我是 voiceXML 的新手，我正在尝试使用 evolution.voxeo.com运行简单的 XML 代码。根据their website ，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，它在没有记录元素的情况下运行良好。但是当我添加记录元素时，出现错误。我收到错误的事实很奇怪，因为我正在计算机中接收实际的音频文件。

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;
}

最佳答案

提交的 http 响应应该是下一个要处理的 VoiceXML 内容。我没有注意到您的内容中有任何提示 VoiceXML 响应的内容，错误是关于无法处理下一个文档。

关于javascript - evolution.voxeo.com 中的 voiceXML，出现奇怪的错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33967229/
