+# KnowAI Core API 文档
+
+本文档详细介绍了 KnowAI Core 库提供的 API 接口和类型定义，供 Page 层项目使用。
+
+## 1. 库概述
+
+KnowAI Core 是一个通用的前端核心库，提供了 API 调用、认证管理、工具函数等基础功能。
+
+```typescript
+// 导入方式
+export * from './types';      // 类型定义
+export * from './api';        // API客户端和模块
+export * from './auth';       // 鉴权相关功能
+export * from './utils';      // 工具函数
+```
+
+## 2. API 客户端
+
+### 2.1 初始化 API 客户端
+
+```typescript
+import { createApi } from 'knowai-core';
+
+// 创建默认 API 客户端
+const api = createApi();
+
+// 或使用自定义配置
+const api = createApi({
+  baseURL: '/api', // 默认值
+  timeout: 10000,
+  headers: {
+    'Content-Type': 'application/json'
+  },
+  withCredentials: true
+});
+```
+
+### 2.2 API 客户端功能

+```
+
+## 9. 在 Page 层项目中的使用示例
+
+### 9.1 初始化 API 客户端和认证服务 (Nuxt 插件)
+
+```typescript
+// plugins/api.ts
+import { createApi, createAuthService } from 'knowai-core';
+
+export default defineNuxtPlugin(nuxtApp => {
+  // 创建API客户端
+  const api = createApi({
+    baseURL: '/api',
+    timeout: 15000
+  });
+
+  // 创建认证服务
+  const authService = createAuthService(api.client);
+
+  // 无需手动添加认证令牌，使用浏览器的 cookie-session 机制
+  // 会话由服务器端控制，前端通过API查询认证状态
+  api.client.addRequestInterceptor(
+    (config) => {
+      // 会话由浏览器自动管理，无需手动添加认证信息
+      return config;
+    },
+    (error) => Promise.reject(error)
+  );
+
+  // 添加响应拦截器（处理错误）
+  api.client.addResponseInterceptor(
+    (response) => response,
+    (error) => {
+      // 统一错误处理逻辑
+      console.error('API Error:', error);
+      return Promise.reject(error);
+    }
+  );
+
+  // 提供API客户端和认证服务给Nuxt应用
+  nuxtApp.provide('api', api);
+  nuxtApp.provide('authService', authService);
+  
+  // 提供模块化API服务
+  nuxtApp.provide('postApi', api.post);
+  nuxtApp.provide('userApi', api.user);
+  nuxtApp.provide('chatApi', api.chat);
+  nuxtApp.provide('modelApi', api.model);
+});
+```
+
+### 9.2 在页面中使用 API
+
+```typescript
+// pages/index.vue
+<script setup lang="ts">
+import { ref, onMounted } from 'vue';
+import { useNuxtApp } from '#app';

+      limit: 5,
+      days: 7
+    });
+    hotPosts.value = hotPostsResponse.data;
+    
+    // 获取帖子榜单（周榜，按点赞数排序）
+    const rankingResponse = await $postApi.getPostRanking({
+      limit: 10,
+      period: 'week',
+      type: 'likes'

+```
+
+### 9.4 检查用户认证状态
+
+```typescript
+// middleware/auth.ts
+import { useNuxtApp } from '#app';
+
+export default defineNuxtRouteMiddleware(async () => {

+// 页面内容...
+</script>
+```
+
+### 9.5 在 Pinia Store 中使用 API
+
+```typescript

+
+### 9.4 聊天功能使用示例
+
+```typescript
+// stores/chatStore.ts
+import { defineStore } from 'pinia';
+import { useNuxtApp } from '#app';
+import type { ChatSession, ChatMessage, GetChatSessionsRequest, GetChatMessagesRequest } from 'knowai-core';
+
+export const useChatStore = defineStore('chat', () => {
+  const { $chatApi } = useNuxtApp();
+  const sessions = ref<ChatSession[]>([]);
+  const currentSession = ref<ChatSession | null>(null);
+  const messages = ref<ChatMessage[]>([]);
+  const loading = ref(false);
+
+  // 获取会话列表
+  const fetchSessions = async (params?: GetChatSessionsRequest) => {
+    loading.value = true;
+    try {
+      const response = await $chatApi.getSessions(params);
+      sessions.value = response.sessions;
+      return response;
+    } finally {
+      loading.value = false;
+    }
+  };
+
+  // 获取会话消息
+  const fetchMessages = async (params: GetChatMessagesRequest) => {
+    loading.value = true;
+    try {
+      const response = await $chatApi.getMessages(params);
+      messages.value = response.messages;
+      return response;
+    } finally {
+      loading.value = false;
+    }
+  };
+
+  // 发送消息
+  const sendChatMessage = async (content: string, type: ChatMessageType) => {
+    if (!currentSession.value) return;
+    
+    try {
+      const response = await $chatApi.sendMessage({
+        sessionId: currentSession.value.id,
+        content,
+        type
+      });
+      messages.value.push(response.message);
+      return response.message;
+    } catch (error) {
+      throw error;
+    }
+  };
+
+  return {
+    sessions,
+    currentSession,
+    messages,
+    loading,
+    fetchSessions,
+    fetchMessages,
+    sendChatMessage
+  };
+});
+```
+
+### 9.5 模型模块使用示例
+
+```typescript
+// stores/modelStore.ts
+import { defineStore } from 'pinia';
+import { useNuxtApp } from '#app';
+import type { AIModel, ModelComment, GetModelDetailRequest } from 'knowai-core';
+
+export const useModelStore = defineStore('model', () => {
+  const { $modelApi } = useNuxtApp();
+  const plazaData = ref<{ models: AIModel[], hotRankings: any[], clickRankings: any[] } | null>(null);
+  const currentModel = ref<AIModel | null>(null);
+  const modelComments = ref<ModelComment[]>([]);
+  const loading = ref(false);
+
+  // 获取AI广场数据
+  const fetchAIPlaza = async () => {
+    loading.value = true;
+    try {
+      const response = await $modelApi.getAIPlaza();
+      plazaData.value = response;
+      return response;
+    } finally {
+      loading.value = false;
+    }
+  };
+
+  // 获取模型详情
+  const fetchModelDetail = async (modelId: string) => {
+    loading.value = true;
+    try {
+      const response = await $modelApi.getModelDetail({ modelId });
+      currentModel.value = response.model;
+      modelComments.value = response.comments;
+      return response;
+    } finally {
+      loading.value = false;
+    }
+  };
+
+  return {
+    plazaData,
+    currentModel,
+    modelComments,
+    loading,
+    fetchAIPlaza,
+    fetchModelDetail
+  };
+});
+```
+
+## 10. 注意事项
+
+1. **认证处理**：所有需要认证的接口通过浏览器的 cookie-session 机制自动处理，无需手动添加令牌，session 完全由服务器端控制
+2. **错误处理**：使用 try/catch 捕获 API 调用可能出现的错误
+3. **分页处理**：注意检查 `hasMore` 字段来实现分页加载
+4. **数据缓存**：建议在 store 中缓存常用数据，避免重复请求
+5. **类型安全**：使用 TypeScript 类型确保数据结构正确性
+6. **聊天会话管理**：注意处理聊天会话中的未读消息计数
+7. **模型数据**：AI广场数据是静态配置的，不需要分页参数
+
+## 11. 完整API参考
+
+详细的API参考请查看 `knowai-core/api/modules` 目录下的各个模块文件。
