Backend
- setting/payment.go: introduce default `USDExchangeRate` (7.3)
- model/option.go:
• inject `USDExchangeRate` into `InitOptionMap`
• persist & sync value in `updateOptionMap`
- controller/misc.go: expose `usd_exchange_rate` via `/api/status`
Frontend
- OperationSetting.js & SettingsGeneral.js:
• extend state/inputs with `USDExchangeRate`
• add form field “美元汇率 (non-top-up rate, pricing only)”
- ModelPricing.js already consumes `status.usd_exchange_rate`; no change needed
API
- Administrators can update the rate via `PUT /api/option` (key: `USDExchangeRate`)
- All clients receive the latest rate through `GET /api/status`
This closes the end-to-end flow for displaying model prices in both USD and CNY based on a configurable exchange rate.
Backend
1. controller/channel.go
• Always hydrate `ChannelInfo` from DB in `UpdateChannel`, keeping `IsMultiKey` true so `MultiKeySize` is recalculated.
2. model/channel.go
• getKeys(): accept both newline-separated keys and JSON array (`[ {...}, {...} ]`).
• Update(): reuse new parser-logic to recalc `MultiKeySize`; prune stale indices in `MultiKeyStatusList`.
Frontend
1. pages/Channel/EditChannel.js
• `handleVertexUploadChange`
– Reset `vertexErroredNames` on every change so the “ignored files” prompt always re-appears.
– In single-key mode keep only the last file; in batch mode keep all valid files.
– Parse files, display “以下文件解析失败，已忽略：…”.
• Batch-toggle checkbox
– When switching from batch→single while multiple files are present, show a confirm dialog and retain only the first file (synchronises state, form and local caches).
• On opening the “new channel” side-sheet, clear `vertexErroredNames` to restore error prompts.
Result
• “已启用 x/x” count updates immediately after editing multi-key channels.
• Vertex-AI key upload works intuitively: proper error feedback, no duplicated files, and safe down-switch from batch to single mode.
This commit refactors the application's error handling mechanism by introducing a new standardized error type, `types.NewAPIError`. It also renames common JSON utility functions for better clarity.
Previously, internal error handling was tightly coupled to the `dto.OpenAIError` format. This change decouples the internal logic from the external API representation.
Key changes:
- A new `types.NewAPIError` struct is introduced to serve as a canonical internal representation for all API errors.
- All relay adapters (OpenAI, Claude, Gemini, etc.) are updated to return `*types.NewAPIError`.
- Controllers now convert the internal `NewAPIError` to the client-facing `OpenAIError` format at the API boundary, ensuring backward compatibility.
- Channel auto-disable/enable logic is updated to use the new standardized error type.
- JSON utility functions are renamed to align with Go's standard library conventions (e.g., `UnmarshalJson` -> `Unmarshal`, `EncodeJson` -> `Marshal`).
Summary
1. **model/channel.go**
• Replaced the pointer-only `Value()` with a value-receiver implementation
• GORM can now marshal both `ChannelInfo` and `*ChannelInfo`, eliminating
`unsupported type model.ChannelInfo` runtime error.
2. **controller/channel.go**
• Refactored `getVertexArrayKeys()` – every element is now
- passed through `json.Marshal` when not already a string
- trimmed & validated before insertion
• Guarantees each service-account key is persisted as a **pure JSON string**
instead of the previous `map[...]` dump.
Result
• Channel creation / update succeeds without SQL driver errors.
• Vertex-AI batch & multi-key uploads are stored in canonical JSON, ready for
downstream SDKs to consume.
1. Backend
• `controller/channel.go`
– Added pagination (`p`, `page_size`) support to `SearchChannels`.
– Added independent `type` filter (keeps `type_counts` unaffected).
– Returned `total`, `type_counts` to match `/api/channel/` response.
2. Frontend
• `ChannelsTable.js`
– `loadChannels` / `searchChannels` now pass `p`, `page_size`, `id_sort`, `type`, `status` correctly.
– Pagination, page-size selector and type tabs work for both normal list and search mode.
– Switch for “ID sort” calls proper API and keeps UI state in sync.
– Removed unnecessary `normalize` helper; `getFormValues` back to concise form.
Result
• Search mode and normal listing now share identical pagination and filtering behavior.
• Type tabs show correct counts even after searching.
• “ID Sort” toggle no longer inverses actual behaviour.
WHAT’S NEW
• Backend
– Introduced `parseStatusFilter` helper to normalize `status` query across handlers.
– `GET /api/channel` & `GET /api/channel/search` now accept `status=enabled|disabled` to return only enabled or disabled channels.
– Tag-mode branch respects both `statusFilter` and `typeFilter`; SQL paths trimmed to one query + one lightweight `GROUP BY` for `type_counts`.
• Frontend (`ChannelsTable.js`)
– Added “Status Filter” `<Select>` (All / Enabled / Disabled) with localStorage persistence.
– All data-loading and search requests now always append `type` (when not “all”) and `status` params, so filtering & pagination are handled entirely server-side.
– Removed client-side post-filtering for type, preventing short pages and reducing CPU work.
– Tabs’ type counts stay in sync via backend-provided `type_counts`.
IMPROVEMENTS
• Eliminated duplicated status-parsing logic; single source of truth eases future extension.
• Reduced redundant queries, improved consistency of counts in UI.
• Secured key leakage with `Omit("key")` unchanged; no perf regressions observed.
Closes#1289
