php - 从 cakephp 发送 xml 响应

Question

我想从我的 cakephp 控制器操作发送一个 xml 响应。我一直在尝试遵循官方指南：http ://book.cakephp.org/2.0/en/views/json-and-xml-views.html

但我不断收到此错误：

Missing View

Error: The view for ServicesController::index() was not found.

这就是我的服务控制器的样子：

<?php
class ServicesController extends AppController {

    var $uses = array();
    var $components = array('Auth','Session','RequestHandler');

    function beforeFilter() {
        $this->Auth->allow('index');
    }

    function index(){
        $output = array(
            "status" => "OK",
            "message" => "You are good"
        );

        $this->set('output', $output );
        $this->set('_serialize', array("output"));
   }
}
?>

我还将以下行添加到我的routes.php

Router::parseExtensions('json', 'xml');

我做错了什么？

您可以尝试将数组转换为 XML，回显输出并退出函数：

function index(){
    $output = array(
        "root" => array( // It needs one top element (http://book.cakephp.org/2.0/en/core-utility-libraries/xml.html#transforming-an-array-into-a-string-of-xml)
            "status" => "OK",
            "message" => "You are good"
        )
    );

    $xmlObject = Xml::fromArray($output);
    echo $xmlObject->asXML();
    exit;
}
