比來項目某個功效須要依據ip地址從第三方接口獲得具體的地輿地位,從網上找了許多例子,重要接口有新浪的,淘寶的,騰訊的。試了淘寶的,假如是數目級小的還可以,假如數目級到達上十萬級就速度慢了,會招致體系瓦解。上面例子是新浪的,例子不是合適每一個項目,須要改一下.
/** ipSearchUrl=http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip=(這是新浪的接口地址) 在項目中新浪的接口地址沒有直接寫逝世,而是去讀屬性文件。 */ public static String getIpInfoBySina(String ip){ // 讀取屬性文件(屬性文件key-value和格局) final String PROP_IPSEARCHURL="ipSearchUrl"; final String RET_SUCCESS="1"; final String RET="ret"; final String PROVINCE="province"; final String CITY="city"; final String DISTRICT="district"; final String ISP="isp"; String ipAddress=""; if(StringUtils.isBlank(ip)){ return null; } String url = SystemParamPropertyUtils.getSystemParamKeyValue(PROP_IPSEARCHURL);//這個是附屬性文件中獲得url,即新浪接口地址 if(StringUtils.isNotBlank(url)){ String path=url+ip;//"http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip="+ip; HttpClient httpClient = new HttpClient(); Map<String, String> paramMap = new HashMap<String, String>(); String remoteIpInfo=""; try { remoteIpInfo = HttpClientUtil.request(httpClient, path, paramMap,"sina"); } catch (Exception e) { e.printStackTrace(); } if(StringUtils.isNotBlank(remoteIpInfo)){ String _ret=searchValue(remoteIpInfo, RET); if(RET_SUCCESS.equals(_ret)){ String provinceName=searchValue(remoteIpInfo, PROVINCE); String cityName=searchValue(remoteIpInfo, CITY); String district=searchValue(remoteIpInfo, DISTRICT); String isp=searchValue(remoteIpInfo, ISP); ipAddress=provinceName+cityName+district+isp; } } } return ipAddress; } private static String searchValue(String remoteIpInfo,String key){ String _value=""; if(StringUtils.isNotBlank(remoteIpInfo)){ _value=StringUtils.substringBetween(remoteIpInfo,"\""+key+"\":", ","); if(StringUtils.isNotBlank(_value)){ _value=UnicodeUtils.decodeUnicode(_value); } } return _value; }
讀新浪的接口地址很快,我自己測試到了九萬條閣下,非常鐘。淘寶的話一個多小時,五萬多條。還有一個小技能,就是把讀到的ip存到map中,然後下次讀的話就直接從map掏出,如許快許多。這個會衍生出許多成績,當日記文件到達百萬級,萬萬級,怎樣處理。相似淘寶如許的,一秒若干定單,每一個定單ip紛歧樣。我不曉得怎樣處理。有年夜神曉得回我一下。
上面是用淘寶的。
