我是voiceXML的新手，我正在尝试使用evolution.voxeo.com来运行简单的XML代码。根据{{3}}，我们可以以多部分格式发布录制的音频。所以这是我的XML代码，运行良好，没有记录元素。但是当我添加记录元素时，我得到了错误。我收到错误的事实很奇怪，因为我收到了计算机中的实际音频文件。

这是我用来接收录制文件的node.js / express.js / multer代码
var express = require("express");
var bodyParser = require("body-parser");
var fs = require("fs");
var multer = require("multer");
var app = express();
app.set("view engine", "jade");
app.set("views", __dirname + "/views");
app.post("/", multer({
dest: "./uploads/",
rename: function (fieldname, filename) {
return hashCode(filename);
}
}));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true
}));
app.get("/", function (req, res) {
res.sendStatus(200);
});
app.post("/", function (req, res) {
res.sendStatus(200);
});
app.listen(80, function(){
console.log("listening ...");
});
function hashCode(str) {
var hash = 0;
if (str.length == 0) return hash;
for (i = 0; i < str.length; i++) {
char = str.charCodeAt(i);
hash = ((hash << 5) - hash) + char;
hash = hash & hash;
}
return hash >= 0 ? hash : -1 * hash;
}

对提交的http响应应该是要处理的下一个VoiceXML内容。我没有注意到您的内容中有任何暗示VoiceXML响应的内容，而错误是无法处理下一个文档。
