#微信JSSDK Promise版本 微信JSSDK使用回调函数进行异步处理，但是某些接口会存在“回调嵌套”的问题，比如【播放一个服务器的录音文件】，需要：

1. wx.downloadVoice
2. wx.playVoice 本程序对微信JSSDK进行的一层Promise包装，配合ES7的async/await可以解决此类问题 ##注意
3. 本程序依旧依赖微信JSSDK的js，请提前加载
4. 微信原始JSSDK中的方法依旧可以使用
   ##异步接口

• wx.config => wx.configAsync
• wx.checkJsApi => wx.checkJsApiAsync
• wx.onMenuShareTimeline => wx.onMenuShareTimelineAsync
• wx.onMenuShareQQ => wx.onMenuShareQQAsync
• wx.onMenuShareWeibo => wx.onMenuShareWeiboAsync
• wx.onMenuShareQZone => wx.onMenuShareQZoneAsync
• wx.chooseImage => wx.chooseImageAsync
• wx.previewImage => wx.previewImageAsync
• wx.uploadImage => wx.uploadImageAsync
• wx.downloadImage => wx.downloadImageAsync
• wx.startRecord => wx.startRecordAsync
• wx.stopRecord => wx.stopRecordAsync
• wx.onVoiceRecordEnd => wx.onVoiceRecordEndAsync
• wx.playVoice => wx.playVoiceAsync
• wx.pauseVoice => wx.pauseVoiceAsync
• wx.stopVoice => wx.stopVoiceAsync
• wx.onVoicePlayEnd => wx.onVoicePlayEndAsync
• wx.uploadVoice => wx.uploadVoiceAsync
• wx.downloadVoice => wx.downloadVoiceAsync
• wx.translateVoice => wx.translateVoiceAsync
• wx.getNetworkType => wx.getNetworkTypeAsync
• wx.getLocation => wx.getLocationAsync
• wx.startSearchBeacons => wx.startSearchBeaconsAsync
• wx.stopSearchBeacons => wx.stopSearchBeaconsAsync
• wx.onSearchBeacons => wx.onSearchBeaconsAsync
• wx.scanQRCode => wx.scanQRCodeAsync
• wx.chooseCard => wx.chooseCardAsync
• wx.addCard => wx.addCardAsync
• wx.chooseWXPay => wx.chooseWXPayAsync ##使用方法
  以 wx.chooseImage 为例

//使用wx.config
wx.config({
  //...
});
wx.ready(function() {
  //ready
});
wx.error(function(res) {
  //error
});
//可以看到非常繁琐
//使用wx.configAsyn
async function config() {
  try{
    await wx.configAsync({
      //...
    });
  }catch (e){
    //console.error(e.message);    
  }
}
