Problem:
Upstream channels can reject monitor probes based on client fingerprint
(e.g. "only Claude Code clients allowed"). The monitor had no way to
customize the outgoing request to bypass such restrictions.
Solution:
Introduce reusable request templates that carry extra_headers plus an
optional body override; monitors reference a template and receive a
snapshot copy on apply. Template edits do NOT auto-propagate — users
must click "apply to associated monitors" to refresh snapshots, so a
bad template edit cannot instantly break all production monitors.
Data model (migration 112):
- channel_monitor_request_templates: id, name, provider, description,
extra_headers jsonb, body_override_mode ('off'|'merge'|'replace'),
body_override jsonb. Unique (provider, name).
- channel_monitors: +template_id (FK, ON DELETE SET NULL), +extra_headers,
+body_override_mode, +body_override (the three runtime snapshot fields).
Checker (channel_monitor_checker.go):
- callProvider + runCheckForModel accept a CheckOptions carrying the
snapshot fields. mergeHeaders applies user headers on top of adapter
defaults (forbidden list: Host / Content-Length / Transfer-Encoding /
Connection / Content-Encoding).
- buildRequestBody:
off -> adapter default body
merge -> shallow-merge over default; per-provider deny list
(model/messages/contents) protects the challenge contract
replace -> user body verbatim
- Replace mode skips challenge validation; instead HTTP 2xx + non-empty
extracted response text = operational, empty = failed.
- 4 new unit tests cover all three modes + replace/empty-response case.
Admin API:
- /admin/channel-monitor-templates CRUD + /:id/apply (overwrite snapshot
on all template_id=id monitors, returns affected count).
- channel_monitor request/response DTOs gain the 4 new fields.
Frontend:
- channelMonitorTemplate.ts API client.
- MonitorAdvancedRequestConfig.vue shared component for headers textarea
+ body mode radio + body JSON editor; used by both template and monitor
forms.
- MonitorTemplateManagerDialog.vue: provider tabs, list/create/edit/
delete/apply, live "associated monitors" count per row.
- MonitorFiltersBar: new 模板管理 button next to 新增监控.
- MonitorFormDialog: collapsible 高级 section with template dropdown
(filtered by form.provider, clears on provider change) + embedded
AdvancedRequestConfig. Picking a template copies its fields into the
form (snapshot semantics mirrored on the client).
- i18n zh/en entries for all new copy.
chore: bump version to 0.1.114.32
Monitor:
- callProvider now returns both textPath-extracted text and raw body;
runCheckForModel uses rawBody on non-2xx so history.message stops being
"upstream HTTP 503: " with empty body (gjson textPath produces "" for
error responses like {"error":{"message":"No available accounts..."}})
- truncateForErrorBody collapses whitespace then caps at 300 bytes
(monitorErrorBodySnippetMaxBytes); final truncateMessage still enforces
the 500-byte DB column cap
Frontend:
- MonitorFormDialog: primary_model input text color and ModelTagInput tags
now both track form.provider (via new getPlatformTextClass + existing
getPlatformTagClass with platform prop).
(cherry-picked from 1d3b0418; dropped gateway_handler logging改动，不在本 PR 范围)
Settings:
- New "功能开关" tab between 通用设置 and 安全与认证
- ChannelMonitorEnabled toggle: runner skips scheduling when false,
user-facing list returns empty
- ChannelMonitorDefaultIntervalSeconds (15-3600): pre-fills interval
when creating a new monitor; each monitor can still override
Bug fix:
- ModelTagInput now commits pending input on blur, not just Enter/Tab.
Previously clicking "save" with an un-Enter'd extra model would drop
the value (DB stored extra_models=[] even when user typed entries).
Backend:
- domain_constants: SettingKeyChannelMonitor{Enabled,DefaultIntervalSeconds}
- SettingService.GetChannelMonitorRuntime: lightweight getter used by
runner tick + user handler per-request (fail-open on DB error)
- Runner tickDueChecks: bails early when feature disabled
- ChannelMonitorUserHandler: checks feature flag before serving
- Comment on runner doc: scheduler state is implicit (every tick re-reads
ListEnabled from DB), so CRUD ops on monitors self-maintain the schedule
Bump VERSION to 0.1.114.25
