Php 卢拉卡斯特·雷斯勒正在发送'；text/html'；而不是JSON

我有一个用LuraCast Restler API实现的REST web服务。到目前为止，它一直运转良好。突然间，我无法再获得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

最后，数据以响应方式发送，但不是JSON格式，因此我的movil应用程序无法再处理它

正如我所说，到目前为止，这项服务一直运作良好。我不知道这些通知是否与错误有关，但它们显然与错误有关

你能告诉我如何调试这个问题吗

如果这有什么帮助的话，下面是我的代码：

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BaseDatos类方法，用于检索要返回的信息：

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文档注释有关。类文档中添加的

@class

标记生成了冲突，可能是因为Restler的DocParser没有处理这个特定标记

我在问题中提到的前两个注意事项发生在DocParser试图执行

formatClass（）

方法时，这可能是对

@class

标记的响应，而不是对PHP中的

class

声明的响应

也许对这个API有深入了解的人可以添加一些说明

---

只要从文档中删除此标签，一切都会恢复正常。

感谢@david casillas报告此问题。您是对的，

@class

应为特定格式，这导致了问题。我们将在下一版本中修复它

@class

当前用于在初始化后设置另一个类的属性。阅读更多细节。

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;

}
