正如我看到的那样,在查询 contentfulBlogPost 时不再有 json 选项。我能够进行一些更改以从身体中获取所有内容,除了该帖子中的图像。
如果我在 GraphQL Playground 中进行了测试,我可以获得图像 id 和 url,仅此而已。
query {
allContentfulAsset {
edges {
node {
id
file {
url
}
}
}
}
}
我试图找到一个如何获取嵌入图像的示例,但没有运气......
import React from 'react'
import { graphql } from 'gatsby'
import { documentToReactComponents } from '@contentful/rich-text-react-renderer'
import Layout from '../components/layout'
export const query = graphql`
query($slug: String!) {
contentfulBlogPost(slug: {eq: $slug}) {
title
publishedDate(formatString: "MMMM Do, YYYY")
body {
raw
}
}
allContentfulAsset {
edges {
node {
id
file {
url
}
}
}
}
}
`
const Blog = (props) => {
const options = {
renderNode: {
"embedded-asset-block": (node) => {
const alt = node.data.title
const url = node.file.url
return <img alt={alt} src={url}/>
}
}
}
return (
<Layout>
<h1>{props.data.contentfulBlogPost.title}</h1>
<p>{props.data.contentfulBlogPost.publishedDate}</p>
{documentToReactComponents(JSON.parse(props.data.contentfulBlogPost.body.raw, options))}
</Layout>
)
}
export default Blog
插件:
...
'gatsby-plugin-sharp',
{
resolve: 'gatsby-transformer-remark',
options: {
plugins: [
'gatsby-remark-relative-images',
{
resolve: 'gatsby-remark-images-contentful',
options: {
maxWidth: 750,
linkImagesToOriginal: false
}
}
]
}
}
],
}
