In the end the data is send in response but not in JSON format, so my movil app cannot process it no more. 最后,数据以响应方式发送,但不是以JSON格式发送,因此我的movil应用程序无法再处理它。
As I have said the service has been working fine till now. 正如我所说,该服务一直运作良好至今。 I don't know if this notices are related to the error, but they clearly seem to be. 我不知道这些通知是否与错误有关,但它们似乎很明显。
Can you point any direction of how can I debug this problem? 你能指出我如何调试这个问题的方向吗?
If this can be of any help here is my code: 如果这可以有任何帮助,这里是我的代码:
This is my index script where I configure Restler: 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();
And this is the public API class (I just show one method) 这是公共API类(我只显示一个方法)
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;
}
And this is the BaseDatos class method retrieving the info to be returned: 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;
}
The problem was related to my Doc Comments that I have recently added. 问题与我最近添加的文档评论有关。 The @class
tag I added in the Class Documentation was generating a conflict, maybe because the DocParser of Restler does not handle this specific tag. 我在类文档中添加的@class
标记产生了冲突,可能是因为Restler的DocParser不处理此特定标记。
The first 2 Notices I included in my question happened when DocParser tried to execute the formatClass()
method in response probably to the @class
tag and not to the Class
declaration in PHP. 我在问题中包含的前两个注意事项发生在DocParser尝试执行formatClass()
方法响应可能是@class
标签而不是PHP中的Class
声明时。
Maybe someone with deep understanding of this API can add some light. 也许对此API有深刻理解的人可以添加一些亮点。
Just removing this tag from docs and everything is working again. 只需从文档中删除此标记,一切都会再次运行。
