您是否使用 WPGraphQL 作为您的端点？你也很可能需要一个不记名令牌，除非你的端点可以被公开自省。我会从我当前的无头 wordpress 版本中发布一些文件
首先，考虑使用类似 apollo 客户端的东西来提供全局一致的缓存。 SWR 和 GraphQL Query 也很棒。
dynamic-nav.graphql
# import DynamicNavFragment from '../Partials/dynamic-nav-fields.graphql'
query DynamicNav(
$idHead: ID!
$idTypeHead: WordpressMenuNodeIdTypeEnum!
$idFoot: ID!
$idTypeFoot: WordpressMenuNodeIdTypeEnum!
) {
Header: wordpress {
menu(id: $idHead, idType: $idTypeHead) {
menuItems(where: { parentId: 0 }) {
edges {
node {
...DynamicNavFragment
childItems {
edges {
node {
...DynamicNavFragment
childItems {
edges {
node {
...DynamicNavFragment
}
}
}
}
}
}
}
}
}
}
}
Footer: wordpress {
menu(id: $idFoot, idType: $idTypeFoot) {
menuItems(where: { parentId: 0 }) {
edges {
node {
...DynamicNavFragment
childItems {
edges {
node {
...DynamicNavFragment
}
}
}
}
}
}
}
}
}
正在使用的片段是
dynamic-nav-fields.graphql
fragment DynamicNavFragment on WordpressMenuItem {
id
label
path
parentId
}
这一切都集中在一个全局 layout.tsx 组件中。我将在下面包含一个冗长的无头导航组件，但那是因为它有 3 层深，带有动态子子锚

从useDynamicNavQuery 函数注入数据的HeadlessNavbar 组件在此处映射。我一直想把它分开，但这有点痛苦。
