参数 | 值 |
---|---|
Latitude: | |
Longitude: | |
pois(是否显示周边100米内poi): | |
(结果显示如下)
http://api.map.baidu.com/geocoder/v2/?ak=您的密钥& callback=renderReverse&location=28.696117,115.958458&output=json&pois=1
坐标:(115.95845796638,28.696117043877)对应的地址是: 江西省南昌市青山湖区创新路1号
该点周边100米内有10个poi
状态字段:
名称 | 类型 | 说明 |
---|---|---|
status | constant | 返回结果状态值, 成功返回0,其他值请查看附录。 |
location | lat | 纬度坐标 |
lng | 经度坐标 | |
formatted_address | 结构化地址信息 | |
business | 所在商圈信息,如 "人民大学,中关村,苏州街" | |
addressComponent | city | 城市名 |
district | 区县名 | |
province | 省名 | |
street | 街道名 | |
street_number | 街道门牌号 | |
pois(周边poi数组) | addr | 地址信息 |
cp | 数据来源 | |
distance | 离坐标点距离 | |
name | poi名称 | |
poiType | poi类型,如’ 办公大厦,商务大厦’ | |
point | poi坐标{x,y} | |
tel | 电话 | |
uid | poi唯一标识 | |
zip | 邮编 |

特别说明:
1.因为Geocoding和反Geocoding使用的门址数据以及算法都不是一样的,所以会出现不能一一对应的现象。
2.逆地址解析location参数传入的参数格式是(纬度lat,经度lng)。
