我无法用getArguments(). 响应和 console.log 是（空的）。好像我错过了一些东西，但我无法确定在哪里：/

解决方案

您的代码中有一些常见错误，其中大部分已在此处提及，但请允许我总结一下。

扩展密钥/名称

首先，很多人混淆了扩展名和扩展键。在这种情况下，您的扩展的目录名称就是您的扩展密钥snippet_highlight_syntax。扩展密钥在 TYPO3 中被用作扩展的唯一标识符。Extbase 确实出现了一个新的约定，称为扩展名来满足PSR2 编码约定，并且主要用于 Extbase 上下文。扩展名是您的扩展密钥的大写驼峰式版本。

ExtbaseFluidBook: CodingGuidelines -它是旧的但仍然有效

UpperCamelCase 中的扩展名。例如，如果 extension-key 是 blog_example，那么这部分类名就是 BlogExample。

分机键：snippet_highlight_syntax
分机名称：SnippetHighlightSyntax

注意 TYPO3/Extbase 框架要求什么，键或名称——它会对你有很大帮助。

插件名称

您还声明了一个名为feshs. 根据这两种\TYPO3\CMS\Extbase\Utility\ExtensionUtility::(configure|register)Plugin()方法的 DocBlock 文档，与扩展名一样，它应该采用大写驼峰格式，例如Feshs. 它没有很好的记录，我认为它对您的应用程序没有任何负面影响，但现在您知道并且可以通过更正它来更改未来证明您的应用程序。

/**
 * ...
 *
 * @param string $extensionName The extension name (in UpperCamelCase) or the extension key (in lower_underscore)
 * @param string $pluginName must be a unique id for your plugin in UpperCamelCase (the string length of the extension key added to the length of the plugin name should be less than 32!)
 * @param array $controllerActions is an array of allowed combinations of controller and action stored in an array (controller name as key and a comma separated list of action names as value, the first controller and its first action is chosen as default)
 * @param array $nonCacheableControllerActions is an optional array of controller name and  action names which should not be cached (array as defined in $controllerActions)
 * @param string $pluginType either \TYPO3\CMS\Extbase\Utility\ExtensionUtility::PLUGIN_TYPE_PLUGIN (default) or \TYPO3\CMS\Extbase\Utility\ExtensionUtility::PLUGIN_TYPE_CONTENT_ELEMENT
 * @throws \InvalidArgumentException
 */
public static function configurePlugin($extensionName, $pluginName, array $controllerActions, array $nonCacheableControllerActions = [], $pluginType = self::PLUGIN_TYPE_PLUGIN)

插件签名

与您的扩展名一起，它将形成一个名为snippethighlightsyntax_feshs. 此签名是作为或取决于插件配置存储在tt_content数据库表中的值。list_typectype

插件签名在 TypoScript 和 GET/POST 参数中进一步使用，前缀为tx_. 在你的情况下tx_snippethighlightsyntax_feshs。

流体和 Extbase 形式

在您的表单片段中，您已经<f:form:textfield />使用property标签声明了一个元素。该property标记仅与元素上的objectandobjectName标记一起使用<f:form />，用于将值绑定到此对象的属性（自动填充、验证结果等）。

见\TYPO3\CMS\Fluid\ViewHelpers\Form\AbstractFormFieldViewHelper::initializeArguments。

Name of Object Property. If used in conjunction with <f:form object="...">, "name" and "value" properties will be ignored.

In your case you should properly just use name in stead of property.

Your updated form should look something like below:

<f:form id="snippetSearchForm"
        action="search"
        controller="Snippets"
        extensionName="SnippetHighlightSyntax"
        pluginName="Feshs"
        method="POST"
        pageType="5513">
    <f:form.textfield class="form-control" name="searchWords"/>
    <f:form.submit id="searchBtn" value="Search"/>
</f:form>

Controller arguments

You should declare your arguments as controller arguments.

/**
 * @param string $searchWords
 */
public function searchAction(string $searchWords = null)
{
    if (is_string($searchWords)) {
        // TODO: Do something here...
    }
}

Note how I have given the argument a default value. This should suppress the error Required argument "searchWords" is not set for... you are getting.

This was a long write up. Hopes it helps your or some others.

Happy coding
