TYPO3 9.5 中间件渲染页面模板

编程问答 2022-05-29

问题描述

我正在尝试从 Middleware 中呈现页面，因为它会在没有 Middleware 的情况下呈现，但我想更改内容（模板的主要部分）除外。

目前我正在使用 \TYPO3Fluid\Fluid\View\TemplateView 这样做。但是一旦 Layout 被呈现，其中包含网站标题、导航等。我在第 109 行的 Call to undefined method TYPO3Fluid\Fluid\Core\Rendering\RenderingContext::getControllerContext() 中收到错误 sysext/fluid/Classes/ViewHelpers/Link/PageViewHelper.PHP：$uriBuilder = $this->renderingContext->getControllerContext()->getUriBuilder();。

我需要在我的 Context 中添加另一个 View 还是有其他方法可以更改 Middleware 中的内容？
