无法从 Strapi API 获取数据到 next.js 前端 [英] Can't fetch data from Strapi API to next.js frontend

问题描述

我尝试过使用 Strapi 和 next.js 来制作博客网站.这是前端代码的next.js

从next/head"导入头部从'../styles/Home.module.css' 导入样式导出默认函数首页({帖子}){返回 (<div>{帖子&&post.map((posts) => (<div key={post.id}><h2>{posts.title}</h2>

))}

);}导出异步函数 getstaticProps() {//从我们的API获取帖子const res = await fetch("http://localhost:1337/posts");const 帖子 = 等待 res.json();返回 {道具:{帖子}，};}

这里是 Strapi API Json 数据

[{身份证":1，"title": "大家好","slug": "大家好","content": "大家好.",users_permissions_user":{身份证":4，"username": "tanha","email": "[e-mail]","提供者": "本地",确认":真实，阻止":假，角色":1，"created_at": "2021-03-12T06:02:44.726Z","updated_at": "2021-03-12T06:03:54.507Z"},"published_at": "2021-03-11T19:37:02.117Z","created_at": "2021-03-11T19:36:46.663Z","updated_at": "2021-03-12T11:48:57.275Z"}]

这里有什么问题?我尝试过，但在这里没有发现任何错误.但是无法获取数据到前端显示.

解决方案

getstaticProps 应该在不同的情况下 ->getStaticProps，除此之外你的代码看起来还不错.

I'm tried strapi and next.js to make a blog site. Here is next.js for frontend code

import Head from 'next/head'
import styles from '../styles/Home.module.css'

export default function Home({ posts }) {

  return (
    <div>
      {posts && 
      
      posts.map((posts) => (

        <div key={post.id}>
            <h2>{posts.title}</h2>
        </div>
      ))}
    </div>
  );
}



export async function getstaticProps() {

  //get post from our API

  const res = await fetch("http://localhost:1337/posts");
  const posts = await res.json();

  return {
    props: { posts },
  };

}

and Here is Strapi API Json data

[
{
"id": 1,
"title": "Hello Everyone",
"slug": "hello-everyone",
"content": "Hello All.",
"users_permissions_user": {
"id": 4,
"username": "tanha",
"email": "[e-mail]",
"provider": "local",
"confirmed": true,
"blocked": false,
"role": 1,
"created_at": "2021-03-12T06:02:44.726Z",
"updated_at": "2021-03-12T06:03:54.507Z"
},
"published_at": "2021-03-11T19:37:02.117Z",
"created_at": "2021-03-11T19:36:46.663Z",
"updated_at": "2021-03-12T11:48:57.275Z"
}
]

What is the problem in here? I was tried but found no errors in here. But can't fetch data into frontend to show.

解决方案

getstaticProps should be in different case -> getStaticProps, other than that your code looks fine.
