我正在尝试通过 Gatsby 中的 GraphQL 获取我的模拟 JSON 数据。响应显示正确的数据,但也显示两个空对象。为什么会这样?
我正在使用gatsby-transformer.json
插件来查询我的数据并将gatsby-source-filesystem
转换器指向我的 json 文件。
categories.json 我要开始工作的模拟文件:)
{
"categories": [
{
"title": "DEZERTY",
"path": "/dezerty",
"categoryItems": [
{
"categoryName": "CUKRIKY",
"image": "../../../../static/img/dessertcategories/cukriky.jpg"
},
{
"categoryName": "NAHODNE",
"image": "../../../../static/img/dessertcategories/nahodne.jpg"
},
]
},
{
"title": "CANDY BAR",
"path": "/candy-bar",
"categoryItems": [
{
"categoryName": "CHEESECAKY",
"image": "../../../../static/img/dessertcategories/cheesecaky.jpg"
},
{
"categoryName": "BEZLEPKOVÉ TORTY",
"image": "../../../../static/img/dessertcategories/bezlepkove-torty.jpg"
},
]
}
]
}
GraphiQL 中的 GraphQL 查询
query Collections {
allMockJson {
edges {
node {
categories {
categoryItems {
categoryName
image
}
title
path
}
}
}
}
}
GraphiQL 给我的响应
{
"data": {
"allMockJson": {
"edges": [
{
"node": {
"categories": null
}
},
{
"node": {
"categories": null
}
},
{
"node": {
"categories": [
{
"categoryItems": [
{
"categoryName": "CHEESECAKY",
"image": "../../../../static/img/dessertcategories/cheesecaky.jpg"
},
{
"categoryName": "BEZLEPKOVÉ TORTY",
"image": "../../../../static/img/dessertcategories/bezlepkove-torty.jpg"
}
],
"title": "DEZERTY",
"path": "/dezerty"
},
{
"categoryItems": [
{
"categoryName": "CUKRIKY",
"image": "../../../../static/img/dessertcategories/CUKRIKY.jpg"
},
{
"categoryName": "NAHODNE",
"image": "../../../../static/img/dessertcategories/NAHODNE.jpg"
}
],
"title": "CANDY BAR",
"path": "/candy-bar"
}
]
}
}
]
}
}
}
我只希望得到DEZERTY和CANDY BAR部分。为什么有空类别,我该如何解决?
