if (FALSE) {
library(amapGeocode)

# Before the `getLocation()` is executed,
# the token should be set by `option(amap_key = 'key')`
# or set by key argument in `getLocation()`

# Get reverse-geocode as a table
getLocation(104.043284, 30.666864)
# Get reverse-geocode as a XML
getLocation("104.043284, 30.666864", output = "XML")
