假如現在有一個按鈕
<div class="inp_btn voice_btn active" id="record">
按住 說話
</div>
下麵就是調用微信jssdk的方法
var recorder;
var btnRecord = $('#record');
var startTime = 0;
var recordTimer = 300;
// 發語音
$.ajax({
url: 'url請求需要微信的一些東西 下麵success就是返回的東西',
type: 'get',
data: { url: url },
success: function (data) {
var json = $.parseJSON(data);
//alert(json);
//假設已引入微信jssdk。【支持使用 AMD/CMD 標準模塊載入方法載入】
wx.config({
debug: false, // 開啟調試模式,調用的所有api的返回值會在客戶端alert出來，若要查看傳入的參數，可以在pc端打開，參數信息會通過log打出，僅在pc端時才會列印。
appId: json.appid, // 必填，公眾號的唯一標識
timestamp: json.timestamp, // 必填，生成簽名的時間戳
nonceStr: json.nonceStr, // 必填，生成簽名的隨機串

});
wx.ready(function () {
btnRecord.on('touchstart', function (event) {
event.preventDefault();
startTime = new Date().getTime();
// 延時後錄音，避免誤操作
recordTimer = setTimeout(function () {
wx.startRecord({
success: function () {
localStorage.rainAllowRecord = 'true';
//style="display:block"
$(".voice_icon").css("display", "block");
},
cancel: function () {
layer.open({
content: '用戶拒絕了錄音授權',
btn: '確定',
shadeClose: false,
});
}
});
}, 300);
}).on('touchend', function (event) {
event.preventDefault();
// 間隔太短
if (new Date().getTime() - startTime < 300) {
startTime = 0;
// 不錄音
clearTimeout(recordTimer);
} else { // 鬆手結束錄音
wx.stopRecord({
success: function (res) {
$(".voice_icon").css("display", "none");
voice.localId = res.localId;
// 上傳到伺服器
uploadVoice();
},
fail: function (res) {
//alert(JSON.stringify(res));
layer.open({
content: JSON.stringify(res),
btn: '確定',
shadeClose: false,
});
}
});
}
});
});
},
error: function () { }
})
上傳語音的方法
function uploadVoice() {
//調用微信的上傳錄音介面把本地錄音先上傳到微信的伺服器
//不過，微信只保留3天，而我們需要長期保存，我們需要把資源從微信伺服器下載到自己的伺服器
wx.uploadVoice({
localId: voice.localId, // 需要上傳的音頻的本地ID，由stopRecord介面獲得
isShowProgressTips: 1, // 預設為1，顯示進度提示
success: function (res) {
// alert(JSON.stringify(res));
//把錄音在微信伺服器上的id（res.serverId）發送到自己的伺服器供下載。
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: "錄音上傳完成！",//data.Message
btn: '確定',
shadeClose: false,
yes: function (index) {
window.location.href = window.location.href;
}
});
}
else {
layer.open({
content: data.Message,
btn: '確定',
shadeClose: false,
});
}
},
error: function (xhr, errorType, error) {
layer.open({
content: error,
btn: '確定',
shadeClose: false,
});
}
});
}
});
}
後臺調用的方法 需要一個ffmpeg.exe自行下載
//下載語音並且轉換的方法
private string GetVoicePath(string voiceId, string access_token)
{
string voice = "";
try
{
Log.Debug("access_token:", access_token);
//調用downloadmedia方法獲得downfile對象
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);
}
//轉換為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;
}
調用GetVoicePath
//下載微信語音文件
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); 需要一個類庫 到時候直接放到項目裡面即可（我也是找到）
