Question

当我运行localhost：3000服务器时，我在控制台中收到这些错误：

http://localhost:3000/bower_components/angular/angular.js无法加载资源：服务器响应状态为404（未找到）

http://localhost:3000/controller.js无法加载资源：服务器响应状态为404（未找到）

如果我将angular.js脚本放在index.html中而不是将它单独放在controller.js中，我就知道为什么我在使用脚本标签时出错了

目录图是这样的

-files
  -bower_components
    -angular
  -index.html
  -controller.js
  -server.js

这是index.html文件

<!DOCTYPE html>
<html ng-app="App">
<head>
<style>
#list   
{ margin-left:320px;
  font-size: 40px;
  font-family:verdana;
}
button     
{ color:yellow;background-color:red;text-align:center;cursor:pointer;
  -webkit-transition-duration: 0.4s;
  transition-duration: 0.4s;
  font-size:40px;
  padding: 14px 32px;
}
button:hover
{ background-color:peachpuff;
  color:tomato;
}
</style>
</head>

<body style="background-color:cyan;">

<div ng-controller="Ctrl">

<h1 style="text-align:center;font-family:verdana;">To-Do LiSt</h1>

<div style="margin-left:300px">
<input type="text" ng-model="task.name" style="background-color:black;color:white;font-size:40px;width:40%">
<button ng-click="addtask()">Add</button>&nbsp;
<button ng-click="updatetask()">Update</button>&nbsp;<button ng-click="clearfield()">Clear</button>
</div>

<ul>
<li id="list" ng-repeat="task in todolist">
{{task.name}}
<button ng-click="deletetask(task._id)">Delete</button>&nbsp;&nbsp;<button ng-click="edittask(task._id)">Edit</button>
</li>
</ul>

</div>


</body>

<script type="text/javascript" src="bower_components/angular/angular.js"></script>
<script type="text/javascript" src="controller.js"></script>

</html>

这是server.js文件

var express = require('express');
var app = express();
var mongoose = require('mongoose');
var bodyParser = require('body-parser');
app.use(bodyParser.json());

mongoose.connect("mongodb://localhost/test");

var TodoSchema = new mongoose.Schema ({
 name : {type: String, required: true}
 });

var TodoModel = mongoose.model('todolist',TodoSchema);

app.get('/',function(req,res){

    res.sendFile("/index.html",{root:__dirname}); 
});

app.get('/todolist', function (req, res){
    TodoModel.find(function(err,tasks){
      res.json(tasks);
     });
});

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

  TodoModel.create({name:req.body.name},function(err,task){
    res.send('created');
  });

});

app.delete('/todolist/:id', function (req, res) {

 TodoModel.remove({_id:req.params.id}, function (err) {
     res.send('');
 });
});

app.get('/todolist/:id', function (req, res) {

  TodoModel.findById(req.params.id, function (err, task){
    res.json(task);
  });
});

app.put('/todolist/:id', function (req, res) {

  TodoModel.findByIdAndUpdate(req.params.id,
     {name: req.body.name},
      function (err, task) {

      res.json(task);
    }
  );
});

app.listen(3000);
console.log("Server running on port 3000");

在server.js文件中添加以下行并检查一次。

app.use(express.static(__dirname));

在节点js中，您必须设置注册表以访问相对路径。

无法加载java脚本文件和bower_components / angular / angular.js
