python获取外网ip地址的方法总结

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]) );

希望本文所述对大家的Python程序设计有所帮助。
