我正在关注这个tutorial关于在 Nodejs 上使用 Express 和 AngularJS 构建单页应用程序。
我正在尝试从 Angular 模块调用 Web api，但我不断收到整个页面的 html 内容，而不是实际值
<!-- index.html -->
<!doctype html>
<!-- ASSIGN OUR ANGULAR MODULE -->
<html ng-app="scotchTodo">
<head>
<!-- META -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1"><!-- Optimize mobile viewport -->
<title>Node/Angular Todo App</title>
<!-- SCROLLS -->
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css"><!-- load bootstrap -->
<style>
html { overflow-y:scroll; }
body { padding-top:50px; }
#todo-list { margin-bottom:30px; }
</style>
<!-- SPELLS -->

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script><!-- load angular -->
<script src="core.js"></script>
</head>
<!-- SET THE CONTROLLER AND GET ALL TODOS -->
<body ng-controller="mainController">
<div class="container">
<!-- HEADER AND TODO COUNT -->
<div class="jumbotron text-center">
<h1>I'm a Todo-aholic <span class="label label-info">{{ todos.length }}</span></h1>
</div>
<!-- TODO LIST -->
<div id="todo-list" class="row">
<div class="col-sm-4 col-sm-offset-4">
<!-- LOOP OVER THE TODOS IN $scope.todos -->
<div class="checkbox" ng-repeat="todo in todos">
<label>
<input type="checkbox" ng-click="deleteTodo(todo._id)"> {{ todo.text }}
</label>
</div>
</div>
</div>
<!-- FORM TO CREATE TODOS -->
<div id="todo-form" class="row">
<div class="col-sm-8 col-sm-offset-2 text-center">
<form>
<div class="form-group">
<!-- BIND THIS VALUE TO formData.text IN ANGULAR -->
<input type="text" class="form-control input-lg text-center" placeholder="I want to buy a puppy that will love me forever" ng-model="formData.text">
</div>
<!-- createToDo() WILL CREATE NEW TODOS -->
<button type="submit" class="btn btn-primary btn-lg" ng-click="createTodo()">Add</button>
</form>
</div>
</div>
</div>
</body>
</html>

// public/core.js
var scotchTodo = angular.module('scotchTodo', []);
function mainController($scope, $http) {
$scope.formData = {};
// when landing on the page, get all todos and show them
$http.get('/api/something')
.success(function(data) {
$scope.todos = data;
console.log(data);
alert(data)
})
.error(function(data) {
console.log('Error: ' + data);
});
// when submitting the add form, send the text to the node API
$scope.createTodo = function() {
$http.post('/api/todos', $scope.formData)
.success(function(data) {
$scope.formData = {}; // clear the form so our user is ready to enter another
$scope.todos = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};
// delete a todo after checking it
$scope.deleteTodo = function(id) {
$http.delete('/api/todos/' + id)
.success(function(data) {
$scope.todos = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};

//server.js
// set up ========================
var express = require('express');
var app = express(); // create our app w/ express
// configuration =================
app.configure(function () {
app.use(express.static(__dirname + '/public')); // set the static files location /public/img will be /img for users
app.use(express.logger('dev')); // log every request to the console
app.use(express.bodyParser()); // pull information from html in POST
app.use(express.methodOverride()); // simulate DELETE and PUT
});
// listen (start app with node server.js) ======================================
app.listen(8080);
console.log("App listening on port 8080");
// 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)
});
// api routes
app.get('/api/something',function(req,res){
res.json({text: "1"});
});
// get all todos
app.get('/api/todos', function (req, res) {
console.log("api/todos")
var todos = [];
res.json(todos); // return all todos in JSON format
});
// 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);
});
});
});
但是我得到的不是我试图传递的值而是完整的 html:
最佳答案
这条路线...
// 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)
});
...正在响应所有 GET 请求，因为它位于 /api/something 路由之前。要么将其与 /api/something 路由交换...
app.get('/api/something',function(req,res){
res.json({text: "1"});
});
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)
});
或者不要使用通配符...
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)
});
