我想从 Grails 应用程序中的 IP 地址检索地理位置。
我尝试了 hostip和geoip都引发异常并且对我不起作用。有没有其他方法可以获取地理位置?
当我使用geoip时,我有:
配置.groovy:
geoip.data.resource= "/WEB-INF/GeoLiteCity.dat"
geoip.data.cache="GEOIP_STANDARD"
在我的控制器中:
GeoIpService geoIpService
index() {
def location = geoIpService.getLocation("85.176.52.75")
render location.countryName + " " + location.city
}
例外是:
