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.

-- Migration: 128_add_channel_monitor_request_templates
|
||
-- 加请求模板表 + 给 channel_monitors 加 4 个快照字段（template_id 关联引用 + extra_headers /
|
||
-- body_override_mode / body_override 三个真正运行时使用的快照）。
|
||
--
|
||
-- 设计要点：
|
||
-- 1) 模板与监控之间是「应用即拷贝」的快照语义，运行时 checker 不再回查模板表。
|
||
-- 模板 UPDATE 不会自动影响监控；只有用户主动「应用到关联监控」才会刷新快照。
|
||
-- 2) ON DELETE SET NULL：模板删除不级联清理监控；监控保留快照继续工作。
|
||
-- 3) extra_headers / body_override 都是 JSONB；body_override_mode 用 varchar（不是 enum）
|
||
-- 便于将来加新模式无需 ALTER TYPE。
|
||
-- 4) 同一 provider 内模板 name 唯一（允许 Anthropic + OpenAI 重名 "伪装官方客户端"）。
