Alibabacloud Oss Manage Network Probe

1. Always use aliyun ossutil probe — do not fabricate non-existent commands like aliyun oss api probe 2. Confirm all user-variable parameters before execution, especially bucket_name, object_name, download_url, local_path 3. Only retain probe objects when the user explicitly confirms; otherwise prefer temporary objects or explicit cleanup 4. For download-speed, choose a real object larger than 5 MiB for more stable results 5. In proxy, dedicated line, or custom domain scenarios, explicitly confirm --addr, --region, --endpoint 6. Use suggest parallel is as an empirical baseline, then do small-scale validation combined with actual business concurrency 7. For cycle-symlink, only diagnose — do not auto-fix 8. After command failure, prefer same-target validation (e.g. ossutil stat) — do not expand into listing buckets, guessing regions, trying unsupported flags, or reading local credential files 9. Do not expose AK/SK, STS tokens, or full presigned URL query strings in logs or final results 10. A successful presign, resolvable DNS, or reachable ping/traceroute does not guarantee the object exists or that the probe will succeed; conclusions must be based on actual probe/validation results
