node.js - Function.Module._resolveFilename (module.js:547:15) 在 Function.Module._load

Question

我收到以下错误

Function.Module._resolveFilename (module.js:547:15) at Function.Module._load (module.js:474:25) at Module.require (module.js:596:17) at require (internal/module.js :11:18) 在对象处。(C:\Users\u8ser\Desktop\Todo\server.js:25:1) 在 Module._compile (module.js:652:30) [nodemon] 应用程序崩溃 - 在启动前等待文件更改

您参考的 PFB 源代码。

我的 server.js 文件

var express = require("express");
var app = express();
var mongoose = require("mongoose");
var methodOverride = require("method-override");
var port = process.env.PORT || 8080;
var database = require('./config/database');
  var morgan = require("morgan");
var bodyParser = require("body-parser");

mongoose.connect('mongodb://localhost:27017', function(err){
    if (err){
        console.log(err);
    }else{
        console.log("Connected to DB");
    }
});

app.use(express.static(__dirname + '/public'));
app.use(morgan('dev'));
app.use(bodyParser.urlencoded({'extended':'true'}));
app.use(bodyParser.json());
app.use(bodyParser.json({ type : 'application/vnd.api+json'}));
app.use(methodOverride());

require('./models/routes')(app);

app.listen(port);
console.log("App listining to port" + port);

我的 routes.js 文件

var Todo = require('./models/todo');

module.exports = function(app){

    app.get('/api/todos', function(req, res){
    Todo.find(function(err, todos){
        if (err)
        res.send(err)

        res.send(todos)

      });
    });

 // create todo and send back all todos after creation

app.post('/api/todos', function(req, res){

    // create a todo, information comes from AJAX request from Angular

    Todo.create({
        text : req.body.text,
        done : false
    }, function(err, todo) {
        if (err)
           res.send(err);

       //get and return all the todos after you create another

       Todo.find(function(err, todos){
           if (err)
               res.send(err)
            res.json(todos);
       });
    });

});

//delete a todo
app.delete('/api/todos/:todo_id', function(req, res){
    Todo.remove({
       _id : req.params.todo_id
    }, function(err, todo){
        if (err)
        res.send(err);

        //get and return all the todos after you create another
        Todo.find(function(err, todos){
            if (err)
            res.send(err)
            res.json(todos);
        });
    });
});


// server.js 
// application -------------------------------------------------------------
app.get('*', function(req, res) {
    res.sendfile('./public/index.html'); // load the single view file (angular will handle the page changes on the front-end)
});

};

问题出在 server.js 文件中。尝试以下更新的解决方案

服务器.js：

var express = require("express");
var app = express();
var mongoose = require("mongoose");
var methodOverride = require("method-override");
var port = process.env.PORT || 8080;
var database = require('./config/database');
  var morgan = require("morgan");
var bodyParser = require("body-parser");
var routes = require('./app/models/routes');
mongoose.connect('mongodb://localhost:27017', function(err){
    if (err){
        console.log(err);
    }else{
        console.log("Connected to DB");
    }
});

app.use(express.static(__dirname + '/public'));
app.use(morgan('dev'));
app.use(bodyParser.urlencoded({'extended':'true'}));
app.use(bodyParser.json());
app.use(bodyParser.json({ type : 'application/vnd.api+json'}));
app.use(methodOverride());

app.use('/api', routes); // you should add base path like this and assign routes

app.listen(port);
console.log("App listining to port" + port);

在 routes.js 文件中删除 /api 因为我们在 server.js 中添加了 /api 作为基本路径

var Todo = require('./todo');

module.exports = function(app){

    app.get('/todos', function(req, res){
    Todo.find(function(err, todos){
        if (err)
        res.send(err)

        res.send(todos)

      });
    });

 // create todo and send back all todos after creation

app.post('/todos', function(req, res){

    // create a todo, information comes from AJAX request from Angular

    Todo.create({
        text : req.body.text,
        done : false
    }, function(err, todo) {
        if (err)
           res.send(err);

       //get and return all the todos after you create another

       Todo.find(function(err, todos){
           if (err)
               res.send(err)
            res.json(todos);
       });
    });

});

//delete a todo
app.delete('/todos/:todo_id', function(req, res){
    Todo.remove({
       _id : req.params.todo_id
    }, function(err, todo){
        if (err)
        res.send(err);

        //get and return all the todos after you create another
        Todo.find(function(err, todos){
            if (err)
            res.send(err)
            res.json(todos);
        });
    });
});

// server.js 
// application -------------------------------------------------------------
app.get('*', function(req, res) {
    res.sendfile('./public/index.html'); // load the single view file (angular will handle the page changes on the front-end)
});

};

架构应该以下面的方式创建，但是您所做的是错误的

var mongoose = require('mongoose');
const Schema = mongoose.Schema;
const BlogPost = new Schema({
  text : String,
  done : Boolean
});
module.exports = mongoose.model('Todo', BlogPost);
