说明：

没有进房间，没有推流，调用预览api后本地可以看到视频，再截图，截图走到success回调，但是没有返回截图的临时路径

代码片段：

const wx_pusher = wx.createLivePusherContext("wx_pusher")

// 先调用预览，本地可以看到视频
wx_pusher.startPreview({
    success: function () {
      resolve()
    },
    fail: function (err) {
      reject(err);
    }
})

// 预览成功后，截图
wx_pusher.snapshot({
  quality: 'compressed',
  sourceType: 'view',
  complete:(e)=>{
    if (e.tempImagePath) {
      resolve(e) 
      // 鸿蒙系统返回 {"errno":0,"errMsg":"operateXWebLivePusher:ok"}
      // 正常手机返回 {"errno":0,"tempImagePath":"","width":xx,"height":xx}
    } else {
      reject(e)
    }
 }
})
