HTTP Interfaces and External Systems for Film Theater

What This Category’s Data Looks Like

Film theater revenue yield data primarily comes from in-theater POS settlement systems and third-party film data service interfaces. Data synchronization for the current day is completed within 1 to 2 hours after daily business concludes. Each data entry includes fields such as theater code, unique film identifier, daily cumulative box office, daily scheduled showtimes, average per-screen audience count, and single-hall daily revenue. All field units are uniformly Renminbi yuan, showtimes, and audience counts. There are no nested data layers. Each entry corresponds to the daily operating data of one theater and one film.

What Constraints These Characteristics Impose on HTTP Interfaces and External Systems

Data sources are scattered, and updates are concentrated in a fixed window. This requires HTTP interfaces to support batch requests during peak periods to avoid interface blocking. Individual data fields are flat and non-nested, so no complex JSON parsing logic is needed. However, field names and units must be strictly matched, otherwise data matching will fail. The daily data synchronization window is fixed. External systems must complete data pulling within this window, otherwise delayed data will be retrieved. Some third-party data sources have interface rate limits. Reasonable request intervals must be configured to avoid triggering these rate limiting mechanisms.

How to Set Configurations

Configuration Item	Recommended Value	Rationale
`external_api_request_timeout`	`30 seconds`	Adapts to the standard response duration of film theater data sources, avoids missing the fixed synchronization window due to timeout
`max_batch_request_size`	`150 items per request`	Matches the scale of theater-film data pulled in a single batch, reduces interface load
`api_request_rate_limit`	`8 requests per minute`	Complies with rate limiting rules for most third-party film data interfaces, adapts to daily batch pulling requirements
`field_strict_match`	`Enabled`	Film theater data fields are flat and have fixed units. Strict matching avoids parsing deviations
`scheduled_sync_time`	`Daily 20:30-21:30`	Corresponds to the standard data update window after theater business closes, obtains the latest same-day data
`retry_max_attempts`	`2 attempts`	Handles temporary interface fluctuations, avoids triggering rate limiting from repeated requests

The parameter values provided on this page are common starting points for configuration. Actual values are affected by data format, total data volume, and business rules. Each scenario requires separate analysis. It is recommended to test using your own samples before finalizing settings.

Three Common Mistakes

Symptom: External interface calls return Api response error: undefined with no specific error message. Cause: The field_strict_match parameter is not enabled, causing the field units returned by the interface to not match expectations, and an uncaught exception is thrown during parsing.
Symptom: Daily synchronization tasks time out and fail, returning a 504 Gateway Timeout status code. Cause: The synchronization window is configured too late, missing the data source update window, and pulling delayed data causes the request duration to exceed the threshold.
Symptom: Pulled data fields are missing, only containing some basic identifier fields. Cause: The max_batch_request_size parameter is not set, the single request data volume is too large, and the third-party interface truncates the return to incomplete data.

How to Confirm the Configuration Is Complete

Initiate a small-batch test request, check whether the returned data fields match the configured field_strict_match rules.
Manually trigger a synchronization task during the configured scheduled_sync_time window, verify whether the pulled data is the latest daily theater operating data.
Check the interface call logs, confirm that the request frequency does not exceed the configured api_request_rate_limit threshold, and there are no error logs of type 403 Forbidden or 504 Gateway Timeout.
Compare with the official documentation of the third-party data source, confirm that the pulled field units fully match the configured parsing rules.
