From a4aa860d04f1b459b1c22c9a586aba0d9cae995a Mon Sep 17 00:00:00 2001 From: lb1038678031 <1038678031@qq.com> Date: Fri, 28 Aug 2026 16:45:04 +0800 Subject: [PATCH 1/2] feat: replace AI chat UI with TDesign React Chat and add homepage chat switches - New AnswerChatBot adapter component wraps @tdesign-react/chat ChatBot with the Answer backend contract: custom SSE parsing (markdown + thinking blocks from reasoning_content), vote actions bridged to the conversation vote API, conversation history rehydration. - The AI assistant page now renders AnswerChatBot; the legacy Sender/Bubble components stay for other pages. - New site AI switches: home_chat_enabled (floating AI entry on the homepage) and home_chat_guest_enabled (logged-out visitors can chat; guest sessions stay client-side and are never persisted, voting off). - POST /chat/completions moves to the unauthenticated route group; the handler enforces the guest switch itself and runs guest sessions fully in memory with a system prompt prepended. - zh/en translations for the new switches and chat strings. --- i18n/en_US.yaml | 6 + i18n/zh_CN.yaml | 8 + internal/controller/ai_controller.go | 36 +++ internal/controller/siteinfo_controller.go | 2 + internal/router/answer_api_router.go | 10 +- internal/schema/siteinfo_schema.go | 18 +- ui/.npmrc | 3 +- ui/package.json | 3 + ui/src/common/interface.ts | 4 + ui/src/components/AnswerChatBot/index.tsx | 259 +++++++++++++++++++++ ui/src/components/HomeChatWidget/index.tsx | 167 +++++++++++++ ui/src/pages/Admin/AiSettings/index.tsx | 66 ++++++ ui/src/pages/AiAssistant/index.tsx | 222 ++---------------- ui/src/pages/Questions/index.tsx | 2 + ui/src/stores/aiControl.ts | 23 +- ui/src/utils/guard.ts | 2 + 16 files changed, 620 insertions(+), 211 deletions(-) create mode 100644 ui/src/components/AnswerChatBot/index.tsx create mode 100644 ui/src/components/HomeChatWidget/index.tsx diff --git a/i18n/en_US.yaml b/i18n/en_US.yaml index 5d1faa3e0..d312e2dee 100644 --- a/i18n/en_US.yaml +++ b/i18n/en_US.yaml @@ -2347,6 +2347,12 @@ ui: label: AI enabled check: Enable AI features text: The AI model must be configured correctly before it can be used. + home_chat: + label: Show AI assistant on homepage + tip: Shows a floating AI assistant entry at the bottom-right of the homepage. + home_chat_guest: + label: Allow guests to use the homepage AI assistant + tip: Logged-out visitors can chat with the homepage AI assistant; guest conversations stay in the browser and are never saved. provider: label: Provider api_host: diff --git a/i18n/zh_CN.yaml b/i18n/zh_CN.yaml index f16ed9fad..812f6ba21 100644 --- a/i18n/zh_CN.yaml +++ b/i18n/zh_CN.yaml @@ -856,6 +856,8 @@ ui: copy: 复制 ask_a_follow_up: 提出后续问题 ask_placeholder: 提问 + thinking: 思考中… + thoughts: 思考过程 notifications: title: 通知 inbox: 收件箱 @@ -2305,6 +2307,12 @@ ui: label: AI 已启用 check: 启用AI功能 text: AI 模型必须正确配置才能使用。 + home_chat: + label: 首页展示 AI 助手 + tip: 开启后将在网站首页右下角展示 AI 助手悬浮入口。 + home_chat_guest: + label: 允许游客使用首页 AI 助手 + tip: 开启后未登录访客也可使用首页 AI 助手；游客会话仅保留在浏览器中，不会被保存。 provider: label: 提供商 api_host: diff --git a/internal/controller/ai_controller.go b/internal/controller/ai_controller.go index e7495253b..6d01b78b2 100644 --- a/internal/controller/ai_controller.go +++ b/internal/controller/ai_controller.go @@ -211,6 +211,14 @@ func (c *AIController) ChatCompletions(ctx *gin.Context) { } req.UserID = middleware.GetLoginUserIDFromContext(ctx) + // The route is registered as unauthenticated so logged-out visitors can + // use the homepage AI chat; guests are only served when the admin enables + // guest access, and their conversations are never persisted. + if req.UserID == "" && !aiConfig.HomeChatGuestEnabled { + handler.HandleResponse(ctx, errors.Unauthorized("guest access to AI chat is not enabled"), nil) + return + } + data, _ := json.Marshal(req) log.Infof("ai chat request data: %s", string(data)) @@ -351,6 +359,34 @@ func (c *AIController) initializeConversationContext(ctx *gin.Context, model str Model: model, } + // Guest session: storage is never touched.
