Luracast Restler正在发送'text/html‘而不是JSON
Luracast Restler正在发送'text/html‘而不是JSON
提问于 2012-05-02 17:19:15
我有一个用LuraCast Restler API实现的REST web服务。到目前为止，它一直运行得很好。突然之间，我不再获得JSON数据来响应我对服务的请求。
X-Debug总是在每次请求服务时返回以下通知。

正如我已经说过的那样，到目前为止，这项服务一直运行良好。我不知道这些通知是否与这个错误有关，但它们显然是相关的。
你能指出我该如何调试这个问题吗？
如果这能有任何帮助，这里是我的代码：
这是我的索引脚本，我在其中配置Restler：
<?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(我只展示了一个方法)
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;
}下面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;

这个问题与我最近添加的Doc注释有关。我在类文档中添加的Restler标记产生了冲突，可能是因为@class的DocParser不处理这个特定的标记。
我在问题中提到的前两个注意事项发生在DocParser尝试执行formatClass()方法时，可能是响应@class标记，而不是响应PHP语言中的Class声明。
也许对此API有深入了解的人可以补充一些内容。
只需从文档中删除此标记，一切都可以正常工作。
