# --description--
|
||
|
||
构建一个 JavaScript 的全栈应用,在功能上与这个应用相似: <https://exercise-tracker.freecodecamp.rocks/>。 可以采用下面的一种方式完成这个挑战:
|
||
|
||
- 克隆 [GitHub 仓库](https://github.com/freeCodeCamp/boilerplate-project-exercisetracker/) 并在本地完成你的项目。
|
||
- 使用[我们的 Replit 初始化项目](https://replit.com/github/freeCodeCamp/boilerplate-project-exercisetracker)来完成你的项目。
|
||
- 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。
|
||
|
||
# --hints--
|
||
|
||
提交自己的项目,而不是示例的 URL。
|
||
|
||
```js
|
||
(getUserInput) => {
|
||
const url = getUserInput('url');
|
||
assert(
|
||
!/.*\/exercise-tracker\.freecodecamp\.rocks/.test(getUserInput('url'))
|
||
);
|
||
};
|
||
```
|
||
|
||
可以将表单里的 `username` 通过 `POST` 请求发送到 `/api/users`,以创建一个新的用户。 返回的响应内容是一个带有 `username` 和 `_id` 的对象
|
||
|
||
```js
|
||
async (getUserInput) => {
|
||
const url = getUserInput('url');
|
||
const res = await fetch(url + '/api/users', {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `username=fcc_test_${Date.now()}`.substr(0, 29)
|
||
});
|
||
if (res.ok) {
|
||
const { _id, username } = await res.json();
|
||
assert.exists(_id);
|
||
assert.exists(username);
|
||
} else {
|
||
throw new Error(`${res.status} ${res.statusText}`);
|
||
}
|
||
};
|
||
```
|
||
|
||
可以发送 `GET` 请求到 `/api/users`,以获取一个所有用户的数组, 数组里的每个元素都是一个包含 `username` 和 `_id` 的用户对象。
|
||
|
||
```js
|
||
async (getUserInput) => {
|
||
const url = getUserInput('url');
|
||
const res = await fetch(url + '/api/users');
|
||
if (res.ok) {
|
||
const data = await res.json();
|
||
assert.isArray(data);
|
||
assert.isString(data[0].username);
|
||
assert.isString(data[0]._id);
|
||
} else {
|
||
throw new Error(`${res.status} ${res.statusText}`);
|
||
}
|
||
};
|
||
```
|
||
|
||
你能用表单里的 `description`、`duration` 和 `date`(可选)发送 `POST` 请求到 `/api/users/:_id/exercises`。 如果没有传入 date,默认采用当前日期。 响应内容是包含 exercise 表单内容的 user 对象。
|
||
|
||
```js
|
||
async (getUserInput) => {
|
||
const url = getUserInput('url');
|
||
const res = await fetch(url + '/api/users', {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `username=fcc_test_${Date.now()}`.substr(0, 29)
|
||
});
|
||
if (res.ok) {
|
||
const { _id, username } = await res.json();
|
||
const expected = {
|
||
username,
|
||
description: 'test',
|
||
duration: 60,
|
||
_id,
|
||
date: 'Mon Jan 01 1990'
|
||
};
|
||
const addRes = await fetch(url + `/api/users/${_id}/exercises`, {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `description=${expected.description}&duration=${expected.duration}&date=1990-01-01`
|
||
});
|
||
if (addRes.ok) {
|
||
const actual = await addRes.json();
|
||
assert.deepEqual(actual, expected);
|
||
} else {
|
||
throw new Error(`${addRes.status} ${addRes.statusText}`);
|
||
}
|
||
} else {
|
||
throw new Error(`${res.status} ${res.statusText}`);
|
||
}
|
||
};
|
||
```
|
||
|
||
可以发送 `GET` 请求到 `/api/users/:_id/logs`,以获取任何用户的完整 exercise 日志。 响应内容是一个 user 对象,它带有一个 `log` 属性,该属性的值是所有被添加的 exercises 表单记录组成的数组, 每一个 log 数组里的元素应该是一个含有 `description`、`duration` 和 `date` 等属性的对象。
|
||
|
||
```js
|
||
async (getUserInput) => {
|
||
const url = getUserInput('url');
|
||
const res = await fetch(url + '/api/users', {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `username=fcc_test_${Date.now()}`.substr(0, 29)
|
||
});
|
||
if (res.ok) {
|
||
const { _id, username } = await res.json();
|
||
const expected = {
|
||
username,
|
||
description: 'test',
|
||
duration: 60,
|
||
_id,
|
||
date: new Date().toDateString()
|
||
};
|
||
const addRes = await fetch(url + `/api/users/${_id}/exercises`, {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `description=${expected.description}&duration=${expected.duration}`
|
||
});
|
||
if (addRes.ok) {
|
||
const logRes = await fetch(url + `/api/users/${_id}/logs`);
|
||
if (logRes.ok) {
|
||
const { log } = await logRes.json();
|
||
assert.isArray(log);
|
||
assert.equal(1, log.length);
|
||
} else {
|
||
throw new Error(`${logRes.status} ${logRes.statusText}`);
|
||
}
|
||
} else {
|
||
throw new Error(`${addRes.status} ${addRes.statusText}`);
|
||
}
|
||
} else {
|
||
throw new Error(`${res.status} ${res.statusText}`);
|
||
}
|
||
};
|
||
```
|
||
|
||
用户日志请求(`/api/users/:_id/logs`)返回一个带有 `count` 属性的对象,该属性反映 exercises 表单的成功提交次数(译者注:即 log 属性元素的个数)。
|
||
|
||
```js
|
||
async (getUserInput) => {
|
||
const url = getUserInput('url');
|
||
const res = await fetch(url + '/api/users', {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `username=fcc_test_${Date.now()}`.substr(0, 29)
|
||
});
|
||
if (res.ok) {
|
||
const { _id, username } = await res.json();
|
||
const expected = {
|
||
username,
|
||
description: 'test',
|
||
duration: 60,
|
||
_id,
|
||
date: new Date().toDateString()
|
||
};
|
||
const addRes = await fetch(url + `/api/users/${_id}/exercises`, {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `description=${expected.description}&duration=${expected.duration}`
|
||
});
|
||
if (addRes.ok) {
|
||
const logRes = await fetch(url + `/api/users/${_id}/logs`);
|
||
if (logRes.ok) {
|
||
const { count } = await logRes.json();
|
||
assert(count);
|
||
} else {
|
||
throw new Error(`${logRes.status} ${logRes.statusText}`);
|
||
}
|
||
} else {
|
||
throw new Error(`${addRes.status} ${addRes.statusText}`);
|
||
}
|
||
} else {
|
||
throw new Error(`${res.status} ${res.statusText}`);
|
||
}
|
||
};
|
||
```
|
||
|
||
可以把 `from`、`to` 和 `limit` 参数添加到一个 `/api/users/:_id/logs` 请求,以查询该用户的部分 exercise 表单提交记录, `from` 和 `to` 是 `yyyy-mm-dd` 形式的日期, `limit` 是希望返回的 log 数量。
|
||
|
||
```js
|
||
async (getUserInput) => {
|
||
const url = getUserInput('url');
|
||
const res = await fetch(url + '/api/users', {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `username=fcc_test_${Date.now()}`.substr(0, 29)
|
||
});
|
||
if (res.ok) {
|
||
const { _id, username } = await res.json();
|
||
const expected = {
|
||
username,
|
||
description: 'test',
|
||
duration: 60,
|
||
_id,
|
||
date: new Date().toDateString()
|
||
};
|
||
const addExerciseRes = await fetch(url + `/api/users/${_id}/exercises`, {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `description=${expected.description}&duration=${expected.duration}&date=1990-01-01`
|
||
});
|
||
const addExerciseTwoRes = await fetch(url + `/api/users/${_id}/exercises`, {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
||
body: `description=${expected.description}&duration=${expected.duration}&date=1990-01-02`
|
||
});
|
||
if (addExerciseRes.ok && addExerciseTwoRes.ok) {
|
||
const logRes = await fetch(
|
||
url + `/api/users/${_id}/logs?from=1989-12-31&to=1990-01-03`
|
||
);
|
||
if (logRes.ok) {
|
||
const { log } = await logRes.json();
|
||
assert.isArray(log);
|
||
assert.equal(2, log.length);
|
||
} else {
|
||
throw new Error(`${logRes.status} ${logRes.statusText}`);
|
||
}
|
||
const limitRes = await fetch(
|
||
url + `/api/users/${_id}/logs?limit=1`
|
||
);
|
||
if (limitRes.ok) {
|
||
const { log } = await limitRes.json();
|
||
assert.isArray(log);
|
||
assert.equal(1, log.length);
|
||
} else {
|
||
throw new Error(`${limitRes.status} ${limitRes.statusText}`);
|
||
}
|
||
} else {
|
||
throw new Error(`${res.status} ${res.statusText}`);
|
||
}
|
||
} else {
|
||
throw new Error(`${res.status} ${res.statusText}`);
|
||
}
|
||
};
