小程序钉钉语音录入组件

前言

本文章的代码，主要针对于钉钉上小程序的开发，实现语音录入转化为文本的功能。如有什么问题欢迎留言交流。

注意：
本功能只有钉钉Version4.6.5以后的版本才支持，目前钉钉的小程序开发工具v0.26.0-beta.3版本上暂时不支持此功能，会导致报错。需要将本代码有关语音的部分注释掉，当在真机上预览或发布的时候放开注释掉的代码即可。我相信后续钉钉应该会完善对应的支持，如果你的版本已经支持，无需看本条提示。

代码效果

引入组件的页面

//.axml页面
//使用组件
<speech label="备注(可选)" keyName="remarks"  placeholder="请按住语音图片录入语音..." maxlength="100" onChange="onChange"/>

//.json页面
{
  "usingComponents": {//引用speech组件
    "speech": "/component/speech/speech",
  }
}
