|
|
|
|
2021-02-16 13:01:20 -08:00
|
|
|
- 克隆 [this GitHub repo](https://github.com/freeCodeCamp/boilerplate-project-timestamp/) 并在本地完成项目。
|
2021-05-12 21:25:58 +05:30
|
|
|
- 使用[我们的 Replit 初始化项目](https://replit.com/github/freeCodeCamp/boilerplate-project-timestamp)来完成你的项目。
|
2021-02-16 13:01:20 -08:00
|
|
|
- 使用你选择的网站生成器来完成项目, 并确保包含了我们 GitHub 仓库的所有文件。

|
|
|
当完成本项目,请确认有一个正常运行的 demo 可以公开访问。 然后将 URL 提交到 `Solution Link` 中。 此外,还可以将项目的源码提交到 `GitHub Link` 中。

向 `/api/:date?` 发送一个带有有效日期的请求,应该很快(在几毫秒内)返回一个 JSON 对象,在这个 JSON 对象内有一个包含输入日期的 Unix 时间戳的 `unix` 键。

向 `/api/1451001600000` 发送请求,应该返回 `{ unix: 1451001600000, utc: "Fri, 25 Dec 2015 00:00:00 GMT" }`。
