request examples

1.js

var request = require('request');

var url = 'http://www.google.com';

// basic use
request.get(url, function(err, response, body) {
  if (err) {
    console.log("Error:", err);
  } else {
    // response.body == body
    console.log("Body:", body);
  }
});

2.js

var request = require('request');

// build the request URL
var requestURL = 'https://' + 'www.google.com';

// specifying other request properties, like headers
var requestOptions = {
  url: requestURL,
  headers: {
    'User-Agent': "this can be anything"
  }
};

request.get(requestOptions, function(err, response, body) {
  if (err) {
    console.log("Error:", err);
  } else {
    // response.body == body
    console.log("Body:", body);
  }
});

3.js

var request = require('request');

// build the request URL
var requestURL = 'https://' + 'www.google.com';

// specifying other request properties, like headers
var requestOptions = {
  url: requestURL,
  headers: {
    'User-Agent': "this can be anything"
  }
};

request.get(requestOptions, function(err, response, body) {
  if (err) {
    console.log("Error:", err);
  } else {
    // the body is read here
    // response.body == body
    // console.log("Body:", body);
  }
})
  .on('error', function(err) {
    throw err;
  })
  .on('response', function(response) {
    console.log('status code:', response.statusCode);
    // the body is not yet read (response.body is undefined)
    console.log('response body:', response.body)
  });

4.js

// chaining async functions with callbacks

function getRepoContributors(owner, name, cb) {
  var url = '...';
  request.get(url, function(err, response, body) {
    if (err) {
      cb(err);
    } else {
      cb(null, body)
    }
  });
}


getRepoContributors('jquery', 'jquery', function(err, contributors) {
  if (err) {
    // handle it...
  } else {
    // I have an array of contributors
    doSomethingElseAsync(function(err, result) {
      // ...
    })
  }
})
