[英]CakePHP - creating an API for my cakephp app
I have created a fully functional CakePHP web application. 我创建了一个功能齐全的CakePHP Web应用程序。 Now, i wanna get it to the next level and make my app more "opened". 现在,我想把它提升到一个新的水平,让我的应用程序更“开放”。 Thus i want to create an RESTful API. 因此,我想创建一个RESTful API。 In the CakePHP docs,i found this link ( http://book.cakephp.org/2.0/en/development/rest.html ) which describes the way to make your app RESTful. 在CakePHP文档中,我找到了这个链接( http://book.cakephp.org/2.0/en/development/rest.html ),它描述了使您的应用程序RESTful的方法。 I added in the routes.php the the two lines needed,as noted at the top of the link,and now i want to test it. 我在routes.php中添加了所需的两行,如链接顶部所示,现在我想测试它。 I have an UsersController.php controller,where there is a function add(),which adds new users to databases. 我有一个UsersController.php控制器,其中有一个函数add(),它将新用户添加到数据库。 But when i try to browse under mydomain.com/users.json (even with HTTP POST),this returns me the webpage,and not a json formatted page,as i was expecting . 但是,当我尝试在mydomain.com/users.json下浏览时(即使使用HTTP POST),这会返回我的网页,而不是像我期望的那样返回json格式的页面。
Now i think that i have done something wrong or i have not understood something correctly. 现在我认为我做错了什么或者我没有正确理解。 What's actually happening,can you help me a bit around here? 实际发生了什么,你能帮我一点吗?
Thank you in advace! 谢谢你的推荐!
You need to parse JSON extensions. 您需要解析JSON扩展。 So in your routes.php file add: 所以在你的routes.php文件中添加:
Router::parseExtensions('json');
So a URL like http://example.com/news/index you can now access like http://example.com/news/index.json . 因此,像http://example.com/news/index这样的网址现在可以访问http://example.com/news/index.json 。
To actually return JSON though, you need to amend your controller methods. 要实际返回JSON,您需要修改控制器方法。 You need to set a _serialize
key in your action, so your news controller could look like this: 您需要在操作中设置_serialize
键,因此您的新闻控制器可能如下所示:
<?php
class NewsController extends AppController {
public function index() {
$news = $this->paginate('News');
$this->set('news', $news);
$this->set('_serialize', array('news'));
}
}
That's the basics. 这是基础知识。 For POST requests, you'll want to use the RequestHandler
component. 对于POST请求,您将需要使用RequestHandler
组件。 Add it to your controller: 将其添加到您的控制器:
<?php
class NewsController extends AppController {
public $components = array(
'RequestHandler',
...
);
And then you can check if an incoming request used the .json file extension: 然后你可以检查传入的请求是否使用.json文件扩展名:
public function add() {
if ($this->RequestHandler->extension == 'json') {
// JSON request
} else {
// do things as normal
}
}
