        $data = $this->request()->getRequestParam();

引入axios

//数据
      getMp3Data(){
        //现在
        //recorder.downloadWAV('xz');
        let mp3Name = 'audio_recording_' + new Date().getTime()+'.wav';
        console.log(mp3Name)
        let blob = recorder.getWAVBlob();
        let formData = new FormData();
        formData.append('file', blob);
        formData.append("namedademav", mp3Name);
        let instance = axios.create({
          headers: {
            'Content-Type': 'multipart/form-data'
          }
        })
        let contentType = "application/json";
        instance.post('http://域名:9501/Common/img', formData).then(res => {
          console.log('res---', res)
        })


      },
