微信语音上传 下载

假如现在有一个按钮 

  
按住 说话

下面就是调用微信jssdk的方法

        var recorder;
        var btnRecord = $('#record');
        var startTime = 0;
        var recordTimer = 300;
var url=window.location.href; // 发语音 $.ajax({ url: 'url请求需要微信的一些东西 下面success就是返回的东西', type: 'get', data: { url: url }, success: function (data) { var json = $.parseJSON(data); //alert(json); //假设已引入微信jssdk。【支持使用 AMD/CMD 标准模块加载方法加载】 wx.config({ debug: false, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。 appId: json.appid, // 必填,公众号的唯一标识 timestamp: json.timestamp, // 必填,生成签名的时间戳 nonceStr: json.nonceStr, // 必填,生成签名的随机串 signature: json.signature, // 必填,签名,见附录1 jsApiList: [ "startRecord", "stopRecord", "onVoiceRecordEnd", "playVoice", "pauseVoice", "stopVoice", "onVoicePlayEnd", "uploadVoice", "downloadVoice", ] // 必填,需要使用的JS接口列表,所有JS接口列表见附录2 }); wx.ready(function () { btnRecord.on('touchstart', function (event) { event.preventDefault(); startTime = new Date().getTime(); // 延时后录音,避免误操作 recordTimer = setTimeout(function () { wx.startRecord({ success: function () { localStorage.rainAllowRecord = 'true'; //style="display:block" $(".voice_icon").css("display", "block"); }, cancel: function () { layer.open({ content: '用户拒绝了录音授权', btn: '确定', shadeClose: false, }); } }); }, 300); }).on('touchend', function (event) { event.preventDefault(); // 间隔太短 if (new Date().getTime() - startTime < 300) { startTime = 0; // 不录音 clearTimeout(recordTimer); } else { // 松手结束录音 wx.stopRecord({ success: function (res) { $(".voice_icon").css("display", "none"); voice.localId = res.localId; // 上传到服务器 uploadVoice(); }, fail: function (res) { //alert(JSON.stringify(res)); layer.open({ content: JSON.stringify(res), btn: '确定', shadeClose: false, }); } }); } }); }); }, error: function () { } })

 上传语音的方法 

 function uploadVoice() {
        //调用微信的上传录音接口把本地录音先上传到微信的服务器
        //不过,微信只保留3天,而我们需要长期保存,我们需要把资源从微信服务器下载到自己的服务器
        wx.uploadVoice({
            localId: voice.localId, // 需要上传的音频的本地ID,由stopRecord接口获得
            isShowProgressTips: 1, // 默认为1,显示进度提示
            success: function (res) {
                // alert(JSON.stringify(res));
                //把录音在微信服务器上的id(res.serverId)发送到自己的服务器供下载。
                voice.serverId = res.serverId;
                $.ajax({
                    url: '/QyhSpeech/DownLoadVoice',
                    type: 'post',
                    data: { serverId: res.serverId, Id: Id },
                    dataType: "json",
                    success: function (data) {
                        if (data.Result == true && data.ResultCode == 1) {
                            layer.open({
                                content: "录音上传完成!",//data.Message
                                btn: '确定',
                                shadeClose: false,
                                yes: function (index) {
                                    window.location.href = window.location.href;
                                }
                            });
                        }
                        else {
                            layer.open({
                                content: data.Message,
                                btn: '确定',
                                shadeClose: false,
                            });
                        }
                    },
                    error: function (xhr, errorType, error) {
                        layer.open({
                            content: error,
                            btn: '确定',
                            shadeClose: false,
                        });
                    }
                });

            }
        });
    }

  后台调用的方法     需要一个ffmpeg.exe自行下载

 //下载语音并且转换的方法
        private string GetVoicePath(string voiceId, string access_token)
        {
            string voice = "";
            try
            {
                Log.Debug("access_token:", access_token);
                //调用downloadmedia方法获得downfile对象
                DownloadFile downFile = WeiXin.DownloadMedia(voiceId, access_token);
                if (downFile.Stream != null)
                {
                    string fileName = Guid.NewGuid().ToString();
                    //生成amr文件
                    string amrPath = Server.MapPath("~/upload/audior/");
                    if (!Directory.Exists(amrPath))
                    {
                        Directory.CreateDirectory(amrPath);
                    }
                    string amrFilename = amrPath + fileName + ".amr";
                    //var ss = GetAMRFileDuration(amrFilename);
                    //Log.Debug("ss", ss.ToString());
                    using (FileStream fs = new FileStream(amrFilename, FileMode.Create))
                    {
                        byte[] datas = new byte[downFile.Stream.Length];
                        downFile.Stream.Read(datas, 0, datas.Length);
                        fs.Write(datas, 0, datas.Length);
                    }
                    //转换为mp3文件
                    string mp3Path = Server.MapPath("~/upload/audio/");
                    if (!Directory.Exists(mp3Path))
                    {
                        Directory.CreateDirectory(mp3Path);
                    }
                    string mp3Filename = mp3Path + fileName + ".mp3";
                    AudioHelper.ConvertToMp3(Server.MapPath("~/ffmpeg/"), amrFilename, mp3Filename);
                    voice = fileName;
              
                    Log.Debug("voice:", voice);
                }
            }
            catch { }
            return voice;
        }

  调用GetVoicePath

 //下载微信语音文件
        public JsonResult DownLoadVoice()
        {
            var file = "";
            try
            {
                var serverId = Request["serverId"];//文件的serverId
                file = GetVoicePath(serverId, CacheHelper.GetAccessToken());
                return Json(new ResultJson { Message = file, Result = true, ResultCode = 1 });
            }
            catch (Exception ex)
            {
                return Json(new ResultJson { Message = ex.Message, Result = false, ResultCode = 0 });
            }

        }

  文中需要  DownloadFile downFile = WeiXin.DownloadMedia(voiceId, access_token); 需要一个类库 到时候直接放到项目里面即可(我也是找到)
