使用imageSharp regex和gatsby的graphQL中出现错误 [英] error in graphQL using imageSharp regex with gatsby
问题描述
我正在使用gatsby创建一个简单的博客.当我尝试搜索特定图像时,出现来自graphql的错误.我有以下配置:
I'm using gatsby to create a simple blog. When I try to search for an specific image, I get an error from graphql. I have the following configs:
已安装"gatsby-image": "^1.0.55"
graphql`
query MainLayoutQuery {
heroImage: imageSharp(id: { regex: "/hero.jpg/" }) {
id
sizes(quality: 100) {
base64
tracedSVG
aspectRatio
src
srcSet
srcWebp
srcSetWebp
sizes
originalImg
originalName
}
}
}
`
当我在graphql ui中运行该查询时,我得到:
when I run that query in graphql ui I get:
{
"errors": [
{
"message": "Cannot read property 'id' of undefined",
"locations": [
{
"line": 31,
"column": 3
}
],
"path": [
"heroImage"
]
}
],
"data": {
"heroImage": null
}
}
但是,如果我在不使用正则表达式的情况下运行相同的查询,则效果很好:
But, if I run the same query without the regex, it works fine:
{
heroImage: imageSharp {
id
sizes(quality: 100) {
base64
tracedSVG
aspectRatio
src
srcSet
srcWebp
srcSetWebp
sizes
originalImg
originalName
}
}
}
当然,它会带来它可以访问的第一张图片
Of course, it brings the first image it has access to
"data": {
"heroImage": {
"id": "/Users/marcosrios/dev/workspace/atravesando-todo-limite/src/posts/2018-08-25-tengo-miedo/cover.png absPath of file >> ImageSharp"
}
}
推荐答案
您正在使用哪个版本的盖茨比?如果v2
,您需要编辑查询,因为已经进行了更改:
https://next. gatsbyjs.org/docs/migrating-from-v1-to-v2/#dont-query-nodes-by-id
Which version of Gatsby are you using? If v2
you need to edit your query as there has been changes:
https://next.gatsbyjs.org/docs/migrating-from-v1-to-v2/#dont-query-nodes-by-id
您的查询将如下所示:
graphql`
query MainLayoutQuery {
heroImage: imageSharp(fluid: { originalName: { regex: "/hero.jpg/" } }) {
id
fluid(quality: 100) {
base64
tracedSVG
aspectRatio
src
srcSet
srcWebp
srcSetWebp
sizes
originalImg
originalName
}
}
}
