问题描述
在不使用 $resource
的情况下,在 AngularJS 中连接到服务器数据源的推荐方法是什么.
What is the recommended way to connect to server data sources in AngularJS without using $resource
.
$resource
有很多限制,例如:
- 未使用正确的期货
- 不够灵活
推荐答案
有些情况下 $resource 在与后端交谈时可能不合适.这展示了如何在不使用资源的情况下设置类似 $resource 的行为.
There are cases when $resource may not be appropriate when talking to backend. This shows how to set up $resource like behavior without using resource.
angular.module('myApp').factory('Book', function($http) {
// Book is a class which we can use for retrieving and
// updating data on the server
var Book = function(data) {
angular.extend(this, data);
}
// a static method to retrieve Book by ID
Book.get = function(id) {
return $http.get('/Book/' + id).then(function(response) {
return new Book(response.data);
});
};
// an instance method to create a new Book
Book.prototype.create = function() {
var book = this;
return $http.post('/Book/', book).then(function(response) {
book.id = response.data.id;
return book;
});
}
return Book;
});
然后在您的控制器中,您可以:
Then inside your controller you can:
var AppController = function(Book) {
// to create a Book
var book = new Book();
book.name = 'AngularJS in nutshell';
book.create();
// to retrieve a book
var bookPromise = Book.get(123);
bookPromise.then(function(b) {
book = b;
});
};
