Here's my code to generate Gophermaps for posts on a Hexo site.

I cannot guarantee this will work on your Hexo site. I had custom multilingual support on my site,
and manually removed all language related stuff from this code snippet. I did not test that the 
code still functions after this modification.

Usage:

Put gopher.js into "scripts" folder of your theme, e.g. "themes/lantian/scripts/gopher.js".

local lantian_whois = {}

function lantian_whois.file_exists(subdir, target)
    if target == nil then return false end
    local f = io.open(ngx.var.document_root .. "/" .. subdir .. "/" .. string.gsub(target, "/", "_"), "rb")
    if f == nil then return false end
    f:close()
    return true
end
