Luracast Restler正在發送'text / html'而不是JSON

Question

我有一個使用LuraCast Restler API實現的REST Web服務。 它一直運作良好，直到現在。 突然之間，我沒有收到JSON數據以響應我對服務的請求。

對於每個服務請求，X-Debug始終返回以下通知。

最后，數據以響應方式發送，但不是以JSON格式發送，因此我的movil應用程序無法再處理它。

正如我所說，該服務一直運作良好至今。 我不知道這些通知是否與錯誤有關，但它們似乎很明顯。

你能指出我如何調試這個問題的方向嗎？

如果這可以有任何幫助，這里是我的代碼：

這是我配置Restler的索引腳本：

<?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();

這是公共API類（我只顯示一個方法）

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;
    }

這是檢索要返回的信息的BaseDatos類方法：

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;

}

Answer 1

問題與我最近添加的文檔評論有關。 我在類文檔中添加的@class標記產生了沖突，可能是因為Restler的DocParser不處理此特定標記。

我在問題中包含的前兩個注意事項發生在DocParser嘗試執行formatClass()方法響應可能是@class標簽而不是PHP中的Class聲明時。

也許對此API有深刻理解的人可以添加一些亮點。

只需從文檔中刪除此標記，一切都會再次運行。
