如何從express js撥打電話以休息api？

-1

我建立了rest api，它們在端口8080上運行。我創建了express project，它運行於端口3000。如何從express js撥打電話以休息api？

如何撥打rest api來獲取數據？

我app.js是

/** 
* Module dependencies. 
*/ 

var express = require('express') 
    , routes = require('./routes') 
    , user = require('./routes/user') 
    , http = require('http') 
    , path = require('path'); 

var bodyParser = require("body-parser"); 
var jquery = require('jquery'); 
var app = express(); 

// all environments 
app.set('port', process.env.PORT || 3000); 
app.set('views', __dirname + '/views'); 
app.set('view engine', 'ejs'); 
app.use(express.favicon()); 
app.use(express.logger('dev')); 
app.use(express.bodyParser()); 
app.use(express.methodOverride()); 
app.use(app.router); 
app.use(express.static(path.join(__dirname, 'public'))); 
app.use(bodyParser.urlencoded({ extended: false })); 
app.use(bodyParser.json()); 

// development only 
if ('development' == app.get('env')) { 
    app.use(express.errorHandler()); 
} 

app.get('/', routes.index); 
app.get('/users', user.list); 

app.post('/login', function(req, res){ 
    console.log("User name = "+req.body.email+", password is "+req.body.password); 
    var data = { 
      email:req.body.email, 
      password:req.body.password 
     }; 

    jquery.ajax({ 
     type: 'POST', 
     data: JSON.stringify(data), 
     contentType: 'application/json', 
     dataType:"json", 
     url: 'http://localhost:8080/LT/login',      
     success: function(data) { 
      console.log('success'); 
      console.log(JSON.stringify(data)); 
      if(data.accessToken!='') 
      { 
       alert("login success"); 
      } 
     }, 
     error:function(data){ 
      console.log('error'); 
      console.log(data); 
     } 
    }); 
    console.log('Vishwas'); 
}); 


http.createServer(app).listen(app.get('port'), function(){ 
    console.log('Express server listening on port ' + app.get('port')); 
});

我index.ejs是
