java基站定位接口实例

大家好，欢迎来到IT知识分享网。

该接口基于LBS数据仓库

接口地址：http://api.cellocation.com:81/cell/

支持格式： CSV/JSON/XML
请求方式： GET

请求示例：http://api.cellocation.com:81/cell/?mcc=460&mnc=1&lac=4301&ci=20986&output=xml

返回数据格式：CSV
errcode,纬度,经度,精度半径,地址

errcode
0: 成功
10000: 参数错误
10001: 无查询结果

示例：
0,39.999024,116.476159,222,”北京市朝阳区望京街道北京市望京实验学校(宝星分校);阜安路与宏泰东街路口西231米”
