Java根據地名獲取所在省，市，縣

設計思想，首先調用百度地圖API查詢地名對應的經度和緯度，然后根據經度和緯度查詢所在省，市，縣

 python獲取本機的外網IP：

import requests
import re

def getIP():
    headers = {}
    headers['User-Agent'] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36"
    response = requests.get('http://txt.go.sohu.com/ip/soip',headers=headers)
    html = response.text
    reGET = re.compile(r'\d+.\d+.\d+.\d+.').findall(html)
    for i in reGET:
        print('外網地址： %s'%i)
getIP()
