Sample programs that use Nodejs how to read memcache

  I mainly introduced the use of Nodejs how to read the Memcache sample program, we refer to the use of the bar

The code is as follows: var memcache = require (' memcache ')    , HTTP = require (' http ')    , url = require (' URL ') &nbs P  , QS = require (' querystring ')    , memsettings = {port:2000, host: ' 10.6.0.6 '}    , Httpse Ttings = {port:3000}    , cacheobject = {}    , httpserver    , client    , RequestHandler;   client = new Memcache. Client (Memsettings.port, memsettings.host); ... client.on (' Connect ', function () {    client.connected = true;});   Client.on (' Close ', function () {   //No arguments-connection has been closed     Client.conn ected = false; });   function GetData (key, wrapper, Res) {    client.get (key, function (error, result) {      &N Bsp    //All of the callbacks have two arguments.            //' result ' may contain things which aren ' t great, but       &NBS P   &nbsp Aren ' t really errors, like ' not_stored '             if (!error) {      &NBS P         if (result) {                    cacheobject[ Key] = result;                     Res.write (wrapper + ' (' + result + ') ');                } else {                & nbsp   Res.write (' no data ');                                 Res.end ( );             {     };    /*if (Cacheobject[key]) {        Response.Write (Cacheobject[key);         Response.End ();    } else  {        client.get (key, function (error, result) {      &NB Sp     //All of the callbacks have two arguments.            //' result ' may contain things which aren ' t great, but       &NBS P    //aren ' t really errors, like ' not_stored '             if (!error) {  &nbs P             Cacheobject[key] = result;                 cacheobject[key][' timeoutid ' = settimeout (function () {  &nbs P                 client.get (key, function (error, result) {      &NBS P                 if (!error) {              &NBSP ;             Cacheobject[key] = result;                                   & nbsp        });                });                 Response.Write (result);                 Response.End ();            }        }    }*/}   Httpserver = Http.createserver (function (req, res) {    var urlobj, Queryobj;   & nbsp Urlobj = Url.parse (Req.url);     Res.writehead, {"Content-type": "Text/javascript; Charset=utf-8 "});     Queryobj = Qs.parse (urlobj.query);     Path = Queryobj.pathname;     if (queryobj.gid) {        GetData (Queryobj.gid, queryobj.callback| | Callback ', RES);    } else {        res.write (' no input ');         res.end ();   &N Bsp }     *     switch (urlobj.pathname) {        case '/pai ':       &N Bsp     RES.WRITe (urlobj.pathname);         break;         case '/qiang ':           Res.write (urlobj.pathname);         break;         default:             res.write (' Default ');         break;    }     Res.end ();     *});   Client.connect (); Httpserver.listen (Httpsettings.port); Console.log (' HTTP server listening on ' + Httpsettings.port);
