transactions on a T+1 daily basis. The data uses a structured format, with each record corresponding to a single project’s financing activity on a single day. Core fields include financing_id (unique project identifier), enterprise_name (name of the oil and gas extraction entity), financing_amount (financing amount), financing_type (financing method classification), investor_list (list of investors), disclosure_date (disclosure date), and block_location (region where the oil and gas block is located). The financing_amount field supports two currency units: RMB and USD. The disclosure_date field uses the YYYY-MM-DD standard format.
Constraints on HTTP interfaces and external systems
Because data sources include multiple third-party platforms and public disclosure channels, different data source authentication rules must be adapted to. These include API keys, OAuth2.0 signature verification, and other methods. Data updates only once per day. The polling interval for HTTP interfaces should not be too short, to avoid repeated pulling of data with no updates. Some fields such as block_location contain geographic region information. Input parameters must undergo invalid character verification to prevent interface request exceptions. The financing_amount field has multiple currency units. Unit conversion mapping rules must be added to the interface configuration, to ensure uniform formatting when synchronizing data to external systems. The investor_list array field, which includes multiple investors, requires the interface to support parsing and transmission of nested arrays. This adapts to the structured storage requirements of external project management systems.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
request_interval | 4 hours | Matches the T+1 update rhythm of oil and gas extraction financing daily reports, avoids invalid repeated pulling |
auth_type | API key + signature verification | Adapts to the general authentication requirements of most third-party oil and gas financing data sources |
field_mapping_rule | Direct mapping by source field name | Ensures field consistency for structured data, reduces adaptation costs for external systems |
unit_conversion_threshold | 1 million RMB | Matches the common currency unit conversion standards used in the domestic oil and gas industry financing sector |
webhook_verify_mode | Signature verification | Ensures access security for external push interfaces, prevents malicious requests |
batch_pull_page_size | 20 items per page | Balances interface response speed and the volume of data pulled in a single request, avoids timeouts |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by data format, data volume, and business rules. Specific issues require case-by-case analysis. Testing on local samples is recommended before finalizing configuration.
Three common errors
- Symptom: Calling an external financing API returns a
403 Forbiddenstatus code. Cause:auth_typeis not correctly configured to match the authentication rules of the target data source, leading to failed authentication verification. - Symptom: The interface prompts "Message receiving address verification failed" during Webhook push. Cause: The interface is not deployed to a publicly accessible network address, or no valid SSL certificate is configured and the certificate verification switch is not turned off.
- Symptom: The
financing_amountfield referenced using{{}}in an HTTP node cannot correctly parse the numerical value. Cause: The version is not upgraded to V4.8.18 or later. There is a known compatibility issue with{{}}format variables in older versions.
How to confirm the configuration is complete
- Manually call the configured HTTP interface, and verify that the returned
financing_idfield matches the financing project identifiers publicly disclosed by third-party data sources. - Start a scheduled pulling task, wait for one data update cycle, and confirm that the pulled
disclosure_datefield matches the financing information disclosed on the current day. - Configure a Webhook push test, and check whether the external receiving interface can normally receive and parse complete field content.
- Initiate a request using an incorrect API key, confirm that a
403 Forbiddenstatus code is returned, which proves that the authentication configuration is effective.
