错误：在对的NodeJS get调用的getaddrinfo ENOTFOUND [英] Error: getaddrinfo ENOTFOUND in nodejs for get call

问题描述

我运行code，对于它下面

I am running a web server on node the code for which is given below

var restify = require('restify');

var server = restify.createServer();

var quotes = [
  { author : 'Audrey Hepburn', text : "Nothing is impossible, the word itself says 'I'm possible'!"},
  { author : 'Walt Disney', text : "You may not realize it when it happens, but a kick in the teeth may be the best thing in the world for you"},
  { author : 'Unknown', text : "Even the greatest was once a beginner. Don't be afraid to take that first step."},
  { author : 'Neale Donald Walsch', text : "You are afraid to die, and you're afraid to live. What a way to exist."}
];

server.get('/', function(req, res) {
  res.json(quotes);
});

server.get('/quote/random', function(req, res) {
  var id = Math.floor(Math.random() * quotes.length);
  var q = quotes[id];
  res.json(q);
});

server.get('/quote/:id', function(req, res) {
  if(quotes.length <= req.params.id || req.params.id < 0) {
    res.statusCode = 404;
    return res.send('Error 404: No quote found');
  }

  var q = quotes[req.params.id];
  res.json(q);
});

server.listen(process.env.PORT || 3011);

然后我要做好以下code一个GET请求

And then i want to do a get request in the following code

var https = require('http');

/**
 * HOW TO Make an HTTP Call - GET
 */
// options for GET
var optionsget = {
    host : 'http://localhost',
    port : 3010,
    path : '/quote/random', // the rest of the url with parameters if needed
    method : 'GET' // do GET
};

console.info('Options prepared:');
console.info(optionsget);
console.info('Do the GET call');

// do the GET request
var reqGet = https.request(optionsget, function(res) {
    console.log("statusCode: ", res.statusCode);
    // uncomment it for header details
//  console.log("headers: ", res.headers);


    res.on('data', function(d) {
        console.info('GET result:\n');
        process.stdout.write(d);
        console.info('\n\nCall completed');
    });

});

reqGet.end();
reqGet.on('error', function(e) {
    console.error(e);
});

我刚开始用的节点，我甚至不知道这是正确的方式。
我想测试前preSS和restify.I的性能都做了服务器codeI一个apache的基准测试中写道，发现矛盾的是的RESTify我better.So想打电话来测试多一些结果远程服务，再后来读写mongodb.The高于code是我的出发point.I正在错误

I am just starting with node and i dont even know if this is the right way. I want to test the performance of express and restify.I have done a apache benchmark test for the server code i wrote and found contradicting results that restify is better.So i want to test out some more by making calls to remote services and then later read write to mongodb.The above code is my starting point.I am getting the error

{ [Error: getaddrinfo ENOTFOUND] code: 'ENOTFOUND', errno: 'ENOTFOUND', syscall: 'getaddrinfo' }

我是ATLEAST在写方向前进吗？什么是什么样的，我要测试的正确方法？为什么我得到的结果比的RESTify前preSS更快？任何人都可以引导我的最佳切入点教程中节点/ EX preSS /骨干网的应用和MongoDB？

Am i atleast heading in the write direction? What is the right way to the kind of tests that i want to? Why did i get the result restify faster than express? Can anyone guide me to the best starting point tutorials for application in node/express/backbone and mongodb?

推荐答案

的getaddrinfo ENOTFOUND意味着客户端无法连接到指定的地址。
请尝试指定主机不包含http：

getaddrinfo ENOTFOUND means client was not able to connect to given address. Please try specifying host without http:

var optionsget = {
    host : 'localhost',
    port : 3010,
    path : '/quote/random', // the rest of the url with parameters if needed
    method : 'GET' // do GET
};

关于学习资源，如果你开始与 http://www.nodebeginner.org/ ，然后你会不会出问题通过一些好书来获得更深入的了解 - 我建议专业的Node.js ，但有许多出那里。

Regarding learning resources, you won't go wrong if you start with http://www.nodebeginner.org/ and then go through some good book to get more in-depth knowledge - I recommend Professional Node.js , but there's many out there.
