Node.js发送HTTP客户端请求并显示响应结果的方法示例

var http = require('http');var url = require('url');var util = require('util');var argUrl = process.argv[2];var parsedUrl = url.parse(argUrl, true);var options = {host: null, port: -1, path: null, method: 'GET'};options.host = parsedUrl.hostname;options.port = parsedUrl.port;options.path = parsedUrl.pathname;if (parsedUrl.search) options.path += "?" + parsedUrl.search;var req = http.request(options, function(res){  util.log('STATUS: ' + res.statusCode);  util.log('HEADERS: ' + util.inspect(res.headers));  res.setEncoding('utf8');  res.on('data', function(chunk){    util.log('BODY: ' + chunk);  });  res.on('error', function(err){    util.log('RESPONSE ERROR: ' + err);  });});req.on('error', function(err){  util.log('REQUEST ERROR: ' + err);});req.end();

var http = require('http');var querystring = require('querystring');var contents = querystring.stringify({  name: 'joey',  email: 'joey@joey.com',  address: 'joey university'});var options = {  host: 'www.joey.com',  path: '/application/node/post.php',  method: 'POST',  headers: {    'Content-Type': 'application/x-www-form-urlencoded',    'Content-Length': contents.length  }};var req = http.request(options, function(res){  res.setEncoding('uft8');  res.on('data', function(data){    console.log(data);  });});req.write(contents);req.end(); //不能漏掉，结束请求，否则服务器将不会收到信息。
