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，該怎麼辦？？？
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誌性建築。該接口的說明地址為：
http://lbsyun.baidu.com/index.php?title=webapi/high-acc-ip
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：
v1?qcip=183.55.116.90&qterm=pc&ak=
“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字段裡面的formatted_address。當然我們也可以將location裡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 indexin 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：(不是我本人的ip。2223333）
