實用技巧：如何通過IP地址進行精準定位

在甲方工作的朋友可能會遇到這樣的問題，服務器或者系統經常被掃描，通過IP地址我們只能查到某一個市級城市，如下圖：

當我們想具體到街道甚至門牌號，該怎么辦？？？

偶然間發現百度地圖有高精度IP定位API的接口，通過該接口我們可以通過IP地址定位到具體的地理位置，甚至能精確到門牌號及周圍的標志性建筑。

若想要使用該接口進行查詢，必須先申請一個密鑰（AK），如下圖：

申請過程就不進行說明了。API的接口參數說明和返回參數說明也不過多的介紹，大家可以看一看。因為我想返回基礎定位結果+地址信息+POI信息，所以我將請求參數extensions的值設置為3。一次完整的http請求為：“你的 密鑰（AK）” &coord=bd09ll&extensions=3 。請求結果如下圖：

結果為json格式數據：

{"content":{"location":{"lat":23.06588,"lng":115.404586},"locid":"925a2a9e3ac5be1cf003afd23c344ab3","radius":30,"confidence":0.5,"address_component":{"country":"中國","province":"廣東省","city":"汕尾市","district":"海豐縣","street":"新平路","street_number":"","admin_area_code":441521},"formatted_address":"廣東省汕尾市海豐縣新平路","business":"公平"},"result":{"error":161,"loc_time":"2016-10-19 21:53:28"}}

我們需要的字段為：content字段里面的formatted_address。當然我們也可以將location里面的經度和緯度提取出來從而顯示在地圖上面。有的IP地址會返回pois數據，比如：183.55.116.95。返回參數如下：

{"content":{"location":{"lat":23.082367,"lng":115.466276},"locid":"3fb96555906fff3100ff21119142ccd5","radius":30,"confidence":1.0,"address_component":{"country":"中國","province":"廣東省","city":"汕尾市","district":"海豐縣","street":"S335","street_number":"","admin_area_code":441521},"formatted_address":"廣東省汕尾市海豐縣S335","pois":[{"name":"雙墩村","address":"汕尾市海豐縣三三五省道","tag":"行政地標;村莊","location":{"lat":23.082422,"lng":115.465348},"uid":"18010998377147269119"},{"name":"雙墩村委會","address":"汕尾市海豐縣","tag":"政府機構;各級政府","location":{"lat":23.083394,"lng":115.465914},"uid":"17661602237861855231"},{"name":"長聯塘尾","address":"汕尾市海豐縣","tag":"行政地標;村莊","location":{"lat":23.081358,"lng":115.467315},"uid":"18010998372852301823"},{"name":"雙墩小學","address":"335省道附近","tag":"教育培訓;小學","location":{"lat":23.083336,"lng":115.465061},"uid":"17661601958688980991"},{"name":"大溪頭","address":"汕尾市海豐縣","tag":"行政地標;村莊","location":{"lat":23.090326,"lng":115.465995},"uid":"18010998368557334527"}],"location_description":"雙墩村東104米"},"result":{"error":161,"loc_time":"2016-10-19 22:03:31"}}

此時我們可以把pois字段也提取出來，值得注意的是pois為數組，我們可以遍歷數組數據。

通過上面的分析，用python簡單的寫了一個腳本，具體代碼如下：

# -*- coding:utf-8 -*-
# author:allen權
import sys import urllib2 import json def get_ip_information(ip): url='http://api.map.baidu.com/highacciploc/v1?qcip='+ip+'&qterm=pc&ak='你的密鑰（AK）'&coord=bd09ll&extensions=3' poiss='' request = urllib2.Request(url) page = urllib2.urlopen(request, timeout=10) data_json = page.read() data_dic = json.loads(data_json) if(data_dic.has_key("content")): content=data_dic["content"] address_component=content["address_component"] formatted_address=content["formatted_address"] print "該IP地址的具體位置為：" print address_component["country"] print formatted_address if (content.has_key("pois")): print "該IP地址附近POI信息如下：" pois = content["pois"] for index in range(len(pois)): pois_name = pois[index]["name"] pois_address = pois[index]["address"] print pois_name, pois_address else: print 'IP地址定位失敗！！！' if __name__ == '__main__': get_ip_information('183.55.116.95')

大家把腳本上面的參數ak值改為自己的密鑰即可。測試截圖如下：

再放一張自己IP的測試截圖：
