我已经被 Vue.js 的补水问题困住了 2 天多，似乎找不到解决方案。
上下文：
我有一个页面，我想在其中呈现服务器端的一些文章，以便将它们包含在我的源代码中以获得更好的 SEO。这些文章从我的 Firestore 加载，然后发送到要显示的子组件。
这是我的页面组件：

如文档中所述，我已将 v-for 封装为仅限客户端。
为了调试，我设置了各种断点，以便能够从 hydr 函数读取 elm 对象，并尝试在此 html 对象中找到错误消息，但没有成功。我还尝试使用 asyncData 而不是 fetch 但无法访问它。我最近的测试是使用 promise 强制 Nuxt 等待获取完成，但也没有运气。
我认为问题是mounted是在我的fetch结束之前执行的，从而导致了这个错误。
编辑
如果我在 catch 中添加一个 console.log，我会得到这个：
ERROR Error [FirebaseError]: Function Query.where() called with invalid data. Unsupported field value: a custom Date object
所以如果我注释掉这一行：
.where("publishedDate", "<", new Date())
一切正常。
但现在我不知道为什么 new Date 在这里不起作用......以及用什么替换它......
答案 0 :(得分：0)
我通过将 Date 对象转换为 Firebase 时间戳解决了这个问题，如下所示：
const now = this.$fireModule.firestore.Timestamp.fromDate(new Date());
const querySnapshot = await this.$fire.firestore.collection("blogPosts")
.where("publishedDate", "<", now)
.orderBy("publishedDate", "desc")
.limit(3)
.get();
但是，我不明白为什么这会导致问题以及为什么 Date 可以在服务器端使用。如果有人能分享一些关于这方面的信息，那就太好了！
