--description--
构建一个功能类似于 https://fuschia-custard.glitch.me/ 的 JavaScript 全栈应用。
在开发这个项目时,我们推荐你在 Glitch 上编码。编码完成之后,你可以把应用主页的链接复制到屏幕的输入框中,测试你的代码是否能通过项目需求。当然你也可以基于其他的平台来完成自己的项目,只要提供一个公开的主页便于我们测试就行。
参考示例:你可以通过 这个链接 访问在 Glitch 上的项目,或者从 GitHub 上 clone 这个仓库的代码。如果你使用 Glitch,请记住将项目链接保存到妥当的地方。
--hints--
提供独立的项目, 而不是例程 url.
(getUserInput) => {
const url = getUserInput('url');
assert(
!new RegExp('.*/fuschia-custard.glitch.me.*').test(getUserInput('url'))
);
};
通过指定 /api/exercise/new-user
的 username 参数来创建用户, 并且返回一个具有 username 和 _id 的对象。
async (getUserInput) => {
const url = getUserInput('url');
const res = await fetch(url + '/api/exercise/new-user', {
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} ${res.statusText}`);
}
};
通过指定 api/exercise/users
的参数为创建用户时相同的信息,来获取到一个用户的数组。
async (getUserInput) => {
const url = getUserInput('url');
const res = await fetch(url + '/api/exercise/users');
if (res.ok) {
const data = await res.json();
assert.isArray(data);
} else {
throw new Error(`${res.status} ${res.statusText}`);
}
};
通过指定 /api/exercise/add
的 userId、description、duration 和 date(可选)参数, 去添加一条练习记录。 当没有传入 date 的时候,默认采用当前日期。 应用程序将返回添加了练习字段的用户对象。
async (getUserInput) => {
const url = getUserInput('url');
const res = await fetch(url + '/api/exercise/new-user', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: `username=fcc_test_${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/exercise/add', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: `userId=${_id}&description=${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} ${res.statusText}`);
}
};
通过指定 /api/exercise/log
的 userId 参数,可以获取任意用户的练习日志和总的练习次数。
async (getUserInput) => {
const url = getUserInput('url');
const res = await fetch(url + '/api/exercise/new-user', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: `username=fcc_test_${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/exercise/add', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: `userId=${_id}&description=${expected.description}&duration=${expected.duration}`
});
if (addRes.ok) {
const logRes = await fetch(url + `/api/exercise/log?userId=${_id}`);
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} ${res.statusText}`);
}
};
我还可以通过传递可选参数 from & to 或 limit 来检索任何用户的部分日志。(日期格式如: yyyy-mm-dd, limit = int)
async (getUserInput) => {
const url = getUserInput('url');
const res = await fetch(url + '/api/exercise/new-user', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: `username=fcc_test_${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/exercise/add', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: `userId=${_id}&description=${expected.description}&duration=${expected.duration}&date=1990-01-01`
});
const addExerciseTwoRes = await fetch(url + '/api/exercise/add', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: `userId=${_id}&description=${expected.description}&duration=${expected.duration}&date=1990-01-02`
});
if (addExerciseRes.ok && addExerciseTwoRes.ok) {
const logRes = await fetch(
url + `/api/exercise/log?userId=${_id}&from=1989-12-31&to=1990-01-03`
);
if (logRes.ok) {
const { log } = await logRes.json();
assert.isArray(log);
assert.equal(2, log.length);
} else {
throw new Error(`${logRes.status} ${logRes.statusText}`);
}
const limitRes = await fetch(
url + `/api/exercise/log?userId=${_id}&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}`);
}
};
