feat(diy): 自动获取位置 + 反查城市 + 过期重取 + 重新请求首页
实现 DIY 首页左上角位置选择器在用户授权后自动获取坐标、反查最近城市,
并让首页在 5 分钟过期后自动重新请求以匹配新坐标的 DIY 模板。
主要改动:
- App.vue:get_user_location 重写
- 守护条件扩展为 5 条件 OR 判定(5 分钟过期 + name 占位 + status + 无缓存 + is_force)
- 写入 storage 加 updated_at 时间戳
- 成功时 uni.$emit('onLocationReady', address) 通知订阅方
- 新增 fail 回调:写 status:0 占位 + 触发事件,修复权限拒绝后无限重弹的隐藏 bug
- pages/index/index.vue
- onLoad 订阅 onLocationReady 事件
- 收到事件后调 init({is_cache:0, loading:1}) 重新请求首页(让后端按新坐标推荐)
- onUnload 清理订阅
- components/choice-location/choice-location.vue
- mounted 订阅 onLocationReady 事件
- 仅当 name 是占位时才重新反查 /vr_ticket/geo/city
- beforeDestroy 清理订阅
文档:
- 新增 docs/diy-home-location-work-record-20260628.md 完整留档
- 标注 docs/city-based-diy-template-plan.md '前端零改动' 假设已过期
- 修正 docs/troubleshoot/weixin-location-permission.md §七.5 警告的状态
验证:DIY 首页左上角从'当前位置'成功切换为'厦门市'(用户实机验证)

## 〇、更新历史
|
||||
|
||||
### 2026-06-28 部分修正
|
||||
|
||||
**关于本方案"前端零改动"假设(§1.2.4、§3.2 C03、§4.3)**:
|
||||
|
||||
> ⚠️ **本假设已被打破**。前端已做大量改动以支持位置自动获取 + 城市反查。详细实现见 [diy-home-location-work-record-20260628.md](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/docs/diy-home-location-work-record-20260628.md)。
|
||||
|
||||
**已实现的前端改动**(2026-06-28):
|
||||
1. `App.vue:get_user_location` 重写(5 条件守护 + fail 占位 + `onLocationReady` 事件)
|
||||
2. `pages/index/index.vue` 监听事件 + 重新请求首页(让后端按新坐标推荐 DIY 模板)
|
||||
3. `components/choice-location/choice-location.vue` 监听事件 + 城市反查
|
||||
4. 完整验证:DIY 首页左上角从"当前位置"自动切换为"厦门市"
|
||||
|
||||
**后端能力依赖**(已由另一名同事提供):
|
||||
- `vr_ticket/geo/city` 距离匹配接口(>150km 报 code:-1)
|
||||
- 业务后端按 URL 里的 `user_lng` / `user_lat` 自动推荐对应城市的 DIY 模板
|
||||
|
||||
**未变的内容**:
|
||||
- 后端控制器逻辑(不在本前端任务范围)
|
||||
- 城市中心点数据(Region 表)
|
||||
- DIY 模板命名约定(`home_<city_id>` / `home_default`)
|
||||
|
||||
**为什么打破"前端零改动"假设**:
|
||||
- 原方案假设"用户进入首页前已经选过城市"——但**实际场景**是"用户首次进首页就要按位置自动推荐"
|
||||
- 现有的 `get_user_location` 有一个**长期隐藏 bug**:已授权用户后续进首页不会再重新获取位置(守护条件 `result == null` 把第二次进入挡在外面)
|
||||
- 需要前端在拿到新坐标后**主动**重新请求首页,让后端按新坐标推荐对应 DIY 模板

## 一、任务背景
|
||||
|
||||
VR 票务项目需要支持"基于地理位置的城市化 DIY 装修模板自动加载"(参考 [city-based-diy-template-plan.md](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/docs/city-based-diy-template-plan.md))。
|
||||
|
||||
后端由另一名同事改造完成,新增了 `vr_ticket/geo/city` 接口:
|
||||
```bash
|
||||
curl -X POST 'http://localhost:10000/api.php?s=plugins/index&pluginsname=vr_ticket&pluginscontrol=geo&pluginsaction=city' \
|
||||
-H 'Content-Type: application/json' \
|
||||
-d '{"lng": 118.110, "lat": 24.490}'
|
||||
|
||||
# 成功:{"msg":"success","code":0,"data":{"city":"厦门市","city_id":150,"distance":2.43,...}}
|
||||
# 越界(>150km):{"msg":"当前位置暂无服务城市(最近 厦门市 约 4039.75km)","code":-1,"data":""}
|
||||
```

||||
|
||||
后端 API 假定请求 URL 里有 `user_lng` / `user_lat` 坐标参数时会自动按距离匹配最近城市并返回对应 DIY 模板。
|
||||
|
||||
本次任务:**在前端实现"用户进首页自动获取位置 + 反查城市 + 同步显示到左上角位置选择器 + 重新请求首页让后端按坐标推荐模板"**。
|
||||
|
||||
---
|
||||
|
||||
## 二、问题经过
|
||||
|
||||
### 2.1 阶段一:DIY 首页左上角"位置选择器"在自动获取坐标后不更新
|
||||
|
||||
**现象**:DIY 首页 `onLoad` 会调 `app.globalData.get_user_location()` 异步获取位置,但 `choice-location` 组件仅在 `created` 钩子读一次 storage,**不监听 storage 变化**。结果是:用户授权后 storage 写入了坐标,但 UI 文本仍是初始空状态。
|
||||
|
||||
**修复**:在 `choice-location` 组件加 `watch_auto_location()` 轮询 storage,500ms 检测 `status == 1` 立即 setData,并 `console.log` 便于确认。
|
||||
|
||||
### 2.2 阶段二:自动获取到的位置只显示"当前位置",没有城市名
|
||||
|
||||
**现象**:storage 写入的 `name: i18n.t('shopxo-uniapp.app.tghyu3')` = "当前位置"(占位字符串)。
|
||||
|
||||
**调研**:
|
||||
1. 搜索"geocode" / "city by coordinate" 类 JS 库
|
||||
2. 考虑过 `offline-geocode-city` 等离线方案
|
||||
3. 用户明确建议:**"边界处找错城市没关系,后端会自动根据坐标判断最接近的城市中心点"**
|
||||
|
||||
**最终方案**:用后端 `vr_ticket/geo/city` 接口(成熟方案,已在 VR Ticket 插件中被使用)。在 `watch_auto_location` 命中 `status:1` 后立即调 `fetch_city_by_coordinate(lat, lng)` 反查,合并到 `location.name / location.text`。
|
||||
|
||||
**配套安全机制**:
|
||||
- 失败 / 越界(`code != 0`)静默降级为"当前位置"
|
||||
- 加 `_is_destroyed` 守卫防止异步回调对已卸载组件 setData
|
||||
- 通过 `app.globalData.get_request_url('city', 'geo', 'vr_ticket')` 复用项目标准接口封装
|
||||
|
||||
**验证日志**(用户提供):
|
||||
```
|
||||
[ChoiceLocation] auto location ready: {name: "当前位置", address: null, lat: 24.57591, lng: 118.09728, text: "当前位置"}
|
||||
[ChoiceLocation] city resolved: {city: "厦门市", city_id: 150, distance: 10.75}
|
||||
```
|
||||
✅ 成功:UI 文本从"当前位置"切换为"厦门市"。
|
||||
|
||||
### 2.3 阶段三:第二次进 DIY 首页完全没动静
|
||||
|
||||
**现象**:用户首次授权后,再次进入 DIY 首页,`get_user_location` 没有重新调用,`watch_auto_location` 不触发。
|
||||
|
||||
**根因分析**:深入 [App.vue:3100-3173](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/App.vue#L3100-L3173) 的 `get_user_location`:
|
||||
|
||||
```javascript
|
||||
get_user_location(object = null, method = null, is_force = false) {
|
||||
if(this.data.get_user_location_status == 1 || is_force) {
|
||||
var cache_key = this.data.cache_userlocation_key;
|
||||
var result = uni.getStorageSync(cache_key) || null;
|
||||
if(result == null) { // ← 第二次进入时 storage 已有值,整个 if 块被跳过
|
||||
// 启动 setInterval 调 uni.getLocation
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- `result == null` 守护的本意:避免重复弹权限
|
||||
- 副作用:**已授权用户后续再进首页永远不会重新获取位置**
|
||||
- **附加 bug**:`uni.getLocation` 没有 `fail` 回调,权限拒绝后 status 永远停在旧值或 null,**会无限重弹**
|
||||
|
||||
**用户决策**:
|
||||
- 过期阈值:**5 分钟**("已授权用户基本不会重弹")
|
||||
- 重新请求首页:拿到新坐标后直接重发 `init()`,后端会按坐标自动判断返回哪个 DIY 模板
|
||||
|
||||
**修复方案**:
|
||||
1. `get_user_location` 加入 5 条件守护(5 分钟过期 + name 占位判定 + status != 1 + 无缓存 + is_force)
|
||||
2. 写入 storage 加 `updated_at: Date.now()` 时间戳
|
||||
3. 成功时 `uni.$emit('onLocationReady', address)` 通知订阅方
|
||||
4. **新增 fail 回调**:写入 `status:0` 占位,避免无限重弹(修复隐藏 bug)
|
||||
5. `pages/index/index.vue` 监听 `onLocationReady` → 调 `init({is_cache:0, loading:1})` 重新请求首页
|
||||
6. `choice-location.vue` 监听 `onLocationReady` → 仅当 `name == '当前位置'` 占位时才重新反查
|
||||
|
||||

|
||||
|
||||
## 三、技术调研与决策
|
||||
|
||||
### 3.1 为什么不用离线 geocode 库
|
||||
|
||||
| 库 | 问题 |
|
||||
|---|---|
|
||||
| `offline-geocode-city` | 体积大、多年未维护、坐标边界匹配误差大 |
|
||||
| `coordtransform` | 只做坐标系转换,不做城市反查 |
|
||||
| 高德/腾讯地图 SDK | 需要 API key、增加包体积、跨端统一麻烦 |
|
||||
|
||||
**最终选择**:后端 `vr_ticket/geo/city`。理由:
|
||||
1. 跨端一致(H5/小程序/APP 同结果)
|
||||
2. 零前端依赖
|
||||
3. 距离匹配已优化(VR Ticket 插件在用)
|
||||
4. 业务数据(城市中心点)由后端维护
|
||||
|
||||
### 3.2 为什么用 `uni.$emit/on` 事件
|
||||
|
||||
- 项目里已有先例([pages/plugins/distribution/recommend-list/recommend-list.vue:102](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/pages/plugins/distribution/recommend-list/recommend-list.vue#L102) `uni.$on('refresh')`)
|
||||
- 解耦:`App.vue` 只负责"拿位置",不感知具体页面
|
||||
- `index.vue` 和 `choice-location` 各自 `uni.$on` 同一事件,互不影响
|
||||
- `onUnload` / `beforeDestroy` 里 `uni.$off` 清理
|
||||
|
||||
### 3.3 `init({is_cache:0, loading:1})` 的细节
|
||||
|
||||
- `is_cache: 0` → 强制走远端,不读前端缓存
|
||||
- `loading: 1` → 跳过 `#ifdef APP` 的网络检查
|
||||
- 由于 `load_status == 1`(已成功加载过),不会显示 loading 层
|
||||
- `request_params_handle` 会自动把 `user_lng` / `user_lat` 拼进 URL,后端按新坐标推荐
|
||||
|
||||
### 3.4 重新请求 `get_user_location` 的安全性
|
||||
|
||||
**注意 [weixin-location-permission.md:192](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/docs/troubleshoot/weixin-location-permission.md#L192) 的警告**:
|
||||
|
||||
> 5. 不要重写 `App.vue:get_user_location`——原代码 setInterval 等待是**故意设计**的,避免协议未同意就 fail 导致 navigateTo 死循环
|
||||
|
||||
**本次重写严格遵守**该原则的核心理念:
|
||||
- ✅ **保留了**原 setInterval 流程([App.vue:3144-3210](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/App.vue#L3144-L3210))—— 包含微信隐私协议 / APP 网络检查
|
||||
- ✅ **没有**在 fail 时 navigateTo —— 只是写 `status:0` 占位 + 触发事件
|
||||
- ⚠️ **打破了**"不要重写"的字面建议 —— 但**没有**引入原警告里描述的"弹窗栈式累积"风险
|
||||
|
||||
原警告的"重写"指的是「改成 3 状态流程 + fail 时 navigateTo」那种激进重构;本次重写**仅扩展守护条件 + 修正 fail 回调 + 加事件通知**,是**最小侵入**的扩展。
|
||||
|
||||
### 3.5 兼容性分析
|
||||
|
||||
#### `get_user_location` 签名变化
|
||||
| 项 | 原版 | 新版 | 兼容? |
|
||||
|---|---|---|---|
|
||||
| 函数签名 | `get_user_location(object, method, is_force)` | 完全相同 | ✅ |
|
||||
| 回调接口 | `object[method](address)` | 完全相同 | ✅ |
|
||||
| storage 键 | `cache_userlocation_key` | 完全相同 | ✅ |
|
||||
| storage 字段 | `{name, address, lat, lng, status}` | + `updated_at` | ✅ 向后兼容 |
|
||||
|
||||
#### 唯一显式调用方
|
||||
[realstore/index/index.vue:308](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/pages/plugins/realstore/index/index.vue#L308):
|
||||
```javascript
|
||||
app.globalData.get_user_location(this, 'user_back_auto_location', true);
|
||||
```
|
||||
- `is_force=true` → `need_refresh = true` → 启动 setInterval → success 后回调 `user_back_auto_location`
|
||||
- **完全兼容**
|
||||
|
||||
#### `choice-location` 组件的 8 个使用点
|
||||
| 位置 | 影响 |
|
||||
|---|---|
|
||||
| `pages/index/index.vue` (普通首页) | 正面:UI 显示更准 |
|
||||
| `pages/diy/components/diy/header.vue` | **正面:DIY 首页核心场景** |
|
||||
| `pages/diy/components/diy/search.vue` | 正面:DIY 搜索框 |
|
||||
| `pages/user-address-save/user-address-save.vue` | 中性:用户主动选地址后才进 |
|
||||
| `pages/plugins/realstore/index/index.vue` | 正面:门店按城市筛更准 |
|
||||
| `pages/plugins/realstore/search/search.vue` | 正面 |
|
||||
| `pages/plugins/distribution/extraction-switch/extraction-switch.vue` | 正面 |
|
||||
| `pages/plugins/distribution/extraction-apply/extraction-apply.vue` | 正面 |
|
||||
|
||||
**关键安全保证**:`on_global_location_ready` **仅当** `name == '当前位置'` 占位时才会反查。如果该实例已经被用户手动选过具体地址(如 `user-address-save`),`name` 不是占位,**完全跳过**。
|
||||

||||
|
||||
## 四、最终数据流
|
||||
|
||||
```
|
||||
DIY 首页 onLoad
|
||||
└→ app.globalData.page_event_onload_handle(params)
|
||||
└→ this.get_user_location()
|
||||
├─ 守护条件判定(5 分钟过期 / 占位 name / status != 1 / 无缓存 / is_force)
|
||||
│ ├─ 不需要刷新 → return(已授权且 5 分钟内已成功获取过)
|
||||
│ └─ 需要刷新 → setInterval 启动
|
||||
│ ├─ 微信环境:等隐私协议 (uni.getPrivacySetting)
|
||||
│ ├─ APP 环境:等网络 (uni.getNetworkType)
|
||||
│ └─ uni.getLocation
|
||||
│ ├─ success → 写 storage {lat, lng, status:1, updated_at: now}
|
||||
│ │ → uni.$emit('onLocationReady', address)
|
||||
│ │ ├─ pages/index/index.vue → on_location_ready_handle
|
||||
│ │ │ └─ init({is_cache:0, loading:1}) → 后端按新坐标推荐
|
||||
│ │ └─ components/choice-location → on_global_location_ready
|
||||
│ │ └─ 仅当 name 是占位时 fetch_city_by_coordinate
|
||||
│ │ └─ 后端 /vr_ticket/geo/city → 合并 name='厦门市'
|
||||
│ └─ fail → 写 storage {status:0, updated_at: now}
|
||||
│ → uni.$emit('onLocationReady', failed) // 通知重发请求
|
||||
│ └─ pages/index/index.vue → init() 重新请求
|

## 七、给未来 Agent 的提醒
|
||||
|
||||
如果你在这个项目上做位置 / 城市相关工作:
|
||||
|
||||
1. **`App.vue:get_user_location` 的 5 条件守护**(5 分钟过期 + 占位 + status + 无缓存 + is_force)已经在 2026-06-28 重构。**不要在没读这个文档的情况下再改守护条件**。
|
||||
2. **`onLocationReady` 事件**是 2026-06-28 新增的全局事件,被 `pages/index/index.vue` 和 `components/choice-location/choice-location.vue` 订阅。如果要再加订阅方,记得在 `onUnload` / `beforeDestroy` 里 `uni.$off` 清理。
|
||||
3. **choice-location 组件的反查是惰性的**——仅当 `name == '当前位置'` 占位时才调 `/vr_ticket/geo/city`。如果该实例已经被用户手动选过具体地址,反查会被跳过。
|
||||
4. **`init({is_cache:0, loading:1})` 是重新请求首页的标准写法**。`request_params_handle` 会自动带 `user_lng` / `user_lat`,后端按坐标推荐。
|
||||
5. **不要破坏原 setInterval 流程**——微信隐私协议 / APP 网络检查是必需的。如果要重写 `get_user_location`,必须保留这两个 `#ifdef` 分支。
|
||||
6. **`__usePrivacyCheck__` 在 manifest.json** 仍然按 [weixin-location-permission.md](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/docs/troubleshoot/weixin-location-permission.md) 文档保持 `false`(直到后台审核通过)。

3. 看到 errno 112 → 第一反应是隐私指引配置问题,**不要瞎改业务代码**

4. modal-business.init 的调用链路依赖 App.vue 的 `is_config` 轮询,**本地无后端时不会触发**——但只要 `__usePrivacyCheck__: false`,这个不影响 `uni.getLocation` 的工作
|
||||
5. 不要重写 `App.vue:get_user_location`——原代码 setInterval 等待是**故意设计**的,避免协议未同意就 fail 导致 navigateTo 死循环

## 八、文档更新历史
|
||||
|
||||
### 2026-06-28 部分修正
|
||||
|
||||
**关于 §七.5 "不要重写 `App.vue:get_user_location`"**:
|
||||
|
||||
> ⚠️ **本条警告的字面建议已被打破**,但核心理念仍有效。详情见 [diy-home-location-work-record-20260628.md §3.4](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/docs/diy-home-location-work-record-20260628.md)。
|
||||
|
||||
**修正点**:
|
||||
- 2026-06-28 的 [diy-home-location-work-record-20260628.md](file:///Users/bigemon/WorkSpace/vr-shopxo-uniapp/docs/diy-home-location-work-record-20260628.md) 对 `get_user_location` 做了**最小侵入扩展**(不是 §四.3 提到的"3 状态流程"那种激进重构):
|
||||
- 守护条件从"无缓存才获取"扩展为"5 条件 OR 判定"(5 分钟过期 + 占位 + status + 无缓存 + is_force)
|
||||
- 写入 storage 加 `updated_at: Date.now()` 时间戳
|
||||
- 成功时 `uni.$emit('onLocationReady', address)` 通知订阅方
|
||||
- **新增 fail 回调**:写 `status:0` 占位 + 触发事件,**修复**了 §四中提到的"权限拒绝后无限重弹"的隐藏 bug
|
||||
- **核心理念仍然有效**(必须保留):
|
||||
- ✅ setInterval 等待微信隐私协议 / APP 网络检查
|
||||
- ✅ 不得在 fail 时 navigateTo 到 open-setting-location 页面(避免与 setInterval 形成死循环)
|
||||
- ✅ 不得改写 `uni.getLocation` 调用本身的参数
|
||||
|
||||
**如果你要在 `get_user_location` 上做扩展**:
|
||||
- 必须保留 setInterval 流程和 `#ifdef MP-WEIXIN` / `#ifdef APP` 分支
|
||||
- fail 回调**只能**写 storage + 触发事件,**绝对不能** navigateTo / switchTab / reLaunch

||||
