var http = require('http'); 
var qs = require('querystring'); 
var data = { 
 a: 123, 
 time: new Date().getTime()};//這是需要提交的數(shù)據(jù) 
var content = qs.stringify(data); 
var options = { 
 hostname: '127.0.0.1', 
 port: 10086, 
 path: '/pay/pay_callback?' + content, 
 method: 'GET' 
}; 
 
var req = http.request(options, function (res) { 
 console.log('STATUS: ' + res.statusCode); 
 console.log('HEADERS: ' + JSON.stringify(res.headers)); 
 res.setEncoding('utf8'); 
 res.on('data', function (chunk) { 
 console.log('BODY: ' + chunk); 
 }); 
}); 
 
req.on('error', function (e) { 
 console.log('problem with request: ' + e.message); 
}); 
 
req.end();
