我正在尝试使用 LaTeX 为我的论文制作标题页，但什么都没有出现。我读过其他问题，但仍然无法正确完成。我所做的是：

但它没有在我的 LaTeX 文档中显示任何内容。我正在使用article文档类。
有人知道我应该做些什么不同的事情吗？

下面提到的几行导致了这个问题，
\usepackage{titlesec}
\titleformat{\chapter}{\LARGE\bfseries}{\thechapter.\ }{0em}{}
\AtBeginDocument{\AtBeginShipoutNext{\AtBeginShipoutDiscard}}
通过注释这些行，标题文本会出现在输出中
