APP數據來源大致分三種:
1、線上數據
服務器端返回的數據,一般採用用HTTP或者HTTPS、SOCKET連接方式與APP客戶交互,可以返回json格式或者二進制。
local json = luaopen_cjson();
function HelperURLResponeFunc(urlresponse)
local urlrequest = urlresponse:getRequest();
if(urlrequest.thread ~= nil) then
--LXZMessageBox("urlrequest.thread:"..type(urlrequest.thread));
coroutine.resume(urlrequest.thread, urlresponse);
end
end
local service_host = "http://120.55.84.103:8080/";--服務器地址
local function HelperPostGetJSON(url, data, fn)
local co = coroutine.create(function (thread)
local urlrequest = _urlRequest:new();
urlrequest.nRequestType = eRequestPost;
urlrequest.func = "HelperURLResponeFunc";
urlrequest.url = url.."?";
for k,v in pairs(data) do
urlrequest.url = urlrequest.url ..k.."="..v.."&";
end
urlrequest.url = TrimRightChar(urlrequest.url, '&');
urlrequest.url = TrimRightChar(urlrequest.url, '?');
urlrequest.thread = thread;
--LXZMessageBox(urlrequest.url);
local curl = CLXZCurl:Instance();
curl:send(urlrequest);
local urlresponse = coroutine.yield();
if(fn~=nil) then
fn(urlresponse);
end
end);
coroutine.resume(co, co);
end
--從服務器獲取數據
local function OnServer(window, msg, sender)
local root=HelperGetRoot();--獲得根節點
local wnd=root:GetLXZWindow("id");--獲得id窗口
--創建協程,在協程裏可以順序執行異步代碼
HelperCoroutine(function(thread)
HelperPostGetJSON(service_host.."getid", {}, function(urlresponse)--異步調用接口
LXZMessageBox("urlresponse:getResponseData:"..urlresponse:getResponseData())
local res = json.decode(urlresponse:getResponseData());
if res then
HelperSetWindowText(wnd, res.id);
else
HelperSetWindowText(wnd, "從服務器獲取失敗");
end
coroutine.resume(thread);
end);
coroutine.yield();
end);
end
2、本地配置數據
可讀取key-value模式文本數據文件
--從配置文件讀取數據
local function OnCfg(window, msg, sender)
local root=HelperGetRoot();--獲得根節點
local wnd=root:GetLXZWindow("id");--獲得id窗口
local cfg = ILXZCoreCfg:new_local();
cfg:load(LXZAPIGetWritePath().."data.cfg");
local id = cfg:GetInt("id");
if id then
HelperSetWindowText(wnd, id);
else
HelperSetWindowText(wnd, "配置文件錯誤");
end
end
3、sqlite3數據庫
集成有sqlite數據庫,可直接跟sqlite交互。
--數據庫相關
local function DBInitialize(dbname)
LXZDoFile("sqlite3.lua"); --數據庫模塊
local corecfg = ICGuiGetLXZCoreCfg();
local dbfullpath = "";
if(corecfg.IsEditTool==true) then --如果是lae工具中.
dbfullpath = LXZAPIGetWritePath().."Edit"..dbname; --防止產生數據庫同名時無法同時打開。
else
dbfullpath = LXZAPIGetWritePath()..dbname;
end
--打開sqlite3
local db = sqlite3.open(dbfullpath);
db:exec("drop table Test"); --刪除存在的表
sql = "create table Test(id INTEGER PRIMARY KEY autoincrement, name VARCHAR(32), userid INTERGER)";
local d,err = db:exec(sql); --創建Test表,id作爲主鍵,自動增加,name名字可變長.
sql = "insert into Test(id,name,userid) values(100, \"我是個測試名字!\", 1111111)" --插入測試數據.
local d,err = db:exec(sql);
return db;
end
--文件加載時初始化.
local db=DBInitialize("TestData.db");
--從數據庫讀取數據
local function OnSqlite(window, msg, sender)
local root=HelperGetRoot();--獲得根節點
local wnd=root:GetLXZWindow("id");--獲得id窗口
local sql="select * from Test where id=100";
local d,err = db:exec(sql);
local users = HelperDBSelect(db, sql, true);
if users and users[1] then
HelperSetWindowText(wnd, users[1].userid);
else
HelperSetWindowText(wnd, "該數據不存在.");
end
end
1、測試程序界面
測試代碼:
LXZDoFile("LXZHelper.lua");
LXZDoFile("serial.lua");
local json = luaopen_cjson();
function HelperURLResponeFunc(urlresponse)
local urlrequest = urlresponse:getRequest();
if(urlrequest.thread ~= nil) then
--LXZMessageBox("urlrequest.thread:"..type(urlrequest.thread));
coroutine.resume(urlrequest.thread, urlresponse);
end
end
local service_host = "http://120.55.84.103:8080/";--服務器地址
local function HelperPostGetJSON(url, data, fn)
local co = coroutine.create(function (thread)
local urlrequest = _urlRequest:new();
urlrequest.nRequestType = eRequestPost;
urlrequest.func = "HelperURLResponeFunc";
urlrequest.url = url.."?";
for k,v in pairs(data) do
urlrequest.url = urlrequest.url ..k.."="..v.."&";
end
urlrequest.url = TrimRightChar(urlrequest.url, '&');
urlrequest.url = TrimRightChar(urlrequest.url, '?');
urlrequest.thread = thread;
--LXZMessageBox(urlrequest.url);
local curl = CLXZCurl:Instance();
curl:send(urlrequest);
local urlresponse = coroutine.yield();
if(fn~=nil) then
fn(urlresponse);
end
end);
coroutine.resume(co, co);

local res = json.decode(urlresponse:getResponseData());
if res then
HelperSetWindowText(wnd, res.id);

end
coroutine.resume(thread);

--事件綁定
local event_callback = {}
event_callback.__index = event_callback;
event_callback ["OnServer"] = OnServer;
event_callback ["OnSqlite"] = OnSqlite;
event_callback ["OnCfg"] = OnCfg;
--消息派發接口
function main_dispacher(window, cmd, msg, sender)
LXZAPI_OutputDebugStr("cmd 1:"..cmd);
if(event_callback[cmd] ~= nil) then --如果已經綁定
LXZAPI_OutputDebugStr("cmd 2:"..cmd);
event_callback[cmd](window, msg, sender);--則調用綁定的接口
end
