I am using lua as server page for the authentication. after the authentication i wnt to retaun a value to the angular js. I simply cheked for for a string retun , bbut it will not work ..plaese anybody knows how to solve it ? How to return the values..

this is my lua script

require "string"
require 'apache2'
--require "json"
json = require 'json'
function handle(r)
local POST, POSTMULTI = r:parsebody()
local name = POST['username']
local user =""
r.content_type = "text/plain"
local result = {}
local file1 = io.open("/var/www/html/login/test.json", "r")
 local contents = file1:read( "*all" )
r:puts("" .. contents)
 return "hello"
end

but it is not returned in the angular ...this is the right method for return values.?

Hi. This links is only for portuguese brazilian.

about you question:

-- did you using mod_lua* from apache2 ?

-- http response "returns":

- header

- body

can't be 'return' a value to angular.

* documentation of mod_lua -> https://httpd.apache.org/docs/trunk/mod/mod_lua.html

Hiii....Denis

Thanks for the replay. Yes I am using Mod_lua apache2. Is Mod_lua doesn't return value to angular ?. If there is any other method to return values from mod_lua to angular . And thanks for the documentation link attached.

Vinu the scope are different.

When angular and/or browser request a call to server (ajax, get, post, ...) it will retrive the * http header|body * not a 'value'. 

An value can be returned, but, using http status code (like 200, 201, ...)

checkout mod_lua documentation have several examples.

Addenum:  mod_lua alternatives --> http://lua.space/webdev/the-best-lua-web-frameworks <--
