# 小程序首页接口文档
> 适用端:微信小程序(h5 仓库,Taro)
> 后台配置入口:PC 后台「客户端配置」菜单(首页轮播图 / 宫格导航 / 促销推荐卡片)
> 更新日期:2026-08-14
## 通用约定
| 项 | 说明 |
|---|---|
| 根地址 | `BASE_URL`(见 `src/utils/request.ts`,如 `http://localhost:8000/index.php` |
| 认证 | 请求头 `Authorization: Bearer {token}`,token 来自登录接口,本地存储 key `auth_token` |
| 响应包络 | `{ success: boolean, data: T, msg?: string, showType?: number }` |
| 失败处理 | `success=false``msg` 为中文错误信息;HTTP 401 表示登录过期,需重新登录 |
## GET /mini/home
首页配置聚合接口:一次返回轮播图、宫格导航、促销推荐卡片三组数据,均为**启用状态(status=1)**且按 `sort` 升序(越小越靠前)。
- **权限**:需登录(Bearer token
- **请求参数**:无
### 响应示例
```json
{
"success": true,
"msg": "ok",
"data": {
"banners": [
{
"id": 1,
"title": "新鲜直采",
"image_id": 123,
"link": "/pages/goods/detail?id=1",
"sort": 0,
"image_url": "http://localhost:8000/storage/uploads/2026/08/14/xxx.jpg"
}
],
"navs": [
{
"id": 1,
"name": "蔬菜专区",
"image_id": 124,
"link": "/pages/category/index?id=1",
"sort": 0,
"image_url": "http://localhost:8000/storage/uploads/2026/08/14/yyy.png"
}
],
"promos": [
{
"id": 1,
"title": "限时特惠",
"sub_title": "全场 8 折起",
"image_id": 125,
"link": "/pages/promo/detail?id=1",
"sort": 0,
"image_url": "http://localhost:8000/storage/uploads/2026/08/14/zzz.jpg"
}
]
}
}
```
### 字段说明
**banners(轮播图)**
| 字段 | 类型 | 说明 |
|---|---|---|
| id | number | 轮播图 ID |
| title | string | 标题(后台维护,可用于无障碍/占位) |
| image_id | number | 图片文件 IDsys_file),一般无需使用 |
| **image_url** | string \| null | 轮播图片完整 URL,直接用于 `<Image src>`;未传图时为 null |
| link | string | 小程序页面跳转路径,**空字符串表示点击不跳转** |
| sort | number | 排序值(已按此升序返回,前端无需再排) |
**navs(宫格导航)**
| 字段 | 类型 | 说明 |
|---|---|---|
| id | number | 导航 ID |
| name | string | 导航名称(宫格文字) |
| **image_url** | string \| null | 导航图标完整 URL |
| link | string | 小程序页面跳转路径,空字符串不跳转 |
| sort | number | 排序值 |
**promos(促销推荐卡片)**
| 字段 | 类型 | 说明 |
|---|---|---|
| id | number | 卡片 ID |
| title | string | 卡片标题 |
| sub_title | string | 副标题/促销文案,可能为空字符串 |
| **image_url** | string \| null | 卡片图片完整 URL |
| link | string | 小程序页面跳转路径,空字符串不跳转 |
| sort | number | 排序值 |
### 前端接入示例
`src/services/home.ts`(新增):
```ts
import { get } from '@/utils/request'
/** 首页轮播图项 */
export interface HomeBanner {
id: number
title: string
image_id: number
image_url: string | null
link: string
sort: number
}
/** 首页宫格导航项 */
export interface HomeNav {
id: number
name: string
image_id: number
image_url: string | null
link: string
sort: number
}
/** 首页促销推荐卡片 */
export interface HomePromo {
id: number
title: string
sub_title: string
image_id: number
image_url: string | null
link: string
sort: number
}
/** 首页配置聚合数据 */
export interface HomeConfig {
banners: HomeBanner[]
navs: HomeNav[]
promos: HomePromo[]
}
/** 首页配置(轮播图 + 宫格导航 + 促销卡片):GET /mini/home */
export function getHomeConfigApi() {
return get<HomeConfig>('/mini/home')
}
```
页面中使用(跳转需兼容空链接):
```tsx
const [config, setConfig] = useState<HomeConfig>({ banners: [], navs: [], promos: [] })
useEffect(() => {
getHomeConfigApi().then(res => setConfig(res.data))
}, [])
/** 统一跳转:link 为空不跳转 */
function handleLink(link: string) {
if (!link) return
Taro.navigateTo({ url: link })
}
```
### 注意事项
1. **三组数据均可能为空数组**(后台未配置或全部停用),页面需做空态处理。
2. `image_url` 可能为 `null`(后台未上传图片),渲染前判空。
3. `link` 为小程序内部页面路径(以 `/` 开头),用 `Taro.navigateTo` 跳转;若目标为 tabBar 页面需改用 `Taro.switchTab`(建议后台配置时避免填 tabBar 路径)。
4. 数据实时生效:后台修改后,小程序下次进入首页请求即为最新内容,无缓存。
5. 接口需登录后调用;未登录(401)会由 request 封装自动跳登录页。
