开始使用 Svelte

¥Getting Started with Svelte

🧹 删除了集成指南

Strapi 文档团队专注于改进 Strapi 5 核心体验的文档。我们将在未来 6 个月内发布许多更改，请密切关注👀。

¥The Strapi Documentation team focuses on improving the documentation for Strapi 5's core experience. We will release many changes in the next 6 months, so please keep an eye out 👀.

因此，当前页面现在仅处于维护模式，可能未完全与 Strapi 5 保持同步，并且很快将从 docs.strapi.io 中删除并移至 Strapi 的 集成页面。

¥As a result, the present page is now in maintenance mode only, might not be fully up-to-date with Strapi 5, and will soon be removed from docs.strapi.io and moved to Strapi's integrations page.

同时，如果你想帮助我们改进此页面，请随时 contribute 到文档的 GitHub 存储库。

¥In the meantime, if you want to help us improve this page, please feel free to contribute to the documentation's GitHub repository.

本集成指南遵循 快速入门指南。你应该能够通过浏览 URL http://localhost:1337/api/restaurants 使用该 API。

¥This integration guide follows the Quick Start Guide. You should be able to consume the API by browsing the URL http://localhost:1337/api/restaurants.

如果你尚未阅读快速入门指南，则使用 Svelte 请求 Strapi API 的方式将保持不变，只是你不会获取相同的内容。

¥If you haven't gone through the Quick Start Guide, the way you request a Strapi API with Svelte remains the same except that you will not fetch the same content.

创建一个 Svelte 应用​

¥Create a Svelte app

首先，通过在命令行接口 (CLI) 中运行 npm install -g degit 来安装 Degit。

¥First, install Degit by running npm install -g degit in your command-line interface (CLI).

“Degit 制作 Git 存储库的副本并获取存储库中的最新提交。这是比使用 git clone 更有效的方法，因为我们不会下载整个 Git 历史记录。”

¥“Degit makes copies of Git repositories and fetches the latest commit in the repository. This is a more efficient approach than using git clone, because we’re not downloading the entire Git history.”

使用 webpack 创建一个基本的 Svelte 应用：

¥Create a basic Svelte application using webpack:

npx degit sveltejs/template svelte-app

使用 HTTP 客户端​

¥Use an HTTP client

许多 HTTP 客户端都可用，但在本文档中我们将使用 Axios 和 拿来。

¥Many HTTP clients are available but in this documentation we'll use Axios and Fetch.

yarn add axios

GET 请求你的集合类型​

¥GET Request your collection type

对 restaurant 集合类型执行 GET 请求以获取所有餐厅。

¥Execute a GET request on the restaurant collection type in order to fetch all your restaurants.

确保你激活了 restaurant 集合类型的 find 权限。

¥Be sure that you activated the find permission for the restaurant collection type.

Example GET request with axios
import axios from 'axios';

axios.get('http://localhost:1337/api/restaurants').then(response => {
  console.log(response);
});
Example response
[
  {
    "id": 1,
    "name": "Biscotte Restaurant",
    "description": "Welcome to Biscotte restaurant! Restaurant Biscotte offers a cuisine based on fresh, quality products, often local, organic when possible, and always produced by passionate producers.",
    "created_by": {
      "id": 1,
      "firstname": "Paul",
      "lastname": "Bocuse",
      "username": null
    },
    "updated_by": {
      "id": 1,
      "firstname": "Paul",
      "lastname": "Bocuse",
      "username": null
    },
    "created_at": "2020-07-31T11:37:16.964Z",
    "updated_at": "2020-07-31T11:37:16.975Z",
    "categories": [
      {
        "id": 1,
        "name": "French Food",
        "created_by": 1,
        "updated_by": 1,
        "created_at": "2020-07-31T11:36:23.164Z",
        "updated_at": "2020-07-31T11:36:23.172Z"
      }
    ]
  }
]

示例​

¥Example

./src/App.svelte

<script>
import { onMount } from 'svelte';
import axios from 'axios'

let restaurants = [];
let error = null

onMount(async () => {
	try {
		const res = await axios.get('http://localhost:1337/api/restaurants');
		restaurants = res.data.data
	} catch (e) {
		error = e
	}
});

</script>

{#if error !== null}
  {error}
{:else}
  <ul>
  {#each restaurants as restaurant}
    <li>
  		{restaurant.attributes.name}
    </li>
  {/each}
  </ul>
{/if}

POST 请求你的集合类型​

在此示例中，已创建 japanese 类别，其 ID 为：3.

¥In this example a japanese category has been created which has the id: 3.

Example POST request with axios
import axios from 'axios';

axios
  .post('http://localhost:1337/api/restaurants', {
