NodeJS创建http client

 1 var http = require('http');
 2 
 3 var data = JSON.stringify({ 'important': 'data' });
 4 var cookie = 'something=anything'
 5 
 6 var client = http.createClient(80, 'www.example.com');
 7 
 8 var headers = {
 9     'Host': 'www.example.com',
10     'Cookie': cookie,
11     'Content-Type': 'application/json',
12     'Content-Length': Buffer.byteLength(data,'utf8')
13 };
14 
15 var request = client.request('POST', '/', headers);
16 
17 // listening to the response is optional, I suppose
18 request.on('response', function(response) {
19   response.on('data', function(chunk) {
20     // do what you do
21   });
22   response.on('end', function() {
23     // do what you do
24   });
25 });
26 // you'd also want to listen for errors in production
27 
28 request.write(data);
29 
30 request.end();
