- Use lj-releng or luacheck to identify global variable references.
Tips
- You can cache
ngx to a local variable.
local ngx = ngx
- Always include
_VERSION in your module. For example, in the conn module,
local _M = {
_VERSION = "0.0.1"
}
local mt = { __index = _M }
function _M.new(options)
local self = { ... }
return setmetatable(self, mt)
end
function _M.access(self, remote_addr)
...
end
return _M
- You can call the preceding functions via
require('conn').new({}) and filter:access(remote_addr) where filter is an object of conn.
