Shaun Hamilton c2a11ad00d feat: add 'back/front end' in curriculum (#42596)
* chore: rename APIs and Microservices to include "Backend" (#42515)

* fix typo

* fix typo

* undo change

* Corrected grammar mistake

Corrected a grammar mistake by removing a comma.

* change APIs and Microservices cert title

* 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

* update backend meta

* update i18n langs and cypress test

* 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://url-shortener-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。

--instructions--

提示: 请使用 body parsing 中间件来处理 POST 请求, 也可以使用 dns 核心模块中的 dns.lookup(host, cb) 函数验证提交的 URL。

--hints--

提交自己的项目,而不是示例的 URL。

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

可以通过 POST 请求给 /api/shorturl 发送一个 URL并返回一个带有 original_urlshort_url 属性的 JSON 响应。 例如:{ original_url : 'https://freeCodeCamp.org', short_url : 1}

async (getUserInput) => {
  const url = getUserInput('url');
  const urlVariable = Date.now();
  const fullUrl = `${url}/?v=${urlVariable}`
  const res = await fetch(url + '/api/shorturl', {
    method: 'POST',
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    body: `url=${fullUrl}`
  });
  if (res.ok) {
    const { short_url, original_url } = await res.json();
    assert.isNotNull(short_url);
    assert.strictEqual(original_url, `${url}/?v=${urlVariable}`);
  } else {
    throw new Error(`${res.status} ${res.statusText}`);
  }
};

当访问 /api/shorturl/<short_url> 时, 将重定向到原来的 URL。

async (getUserInput) => {
  const url = getUserInput('url');
  const urlVariable = Date.now();
  const fullUrl = `${url}/?v=${urlVariable}`
  let shortenedUrlVariable;
  const postResponse = await fetch(url + '/api/shorturl', {
    method: 'POST',
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    body: `url=${fullUrl}`
  });
  if (postResponse.ok) {
    const { short_url } = await postResponse.json();
    shortenedUrlVariable = short_url;
  } else {
    throw new Error(`${postResponse.status} ${postResponse.statusText}`);
  }
  const getResponse = await fetch(
    url + '/api/shorturl/' + shortenedUrlVariable
  );
  if (getResponse) {
    const { redirected, url } = getResponse;
    assert.isTrue(redirected);
    assert.strictEqual(url,fullUrl);
  } else {
    throw new Error(`${getResponse.status} ${getResponse.statusText}`);
  }
};

如果传入一个没有遵循如 http://www.example.com 的无效 URL则返回包含 { error: 'invalid url' } 的 JSON 响应。

async (getUserInput) => {
  const url = getUserInput('url');
  const res = await fetch(url + '/api/shorturl', {
    method: 'POST',
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    body: `url=ftp:/john-doe.org`
  });
  if (res.ok) {
    const { error } = await res.json();
    assert.isNotNull(error);
    assert.strictEqual(error.toLowerCase(), 'invalid url');
  } else {
    throw new Error(`${res.status} ${res.statusText}`);
  }
};
