手把手教你使用Python打造一款摸魚倒計時界面

大家好，我是吳老板。

前言

前段時間在微博看到一段摸魚人的倒計時模板，感覺還挺有趣的。

手把手教你使用Python打造一款摸魚倒計時界面

于是我用了一小時的時間寫了個頁面出來摸魚辦地址 (當然是摸魚的時間啦)。

模板是這樣的:

摸魚辦公室

【摸魚辦公室】今天是 2021-11-30 星期二

你好，摸魚人，工作再累，一定不要忘記摸魚哦 ! 有事沒事起身去茶水間去廊道去天臺走走，別老在工位上坐著。多喝點水，錢是老板的，但命是自己的 !

距離周末放假還有 2 天

距離元旦放假還有 3 天

距離過年放假還有 34 天

距離清明節放假還有 97 天

距離勞動節放假還有 123 天

距離端午節放假還有 156 天

距離中秋節放假還有 255 天

距離國慶節放假還有 276 天

由于前端是單頁面服務，直接擼一個原始的 html 網頁就行。
FastAPI 對于異步請求是一把好手、更輕、性能更佳。
掛上一層 Nginx 讓它看起來像那么回事兒。

實現過程

首先要知道、除了靜態文字之外的比如當前日期、距離節日放假的天數等都是動態返回的，我需要使用 Jinja2 模板進行動態綁定。
我應該把重點放在時間的處理上。
而且在這個模板中，有陽歷的節日，也是陰歷的節日，我需要轉換。

初始化一個 FastAPI 對象并聲明靜態頁面的模板目錄 (Jinja2Templates)

# -*- coding: utf-8 -*-
import datetime
from fastapi import FastAPI, Request
from fastapi.responses import HTMLResponse
from fastapi.templating import Jinja2Templates
from zhdate import ZhDate as lunar_date
app = FastAPI(
debug=False,
title="My API",
docs_url="/docs",
openapi_url=f"/openapi.json"
)
templates = Jinja2Templates(directory="templates")

可以看到的是我用到了 zhdate 這個庫、主要用于陰歷和陽歷之間的相互轉換。用法如下

today = datetime.date.today()
print(today.year, today.month, today.day)
print("大年時間: ", lunar_date(today.year+1, 1, 1).to_datetime().date())
print("端午時間: ", lunar_date(today.year, 5, 5).to_datetime().date())
print("中秋時間: ", lunar_date(today.year, 8, 15).to_datetime().date())
print("元旦時間: ", f"{today.year+1}-01-01")
print("清明時間: ", f"{today.year}-04-05")
print("勞動時間: ", f"{today.year}-05-01")
print("國慶時間: ", f"{today.year}-10-01")

我們可以梳理一下:

計算距離大年、元旦的天數時，要在年份上 +1
計算距離其他節日的天數時，要判斷天數差是否小于 0，如果是，則年份需要 +1，因為已經過去的節日對此沒有意義

distance_big_year = (lunar_date(today.year + 1, 1, 1).to_datetime().date() - today).days
distance_5_5 = (lunar_date(today.year, 5, 5).to_datetime().date() - today).days
distance_5_5 = distance_5_5 if distance_5_5 > 0 else (
lunar_date(today.year + 1, 5, 5).to_datetime().date() - today).days
distance_8_15 = (lunar_date(today.year, 8, 15).to_datetime().date() - today).days
distance_8_15 = distance_8_15 if distance_8_15 > 0 else (
lunar_date(today.year + 1, 8, 15).to_datetime().date() - today).days
distance_year = (datetime.datetime.strptime(f"{today.year + 1}-01-01", "%Y-%m-%d").date() - today).days
distance_4_5 = (datetime.datetime.strptime(f"{today.year}-04-05", "%Y-%m-%d").date() - today).days
distance_4_5 = distance_4_5 if distance_4_5 > 0 else (
datetime.datetime.strptime(f"{today.year + 1}-04-05", "%Y-%m-%d").date() - today).days
distance_5_1 = (datetime.datetime.strptime(f"{today.year}-05-01", "%Y-%m-%d").date() - today).days
distance_5_1 = distance_5_1 if distance_5_1 > 0 else (
datetime.datetime.strptime(f"{today.year + 1}-05-01", "%Y-%m-%d").date() - today).days
distance_10_1 = (datetime.datetime.strptime(f"{today.year}-10-01", "%Y-%m-%d").date() - today).days
distance_10_1 = distance_10_1 if distance_10_1 > 0 else (
datetime.datetime.strptime(f"{today.year + 1}-10-01", "%Y-%m-%d").date() - today).days

怎么樣? 我的命名足夠瘋狂吧。

接下來需要計算一下距離周末的天數。

def get_week_day(date):
week_day_dict = {
0: '星期一',
1: '星期二',
2: '星期三',
3: '星期四',
4: '星期五',
5: '星期六',
6: '星期天',
}
day = date.weekday()
return week_day_dict[day]
week_day_ = get_week_day(today)
print(f"今天是: {week_day_}") # 先獲取今天是星期幾

按照每周 5 個工作日計算，今天距離周末的天數就是

5 - today.weekday() # today.weekday() 今天距離周末

現在將所有的數據組裝起來

time_ = [
{"v_": distance_year, "title": "元旦"}, # 距離元旦
{"v_": distance_big_year, "title": "過年"}, # 距離過年
{"v_": distance_4_5, "title": "清明節"}, # 距離清明
{"v_": distance_5_1, "title": "勞動節"}, # 距離勞動
{"v_": distance_5_5, "title": "端午節"}, # 距離端午
{"v_": distance_8_15, "title": "中秋節"}, # 距離中秋
{"v_": distance_10_1, "title": "國慶節"}, # 距離國慶
]

至于為什么是 List 而不是 Dict，那是我需要做一個根據距離天數的排序，讓最先放假的節日放于最前面，這樣看起來會舒服得多。

time_ = sorted(time_, key=lambda x: x['v_'], reverse=False)

接下來要寫一個路由，將數據傳入到 html 頁面中去。

@app.get("/", response_class=HTMLResponse)
async def readme(request: Request):
return templates.TemplateResponse("readme.html",
{"request": request, "time_": time_, "now_": now_, "week_day_": week_day_})
