如何用Python编写工具来查询并获取当前设备的IP地址？

python获取IP地址并判断其有效性import requestsfrom lxml import etreeimport time

headers={ User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)}

def get_ip_address(): url=http://api.ip.cn/ response=requests.get(url, headers=headers) time.sleep(1) # 避免频繁请求

if response.status_code==200: ip_info=response.text print(ip_info) tree=etree.HTML(ip_info) ip=tree.xpath('//div[@id=ip]/text()')[0] print(当前IP:, ip)

if 无效 not in ip_info: print(地址有效，保存成功。) # 保存IP地址 with open(valid_ip.txt, w) as file: file.write(ip) else: print(地址无效。) else: print(请求失败。)

get_ip_address()

一、获取IP地址

二、判断地址是否可用。并把可的地址保存。

import requestsfrom lxml import etreeimport timeheaders = { "User-Agent": "Mozilla/5.0(Windows NT 6.1;WOW64) AppleWebKit/537.36(KABUL, like Gecko) " "Chrome/86.0.4240.198Safari/537.36 " }url = "www.66ip.cn/areaindex_10/"for page in range(1, 11): page_url = url + str(page) + ".html" resp = requests.get(url=page_url, headers=headers) resp.encoding = resp.apparent_encoding e = etree.HTML(resp.text) ips = e.xpath("//div[1]/table//tr/td[1]/text()") ports = e.xpath("//div[1]/table//tr/td[2]/text()") addrs = e.xpath("//div[1]/table//tr/td[3]/text()") # print(ips) # print(ports) # print(addrs) with open("06-IP代理.txt","w",encoding="utf-8") as f: for i,p,a in zip(ips,ports,addrs): f.write(f"---{i}---{p}---{a}\n") time.sleep(5)print("保存完毕")

import requestsfrom lxml import etreeimport timeheaders = { "User-Agent": "Mozilla/5.0(Windows NT 6.1;WOW64) AppleWebKit/537.36(KABUL, like Gecko) " "Chrome/86.0.4240.198Safari/537.36 " }url = "www.66ip.cn/areaindex_10/"for page in range(1, 11): page_url = url + str(page) + ".html" resp = requests.get(url=page_url, headers=headers) resp.encoding = resp.apparent_encoding e = etree.HTML(resp.text) ips = e.xpath("//div[1]/table//tr/td[1]/text()") ports = e.xpath("//div[1]/table//tr/td[2]/text()") addrs = e.xpath("//div[1]/table//tr/td[3]/text()") # print(ips) # print(ports) # print(addrs) for ip,port in zip(ips,ports): if ip != 'ip': proxies_dict = { "" + ip + ':' + port, } print(proxies_dict) try: res = requests.get(url="www.baidu.com", headers=headers, proxies=proxies_dict, timeout=2) res.encoding = res.apparent_encoding if res.status_code == 200: with open("06-IP代理-可用.txt","a",encoding="utf-8") as f: f.write(f"{ip}---{port}\n") except: print("当前代理不可用") time.sleep(3)print("保存完毕")

1、xpath解析数据。

e = etree.HTML(resp.text)ips = e.xpath("//div[1]/table//tr/td[1]/text()")

2、txt文本格式保存数据。

with open("06-IP代理.txt","w",encoding="utf-8") as f: for i,p,a in zip(ips,ports,addrs): f.write(f"---{i}---{p}---{a}\n")
