小程序实现录音上传

首先我们先看一下微信小程序的API

https://developers.weixin.qq.com/miniprogram/dev/api/getRecorderManager.html?search-key=%E5%BD%95%E9%9F%B3

这里有关于小程序录音的一些基本配置，

index.wxml:

<view class='progress_box' bindtap='openRecording' style="display:{{openRecordingdis}}">
        <view class="progress_bgs">
          <view class="progress_bg">
            <image class="progress_img" src='../../../images/SubjectInformation/luyin.png'></image>
          </view>
        </view>
      </view>

index.wxss:

.topicRecording {
  float: left;
  width: 40%;
  height: 100%;
  position: relative;
}


.progress_box {
  width: 130rpx;
  height: 130rpx;
  margin-left: -65rpx;
  position: absolute;
  bottom: 0;
  left: 50%;
  display: flex;
  align-items: center;
  justify-content: center;
  background: #ccc;
  border-radius: 50%;
}

.progress_bgs {
  width: 114rpx;
  height: 114rpx;
  background: #fff;
  border-radius: 50%;
  margin: 9rpx;
}


.progress_bg {
  width: 106rpx;
  height: 106rpx;
  margin: 5rpx;
  position: absolute;
  background: #444;
  border-radius: 50%;
}



.progress_img {
  width: 82rpx;
  height: 82rpx;
  border-radius: 50%;
  margin: 12rpx;
}

 index.js:

Page({
  data: {
    openRecordingdis: "block",//录音图片的不同
    shutRecordingdis: "none",//录音图片的不同
    recordingTimeqwe:0,//录音计时
    setInter:""//录音名称
  },

   //录音计时器
  recordingTimer:function(){
    var that = this;
    //将计时器赋值给setInter
    that.data.setInter = setInterval(
      function () {
        var time = that.data.recordingTimeqwe + 1;
        that.setData({
          recordingTimeqwe: time
        })
      }
      , 1000); 
  },


  //开始录音
  openRecording: function() {
    var that = this;
    wx.getSystemInfo({
      success: function(res) {
        that.setData({
          shutRecordingdis: "block",
          openRecordingdis: "none"
        })
      }
    })
    const options = {
      duration: 60000, //指定录音的时长，单位 ms，最大为10分钟（600000），默认为1分钟（60000）
      sampleRate: 16000, //采样率
      numberOfChannels: 1, //录音通道数
      encodeBitRate: 96000, //编码码率
      format: 'mp3', //音频格式，有效值 aac/mp3
      frameSize: 50, //指定帧大小，单位 KB
    }
    //开始录音计时   
    that.recordingTimer();
    //开始录音
    recorderManager.start(options);
    recorderManager.onStart(() => {
      console.log('。。。开始录音。。。')
    });
    //错误回调
    recorderManager.onError((res) => {
      console.log(res);
    })
  },

  //结束录音
  shutRecording: function() {
    var that = this;
    wx.getSystemInfo({
      success: function(res) {
        that.setData({
          shutRecordingdis: "none",
          openRecordingdis: "block"
        })
      }
    })
    recorderManager.stop();
    recorderManager.onStop((res) => {
      console.log('。。停止录音。。', res.tempFilePath)
      const {tempFilePath} = res;
      //结束录音计时  
      clearInterval(that.data.setInter);
      //上传录音
      wx.uploadFile({
        url: appURL + '/wx_SubjectInformation/wx_SubjectRecordKeeping.do',//这是你自己后台的连接
        filePath: tempFilePath,
        name:"file",//后台要绑定的名称
        header: {
          "Content-Type": "multipart/form-data"
        },
        //参数绑定
        formData:{
          recordingtime: that.data.recordingTimeqwe,

        },
        success:function(ress){
          console.log(res);
          wx.showToast({
            title: '保存完成',
            icon:'success',
            duration:2000
          })
        },
        fail: function(ress){
          console.log("。。录音保存失败。。");
        }
      })
    })
  },

  //录音播放
  recordingAndPlaying: function(eve) {
    wx.playBackgroundAudio({
      //播放地址
      dataUrl: '' + eve.currentTarget.dataset.gid + ''
    })
  },

})

 上传服务

@RequestMapping(value = "/wx_SubjectRecordKeeping", produces = "application/json")
	@ResponseBody
	public Object wx_SubjectRecordKeeping(HttpServletRequest request,
			@RequestParam("file") MultipartFile files, String recordingtime,
			int topicid,int userid,int praisepoints) {
		// 构建上传目录路径
		// request.getServletContext().getRealPath("/upload");
		String uploadPath = 你自己保存音频的URL;
		// 如果目录不存在就创建
		File uploadDir = new File(uploadPath);
		if (!uploadDir.exists()) {
			uploadDir.mkdir();
		}
		// 获取文件的 名称.扩展名
		String oldName = files.getOriginalFilename();
		String extensionName = "";
		// 获取原来的扩展名
		if ((oldName != null) && (oldName.length() > 0)) {
			int dot = oldName.lastIndexOf('.');
			if ((dot > -1) && (dot < (oldName.length() - 1))) {
				extensionName = oldName.substring(dot);
			}
		}
		// 构建文件名称
		String fileName = System.currentTimeMillis() + "_" + System.nanoTime()
				+ extensionName;
		// 获取
		String[] fileType = { ".CD", ".WAVE", ".AIFF", ".AU", ".MPEG", ".MP3",
				".MPEG-4", ".MIDI", ".WMA", ".RealAudio", ".VQF", ".OggVorbis",
				".AMR" };
		List<String> fileTyepLists = Arrays.asList(fileType);
		int fileTypeOnCount = 0;
		for (String fileTyepListss : fileTyepLists) {
			if (fileTyepListss.equalsIgnoreCase(extensionName)) {
				// -----如果是音频文件的话
				// 构建文件路径
				String filePath = uploadPath + File.separator + fileName;
				// 保存文件
				try {
					FileUtils.writeByteArrayToFile(new File(filePath),
							files.getBytes());
				} catch (Exception e) {
					e.printStackTrace();
				}
			} else {
				fileTypeOnCount++;
			}
		}
		if (fileTypeOnCount == fileTyepLists.size()) {
			// 不是音频文件
			return false;
		}
		return false;
	}
