* fix typo

* fix typo

* undo change

* Corrected grammar mistake

Corrected a grammar mistake by removing a comma.

* update title

* Change APIs and Microservices certi title

* Update translations.json

* update title

* feat(curriculum): rename apis and microservices cert

* rename folder structure

* rename certificate

* rename learn Markdown

* apis-and-microservices -> back-end-development-and-apis

* fix: add development to front-end libraries (#42512)

* fix: added-the-word-Development-to-front-end-libraries

* fix/reverted changes that i made to package.json

* remove unwanted changes

* front-end-development-libraries changes

* rename backend certSlug and README

* update i18n folder names and keys

* test: add legacy path redirect tests

This uses serve.json from the client-config repo, since we currently use
that in production

* fix: create public dir before moving serve.json

* fix: add missing script

* refactor: collect redirect tests

* test: convert to cy.location for stricter tests

* rename certificate folder to 00-certificates

* change crowdin config to recognise new certificates location

* allow translations to be used

* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

--description--

构建一个 JavaScript 的全栈应用,在功能上与这个应用相似:https://timestamp-microservice.freecodecamp.rocks/。 可以采用下面的任意一种方式完成这个挑战:

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。

--hints--

提交自己的项目,而不是示例的 URL。

(getUserInput) => {
  assert(
    !/.*\/timestamp-microservice\.freecodecamp\.rocks/.test(getUserInput('url'))
  );
};

/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。

(getUserInput) =>
  $.get(getUserInput('url') + '/api/2016-12-25').then(
    (data) => {
      assert.equal(
        data.unix,
        1482624000000,
        'Should be a valid unix timestamp'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

/api/:date? 发送一个带有有效日期的请求,应该返回一个 JSON 对象,在这个 JSON 对象内有一个包含如 Thu, 01 Jan 1970 00:00:00 GMT 格式的输入日期的 utc 键。

(getUserInput) =>
  $.get(getUserInput('url') + '/api/2016-12-25').then(
    (data) => {
      assert.equal(
        data.utc,
        'Sun, 25 Dec 2016 00:00:00 GMT',
        'Should be a valid UTC date string'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

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

(getUserInput) =>
  $.get(getUserInput('url') + '/api/1451001600000').then(
    (data) => {
      assert(
        data.unix === 1451001600000 &&
          data.utc === 'Fri, 25 Dec 2015 00:00:00 GMT'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

程序能成功处理能被 new Date(date_string) 解析的日期。

(getUserInput) =>
  $.get(getUserInput('url') + '/api/05 October 2011').then(
    (data) => {
      assert(
        data.unix === 1317772800000 &&
          data.utc === 'Wed, 05 Oct 2011 00:00:00 GMT'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

如果传入的日期是无效的,将返回一个带有结构体 { error : "Invalid Date" } 的对象。

(getUserInput) =>
  $.get(getUserInput('url') + '/api/this-is-not-a-date').then(
    (data) => {
      assert.equal(data.error.toLowerCase(), 'invalid date');
    },
    (xhr) => {
      assert(xhr.responseJSON.error.toLowerCase() === 'invalid date');
    }
  );

如果传入的参数是空日期,将返回一个包含当前时间的 unix 键的 JSON 对象。

(getUserInput) =>
  $.get(getUserInput('url') + '/api').then(
    (data) => {
      var now = Date.now();
      assert.approximately(data.unix, now, 20000);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

如果传入的参数是空日期,将返回一个包含当前时间的 utc 键的 JSON 对象。

(getUserInput) =>
  $.get(getUserInput('url') + '/api').then(
    (data) => {
      var now = Date.now();
      var serverTime = new Date(data.utc).getTime();
      assert.approximately(serverTime, now, 20000);
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
