Dart 入门

¥Getting Started with Dart

🧹 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 Dart 请求 Strapi API 的方式将保持不变，只是你不获取相同的内容。

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

创建 Dart 文件​

¥Create a Dart file

确保你的计算机上有 已安装 Dart。

¥Be sure to have Dart installed on your computer.

take dart-app
touch main.dart

使用 HTTP 客户端​

¥Use an HTTP client

我们将使用 http 来发出 HTTP 请求。

¥We'll use http for making HTTP requests.

  • 创建一个包含以下内容的 pubspec.yaml 文件：

    ¥Create a pubspec.yaml file containing the following:

name: my_app
dependencies:
  http: ^0.12.2

  • 通过运行以下命令来安装依赖：

    ¥Install your dependencies by running the following command:

dart pub get

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
Map<String,String> headers = {
  'Content-Type':'application/json',
  'Accept': 'application/json'
};

var response = await http.get(
  'http://localhost:1337/restaurants',
  headers: headers
);

print(response.body)
