Question

有没有办法在不使用page typeNum？

的情况下在Extbase扩展中创建AJAX调用

Answer 1

修改

使用EID和Extbase的TYPO3 CMS团队成员measured的Helmut Hummel比使用typeNum方法慢。但由于typeNum方法配置起来很麻烦，因此他开发了第三种方法。

扩展程序typoscript_rendering提供了一种直接调用Extbase操作而无需其他配置的方法。它包含一个生成此类链接的ViewHelper，可以在Fluid模板中使用：

{namespace h=Helhum\TyposcriptRendering\ViewHelpers} <script> var getParticipationsUri = '<h:uri.ajaxAction controller="Participation" action="listByCompetition" arguments="{competition:competition}" />'; </script>

这将生成一个URI，该URI调用我的“ParticipationController”的动作“listByCompetition”。你可以正常传递参数。

唯一的缺点是出于安全原因，扩展使用cHash来验证请求参数。 cHash由GET提交，但您不能同时通过GET传递其他参数，因为它会使cHash无效。因此，如果您想在此类请求中传递表单数据，则需要混合使用GET（用于有效的AJAX调用）和POST（用于提交用户数据）：

<script> var createAddressUri = '<h:uri.ajaxAction controller="Address" action="create" />'; $body.on('submit', '#myForm', function(e) { e.preventDefault(); emailAddress = $('#myForm').find('#email'); if (typeof(emailAddress) === 'string') { $.ajax({ url: createAddressUri, type: 'POST', data: { 'tx_myext_pluginname[address][email]' : emailAddress}, success: function() { // things to do on success } }) } }); </script>

（当然这只是一个非常基本的例子。你可以发布整个模型等。）

EID方式：

是的，您可以使用EID（扩展ID）机制。官方声明没有哪种方式（pageType或eID）应该用于Extbase AJAX调用，这似乎只是一个品味问题。

有一个很好的教程可以找到here，我在这里复制源代码：

查看“使用此脚本”部分，了解如何注册eID。该脚本适用于TYPO3 6.1及更高版本。

Answer 2

对于TYPO3 6.2，请更改以下行：

\TYPO3\CMS\Core\Core\Bootstrap::getInstance()->loadConfigurationAndInitialize();

到

\TYPO3\CMS\Core\Core\Bootstrap::getInstance()

Answer 3

用于测试扩展。

在ext_localconf.php文件中包含EID

## Ajax configuration
$TYPO3_CONF_VARS['FE']['eID_include']['Test'] = \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extPath('test').'Classes/Ajax/EidDispatcher.php';

在类中创建目录 - Classes / Ajax / EidDispatcher.php

namespace TYPO3\Test\Ajax;

class EidDispatcher {
    /**
   * @var \array
   */
    protected $configuration;

    /**
   * @var \array
   */
    protected $bootstrap;

    /**
   * The main Method
   *
   * @return \string
   */
    public function run() {
        return $this->bootstrap->run( '', $this->configuration );
    }

    /**
   * Initialize Extbase
   *
   * @param \array $TYPO3_CONF_VARS
   */
    public function __construct($TYPO3_CONF_VARS) {

        $ajaxRequest = \TYPO3\CMS\Core\Utility\GeneralUtility::_GP('tx_Test_addhours');

        // create bootstrap
        $this->bootstrap = new \TYPO3\CMS\Extbase\Core\Bootstrap();

        // get User
        $feUserObj = \TYPO3\CMS\Frontend\Utility\EidUtility::initFeUser();

        // set PID
        $pid = (\TYPO3\CMS\Core\Utility\GeneralUtility::_GET( 'id' )) ? \TYPO3\CMS\Core\Utility\GeneralUtility::_GET('id') : 1;

        // Create and init Frontend
        $GLOBALS['TSFE'] = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance( 'TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController', $TYPO3_CONF_VARS, $pid, 0, TRUE );
        $GLOBALS['TSFE']->connectToDB();
        $GLOBALS['TSFE']->fe_user = $feUserObj;
        $GLOBALS['TSFE']->id = $pid;
        $GLOBALS['TSFE']->determineId();
        $GLOBALS['TSFE']->getCompressedTCarray(); //Comment this line when used for TYPO3 7.6.0 on wards
        $GLOBALS['TSFE']->initTemplate();
        $GLOBALS['TSFE']->getConfigArray();
        $GLOBALS['TSFE']->includeTCA(); //Comment this line when used for TYPO3 7.6.0 on wards

        // Get Plugins TypoScript
        $TypoScriptService = new \TYPO3\CMS\Extbase\Service\TypoScriptService();
        $pluginConfiguration = $TypoScriptService->convertTypoScriptArrayToPlainArray($GLOBALS['TSFE']->tmpl->setup['plugin.']['tx_Test.']);

        // Set configuration to call the plugin
        $this->configuration = array (
                'pluginName' => $ajaxRequest['pluginName'],
                'vendorName' => 'TYPO3',
                'extensionName' => 'Test',
                'controller' => $ajaxRequest['controller'],
                'action' => $ajaxRequest['action'],
                'mvc' => array (
                        'requestHandlers' => array (
                                'TYPO3\CMS\Extbase\Mvc\Web\FrontendRequestHandler' => 'TYPO3\CMS\Extbase\Mvc\Web\FrontendRequestHandler'
                        )
                ),
                'settings' => $pluginConfiguration['settings'],
                'persistence' => array (
                        'storagePid' => $pluginConfiguration['persistence']['storagePid']
                )
        );

    }
}
global $TYPO3_CONF_VARS;
// make instance of bootstrap and run
$eid = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance( 'TYPO3\Test\Ajax\EidDispatcher', $TYPO3_CONF_VARS );
echo $eid->run();

从脚本调用

$.ajax({
    async: 'true',
    url: 'index.php',      
    type: 'GET', 
    data: {
        eID: "Test",  
        tx_ExtName_PluginName: {
            pluginName:  'Plugin_Name',
            controller:  'Controller_Name',
            action:      'Action_Name',
        }
    },
    success:function(data){
        // code
    }
});

Answer 4

我必须将makeInstance的前0个更改为页面的ID才能生效。

$id = \TYPO3\CMS\Core\Utility\GeneralUtility::_GP('id');
$TSFE = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController', $TYPO3_CONF_VARS, $id, 0);

Answer 5

我使用了一种快速且可能很脏的方式而没有typeNum。我用jQuery ajax调用常用的方法。我的目标行动结束了以下内容。

$headers = DivUtilities::createHeader();
foreach ($headers as $header => $data) {
    $this->response->setHeader($header, $data);
}
$this->response->sendHeaders();
echo $this->view->render();
exit;

createHeader方法

/**
  *
  * @param string $type
  * @return array
  */
public static function createHeader($type = 'html')
{
  switch ($type) {
    case 'txt':
            $cType   = 'text/plain';
            break;
    case 'html':
            $cType   = 'text/html';
            break;
    case 'json':
            $cType   = 'application/json';
            break;
    case 'pdf':
            $cType   = 'application/pdf';
            break;
  }
  $headers = array(
          'Pragma' => 'public',
          'Expires' => 0,
          'Cache-Control' => 'must-revalidate, post-check=0, pre-check=0',
          'Cache-Control' => 'public',
          'Content-Type' => $cType
  );
  return $headers;
}

输出是被调用操作的模板。这可以是html，json或者你需要的任何东西。
