## 🎯 技术方案
|
||
|

### 最终方案:iframe 嵌套方案
|
||
|
||
```
|
||
Vue 组件 → web-view → 本地HTML → 萤石云 iframe
|
||
```

## 🐛 遇到的问题与解决
|
||
|
||
### 问题 1:APP 中看不到监控画面(黑屏)
|
||
|
||
**现象:**
|
||
- H5 正常显示
|
||
- APP 打包后一直显示"正在加载萤石云播放器..."
|
||
|
||
**原因:**
|
||
- `web-view` 尝试加载的 `/static/html/ezviz-player.html` 文件不存在
|
||
|
||
**解决方案:**
|
||
```javascript
|
||
// ✅ 创建本地 HTML 文件
|
||
/static/html/ezviz-iframe.html
|
||
|
||
// ✅ 在 web-view 中正确引用
|
||
this.webviewUrl = `/static/html/ezviz-iframe.html?accessToken=${token}&playUrl=${url}`
|
||
```
|
||
|
||
---
|
||
|
||
### 问题 2:APP 闪退(OutOfMemoryError)
|
||
|
||
**现象:**
|
||
```
|
||
FATAL EXCEPTION: main
|
||
java.lang.OutOfMemoryError: Failed to allocate a 268435468 byte allocation with 25165824 free bytes
|
||
```
|
||
|
||
**原因:**
|
||
- 最初尝试加载完整的 EZUIKit.js SDK(~20MB)
|
||
- 默认 APP 内存限制(256MB)不够
|
||
|
||
**尝试的方案:**
|
||
|
||
#### 方案 A:增加 APP 内存(失败)
|
||
```json
|
||
// manifest.json
|
||
"compatible": {
|
||
"largeHeap": true // 增加到 512MB,但仍然崩溃
|
||
}
|
||
```
|
||
|
||
#### 方案 B:延迟加载 SDK(失败)
|
||
```javascript
|
||
// 动态加载 SDK,延迟1秒
|
||
setTimeout(() => {
|
||
loadSDK()
|
||
}, 1000)
|
||
```
|
||
|
||
#### ✅ 方案 C:使用 iframe 播放器(成功)
|
||
```javascript
|
||
// 直接嵌入萤石云官方 iframe,不加载本地 SDK
|
||
const iframeUrl = 'https://open.ys7.com/ezopen/h5/iframe?' +
|
||
'url=' + encodeURIComponent(playUrl) +
|
||
'&accessToken=' + encodeURIComponent(accessToken)
|
||
```
|
||
|
||
**最终解决:**
|
||
- ✅ 使用萤石云官方 iframe 播放器
|
||
- ✅ 避免加载本地 SDK
|
||
- ✅ 内存占用降低 90%
|
||
- ✅ 稳定运行,不再崩溃
|

||
|
||
### 问题 3:画面变形(拉伸)
|
||
|
||
**现象:**
|
||
- 监控画面铺满全屏,导致画面拉伸变形
|
||
|
||
**原因:**
|
||
- 容器高度设置为 `100vh`,不保持宽高比
|
||
|
||
**解决方案:**
|
||
```scss
|
||
/* 使用 padding-top 技巧保持 16:9 宽高比 */
|
||
.video-content {
|
||
width: 100%;
|
||
position: relative;
|
||
|
||
/* 关键:使用伪元素创建固定宽高比 */
|
||
&::before {
|
||
content: '';
|
||
display: block;
|
||
padding-top: 56.25%; /* 16:9 = 9/16 = 56.25% */
|
||
}
|
||
|
||
/* 播放器绝对定位填充容器 */
|
||
:deep(.simple-video-player) {
|
||
position: absolute;
|
||
top: 0;
|
||
left: 0;
|
||
width: 100%;
|
||
height: 100%;
|
||
}
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
### 问题 4:组件引用错误
|
||
|
||
**现象:**
|
||
```javascript
|
||
Uncaught TypeError: Cannot read properties of undefined (reading 'initEzuikit')
|
||
```
|
||
|
||
**原因:**
|
||
- 执行顺序错误,组件还未渲染就尝试调用方法
|
||
|
||
**错误代码:**
|
||
```javascript
|
||
// ❌ 错误顺序
|
||
this.$nextTick(() => {
|
||
this.$refs.playerVideoRef.initEzuikit(config) // ref 不存在
|
||
})
|
||
this.ezstate = true // 这时才开始渲染组件
|
||
```
|
||
|
||
**正确代码:**
|
||
```javascript
|
||
// ✅ 正确顺序
|
||
// 1. 先让组件渲染
|
||
this.ezstate = true
|
||
|
||
// 2. 等待 DOM 更新
|
||
await this.$nextTick()
|
||
|
||
// 3. 安全调用
|
||
if (this.$refs.playerVideoRef) {
|
||
this.$refs.playerVideoRef.initEzuikit(config)
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
### 问题 5:横屏展示需求
|
||
|
||
**需求:**
|
||
- 监控页面需要横屏展示
|
||
- 其他页面保持竖屏
|
||
|
||
**解决方案:**
|
||
```json
|
||
// pages.json - 只设置监控页面为横屏
|
||
{
|
||
"path": "pages/visual/index",
|
||
"style": {
|
||
"navigationBarTitleText": "移动式检修车间",
|
||
"navigationStyle": "custom",
|
||
"pageOrientation": "landscape" // ← 关键配置
|
||
}
|
||
}
|
||
```
|
||
|
||

|
||
|
||
## ✅ 最终实现

|
||
|
||
## 📦 部署清单
|
||
|
||
### 必需文件
|
||
|
||
```
|
||
✅ src/pages/visual/index.vue # 监控页面
|
||
✅ src/components/EzvizVideoPlayerSimple.vue # 播放器组件
|
||
✅ src/static/html/ezviz-iframe.html # iframe HTML
|
||
✅ src/utils/ezvizTokenManager.js # Token管理
|
||
✅ src/utils/ezvizDeviceChecker.js # 设备检查
|
||
```
|
||
|
||
### 配置文件
|
||
|
||
```
|
||
✅ src/pages.json # 页面配置(横屏)
|
||
✅ src/manifest.json # APP配置(内存)
|
||
```
|
||
|
||
### 萤石云账号信息
|
||
|
||
```
|
||
✅ AppKey: your-app-key
|
||
✅ AppSecret: your-app-secret
|
||
✅ 设备序列号: K74237657
|
||
✅ 验证码: (设备标签上)
|
||
```
|
||
|
||
---
|
||
|
||
## 🎯 最佳实践
|
||
|
||
### 1. AccessToken 管理
|
||
|
||
```javascript
|
||
// ✅ 推荐:使用自动管理
|
||
const accessToken = await tokenManager.getValidAccessToken()
|
||
|
||
// ❌ 不推荐:硬编码
|
||
const accessToken = "at.xxx..." // 2小时后过期
|
||
```
|
||
|
||
---
|
||
|
||
### 2. 错误处理
|
||
|
||
```javascript
|
||
try {
|
||
const accessToken = await tokenManager.getValidAccessToken()
|
||
this.$refs.playerVideoRef.initEzuikit({
|
||
accessToken,
|
||
play_url: 'ezopen://...'
|
||
})
|
||
} catch (error) {
|
||
console.error('播放器初始化失败:', error)
|
||
|
||
uni.showToast({
|
||
title: '加载失败,请重试',
|
||
icon: 'error'
|
||
})
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
### 3. 组件生命周期
|
||
|
||
```javascript
|
||
export default {
|
||
onLoad() {
|
||
// 页面加载时初始化
|
||
this.getVideoData()
|
||
},
|
||
onShow() {
|
||
// 页面显示时刷新(可选)
|
||
// this.getVideoData()
|
||
},
|
||
onHide() {
|
||
// 页面隐藏时可以停止播放(节省流量)
|
||
}
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
### 4. 性能优化
|
||
|
||
```javascript
|
||
// ✅ 使用 $nextTick 确保 DOM 更新
|
||
this.ezstate = true
|
||
await this.$nextTick()
|
||
this.$refs.playerVideoRef.initEzuikit(config)
|
||
|
||
// ✅ 销毁时清理资源
|
||
onUnload() {
|
||
this.ezstate = false
|
||
}
|
||
|
||
// ✅ 切换清晰度(标清更省流量)
|
||
play_url: "ezopen://open.ys7.com/K74237657/1.sd.live"
|
||
```
|
||
|
||
---
|
||
|
||
## ❓ 常见问题
|
||
|
||
### Q1: 视频加载很慢或黑屏?
|
||
|
||
**排查步骤:**
|
||
1. ✅ 检查网络连接
|
||
2. ✅ 验证 AccessToken 是否有效
|
||
3. ✅ 确认设备是否在线
|
||
4. ✅ 尝试切换清晰度(hd → sd)
|
||
5. ✅ 查看控制台日志
|
||
|
||
**解决方法:**
|
||
```javascript
|
||
// 检查 AccessToken
|
||
console.log('AccessToken:', accessToken.substring(0, 20))
|
||
|
||
// 检查播放地址
|
||
console.log('PlayUrl:', play_url)
|
||
|
||
// 检查 iframe URL
|
||
console.log('iframeUrl:', iframeUrl)
|
||
```
|
||
|
||
---
|
||
|
||
### Q2: 如何调试 web-view?
|
||
|
||
**方法1:使用 console.log**
|
||
```javascript
|
||
// HTML 中的日志会显示在 APP 控制台
|
||
console.log('[iframe] 初始化完成')
|
||
```
|
||
|
||
**方法2:Chrome Remote Debugging(推荐)**
|
||
```bash
|
||
# 1. 连接设备
|
||
adb devices
|
||
|
||
# 2. 在 Chrome 中打开
|
||
chrome://inspect/#devices
|
||
|
||
# 3. 找到 web-view 进程并点击 inspect
|
||
```
|
||
|
||
**方法3:BlueStacks 日志**
|
||
```bash
|
||
adb logcat | grep -i "chromium\|console"
|
||
```
|
||
|
||
---
|
||
|
||
### Q3: AccessToken 过期怎么办?
|
||
|
||
**自动续期(推荐):**
|
||
```javascript
|
||
// tokenManager 会自动检查并刷新
|
||
const accessToken = await tokenManager.getValidAccessToken()
|
||
```
|
||
|
||
**手动刷新:**
|
||
```javascript
|
||
// 清除缓存,下次会重新获取
|
||
uni.removeStorageSync('ezviz_access_token')
|
||
uni.removeStorageSync('ezviz_token_expire')
|
||
```
|
||
|
||
---
|
||
|
||
### Q4: 如何切换摄像头?
|
||
|
||
```javascript
|
||
// 修改 play_url
|
||
const play_url = "ezopen://open.ys7.com/另一个设备序列号/1.hd.live"
|
||
|
||
// 重新初始化
|
||
this.$refs.playerVideoRef.initEzuikit({
|
||
accessToken,
|
||
play_url
|
||
})
|
||
```
|
||
|
||
---
|
||
|
||
### Q5: 如何同时播放多个摄像头?
|
||
|
||
```vue
|
||
<template>
|
||
<view>
|
||
<!-- 摄像头1 -->
|
||
<EzvizVideoPlayer ref="player1"></EzvizVideoPlayer>
|
||
|
||
<!-- 摄像头2 -->
|
||
<EzvizVideoPlayer ref="player2"></EzvizVideoPlayer>
|
||
</view>
|
||
</template>
|
||
|
||
<script>
|
||
export default {
|
||
methods: {
|
||
async loadAllCameras() {
|
||
const accessToken = await tokenManager.getValidAccessToken()
|
||
|
||
// 初始化摄像头1
|
||
this.$refs.player1.initEzuikit({
|
||
accessToken,
|
||
play_url: "ezopen://open.ys7.com/K74237657/1.hd.live"
|
||
})
|
||
|
||
// 初始化摄像头2
|
||
this.$refs.player2.initEzuikit({
|
||
accessToken,
|
||
play_url: "ezopen://open.ys7.com/K74237658/1.hd.live"
|
||
})
|
||
}
|
||
}
|
||
}
|
||
</script>
|
||
```
|
||
|
||
---
|
||
|
||
### Q6: 如何实现录像功能?
|
||
|
||
萤石云官方 iframe 播放器自带录像功能,只需启用控制条:
|
||
|
||
```javascript
|
||
const iframeUrl = 'https://open.ys7.com/ezopen/h5/iframe?' +
|
||
'url=' + encodeURIComponent(playUrl) +
|
||
'&accessToken=' + encodeURIComponent(accessToken) +
|
||
'&controls=1' // ← 显示控制条,包含录像按钮
|
||
```
|
||
|
||
---
|
||
|
||
### Q7: 内存占用还是太高怎么办?
|
||
|
||
**优化建议:**
|
||
|
||
1. **降低清晰度**
|
||
```javascript
|
||
play_url: "ezopen://open.ys7.com/K74237657/1.sd.live" // 标清
|
||
```
|
||
|
||
2. **限制同时播放数量**
|
||
```javascript
|
||
// 一次只播放一个摄像头
|
||
if (this.currentPlayer) {
|
||
this.currentPlayer.refresh() // 先停止当前播放
|
||
}
|
||
```
|
||
|
||
3. **页面切换时停止播放**
|
||
```javascript
|
||
onHide() {
|
||
this.ezstate = false // 停止播放
|
||
}
|
||
```
|
||
