+## How to create dynamic Lua scripts
|
|
|
+
|
|
|
+ Similar to static files, upload a Lua script called "http/[name].lua where you replace [name] with the script's name.
|
|
|
+ The script should return a function that takes two parameters:
|
|
|
+
|
|
|
+ return function (connection, args)
|
|
|
+ -- code goes here
|
|
|
+ end
|
|
|
+
|
|
|
+ Use the _connection_ parameter to send the response back to the client. Note that you are in charge of sending the HTTP header.
|
|
|
+ The _args_ parameter is a Lua table that contains any arguments sent by the client in the GET request.
|
|
|
+
|
|
|
+ For example, if the client requests _http://2.2.2.2/foo.lua?color=red_ then the server will execute the function
|
|
|
+ in your Lua script _foo.lua_ and pass in _connection_ and _args_, where _args.color == "red"_.
