找不到文件404，而在HTML文件中使用腳本SRC標籤

-1

無法加載資源：服務器與404狀態（未找到）

迴應我試圖加載它的HTML文件中的

HTML文件：據app.html調用，加載爲默認的HTML文件。

Javascript文件：這是名稱core.js並放在與app.html相同的文件夾中。

angular.module('Todo', []) 

.controller('mainController', function($scope, $http) 
{ 
    $scope.formData = {}; 

    // get all and show them 
    $http.get('/musicians') 
     .success(function(data) { 
      $scope.todos = data; 
      console.log(data); 
     }) 
     .error(function(data) { 
      console.log('Error: ' + data); 
     }); 

     //get with an id 
     $scope.getOneTodo = function() { 
     $http.get('/musicians' + id) 
      .success(function(data) { 
       $scope.todos = data; 
         console.log(data); 
      }) 
      .error(function(data) { 
       console.log('Error: ' + data); 
      }); 
    }; 
     // send the text to the node API 
    $scope.createTodo = function() { 
     $http.post('/musicians', $scope.formData) 
      .success(function(data) { 
       $scope.formData = {}; // clear the form 
       $scope.todos = data; 
       console.log(data); 
      }) 
      .error(function(data) { 
       console.log('Error: ' + data); 
      }); 
    }; 

    // delete 
    $scope.deleteTodo = function(id) { 
     $http.delete('/musicians' + id) 
      .success(function(data) { 
       $scope.todos = data; 
         console.log(data); 
      }) 
      .error(function(data) { 
       console.log('Error: ' + data); 
      }); 
    }; 

    /* 
    $scope.updateTodo = function(id) { 
     $http.delete('/musicians' + id) 
      .success(function(data) { 
       $scope.todos = data; 
         console.log(data); 
      }) 
      .error(function(data) { 
       console.log('Error: ' + data); 
      }); 
    };*/ 

});

server.js看起來是這樣的：

var express = require('express'); 
var path = require('path'); 
//var favicon = require('serve-favicon'); 
var logger = require('morgan'); 
var cookieParser = require('cookie-parser'); 
var bodyParser = require('body-parser'); 
var mongoose = require('mongoose'), 
fs = require('fs'); 

var app = express(); 

var mongoUri = 'mongodb://localhost/DemoDB'; 


mongoose.connect(mongoUri); 
var db = mongoose.connection; 
db.on('error', function() { 
    throw new Error('unable to connect to database at ' + mongoUri); 
}); 



// view engine setup 
app.set('views', path.join(__dirname, 'views')); 
app.set('view engine', 'jade'); 

// uncomment after placing your favicon in /public 
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); 
app.use(logger('dev')); 
app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: false })); 
app.use(cookieParser()); 
app.use(express.static(path.join(__dirname, 'public'))); 

//app.use('/musicians',custom); 
require('./models/musician'); 
require('./routes/routes')(app); 

//page change at front end 


app.get('/', function(req, res) { 
     res.sendfile('app.html'); 
    }); 

// catch 404 and forward to error handler 
app.use(function(req, res, next) { 
    var err = new Error('Not Found'); 
    err.status = 404; 
    next(err); 
}); 







app.listen(3000, function() { 
    console.log("Listening on 3000"); 
}); 
module.exports = app;

你怎麼能指望我們來幫助你，當我們看到的只是一條錯誤信息？請發佈[mcve]。 – Cerbrus

@Cerbrus：用代碼更新。 –

錯誤發生在這裏：'Not Found at C：\ Users \ dev4 \ Desktop \ Sample \ server.js：48：13'因此請顯示'server.js' - 顯然... –

在server.js，後

app.get('/', function(req, res) { 
    res.sendfile('app.html'); 
});

添加

app.get('/core.js', function(req, res) { 
    res.sendfile('core.js'); 
});

沒有什麼區別。 –

你在哪裏添加它？ – Inkbug

我把它放在與app.html相同的文件夾中，app.html是應用程序的根文件夾。 –
