HTTP Interfaces and External Systems for Aquaculture

What Data for This Category Looks Like

Data comes from IoT water quality sensors deployed at aquaculture ponds, automated feed dispensing equipment, breeding ledger management systems, and disease warning terminals. Update frequency follows these patterns:

Water quality monitoring data updates every 5 to 15 minutes
Feeding records are generated in real time for each individual feeding action
Disease warning data is pushed immediately when abnormal thresholds are triggered
Daily breeding ledger data is aggregated once per day

The structure of individual data documents includes these fields: unique pond identifier, monitoring timestamp, dissolved oxygen concentration (mg/L), pH value, water temperature (℃), total daily feeding weight (kg), and disease warning level. All fields have clear physical units. Some pond batch information uses a nested structure, including sub-fields such as breeding species and stocking density.

Constraints on HTTP Interfaces and External Systems From These Data Characteristics

High-frequency updated water quality data requires interfaces to support batch retrieval by pond ID and time range. The volume of data retrieved in a single request should not be too large to avoid timeouts. Nested pond batch information requires interfaces to support parsing nested JSON fields. Without this support, key information such as breeding species cannot be extracted. Real-time pushed disease warning data aligns with webhook callback patterns. This approach helps reduce interface load. The requirement that fields carry clear physical units requires unified unit validation rules in interface configurations. This prevents parsing errors caused by non-standard unit data being passed in.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`API_REQUEST_TIMEOUT`	`30-60 seconds`	Aligns with response time requirements for high-frequency water quality data interfaces, prevents request interruptions caused by network fluctuations
`UPLOAD_ALLOWED_DOMAINS`	`.fish-sensor.cn, .farm-ledger.com`	Allows requests initiated by breeding IoT devices and ledger systems from their domains, blocks uploads and calls from unauthorized domains
`PARSE_BATCH_SIZE`	`200-500 records/request`	Matches the daily water quality data generation volume for a single pond, balances interface throughput and data integrity
`WEBHOOK_SIGNATURE_VERIFICATION`	`Enabled`	Verifies the legitimacy of disease warning push requests, prevents unauthorized data injection into the system
`REQUEST_RETRY_TIMES`	`2 times`	Addresses common network fluctuations in breeding scenarios, reduces data loss caused by temporary interruptions
`JSON_ESCAPE_HANDLING`	`Auto-escape and deduplicate`	Processes escape characters returned by interfaces, resolves issues where downstream requests carry extra backslashes

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

Three Common Configuration Mistakes

Issue: Calling the create_folder interface returns a 400 Bad Request status code. The cause is failing to correctly specify the parentId parameter as a valid ID of an existing directory, or failing to use the application/json format for the request body.
Issue: IoT camera images embedded in marketing content fail to load, returning a 403 Forbidden status code. The cause is failing to add the camera device's domain to the UPLOAD_ALLOWED_DOMAINS list, resulting in the reference being blocked.
Issue: JSON data returned by HTTP requests contains excess backslashes when passed to downstream interfaces, leading to parsing failures. The cause is that the JSON_ESCAPE_HANDLING configuration is not enabled, so escape characters returned by the original interface are not automatically processed.

How to Confirm Configuration is Complete

Initiate a batch retrieval request for water quality data for a specified pond. Check that the response status code is 200 OK, and that the returned fields include expected core information such as pond ID, dissolved oxygen concentration, and water temperature.
Upload a test image from a breeding IoT device. Check that the fileUrl returned by the interface is accessible normally, with no permission block prompts.
Construct test JSON data containing escape characters, pass it to downstream interfaces through configured HTTP tool nodes. Check that the receiving end receives the original data with no remaining extra backslashes.
Trigger a simulated disease warning push. Check that the request body received by the webhook endpoint matches the test data exactly, with no tampering.
