nodejs http 发送请求

在近期的项目重构中，需将前后端独立开来，前端并不与MONGODB直接打交道，通过HTTP调用后端提供的RESTful进行数据交互，Node做为中间层，负责向模板填充数据。使用http模块发起请求

GET请求

var http = require('http');

var qs = require('querystring');

var data = {
a: 123,
time: new Date().getTime()};//这是需要提交的数据

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();

POST请求

var http = require('http');

var qs = require('querystring');

var post_data = {
a: 123,
time: new Date().getTime()};//这是需要提交的数据

var content = qs.stringify(post_data);

var options = {
hostname: '127.0.0.1',
port: 10086,
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);
});
});

req.on('error', function (e) {
console.log('problem with request: ' + e.message);
});

// write data to request body
req.write(content);

req.end();
