Python爬取IP归属地信息及各个地区天气信息

一、实现样式

ip查询
weather

二、核心点

1、语言：Python、HTML，CSS
2、python web框架 Flask
3、三方库：requests、xpath
4、爬取网站：https://ip138.com/
5、文档结构

三、代码

ipquery.py

import requests
from lxml import etree
# 请求user-agent
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36'}

def getIpInfo(ip):
    ipurl = f"https://ip138.com/iplookup.php?ip={ip}&action=2"
    res = requests.get(ipurl,headers = headers)
    e = etree.HTML(res.text)
    ip = e.xpath("//div[@class='caption']//h1//text()")
    ipinfo = e.xpath("//div[@class='table-box']//tbody//tr//td[2]//text()")
    ipinfo.append(ip[0])
    return ipinfo

searchWeather.py

import requests
from lxml import etree,html
import re

# 请求user-agent
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36'}
def getWeather(location):
    weatherUrl = f"https://www.wentian123.com/search/?location={location}"
    res = requests.get(weatherUrl,headers = headers)
    e = etree.HTML(res.text)
    weather = e.xpath("//table//tbody//td//text()")
    
    #处理数据
    # 去除'\n'
    weathernew = [x.strip() for x in weather]
    # 去掉空字符串''
    while ''  in weathernew:
        weathernew.remove('')
    # print(weathernew)
    # 数据分组 6个一组
    weatherInfo = [weathernew[i:i+6] for i in range(0,len(weathernew),6)]
    return weatherInfo

query.py

from flask import Flask,render_template,request

from ipquery.ipquery import getIpInfo
