晚上好。我正在网站上。我正在尝试从页面下面的文件中发布json数据。我为这节经文写了一个网址。在页面上，我得到书，章节和经文。有人能向我解释一下如何从正确页面上的bibelVerse获取文本。

Answer 1

如果您只想返回经文，则需要编写一些内容以在数组中找到正确的经文。所以我会做这样的事情...

let foundVerse = bibleVerse.find(function(verseEl) {
    return verseEl.book === book && verseEl.chapter === chapter && verseEl.verse === verse;
});

您可能还需要验证从req.params获得的这些值，以确保您拥有有效的数据。

这时，您将拥有匹配的项目或null的{{1}}对象。因此，您可以编写一些逻辑以发送回正确的响应（我假设是文本？）。
