编辑：
Helmut Hummel，TYPO3 CMS 团队的成员，measured 表示将 EID 与 Extbase 一起使用比使用 typeNum 方法要慢。但是由于typeNum方式配置繁琐，所以他开发了第三种方式。
扩展 typoscript_rendering 提供了一种无需额外配置即可直接调用 Extbase 操作的方法。它包含一个生成此类链接的 ViewHelper，可以在 Fluid 模板中像这样使用：
{namespace h=Helhum\TyposcriptRendering\ViewHelpers}
<script>
var getParticipationsUri = '<h:uri.ajaxAction controller="Participation" action="listByCompetition" arguments="{competition:competition}" />';
</script>
这会生成一个 URI，它调用我的“ParticipationController”的“listByCompetition”操作。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。所以如果你想在这样的请求中传递表单数据，你需要混合使用 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示例。您可以发布整个模型等）
EID方式：
是的，您可以为此使用 EID（扩展 ID）机制。没有官方声明应该使用哪种方式（pageType 或 eID）来进行 Extbase AJAX 调用，这似乎只是一个口味问题。
here 有一个不错的教程，我将源代码复制到这里：

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'
)
),

}
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
}
});
【讨论】：
我使用了一种没有 typeNum 的快速且可能很脏的方法。 我使用 jQuery ajax 调用的常用方式。 我的目标操作以以下结束。
$headers = DivUtilities::createHeader();
foreach ($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;
}
输出是被调用动作的模板。这可以是 html、json 或任何你需要的。
【讨论】：
我必须将 makeInstance 的第一个 0 更改为页面的 id 才能正常工作。
$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);
【讨论】：
对于 TYPO3 6.2 更改以下行：
\TYPO3\CMS\Core\Core\Bootstrap::getInstance()->loadConfigurationAndInitialize();
到
\TYPO3\CMS\Core\Core\Bootstrap::getInstance()
