Camera

调用系统相机，该组件是原生组件，使用时请注意相关限制。扫码二维码功能需要将微信客户端升级到6.7.3并且需要用户授权，其属性如下：

示例代码如下：

<camera device-position='back' flash="off" binderror='error' style='width:100%;height:300px;'>
</camera>
<button type='primary' bindtap='takePhoto'>拍照</button>
<view>预览</view>
<image mode='widthFix' src='{{src}}'></image>

Page({
  takePhoto(){
    const ctx =wx.createCameraContext()
    ctx.takePhoto({
      quality:'high',
      success:(res)=>{
        this.setData({
          src:res.tempImagePath
        })
      }
    })
  },
  error(e){
    console.log(e.detail)
  }
})

执行结果如下：

live-player

实时音视频播放。该组件是原生组件，使用时请注意相关限制。暂只针对国内主体如下类目的小程序开放，需要先通过类目审核，再在小程序管理后台，「开发」-「接口设置」中自助开通该组件权限。请参考微信官方相关文档：
