🔁 Monitoring

Set monitorMode to changes and keep the same search scope and stateName in a scheduled task. The first complete run emits NEW rows. Later complete runs emit new, updated, and reappeared rows by default.

A missing listing becomes EXPIRED after two consecutive complete scans. It becomes REAPPEARED if it returns later. Blocked, malformed, empty, failed, or truncated scans never advance missing-job expiry state.

Full records suit research exports. Compact records keep stable identity, source dates, salary context, employer identity, and lifecycle fields for feeds and alerts. Webhook delivery is bounded and best effort. A delivery failure does not discard valid rows or monitoring state.

❓ FAQ

前程无忧会被拦截吗？

51job can return access challenges to automated clients. The Actor uses tested datacenter routing by default, bounded timeouts, and session rotation after a block. Residential routing with Singapore, Hong Kong, or Japan remains available as an opt-in fallback for larger runs that hit rate limits. If the source remains unavailable, the run fails visibly instead of returning a misleading empty dataset.

Does it collect private phone numbers?

No. The Actor reads public job listing fields only. It does not collect candidate profiles, private phone numbers, resumes, or login-only information.

前程无忧招聘数据有多新？

Each run reads the current public search surface. Rows keep the source issue date, source update date, and collection time separately, so downstream users can measure freshness.

Can it search every 51job role and city?

It supports the public search filters exposed in the input form and exact public search URLs. Search results can change, and access challenges can limit coverage. The run summary reports whether the selected scope completed.

🔄 Migrating from v1

Saved inputs using scrapeMode, searchQuery, jobArea, workYear, degree, outputFormat, or incrementalMode are accepted for one migration window. New tasks should use sourceMode, queries, cities, experience, education, outputMode, and monitorMode.

The v2 output replaces ambiguous aliases such as datePosted, applyUrl, lon, lat, experienceString, and degreeString with explicit source and normalized fields. Missing source values remain absent.
