我有一个使用 LuraCast Restler API 实现的 REST Web 服务。到目前为止，它一直运行良好。突然间，我不再响应我对服务的请求而获得 JSON 数据。

X-Debug 总是在对服务的每个请求中返回以下通知。

最后，数据是作为响应发送的，但不是以 JSON 格式发送的，所以我的 movil 应用程序无法再处理它。

正如我所说，到目前为止，该服务一直运行良好。我不知道这个通知是否与错误有关，但它们显然似乎是。

你能指出我如何调试这个问题的任何方向吗？

如果这有任何帮助，这里是我的代码：

这是我配置 Restler 的索引脚本：

<?php

require_once '../../BaseDatos.php';
require_once 'restler/restler.php';

#set autoloader
#do not use spl_autoload_register with out parameter
#it will disable the autoloading of formats
spl_autoload_register('spl_autoload');


$r = new Restler();
$r->setSupportedFormats('JsonFormat');
$r->addAPIClass('Rest');
$r->addAuthenticationClass('Seguridad');
$r->handle();

这是公共 API 类（我只展示一种方法）

class Rest
{

    /**
     * @brief Una instancia de la clase BaseDatos
     *
     * @var BaseDatos $db
     */
    private $db;

    /**
     * \brief Constructor de la clase.
     *
     * Inicializa una instancia de la clase BaseDatos.
     *
     */
    function __construct() {
        $this->db = BaseDatos::getInstance();
    }
    public function getFuentes($nombreUsuario, $password) {

        $fuentes = $this->db->getFuentes();
        $fuentes = array('fuentes' => $fuentes);
        return $fuentes;
    }

这是检索要返回的信息的 BaseDatos 类方法：

public function getFuentes() {
    //SELECT * FROM fuentes
    $queryString = 'SELECT * FROM ' . TABLA_FUENTES . ' ORDER BY nombreFuente';
    $queryResult = $this->query($queryString);
    if ($this->errno != 0) {
        //ERRRO. mysql
        $this->setErrorNoAndMessage(ErrorCode::ERROR_MYSQL, $this->error);
        return FALSE;
    }
    $resultado = array();
    while ($row = $queryResult->fetch_assoc() ) {
        $resultado[] = $row;
    }

    $this->resetErrorNoAndMessage();
    return $resultado;

}

该问题与我最近添加的文档评论有关。我在类文档中添加的@class标签产生了冲突，可能是因为 Restler 的 DocParser 没有处理这个特定的标签。

我在问题中包含的前 2 个通知发生在 DocParser 尝试执行该formatClass()方法以响应@class标签而不是ClassPHP 中的声明时。

也许对这个 API 有深入了解的人可以补充一些亮点。

只需从文档中删除此标签，一切都会恢复正常。
