'request' 之于 node.js 如 'httpclient' 之于 Java

1. 安装所需Module先

npm install -g request

2. 若请求无须经过代理服务器时

var request = require('request');
 
request('http://www.baidu.com', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body);
  }else{
    console.error(error);
  }
});

3. 若请求须经过代理服务器时

var request = require('request');
var proxiedRequest = request.defaults({proxy: "http://username:password:proxy.com "});
proxiedRequest ('http://www.baidu.com', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body);
  }else{
    console.error(error);
  }
});
