我想将以HTML格式输入的数据存储到 mongoDB ，但它显示错误消息-“ TypeError：无法读取未定义的属性'fullname'”

看起来一切都正确，但我不知道我哪里错了。请帮助我清除此错误。

server.js

var express = require("express");
var app = express();
var path = require("path");
"use strict";
const mongoose = require("mongoose");
mongoose.connect("mongodb://localhost:27017/lp", {useNewUrlParser: true});
mongoose.set("useCreateIndex", true);
mongoose.Promise = global.Promise;
var Schema = mongoose.Schema;
var engines = require("consolidate");
app.use(express.static(path.join(__dirname, "public")));
app.set("views", __dirname + "/views");
app.engine("html", engines.mustache);
app.set("view engine", "html");
var enrollDataSchema = new Schema({
    fullname: {type: String},
    emailId: {
        type: String,

    var data = new EnrollData(userinfo);
    data.save(function (err, result) {
        if (err) {
            console.log(err);
        } else {
            res.render("thankyou.html");
        }
    });
});
app.listen(8000);
console.log("Running at Port 8000");

index.html

能否请您尝试使用body-parser模块。

var bodyParser = require('body-parser')

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))

// parse application/json
app.use(bodyParser.json())
