本文实例讲述了nodejs使用http模块发送get与post请求的方法。分享给大家供大家参考，具体如下：

GET请求

var http = require('http');
var querystring = require('querystring');
var data = {
 a: 123,
 time: new Date().getTime()};//这是需要提交的数据
var content = querystring.stringify(data);
var options = {
 hostname: '127.0.0.1',
 port: 3000,
 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();

POST请求

var http = require('http');
var querystring = require('querystring');
var post_data = {
 a: 123,
 time: new Date().getTime()};//这是需要提交的数据
var content = querystring.stringify(post_data);
var options = {
 hostname: '127.0.0.1',
 port: 3000,
 path: '/pay/pay_callback',
 method: 'POST',
 headers: {
 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
 }
};
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);
 //JSON.parse(chunk)
 });
});
req.on('error', function (e) {
 console.log('problem with request: ' + e.message);
});
// write data to request body
req.write(content);
req.end();

希望本文所述对大家nodejs程序设计有所帮助。
