WechatVoiceController.cs

using Loogn.WeiXinSDK; using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Web; using System.Web.Mvc; using WuDemo.Common; namespace WuDemo.Controllers { public class WechatVoiceController : Controller { // GET: WechatVoice public ActionResult Index() { return View(); } //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 }); } } //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; } } }

AudioHelper.cs

using System; using System.Collections.Generic; using System.Linq; using System.Threading; using System.Web; namespace WuDemo.Common { /// <summary> /// 声音帮助类 /// </summary> public sealed class AudioHelper { private const string FfmpegUsername = "ffmpeg"; private const string FfmpegPassword = "it4pl803"; /// <summary> /// 音频转换 /// </summary> /// <param name="ffmpegPath">ffmpeg文件目录</param> /// <param name="soruceFilename">源文件</param> /// <param name="targetFileName">目标文件</param> /// <returns></returns> public static string ConvertToMp3(string ffmpegPath, string soruceFilename, string targetFileName) { //string cmd = ffmpegPath + @"\ffmpeg.exe -i " + soruceFilename + " " + targetFileName; string cmd = ffmpegPath + @"\ffmpeg.exe -i " + soruceFilename + " -ar 44100 -ab 128k " + targetFileName; return ConvertWithCmd(cmd); } private static string ConvertWithCmd(string cmd) { try { System.Diagnostics.Process process = new System.Diagnostics.Process(); process.StartInfo.FileName = "cmd.exe"; process.StartInfo.UseShellExecute = false; process.StartInfo.CreateNoWindow = true; process.StartInfo.RedirectStandardInput = true; process.StartInfo.RedirectStandardOutput = true; process.StartInfo.RedirectStandardError = true; process.Start(); process.StandardInput.WriteLine(cmd); process.StandardInput.AutoFlush = true; Thread.Sleep(1000); process.StandardInput.WriteLine("exit"); process.WaitForExit(); string outStr = process.StandardOutput.ReadToEnd(); process.Close(); return outStr; } catch (Exception ex) { return "error" + ex.Message; } } } }

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） http://files.cnblogs.com/files/hbh123/Loogn.WeiXinSDK.rar
