A simple and easy-to-use MVC framework for NPL Web application. If you are familiar with the jsp/servlet or asp.net mvc, you'll like this.
www/controller/DemoController.lua
local demoController = commonlib.gettable("nwf.controllers.DemoController");
-- http://localhost:8099/demo/sayHello
function demoController.sayHello(ctx)
-- you can access request, response, session here
-- local req = ctx.request;
-- local res = ctx.response;
-- local session = ctx.session;
return "test", {message = "Hello, Elvin!"}; -- return www/view/test.html
endwww/view/test.html
<!DOCTYPE html>
<html>
<head>
<title>{{title}}</title>
</head>
<body>
<h1>{{message}}</h1>
</body>
</html>www/controller/DemoController.lua
local demoController = commonlib.gettable("nwf.controllers.DemoController");
-- return json string
function demoController.testJson(ctx)
return {message = "hello, elvin!", remark = "test json result"}; -- just need to return a table
endJson Result
{"remark":"test json result","message":"hello, elvin!"}www/controller/PayController.lua
function payController.getQRCode(ctx)
local request = ctx.request;
local string_util = commonlib.gettable("nwf.util.string");
local tb = { appid = constant.WECHAT_PAY_APPID,
mch_id = constant.WECHAT_PAY_MCHID,
nonce_str=string_util.new_guid(),
body = "xxxxxxxx",
out_trade_no = 123,
total_fee = 1 * 100,
spbill_create_ip = request:getpeername(),
notify_url = "https://www.xxx.com/api/pay/callback",
trade_type = "NATIVE",
product_id = '1111111'};
tb.sign = sign(tb);
-- return a async page
return function (ctx, render)
payService.test(tb, function(data)
render(data); -- json result
--render("test", {message="async response", data=data}) -- view result
end)
end;
endwww/service/PayService.lua
function payService.test(tb, callback)
System.os.GetUrl({url = "https://api.mch.weixin.qq.com/pay/unifiedorder",
form = {data = table2XML(tb) } },
function(status, msg, data)
local ret = false;
if(status == 200) then
ret = luaXml2Table(ParaXML.LuaXML_ParseString(data));
end
callback(ret);
end
);
endYou only need to run the following command:
- ~ $ cd ~/workspace
- ~/workspace $ curl -O https://raw.githubusercontent.com/elvinzeng/nwf/master/nwf_init.sh
- ~/workspace $ sh ./nwf_init.sh "project-name"
Then, this script will use parameter "project-name" to create a directoty as project root directory, it will generate the necessary directory structure and the basic file automatically.
tips: you can use git-bash to run script if you are Windows user.
- Linux: sh start.sh
- Windows: run update_packages.sh and then run start_win.bat
- Access "http://localhost:8099/ ". "it works!" means web application is start success.
