python爬虫竟然被小伙用来算命

前言

相信在日常生活中，平常大家聚在一起总会聊聊天，特别是女生(有冒犯到doge)非常喜欢聊星座，这个男生什么星座呀，那个男生什么星座呀…今天我就来满足各位的需求，通过爬虫来知晓上天的安排：

开搞！

1.网站分析

第一步呢，咋们先打开这个网站：https://www.horoscope.com/us/index.aspx

大家就能看到这个页面了

我们今天呢，就先做一个通过星座来得知三天的运势的小玩意，

这里有十二个星座，我点了第一个和第二个进去，也就是白羊座和金牛座：

就会发现一个规律

通过观察网址的链接，我这张丑脸泛起了灿烂的笑容。

也就是说，https://www.horoscope.com/us/horoscopes/general/是每个星座都共有的一段网址，

horoscope-general-daily-today.aspx?sign=1

我们只需改变today和sign={}对应的值就可以获取到每个星座对应的网址了

https://www.horoscope.com/us/horoscopes/general/horoscope-general-daily-today.aspx?sign=1

我们再打开金牛座的昨天的运势，发现daily-后面变成了tomorrow

我们这里只获取三天的，也就是昨天，今天，明天，我们只需在控制台输入需要查询的日期就行了。

2.获取内容

从图片我们可以得到我们所需的内容，这个是很基础的爬虫了，没有反爬，我们直接上代码了。

3.代码

from bs4 import BeautifulSoup
import requests

def horoscope(zodiac_sign: int, day: str) -> str:
   url = (
       "https://www.horoscope.com/us/horoscopes/general/"
       f"horoscope-general-daily-{day}.aspx?sign={zodiac_sign}"
   )#获取需要查询的星座的链接
   soup = BeautifulSoup(requests.get(url).content, "html.parser")
   return soup.find("div", class_="main-horoscope").p.text#返回得到的内容——来自上天的指示

如果有小伙伴不知道自己的星座怎么办呢，所以我们就还需要一个函数去查询星座：

def check_sign():#得到星座
   your_birth_day = input("输入您的生日的日期> ")
   your_birth_month = input("输入你生日的月份> ")
   if (int(your_birth_month) == 12 and int(your_birth_day) >= 22) or (
       int(your_birth_month) == 1 and int(your_birth_day) <= 19
   ):
       sign = "Capricorn"
   elif (int(your_birth_month) == 1 and int(your_birth_day) >= 20) or (
       int(your_birth_month) == 2 and int(your_birth_day) <= 17
   ):
       sign = "Aquarium"
   elif (int(your_birth_month) == 2 and int(your_birth_day) >= 18) or (
       int(your_birth_month) == 3 and int(your_birth_day) <= 19
   ):
       sign = "Pices"
   elif (int(your_birth_month) == 3 and int(your_birth_day) >= 20) or (
       int(your_birth_month) == 4 and int(your_birth_day) <= 19
   ):
       sign = "Aries"
   elif (int(your_birth_month) == 4 and int(your_birth_day) >= 20) or (
       int(your_birth_month) == 5 and int(your_birth_day) <= 20
   ):
       sign = "Taurus"
   elif (int(your_birth_month) == 5 and int(your_birth_day) >= 21) or (
       int(your_birth_month) == 6 and int(your_birth_day) <= 20
   ):
       sign = "Gemini"
   elif (int(your_birth_month) == 6 and int(your_birth_day) >= 21) or (
       int(your_birth_month) == 7 and int(your_birth_day) <= 22
   ):
       sign = "Cancer"
   elif (int(your_birth_month) == 7 and int(your_birth_day) >= 23) or (
       int(your_birth_month) == 8 and int(your_birth_day) <= 22
   ):
       sign = "Leo"
   elif (int(your_birth_month) == 8 and int(your_birth_day) >= 23) or (
       int(your_birth_month) == 9 and int(your_birth_day) <= 22
   ):
       sign = "Virgo"
   elif (int(your_birth_month) == 9 and int(your_birth_day) >= 23) or (
       int(your_birth_month) == 10 and int(your_birth_day) <= 22
   ):
       sign = "Libra"
   elif (int(your_birth_month) == 10 and int(your_birth_day) >= 23) or (
       int(your_birth_month) == 11 and int(your_birth_day) <= 21
   ):
       sign = "Scorpio"
   elif (int(your_birth_month) == 11 and int(your_birth_day) >= 22) or (
       int(your_birth_month) == 12 and int(your_birth_day) <= 21
   ):
       sign = "Sagittarius"

return sign

4.实操

怎么样？很有趣吧，当然网站有很多的用处，等以后我会继续更新，实现更多的好玩的功能。

5.代码整合

from bs4 import BeautifulSoup
import requests

def check_sign():
   your_birth_day = input("输入您的生日的日期> ")
   your_birth_month = input("输入你生日的月份> ")
   if (int(your_birth_month) == 12 and int(your_birth_day) >= 22) or (
       int(your_birth_month) == 1 and int(your_birth_day) <= 19
   ):
       sign = "Capricorn"
   elif (int(your_birth_month) == 1 and int(your_birth_day) >= 20) or (
       int(your_birth_month) == 2 and int(your_birth_day) <= 17
   ):
       sign = "Aquarium"
   elif (int(your_birth_month) == 2 and int(your_birth_day) >= 18) or (
       int(your_birth_month) == 3 and int(your_birth_day) <= 19
   ):
       sign = "Pices"
   elif (int(your_birth_month) == 3 and int(your_birth_day) >= 20) or (
       int(your_birth_month) == 4 and int(your_birth_day) <= 19
   ):
       sign = "Aries"
   elif (int(your_birth_month) == 4 and int(your_birth_day) >= 20) or (
       int(your_birth_month) == 5 and int(your_birth_day) <= 20
   ):
       sign = "Taurus"
   elif (int(your_birth_month) == 5 and int(your_birth_day) >= 21) or (
       int(your_birth_month) == 6 and int(your_birth_day) <= 20

       sign = "Gemini"
   elif (int(your_birth_month) == 6 and int(your_birth_day) >= 21) or (
       int(your_birth_month) == 7 and int(your_birth_day) <= 22
   ):
       sign = "Cancer"
   elif (int(your_birth_month) == 7 and int(your_birth_day) >= 23) or (
       int(your_birth_month) == 8 and int(your_birth_day) <= 22
   ):
       sign = "Leo"

   elif (int(your_birth_month) == 10 and int(your_birth_day) >= 23) or (
       int(your_birth_month) == 11 and int(your_birth_day) <= 21
   ):
       sign = "Scorpio"
   elif (int(your_birth_month) == 11 and int(your_birth_day) >= 22) or (
       int(your_birth_month) == 12 and int(your_birth_day) <= 21
   ):
       sign = "Sagittarius"
