Strapi & Gatsby 图像问题

问题描述

我一直在遵循以下步骤：https://github.com/strapi/gatsby-source-strapi 由于 image >> publicURL 也不起作用，我重新安装了最新版本的 gatsby-source-strapi，以便能够获得 publicURL。这虽然通过本地文件...

这是我的 gatsby-config.js

module.exports = {
  plugins: [
    "gatsby-plugin-react-helmet",{
      resolve: `gatsby-source-filesystem`,options: {
        name: `images`,path: `${__dirname}/src/images`,},{
      resolve: "gatsby-source-strapi",options: {
        apiURL:  "http://localhost:1337",contentTypes: ["articles"],singleTypes: [`homepage`,`global`],queryLimit: 1000,"gatsby-plugin-postcss",],};

我的博客页面如下

import React from 'react';
import Footer from '../partials/Footer';
import Navbar from '../partials/Navbar';

import { StaticQuery,graphql } from 'gatsby';

const query = graphql`
  query {
    allStrapiArticles{
      edges {
        node {
          strapiId
          title
          description
          image {
            localFile {
              publicURL
            }
          }
        }
      }
    }
  }
`;

function Blog() {
  return (
    <div className="min-h-screen overflow-hidden">
        <Navbar />
      <div className="max-w-4xl mx-auto py-12 lg:py-16 ">
        <h2 className="text-3xl font-extrabold tracking-tight text-gray-900 sm:text-4xl">
          <span className="block">Coming soon!</span>
          <span className="block text-indigo-600">I am just learning stuff about headless CMS and will build a blog here with strapi.io. Hang in!</span>
        </h2>
      </div>
      <StaticQuery
        query={query}
        render={data => (
          <div className="p-10 grid grid-cols-1 sm:grid-cols-1 md:grid-cols-3 lg:grid-cols-3 xl:grid-cols-3 gap-5">
            {data.allStrapiArticles.edges.map(article => (
              <div className="rounded overflow-hidden shadow-lg">
                <li key={article.node.strapiId}>{article.node.title}</li>
                <img
                  class="w-10 h-10 object-cover object-center rounded-full"
                  src={article.node.image.localFile.publicURL}
                  alt="random user"
                />
              </div>
            ))}
          </div>
        )}
      />
    <Footer />
    </div>
  );
}
export default Blog;

错误：无法读取未定义的属性“publicURL”。不知何故 localfile 未定义......我的疑问

解决方法

根据：

页面不会在开发中显示：错误：无法读取属性“publicURL” 未定义。

images 是一个数组，所以它需要被访问为：

你试过了吗？

        {data.allStrapiArticles.edges.map(({ node:article })=> {
         return <div key={article.strapiId} className="rounded overflow-hidden shadow-lg">
            <li key={article.strapiId}>{article.title}</li>
            {article.image[0].localFile && 
            <img
              class="w-10 h-10 object-cover object-center rounded-full"
              src={article.image[0].localFile.publicURL}
              alt="random user"
            />}
          </div>
        })}

在可迭代变量的解构和别名中，我添加了 key 属性。

您似乎在某处有一些 undefined 图像，添加此条件 (article.image[0].localFile.publicURL) 只会在它可用时打印它。
