本文实例总结了python获取外网ip地址的方法。分享给大家供大家参考。具体如下：

一、利用脚本引擎库直接获取

import console;
import web.script
import inet.http;
var jsVm = web.script(\"JavaScript\")
jsVm.AddCode( inet.http().get(\"http://fw.qq.com/ipaddress\") )
var ipAddr = jsVm.CodeObject.IPData[0];
console.log( \"您的外网IP地址:\",ipAddr )

二、http库，模式匹配获取

import inet.http;
getIp = function(){
  var http = inet.http()
  http.flags = 0x80000000/*_INTERNET_FLAG_RELOAD强制文件从服务器下载不是缓存*/
      | 0x4000000/*_INTERNET_FLAG_DONT_CACHE*不缓存数据*/
  var str = http.get(\"http://fw.qq.com/ipaddress\")
  return str?string.match(str,\'\"(.+?)\"\')
}
io.open()
io.print(getIp())

三、whttp库，模式匹配获取

//获取IP
import inet.whttp;
getIp = function(){  
  var whttp = inet.whttp()  
  var str = whttp.get(\"http://www.ip138.com/ip2city.asp? r=\"+tonumber(time.now()))
  whttp.close()
  return str?string.match(str,\"\\[(.*?)\\]\");
    
}
io.open()
io.print(getIp())

四、API方法

io.open();
var IPHLPAPI = raw.loadDll(\"IPHLPAPI.DLL\")
var GetIpAddrTable = IPHLPAPI.api(\"GetIpAddrTable\",\"int(struct &pIpAddrTable,int &pdwSize,int border)\")
IPInfo = class {
  int dwAddr;
  int dwIndex;
  int dwMask;
  int dwBCastAddr;
  int dwReasmSize;
  word unused1;
  word unused2  
}
var PMIB_IPADDRTABLE = class {
  int dEntrys;
  struct mIPInfo[255] = { ..IPInfo() };
}
var ipStruct = PMIB_IPADDRTABLE();
var re, ipStruct, ret = GetIpAddrTable(ipStruct, 0, 1);
var re, ipStruct, ret = GetIpAddrTable(ipStruct, re, 0);
var ipData = ipStruct.mIPInfo[ipStruct.dEntrys - 1].dwAddr;
var ip = raw.convert({ int n = ipData }, { BYTE data[4] });
io.print( string.format(\"%d.%d.%d.%d\", ip.data[1], ip.data[2], ip.data[3], ip.data[4]) );
