Question

我一直收到错误消息＆＃34; TypeError：无法在＆＃39;中使用＆＃39;运营商搜索＆＃39; _id＆＃39; in＆＃34; +＆＃34; mongoose＆＃34;，＆＃34; body-parser＆＃34;，＆＃34; ./ config＆＃34; ......显然任何依赖。我试过了：

确保我的模型/模式正确，如下所示：TypeError: Cannot use 'in' operator to search for '_id' in male
完全评论任何对req.body的提及，以避免导致错误的任何可能性，如下所述：TypeError: Cannot use 'in' operator to search for '_id' in [{}]和此处：Mongoose TypeError: Cannot use 'in' operator to search for '_id' in [object Object]
阅读本文，但不知道这里发生了什么：Mongoose TypeError: Cannot use 'in' operator to search for '_id' in
我试着注释掉我认为可能导致问题的config.js文件的部分内容。（见下文）
我甚至试图完全评论出有问题的依赖关系（例如，注释掉var config = require('./config')），这显然不是一个可行的长期解决方案，但也没有摆脱我的错误。相反，这只是将错误移到了不同的依赖项（例如，现在它正在考虑使用mongoose本身）。

所以现在我很难过。

这是我的用户模型：

"use strict";

var mongoose = require('mongoose');

var userSchema = new mongoose.Schema({
    username: {
        type: String,
        required: false},
    password: {
        type: String,
        required: false}
});

var user = mongoose.model('user', userSchema);

module.exports = user;

这是我的server.js：

"use strict";

var require = require('./models/user');
//var bodyParser = require('body-parser');
//var config = require('./config');
var mongoose = require('mongoose');
var express = require('express');
var app = express();
//app.use(bodyParser.json());
app.use(express.static('public'));

var runServer = function (callback) {
    mongoose.connect(config.DATABASE_URL, function (err) {
        if (err && callback) {
            return callback(err);
        }

        app.listen(config.PORT, function () {
            console.log('Listening on localhost:' + config.PORT);
            if (callback) {
                callback();
            }
        });
    });
};

if (require.main === module) {
    runServer(function (err) {
        if (err) {
            console.error(err);
        }
    });
};


app.post('/login', function(req, res) {
    console.log(req);
    //console.log(req.body.password);
    user.create({
        username: 'Test',
        password: '1234'
        //username: req.body.username,
        //password: req.body.password
    }, function (err, user) {
        if(err) {
            return res.status(500).json({
                message: 'Internal Server Error'
            });
        }
        res.status(201).json(user);
        console.log(user);
    });
});

exports.app = app;
exports.runServer = runServer;

app.listen(process.env.PORT || 8080);

这是我的config.js文件：

exports.DATABASE_URL = process.env.DATABASE_URL || global.DATABASE_URL 
|| 'mongodb://demo:demo@ds121483.mlab.com:21483/job-tracker-data';
//exports.TEST_DATABASE_URL = process.env.TEST_DATABASE_URL ||
    //'mongodb://demo:demo@ds121483.mlab.com:21483/job-tracker-data';
exports.PORT = process.env.PORT || 8080;

以下是错误消息的示例：
