| -- This example depends on "luajit-geoip". |
| -- It illustrates how to connect to GeoIP and use it to look up country of an IP address. |
| -- It can be used in plugin.config with the lua plugin. |
| |
| -- Setup Instructions |
| -- 1) install GeoIP - 1.6.12 |
| -- 2) install GeoIP legacy country database - https://dev.maxmind.com/geoip/legacy/install/country/ |
| -- 3) install luajit-geoip (https://github.com/leafo/luajit-geoip) |
| -- or just copy geoip/init.lua from the repo to /usr/local/share/lua/5.1/geoip/init.lua |
| -- 4) You may need to make change so luajit-geoip does ffi.load() on /usr/local/lib/libGeoIP.so |
| |
| ts.add_package_path("/usr/local/share/lua/5.1/?.lua") |
| |
| local geoip = require "geoip" |
| |
| function do_global_send_response() |
| local res = geoip.lookup_addr("8.8.8.8") |
| ts.client_response.header["X-Country"] = res.country_code |
| end |
